Safety FIG. 3: Read and understand this manual and the manual for all attachments before operating the combine.

Learn how to operate the combine and how to use the controls properly.

Do not operate the combine without instruction and training.

For your personal safety and the personal safety of others, follow all safety precautions and instructions found in the manual and on decals fastened to the combine and the attachments.

Personal injury or death can result if these precautions are not followed.

S-1123

FIG. 3 FIG. 4: Be prepared for an emergency. Always carry one or more suitable fire extinguishers - ABC rating, dry chemical, 2.2 kg (5 lb). Check fire extinguishers regularly to make sure extinguishers are properly charged and in operating condition.

Mounting a fire extinguisher near the cab and a fire extinguisher near the engine compartment is a recommendation.

To reduce the risk of fire, frequently remove crop material from the combine and engine platform and check for components becoming too hot.

Keep a first aid kit close for treatment of minor cuts and scratches.

S-1131

FIG. 4

FIG. 5: Wear close fitting clothing and personal protection equipment correct for operating or doing lubrication and maintenance on the combine. Tie up long hair to prevent the hair from becoming entangled in the moving parts.

m

WARNING: An operator must not use alcohol or drugs which can affect alertness or coordination. An operator taking prescription or over the counter drugs needs medical advice on whether or not the operator can properly operate machines.

S-1127A

FIG. 5

79027284 A Rev.

Safety FIG. 6: Face the ladder and use the handrails when getting on or off the combine.

Wc1940

FIG. 6 FIG. 7: Never operate the engine in a closed building unless exhaust is vented outside.

Wc1949

FIG. 7 FIG. 8: Make sure that all shields, guards, and access doors are in location and properly closed before starting the engine.

Start the engine from the operator seat only. Be sure that the transmission is in neutral and the header, separator, and unloader clutches are disengaged.

Be sure that every person is clear of the combine before starting the engine.

Wc1955

FIG. 8 FIG. 9: Always wear the seat belt when the combine is moving. If another person is riding in the instructor seat that person must wear the seat belt. Seat belts must be worn fitted snugly around the hips and not twisted.

Wc1953a

FIG. 9 79027284 A Rev.

01-3

Safety FIG. 10: Never permit any person to be on any part of the combine or the attachments except in the operator seat or the instructor seat when the engine is running.

Do not get on or off the combine while the combine is moving.

Wc1945

FIG. 10 FIG. 11: Prevent contact with electrical power lines.

Always put the grain tank unloader tube in the transport position and lower radio antenna before moving the combine near electrical wires. Contact with electrical power lines can cause electrical shock, very serious injury, or death.

Wc1937

FIG. 11 FIG. 12: Use extra caution and reduce speed when operating on hill sides, near ditches or embankments especially with a full grain tank to prevent an over turn of the combine. Travel speed must be such that the machine has complete control and stability at all times. Shift to a lower gear before going down a steep hill.

Wc1937a

FIG. 12 FIG. 13: Always turn off the engine, shift the transmission to neutral, set parking brake, and remove the start key before leaving the operator seat or before permitting a person to inspect, clean, lubricate, adjust, or repair any part of the combine or the attachments. Unless specifically given instruction different in this manual.

Never leave the operator seat as long as the engine is operating.

Wc1958

FIG. 13 01-4

79027284 A Rev.

Safety FIG. 14: Never work under the header or feeder house, unless the stop is properly engaged on the header lift cylinder, the engine is stopped, the parking brake is set, and the start key is removed from the start switch.

Wc1954

FIG. 14 FIG. 15: Fluid under high pressure can be almost invisible but can go into the skin causing serious injury.

See a doctor immediately if you sustain an injury from escaping fluids. Fluid injected into the skin must be surgically removed within a few hours or gangrene can result.

Wc1938

FIG. 15 FIG. 16: Use a piece of cardboard or wood to search for possible leaks. Never use your hands.

Relieve pressure from the hydraulic and fuel injection systems by lowering raised equipment, shutting off accumulator valve, and turning off the engine before loosening any part of the systems. Tighten all connections securely before applying pressure.

D-5842a

FIG. 16 FIG. 17: The surfaces in and around the engine compartment will be hot if the engine has been running, even for a short time.

Always permit parts that contain hot fluid to cool before handling or disconnecting.

Wc1947

FIG. 17 79027284 A Rev.

01-5

Safety FIG. 18: Do not remove radiator cap if engine is hot.

Wc1951

FIG. 18 FIG. 19: Remove any spilled oil, antifreeze, or fuel immediately from operator ladder and platform and other access areas.

Keep all access areas clean and free of obstructions.

Wc1939

FIG. 19 FIG. 20: Never permit any flame cutting, welding, or arc welding to be done on or near the sound proofing upholstery used in the cab. This material is flame resistant to normal exposure to cigarettes or other smoking material. But will ignite and sustain combustion when exposed to the heat of gas or electrical welding. The build up of chaff and crop debris in the engine compartment, on the engine, and near moving parts is a fire hazard. Check and clean these areas frequently.

Wc1946

FIG. 20 FIG. 21: Always stop the combine engine before fueling.

Do not smoke while fueling.

Wc1959

FIG. 21 01-6

79027284 A Rev.

Safety FIG. 22: Electrical storage batteries give off highly flammable hydrogen gas. Keep smoking material, open flame, or electrical sparks away from the battery. Do not lay tools or other conductive materials on the battery.

Be careful when connecting booster cables to combine batteries. Electrical component damage or battery explosion can result if booster cables are not installed correctly.

Do not charge a frozen battery as the battery can explode. Warm battery to 16 degree C (60 degree F).

WC1950

FIG. 22 FIG. 23: Fluid in electrical storage batteries contains sulfuric acid. Avoid all contact of fluid with eyes, skin, or clothing. If contact does occur, flush off immediately with large amounts of water.

m

WARNING: In order to provide a better view, certain photographs and illustrations in this manual may show an assembly with the shield removed. Do not operate combine unless all shields are in place.

Safety TRAVEL ON PUBLIC ROADS FIG. 68: See your local law enforcement agency for local regulations about the movement of farm equipment on public roads.

•

Use head lights, flashing warning lights, tail lights, and turn signals day and night unless not permitted by local law. Make sure lights, reflectors, and SMV emblem are installed, in good condition, and wiped clean.

•

Check to make sure all combine road lights (especially the amber flashers and red tail lights) are working.

•

Lock brake pedals together with the locking strap so that both front wheel brakes will be applied at the same time.

•

Empty the grain bin.

•

Position unloading auger tube in the folded (transport) position.

•

Remove the header if possible. If the header is to remain on the combine during transport, position header so the operator can see as good as possible.

Make sure the header has enough ground and road clearance.

S-1025

FIG. 68

IMPORTANT: Do not carry the header at a height of more than approximately 610 mm (24 in) off of the ground or road surface.

•

Open the hydraulic accumulator valve before transporting the combine. This will reduce header movement and combine loping when moving on rough roads.

m

CAUTION: Maintain proper tire pressure at all times to make sure of stability during road travel.

•

Measure the overall width and height of the combine.

These measurements are important when transporting along narrow roads and where under passes can be found.

•

Be aware of the other vehicles on the road. Keep well over to your side of the road, and pull over when possible, to let faster vehicles pass.

•

Adjust travel speed to keep control at all times. Never permit combine to coast down hills.

•

Reduce speed of combine by slowly pulling hydrostatic control lever to neutral, before applying the brakes. Do not apply the brakes quickly, especially if the combine is equipped with a large header, since weight movement (during rapid braking) can cause the rear wheels to come off the ground and result in loss of steering control.

•

When taking the combine to a complete stop, slowly move the hydrostatic control lever to the neutral position, and apply the brakes (if necessary).

01-26

79027284 A Rev.

Safety •

Make all turns slowly. The combine is steered by the rear wheels and can loose control if turned quickly at transport speeds. This condition will be seen more when a large header is installed on the combine.

•

Remember steering to the right moves the rear of the combine to the left.

Steering to the left moves the rear of the combine to the right.

•

If the engine is not running, the steering will become manual and be very difficult to handle. Difficult steering also can result in loss of control.

•

Drive component damage can result from towing.

m

CAUTION: Do not tow the combine on a public road.

FIG. 69 FIG. 69: Four functions are done in the overall harvesting operation of a combine. These are: •

Cutting and Feeding

•

Threshing

•

Separating

•

Cleaning

Cutting and Feeding The crop is gathered by a header which is supported by the feeder housing.

The grain header uses a reel to direct the crop into the header auger after the crop is cut by the knife and the header auger moves the crop into the feeder (1).

When a pickup header is used, the crop, already cut and laying in a swath, is lifted by a pickup and fed to the header auger where the retractable fingers move the crop into the feeder.

The feeder elevator transports the crop to the front of the accelerator beater (2) which moves the crop to the rotor inlet area and the rotor (3). The feed beater also guides rocks and other foreign objects into the stone trap (16) located forward and below the beater.

79027284 A Rev.

01-29

General Information Threshing and Separating

Cleaning

The rotor does four functions as the crop moves in a rotary motion from the front to the rear:

The material is moved from the front of the separator return pan onto a short cascade pan (8) which in turn moves the mixture across a fingered comb and into the front of the chaffer sieve.

•

Intake

•

Threshing

•

Separating

•

Discharge

The auger flighting in the intake area starts the crop on a spiral route around the rotor and moves the crop to the threshing area.

Threshing and first separation are done in the threshing zone as a result of the relationship between the rotating cylinder bars and the stationary open grate concave (4).

Contact with the helical guide vanes (5) causes the material to move rearward and in a circular route, letting the material to pass over the concave several times.

The remaining separation occurs in the separating section. Centrifugal force carries the grain and chaff through the grate (6) while the straw moves rearward in the rotor cage. Again, the spiral motion of the crop lets the crop pass over the separating grates several times.

Cylinder bars on the rotating rotor hold the crop against the grates until the crop reaches the end and then paddles bat the material into a discharge chute where the crop is moved to a straw spreader, chopper, or discharged directly to the ground.

The cleaning fan (9) supplies air to keep the chaff in suspension during the cleaning operation in the shoe.

The air blast passing through the turning adjustable chaffer (10) separates and blows the chaff out of the combine. The grain and tailings drop through to the cleaning sieve.

The adjustable cleaning sieve (11) does the final cleaning. The clean grain falls through the sieve into the clean grain auger. The tailings, chaff, and other material continue to the end of the sieve and into the return auger (12) to be threshed again.

The grain elevator paddle chain moves the clean grain from the clean grain auger (13) to the grain tank filling auger and into the grain tank (14). The return elevator carries the tailings back to the rotor intake for threshing and separating.

The grain in the grain tank is unloaded into a truck or trailer through the turret type unloading auger (15).

Grain, chaff, and any heads not threshed which went through the separator grates are carried to the cleaning shoe by the separator return pan (7).

General Information TIRES AND WHEELS Tire Pressure Tire pressures for both front and rear tires must be checked every 50 hours of operation or weekly. See the Specifications section for the correct tire pressures.

NOTE: The combine is sent from the factory with tires over inflated. Pressures must be checked and adjusted before operating the combine in the field.

NOTE: Combines can be sent with special 16.9 x 34 shipping tires and wheels for clearance requirements. Do not install the header, or move the base combine on these shipping tires more than necessary to unload the combine from the truck.

After the combine is unloaded, replace the shipping tires and wheels with the operating tires and wheels ordered with the combine.

Removing Wheel from Combine and Removing Tire.

•

Park the combine on level ground with the brakes locked and the combine blocked securely during wheel removal.

•

When removing a drive wheel, secure the wheel with a tire dolly or hoist before removing the wheel retaining nuts or capscrews.

•

Do not unseat the beads of an inflated tire. Deflate the tire completely before servicing.

•

Do not inflate a tire that has been run flat or very under inflated without removing and checking for tire and rim damage.

•

Do not remove or install the tire on the rim without the proper tools. Do not hit the tire or rim with a hammer.

General Information Tire Mounting Precaution

Reason for Precaution

Never mount a damaged tire.

The tire structure can be weak to the point at which the tire will not hold up to the stresses of inflation and operation.

The tire will fail with explosive force.

Always inspect the well, bead seat areas, flanges, and rim to be sure the surfaces are clean and smooth. Remove any rust, corrosion, or old rubber with a chisel or wire brush.

Failure to provide clean, smooth rim surfaces can cause the bead to catch on well of rim and break with explosive force when inflated.

Apply lubricant (thin vegetable oil, soap solution, or approved tire mounting rubber lubricant) to the inside and outside surfaces of both beads. Apply lubricant to flanges and bead seat areas of the rim.

Failure to provide proper lubricant can cause the bead to catch on the edge of the bead seat and break with explosive force when inflated. Lubrication is required for proper position of the tube for the tube to extend properly.

Check to be sure the tire is centered on the rim before inflating.

Failure to center the tire on the rim can cause the bead to catch on the edge of the bead seat and break with explosive force when inflated.

Always use an extension hose with a clip on chuck and extension gauge when inflating.

Extension equipment permits the operator to stand clear of the assembly during inflation. If the assembly fails for any reason, the operator will be away from the explosive force.

Never use pressure above 241 kPa (35 psi) (283 kPa (41 psi) for 800/65 R32 tires) to seat the tire beads. If the beads have not seated by the time the pressure reaches this pressure, remove the valve core, deflate the assembly, completely replace the valve core, position the tire on the rim, lubricate the tire beads, and the rim bead seats. Inflate the tire.

Use of inflation pressure above 241 kPa (35 psi) (283 kPa (41 psi) for 800/65 R32 tires) to seat the beads can cause the assembly to fail with explosive force. Be sure the rim diameter is exactly the same tire diameter being used.

General Information Wheel Installation The discs are offset in the wheel rim.

FIG. 115: To set the front wheels out in field position, mount the wheel with larger offset to the outside.

To set the front wheels in for field position, locate with smaller offset to the outside.

CAUTION: When removing wheels, lift Combine using a jack able to support the weight of the combine, and block securely using solid blocks or steel supports. DO NOT use concrete blocks to support combine.

D-5586a

FIG. 115 FIG. 116: The drive wheels can be reversed for a wider wheel tread if necessary. When reversing the wheels make sure that there is enough clearance between the valve stem and the final drive housing to prevent the valve stems from being damaged.

If there is not enough clearance, or operating in conditions where the ground is too soft, remove the two plugs that were sent in the Instruction Group envelope under the instructor seat. Inflate a tire slightly over the normal pressure and remove the valve stem. Quickly insert and tighten the plug (1) instead of the stem. Repeat the procedure on the other wheel.

79027284 A Rev.

General Information Maintenance of Tires To reduce the amount of wear, and extend the life of the tires, the tires must be kept at the correct pressures and checked at regular intervals.

When the combine is going to be out of use for an extended period, or is being stored, block both sides of the axles to take weight off the tires.

If oils or solvents are spilled on a tire, clean immediately.

Never park or stop the combine with tires standing in an area of oil.

If possible, park the combine where the tires will be kept from direct sun. This is important if the combine is parked for extended periods, or is being stored.

If mounting tubeless tires, make sure the flange and bead area of the tire and rim are free from dirt, rust, or old rubber. The rim must be smooth and clean. Any areas of rust must be cleaned and painted with a rust preventing type paint.

m

WARNING: Failure to follow correct procedures when mounting a tire on a wheel or rim can cause tire to EXPLODE which can result in serious injury or death.

DO NOT mount a tire unless you have the proper equipment and experience to complete the job. A qualified tire repair service has the proper equipment.

Never exceed 241 kPa (35 psi) or the maximum inflation pressures specified by tire manufacturers for mounting tires.

Inflation beyond this maximum pressure can break the bead, or even the rim, with dangerous explosive force. If both beads are not seated when maximum recommended pressure is reached, deflate, reposition tire, lubricate bead and inflate tire.

General Information DRIVE BELTS Banded Drive Belt FIG. 117: A banded drive belt is made of two or more V-belts (of a standard cross section size) banded together at the top with a tie band (1). The separate V-belts and the tie band are vulcanized together to form a multiple strand banded belt.

1

The cross section and spacing of the separate strands are such that the banded belt operates on standard sheaves.

The tie band clears the top of the sheaves so that each belt strand has full wedging capacity in the sheave grooves, just as a single belt. The banded belt operates at the same tension as separate matched belts on an regular multiple strand V-belt drive.

Most V-belt drives operate without any problem, requiring only regular maintenance. There are times where forces acting on the drive can cause separate belts to whip, turn over, or come off the sheaves. The banded belt was designed to correct these belt stability problems which are most frequently caused by intermittent or shock loading of the drive.

D-6150

FIG. 117

Banded belts have standard dimensions and cross section sizes and are made to order, with the number of strands being determined by the power needs of the drive. Spacing between the strands of the belt are the same as the Rubber Manufacturers Association (RMA) standard spacing for multiple groove sheaves.

01-60

79027284 A Rev.

General Information Maintenance of Belts FIG. 118: Cross sections of some of the belts used on the combine are shown.

A drive inspection must be done every one to two weeks.

Check belts frequently for excessive wear, tearing, breaking, increasing, and unraveling.

Belt tensions are controlled with spring loaded idlers on most drives on the combine. Over tightening puts too much strain on the belt and too much loading on the shafts and bearings.

Look and listen for any not normal vibration or sound while watching the drive in operation. A drive kept in good condition will operate smoothly with little noise.

Inspect guards for looseness or damage. Keep all guards free from debris, dust, or grime deposit on either the inside or the outside of the guard. Deposits of material on guards operate as insulation causing drives to run hotter.

Belts that are running hot, running in a hot environment, or from slipping will harden and form cracks from the bottom of the belt up.

An internal temperature increase of 10 degrees C (18 degrees F) can cut belt life in half.

Inspect for oil or grease leaking on the drive. This can indicate over - lubricated bearings or a fluid leak. If this material gets on rubber belts, the belts can increase in size and become distorted, causing an early belt failure.

Belts must be replaced if there are signs of cracking, fraying, or not normal wear.

Engage the parking brake.

Disconnect the battery at battery switch.

Raise or remove shields or guards and locate the guards away from the drive so that the guards do not cause problems with working on the drive.

Loosen tensioner until the belt is slack and can be removed without prying. Never pry off a belt, as the sheave can be damaged. Prying off belts also adds risk of injury.

J312506

FIG. 119

Inspect the old belt for any not normal wear. Excessive or not normal wear can indicate problems with the drive or past maintenance procedures. Refer to the Belt Problem and Wear Guide.

Inspect the sheaves for not normal or excessive wear, damage, distortion, and pitting. If surfaces show pitting or excessive wear, the sheave must be replaced.

Check the sheaves for deposits of dirt and dust in the bottom of the grooves. Clean sheaves with a damp cloth.

Do not sand or scrape the grooves to remove debris.

Installation Check the sheave alignment. For long belt life the sheaves must be aligned properly.

FIG. 121 FIG. 122: When replacing a belt, never force a belt over the rim of a pulley. Do not pry or use force to install the belt (A). This can break the cords in the belt. Loosen all the tensioners before installing the new belt. If the belt still can not be easily installed, run the belt over the rim while rotating the pulley (B).

A

Tension the belts making sure the belts are at the correct tension. More belts are damaged by not enough tension than by too much tension. But, do not over tension the belt as this damages the belt tensile members and puts an additional load on the shafts and bearings.

Rotate the belt drive three revolutions. Check the belt tension and adjust as necessary.

B

Check the drive alignment and adjust as necessary.

Install the guards or shields.

Start the drive, looking and listening for any not normal noise or vibration. If possible, stop the drive and check the bearings and sheaves for excessive heat. If the bearings and sheaves are too hot the belt tension can be too high or the bearings are not properly lubricated or failing.

Temperature can be checked with an infrared pyrometer.

General Information Belt Sheave Alignment FIG. 123: Check the sheave and shaft alignment.

Running the belts with the sheaves out of alignment will cause severe side wear.

2

Not aligned belt drives will be noisier than properly aligned drives since interference is at the belts enter point into the sheave.

To check the alignment use a long straight edge (1) made of wood, metal, or any rigid material. Line the straight edge along the outside face of both sheaves. If the drive is properly aligned, the straight edge will contact each sheave evenly. The straight edge must touch the two outer edges of each sheave for a total of four points of contact.

B

C

1

Shafts not in alignment (C) will show up as a gap (2) between the outside face of the sheave and the straight edge.

Check for tilting or shafts not aligned by using a bubble level. For proper alignment, the bubble must be in the same position as measured on each shaft.

Not aligned correctly Parallel (A).

Not aligned correctly Angular (B).

Rotate the drive and look for excessive sheave movement. If excessive sheave movement is seen inspect the sheave and shaft. If no problem can be seen, remove and install the sheave. Not correctly mounted sheaves or out of round sheaves are some times the root of vibration or more severe problems. A dial indicator can be used to measure side to side sheave movement or diameter vibration by holding the dial indicator up to the sheave sidewall or top of the belt inside the pulley groove.

A D-5595c

FIG. 123

IMPORTANT: Always turn off the machine before using the dial indicator. Rotate the drive by hand to make your measurements.

Belt Run In Procedure A run in procedure is needed for all belt drives so that the best belt life can be reached.

A run in procedure is made of starting the drive and operating the drive under full load for up to 24 hours. After the belts have run-in, stop the drive and check the belt tension.

Running the belts under full load for an extended period of time will seat the belts into the sheave grooves.

Belt tension will drop after the first run-in and seating procedure. This is normal. Adjust the belt tension as necessary.

Since tension in belts will drop after the first run-in and seating procedure, failure to check and tension the belt will result in low belt tension and belt slippage. This slippage will result in early belt failure.

General Information Belt Troubleshooting When troubleshooting a belt drive problem, stand back and watch the drive while the drive is in operation and when the drive is not. Is there a warm rubber smell? Is the belt moving around the drive in a normal way? Are there chirping, squealing, or grinding noises? Is there a deposit of dust or debris under the drive which will cause problems with the belts?

When the belt drive makes excessive noise, the belt is frequently blamed. To find the problem spray the belt with soapy water while the drive is running. If the noise goes away, or decreases, the belt is part of the problem. If the noise is still present, the problem can be caused by other drive components.

NOTE: Do not use belt conditioner or dressing on the belts.

Not correctly tightened belt drives can make noise.

General Information ROLLER CHAINS Inspection of Drive Chains and Sprockets Experience will determine how frequently drive chains will need to be inspected and serviced. Make a regular schedule and follow the schedule.

With new chains and sprockets some adjustment of chain tension can be looked for during the first run-in period.

Inspect the chains and sprockets for the following: 1. Wear of the chain link side plates.

2. Wear on the sides of the sprocket teeth.

3. Alignment of sprockets, idlers, and shafts.

4. Chain elongation.

5. Wear on the working faces of the sprocket teeth.

Check for interference between the drive and other parts of the equipment. If there is any interference, correct immediately. Interference can cause not normal and damaging wear on the chain and interference part. If the edges of the chain link plates hit against a rigid part, link plate will become weak because of strain and a chain failure can result.

Check for and remove any deposit of debris or foreign material between the chain and sprockets. A small amount of material in the sprocket roll seat can cause tensile loads large enough to break the chain if forced through the drive.

Inspect the chain for cracks, broken, or parts with a distortion. If any of these conditions are found, replace the complete chain. Even if parts of the chain look in good condition, the complete chain has been damaged.

79027284 A Rev.

01-79

General Information Drive Chain Adjustment and Tightening Proper adjustment and tightening is necessary for long drive chain service life.

Over tightening causes drive chains to elongate and puts additional loading on sprockets, shafts, and bearings.

Loose drive chains will climb on the sprocket teeth and cause excessive wear.

FIG. 124: To check drive chain tension, turn the driver sprocket in a direction that is opposite to the normal direction of rotation (to remove all the slack from the idler sprocket strand of the chain). Measure the slack at the middle point of the longest drive strand as shown.

As a general rule: •

Horizontal and inclined drive chains must be adjusted to have approximately 20 mm of slack per meter of distance between the center of the driver and driven shaft (0.25 inches of slack per foot of distance between the center of the driver and driven shaft) or approximately 2% of the distance between the center of the driver and the driven shaft.

•

Vertical drive chains that see shock loads or changes of rotation must be adjusted to have approximately 10 mm of slack per meter of distance between the center of the driver and the center of the driven shaft (0.125 inches of slack per foot of distance between the center of both the driver and the driven shaft) or approximately 1% of the distance between the center of the driver and the center of the driven shaft.

79027284 A Rev.

General Information Drive Chain Sprocket and Idler Alignment If there is wear on the inside surface of the chain roller link plates, the sprockets are not aligned. Make sure that: FIG. 125: The shafts (that the driver and driven sprockets are mounted on) are in the same location (level with each other).

Check for tilting or shafts not in alignment by using a bubble level. For proper alignment, the bubble must be in the same position as measured on each shaft.

Rotate the drive and look for excessive movement. If movement is shown inspect the sprocket and shaft. If there is no problem shown, remove and install sprocket.

Not correctly mounted sprockets or out of round sprockets are from time to time the root of vibration or more severe problems. A dial indicator can be used to measure side to side sprocket movement or diameter vibration by holding the dial indicator up to the sprocket sidewall.

IMPORTANT: Always turn off the machine before using the dial indicator. Rotate the drive by hand to make your measurements.

D-6153

FIG. 125

FIG. 126: The shafts (that the driver and driven sprockets are mounted on) are parallel to each other.

D-6154

FIG. 126 FIG. 127: The driver and driven sprockets are in line (not offset).

To check the alignment use a long straight edge (1) made of wood, metal, or any rigid material. Line the straight edge along the outside face of both sprockets. If the drive is properly aligned, the straight edge will contact each sprocket evenly. The straight edge must touch the two outer edges of each sprocket for a total of four points of contact.

1

Shafts not aligned will show up as a gap between the outside face of the sprocket and the straight edge.

FIG. 127

79027284 A Rev.

01-81

General Information FIG. 128: The idler and adjusting sprockets are in alignment with the driver and driven sprockets.

Bad alignment, especially with multiple strand chains results in not equal loading across the width of the chain and can cause an early chain failure.

D-6157

FIG. 128

Drive Chain Elongation and Sprocket Wear Drive chain wear occurs on the inside of the chain in the load bearing areas between the chain outer link hardened pins and the chain inner link bushing surfaces. This wear causes chain elongation which is referred to as chain stretch.

This wear is not seen on the outside of the chain and cannot be measured with the chain under tension. To measure chain elongation, remove the chain and select a 305 mm (1 ft) section of chain. Push the selected section of chain tightly together and measure the distance between the link pins. Then pull the same selected section of chain and measure the distance between the same link pins. If the movement (elongation) is more than 10 mm per meter (0.125 inches per foot), the chain is worn out and must be replaced.

When wear of this amount or more is seen, the hardened surfaces on the link pins are worn through. The chain is worn out, and making frequent adjustments will be necessary.

Gradual increase in chain slack is the result of normal chain wear. A sudden increase in chain slack indicates one or more of the following problems: 1. Not enough lubrication or failure of the lubricant.

2. Excessive over loading or shock loading of the chain drive.

3. Loose bearing mounting hardware or a failed drive.

4. Loose idler sprockets, chain guide blocks, or failed idler sprocket bearings.

General Information Normal Tooth Wear FIG. 129: Normal Tooth Wear.

Worn sprockets must not be used with new roller chain.

D-6161

FIG. 129

Not Normal Tooth Wear FIG. 130: Chain tension that is not correct can cause not normal wear on the outer tips of the sprocket teeth. Not enough chain and sprocket lubrication can cause not normal wear of the sprocket teeth.

Check for roughness or binding when the chain engages or disengages from the sprocket. Inspect the sprocket teeth for reduced tooth section and curved tooth tips.

If these conditions are present, the sprocket teeth are excessively worn and the sprocket must be replaced. Do not run new chain on worn sprockets as this will cause the new chain to wear rapidly.

D-6162

FIG. 130

Worn Chain on New Sprockets FIG. 131: A worn or elongated drive chain must never be used with new sprockets since the chain no longer fits the sprocket teeth properly. The pitch of the chain is larger than the pitch of the sprocket teeth. A worn or elongated drive chain rides high on the outer tips of the sprocket teeth, causing rapid wear on the outer tips of the sprocket teeth.

D-6160

FIG. 131

79027284 A Rev.

01-83

General Information Drive Chain Service Tips FIG. 132: To extend drive chain service life follow these rules: •

Chains must be removed from the combine for cleaning and lubrication at the end of every season.

In addition, drive chains must be lubricated daily (except when operating in dusty or sandy field conditions).

•

Periodically, check the alignment of all sprockets and idlers. A sprocket not in alignment will wear on the sides of the sprocket teeth or on the inside of the chain inner (roller) links.

•

To remove a chain, turn the drive until the connecting link is fully engaged on one of the sprockets (to relieve the tension on the connecting link pins), then remove the connecting link pins and lift the chain off the sprockets.

•

Never insert a new link in a chain that has been elongated by wear. The pitch of the new link will be shorter than the pitch of the worn links. The shock each time the new link engages a sprocket will soon destroy the chain.

•

Do not install a new chain on worn sprockets.

Operation under such conditions will do more damage to a new chain than many hours of normal use.

•

Do not install a worn or elongated chain on new sprockets. A worn or elongated chain will ride high on the outer tips of the sprocket teeth causing rapid wear of the new sprockets.

•

As a drive chain wears and extends, always remove links to make sure the chain length and tension are correct.

General Information Chain Replacement Pin Removal If chain is of cotter pin type construction, remove the cotter pins.

If chain is of riveted type construction, grind the pin heads off so the pin ends are flush with the link plate. Drive pins out of the link plate.

Installation Check all adjustments, alignment, and make sure all setscrews, bolts, and nuts are tight on the chain drive.

Fit the chain around both sprockets and put the free ends together on one sprocket for connection. The sprocket teeth will locate the chain end links. Install the connecting link, connecting link cover plate, and the spring clip or cotter pins. On larger pitch chains or heavy multiple strand chains, lock the sprockets for this operation. When press fit cover plates are used, be careful not to drive the plate on so far as to grip the roller links. Stiff joints can result if this is done.

On drives with long spans, support the chain with a plank or bar as the connection is made.

FIG. 133: When using spring clip connectors, always install the spring clip (1) with the open end of the clip trailing in the direction of chain travel to prevent removal or loss of the spring clip.

General Information Cleaning and Lubricating Chains Roller chain is made of a series of connecting moving metallic bearings, which must be properly lubricated to get the maximum service life out of the chain. Many slow speed drives operate with little or no lubrication beyond the first factory lubrication. But proper lubrication will extend the life of every chain drive. The chain drive requires lubrication for six purposes.

1. To reduce wear of the pin bushing joint.

2. To cushion shock loads 3. To remove heat generated.

4. To flush away foreign materials.

5. To lubricate chain sprocket contact surfaces.

6. To retard rust or corrosion.

Lubricate chains with AGCO chain and cable lubricant or light engine oil at least once every ten hours of operating time. Apply the lubricant when the chain is warm, then let the extra oil drain off before operating the combine.

m

WARNING: Never lubricate chains with the combine mechanism in operation.

Once every season, or when the chains show signs of becoming stiff, remove the chains from the combine and service as follows: •

Clean in solvent to remove dirt.

•

Permit the chain to soak as long as possible in engine oil, over night if possible.

•

Remove the chain from the oil and put the chain in position to permit extra oil to drain off.

•

Wipe the chain with a clean cloth.

IMPORTANT: The chain must be permitted to drain completely.

NOTE: The clean grain tailings elevator and the feed house conveyor chains do not have to be lubricated.

The seal rings form a reservoir of lubrication between the pin and bushing. Lubricating the chain periodically can prevent surface rust. If the chain requires cleaning, use kerosene applied with a cloth. Do not apply kerosene directly or soak chain in kerosene.

IMPORTANT: The chain must not come in contact with solvents such as gasoline, benzene, acetone, or other corrosive materials as this will damage the O-rings.

01-86

79027284 A Rev.

General Information Drive Chain Lubrication Drive chain service life will vary according to the method the chain is lubricated. A properly lubricated chain will last 100 to 200 times longer than the same chain which is poorly lubricated and not kept in good condition.

Lubrication of the chain pins and inner link bushing surfaces which contact each other while the chain is under full load are most important. Lubrication to a smaller degree is also required between the chain rollers and inner link bushing surfaces.

Oil must be applied to the upper edges of the chain link side plates on the slack chain strand before the chain engages a sprocket. Since access of oil to chain pins and bushings is only possible through the clearances between the link side plates when the chain is slack.

If oil is applied only to the chain rollers the oil can not reach the chain link side plate pins and bushings, and can not retard chain wear.

The elongation of roller chains results from wear between the pins and bushings only. Roller wear does not cause or add to the extending of roller chains.

Drive Chain Lubricants Lubrication specifications are met by the use of a good grade of clean engine oil without detergents.

Detergent oils are not required but oils with anti-foam, anti-rust, or film strength additives can be beneficial.

The proper lubricant viscosity for many operating temperatures are shown in the chart below.

Ambient Operating Temperatures

Recommended Lubricant

SAE 50

NOTE: Heavy oils and greases are too stiff to enter the chain joints and must not be used.

With proper lubrication, a separating wedge of lubrication is formed between the pins and bushings in the chain joints much like that formed in journal bearings.

The viscosity of the lubricant changes the lubricants film strength, and capacity to keep moving parts separate.

The highest viscosity oil which will flow between the chain link plates and fill the pin bushing areas will provide the best wear life. This is needed to reduce metal to metal contact. If the lubricant is supplied with enough volume, the lubricant also cools and cushions shock loads.

79027284 A Rev.

01-87

General Information Good Drive Chain Lubrication Connector link pins, on removal from a properly lubricated drive chain, will have a high luster polish and will not be changed in color.

Drive chains which are operated without proper lubrication will have a reddish brown oxide in the joints.

On removal, the connector link pins will be changed in color, rough, with grooves, or damaged.

When operating in dust containing excessive amounts of damaging particles (sandy field conditions), the chain must not be lubricated on the outside. The oil will pick up damaging particles that forms a grinding compound with lubricant (similar to valve lapping compound) which causes early wear of both the sprockets and the drive chain.

Under severe conditions, the chain must be removed every 50 hours of operation cleaned and lubricated, following the procedure shown below: 1. Remove the chain from the sprockets.

2. Wash the chain in cleaning solvent (varsol or kerosene). If the chain is gummed, soak the chain for several hours in the cleaning solvent, and then wash the chain in clean fluid.

3. Using clean and dry compressed air, blow the chain dry or wipe the chain dry with a clean towel or cloth.

4. Inspect the chain for wear and corrosion.

5. Soak the chain in engine oil to internally lubricate the pins, bushings, and rollers.

6. Position the chain in a vertical position and permit the extra lubricant to drain off.

7. Wipe the chain dry with a clean shop towel or cloth.

8. While the chain is off the sprockets, clean the sprockets with cleaning solvent (varsol or kerosene), and inspect the chain for wear and corrosion.

9. Check the driver, driven, and idler sprocket alignment and make corrections if found necessary.

10. Install the drive chain and properly adjust the chain tension.

General Information ENGINE FUEL SYSTEM Fueling the Combine FIG. 141: When fueling the Combine (1) the following precautions must be taken: Fuel is highly flammable and caution must be taken when fueling the combine.

1

Always stop the engine when fueling the combine.

Do not smoke or have an open flame near the fuel.

Clean any surfaces where fuel was spilled to prevent chaff deposit and possible fire hazards.

Do not use containers and funnels to move fuel, as the containers are difficult to keep clean.

Fill the combine fuel tank following operation each day to prevent condensation.

m

J127251

FIG. 141

CAUTION: Do not smoke, light matches, or lighters when filling fuel tank.

Important Storage and Handling Precautions To be sure the fuel is always clean and free from water or foreign material, the following precautions must be taken: Never leave fuel stored in an open container as water and dust will make the fuel dirty.

Store fuel in tanks equipped with a water trap. Drain water trap frequently.

Never store fuel in a galvanized container. A chemical reaction can occur between the fuel and the galvanized coating, and contaminate the fuel.

If necessary to store fuel in drums, make sure the drums are free of water, gasoline, or sediment.

Keep drums under cover away from direct sun light and rain. Keep plugs in location and tight.

Do not move the tank or drum, if possible.

Do not use the last several gallons of fuel from the storage tank since the fuel can contain water and sediment.

Fuel Conditioners Good quality fuels contain enough additives to clean and protect your combine engine. Fuel conditioners, when used according to directions, can help fuels when stored for extended periods of time. Conditioners also help to remove moisture, varnish, and deposits from the fuel system. When added to the fuel in extremely cold weather, fuel conditioners will help prevent fuel from gelling and separation of wax particles. Gelling and separation of diesel fuel can result in filter plugging, poor performance, and difficult starting.

NOTE: Use AGCO diesel fuel conditioner to protect against wax, gum deposits, and water contamination when storing fuel for three months or more.

General Information Fuel Specifications Diesel fuel does two major functions in a Diesel Engine.

•

Diesel fuel supplies all the energy for the engine.

•

Diesel fuel cools and lubricates the precision parts of the fuel injection pump and injectors.

Use grade Number 2 diesel fuel as shown in ASTM D 975, when temperatures are above the freezing point.

The use of other fuels will result in reduced engine performance and higher fuel consumption. Number 1 diesel can be used when temperatures are below 0 degrees C (32 degrees F).

Do not use fuels that contain more than 0.5% (by weight) sulfur. High sulfur content can result in excessive corrosion in the injection equipment and combustion system.

The cetane number of a diesel fuel is a rating similar to the octane numbers used to rate the combustion in gasoline. Never use a fuel with a cetane number below 40. When operating at higher elevations, use a higher cetane fuel.

Diesel engines will run on different types of diesel fuel.

Some fuels will provide better performance, higher efficiency, be more problem free, and lower maintenance costs than other fuels. Fuel must be selected on overall operating costs, and not on the price per gallon of the fuel.

Select a reputable fuel supplier and buy only clean diesel fuel that meets the required specifications.

Fuel Vent Breather FIG. 142: The fuel vent breather (1) is located in the grain bin, under the lip, at the left-hand front corner of the grain bin.

The fuel vent breather does not have to be serviced frequently, but must be checked once a year. The fuel vent breather can be removed and cleaned completely and installed. Make sure the breather is under the lip of the grain bin.

General Information Fuel Filter and Water Separator FIG. 143: The combine is equipped with two fuel filters.

One primary canister type fuel filter (1) with water trap is located on the right-hand side of combine in front of clean grain elevator. Drain water and sediment from the separator every 50 hours. Shut off the engine and open drain valve (2) permit fluid to drain into a suitable container until clear fuel can be seen, close drain valve.

1

2 K910878

FIG. 143 FIG. 144: One canister (1) is in the supply line near the right-hand side of the fuel tank.

The canister filter and water separator on the engine must be changed every 500 hours of operation or once a season.

Before servicing the filters close fuel shut off valve below fuel tank and completely clean outside of filter assembly.

DO NOT fill the new filter with fuel. Lubricate seal with clean engine oil and install filter. When fitting the spin on element, tighten by hand until seal just touches filter head and then tighten three-quarters of a turn. Each time the filter is changed bleed the air from the system.

General Information Bleeding the Fuel System Bleeding air is normally not required unless an excessive amount of air has entered the system.

NOTE: If the fuel system requires external bleeding see the Engine Operation and Maintenance manual for details.

m

CAUTION: Engine can start when air is vented from high pressure lines. Stay clear of moving engine parts.

IMPORTANT: DO NOT engage starter for more than 15 seconds at a time. Wait 30 seconds between engagements.

m

CAUTION: DO NOT bleed a hot engine as this could cause fuel to spill onto hot exhaust manifold creating the danger of fire.

m

DANGER: Escaping fuel under high pressure can have sufficient force to penetrate the skin causing serious injury.

General Information ENGINE COOLING SYSTEM Coolant Type Use only low-silicate permanent antifreeze. The silicate content must not be higher than 1%. A 50/50 mixture of antifreeze and water can be used in the combine year round.

IMPORTANT: Do not use organic acid type antifreeze.

Coolant Change Period Cooling system must be flushed after 1000 hours of operation. Fill system with 50% clean water and 50% low silicate diesel antifreeze.

Add coolant conditioner to coolant mix. See your Engine Operation and Maintenance manual for the correct amount of coolant conditioner.

IMPORTANT: Do not use organic acid type antifreeze.

Engine Cooling System Coolant The cooling system is factory filled with a permanent antifreeze and water mixture to protect engine to temperatures of -34 degrees C (-30 degrees F).

Every 10 hours of operation or daily, clean engine rotary screen condenser, hydraulic oil cooler and radiator with compressed air.

Coolant is made for year round use with a maximum 1000 hours service life. If water is to be used during summer months, an approved type of rust inhibitor must be added to the water.

NOTE: Use only low-silicate type diesel engine antifreeze (less than 0.1 percent of silicate) in the cooling system. (DO NOT use organic acid type antifreeze.)

Coolant System Monitoring Temperature Gauge - The analog display gauge and digital display, located on the electronic instrument panel, indicates temperature of coolant in the engine.

Monitor Warnings When the coolant temperature is above 104 degrees C (220 degrees F), the LED on the electronic instrument panel will flash while the audible alarm sounds for five seconds, after which the warning light continues flashing.

Once the temperature switch opens again, the alarm stops, and the system resets.

Coolant Level If coolant level becomes too low in the radiator, an alarm sounds for five seconds and a red light will flash. The light will flash until the condition is corrected.

NOTE: Determine cause of coolant loss and fill cooling system before operating combine.

79027284 A Rev.

01-103

General Information Checking Coolant Level Check coolant level every 10 hours of operation or daily.

FIG. 145: The engine coolant system has a coolant recovery system and an overflow tank (1) located at the rear right-hand corner of the engine compartment.

1

j127036

FIG. 145 FIG. 146: Check the overflow tank daily to make sure coolant reaches the cold line (1) on the tank. Add coolant up to the cold line when engine is cold.

IMPORTANT: Use a 50/50 mixture of water and antifreeze. DO NOT use 100% antifreeze to top off cooling system.

NOTE: Coolant in the bottom of the overflow tank when engine is cold indicates the radiator is full. A decrease in coolant level over time indicates a loss of coolant. An increase indicates air being pulled into the coolant system.

If coolant loss or increase is found, find any leaks and fill the system.

1

j127038

FIG. 146

Radiator FIG. 147: The radiator is pressurized to 97 kPa (14 psi).

To keep this pressure, the filler cap (1) must fit tightly and be installed securely. If cap is replaced for any reason, always use a cap that permits the coolant recovery system to operate properly. Coolant must be able to enter radiator from the overflow tank.

m

CAUTION: DO NOT remove radiator cap if engine is hot. Allow engine to cool, loosen cap to first notch to let pressure escape, then remove cap.

IMPORTANT: Never add cold water or antifreeze to an over heated engine when the coolant level is low.

The introduction of cold liquid will cause sudden contraction of over heated metal, which can result in cracks to or fracture of the cylinder head or block.

General Information Thermostat The thermostat is fitted in the coolant outlet on the engine.

When coolant is cold, the coolant is sent from the cylinder head through a bypass, to the water pump and does not pass through the radiator. As coolant warms up, thermostat opens permitting coolant to flow to radiator as well as blocking the bypass passage to the water pump.

IMPORTANT: DO NOT operate the engine with thermostat removed. The thermostat is necessary for proper distribution and efficient engine performance. Without the thermostat, the coolant can move and bypass the radiator, causing engine to over heat. A bad thermostat cannot be repaired. The thermostat must be replaced.

Draining System FIG. 148: A drain valve (1) and hose are supplied to drain engine block and radiator. This is located inside the rotary screen shroud at the base of the radiator. For complete system draining open the heater control valve in the cab and valves on the heater hose inlet and outlet hoses at the engine.

1

Park combine on level surface when draining cooling system to make sure the coolant is completely removed.

Remove radiator cap when draining system and put cap on the operator seat as a warning that the engine contains no coolant.

If coolant is changed, new coolant conditioner must be added to replace the anti-corrosion additives in the system.

L602682

FIG. 148

Filling System FIG. 149: Close drain valve at bottom of radiator. Fill system slowly through the radiator pressure cap opening (1) with the recommended coolant until the radiator is full.

IMPORTANT: When filling cooling system, open heater hose valves on engine and open heater control valve located in cab to make sure all air is removed from cooling system. The thermostat housing is vented to the top tank on the radiator through a vent hose to make sure air is removed from the head during the first fill or after draining.

1

Start engine and run until engine reaches operating temperature to remove any air contained in the system.

Shut off the engine and permit the engine to cool. Add any additional coolant as needed to keep the correct level of coolant in radiator. Install the radiator pressure cap and add coolant to the over flow tank to the level mark.

L601578

FIG. 149

NOTE: Coolant conditioner must be added to the coolant. See Engine Operation and Maintenance manual for correct coolant conditioner mix.

General Information ENGINE AIR CLEANER FIG. 150: The engine air cleaner (1), at the right rear side of the combine, filters air pulled into the engine.

IMPORTANT: Do not run the engine without the internal elements installed. Rapid engine wear will occur if dust and dirt is permitted to enter the engine.

1

j127094

FIG. 150

Outer Filter Element FIG. 151: The outer filter element (1) must be cleaned when the yellow LED air filter restriction indicator on the EIP flashes.

1

IMPORTANT: The element must be cleaned as soon as possible after light comes on.

Replace element every 500 hours of operation or once a season or after six cleanings.

Never service the air filter while the engine is running.

To prevent delays, a extra element be carried for immediate replacement. Store the extra element in the original container.

Check the engine air filter hose connections for tightness every 50 hours of operation or weekly.

j127101

FIG. 151

Cleaning Outer Element The outer element (not the inner element) can be cleaned as follows: IMPORTANT: Do not use gasoline, fuel oil, or other solvents to clean element. Also do not hit element to remove dirt.

Dust filled element - If dust is the main contaminant, direct dry, clean air up and down the inside of the element.

Pressure must not be higher than 690 kPa (100 psi) and the nozzle must be kept at least 25 mm (1.0 in) away from the element.

Soot filled element - If carbon is the main contaminant, use both air and washing to clean the element.

Use compressed air or a water hose to remove loose dirt.

Air pressure must not be higher than 690 kPa (100 psi), water pressure must not be higher than 276 kPa (40 psi).

To wash, use filter cleaner and prepare solution as shown on container. A low sudsing detergent can also be used.

Soak the element for a minimum of 15 minutes (maximum 24 hours), moving the element in the solution to help remove dirt.

01-106

79027284 A Rev.

General Information Remove from the solution and flush the element from both sides with a low pressure flow of water to remove all of the foam and dirt. Continue this operation until the water runs clean when passing through the element.

Dry element before using. Warm air or a fan can be used to aid drying. Air temperature must be less than 82 degrees C (180 degrees F). Do not use a light bulb as this can burn the filter element.

Inspect the element for holes and tears by looking through the element toward a light. Leaks are indicated by thin areas, pin holes, or slight breaks.

Inner Filter Element FIG. 152: DO NOT remove inner element (1) unless yellow warning indicator light remains flashing AFTER outer element has been cleaned. If this occurs, the inner element must be replaced.

General Information HYDRAULICS The main hydraulic system and the hydrostatic systems share a common oil supply, filter unit, and cooling core.

The hydraulic fluids must meet the needs of the components in the system.

See the Specifications sections for the correct hydraulic fluid.

Automatic transmission fluids must not be used because of automatic transmission fluids lower viscosities in high pressure systems.

m

WARNING: Lower header or feeder to the ground. Stop combine engine and remove start key before beginning any lubrication or maintenance function.

Checking Oil Level FIG. 153: Check oil every 10 hours or daily, with the combine parked on level ground. With the reel and header down. If not, the reading will not be correct. The oil level must be between the levels shown on the label (1) on the reservoir.

2

If oil is added to the level mark when the header is raised (cylinders extended) the reservoir will over flow when the header is lowered (cylinders retracted).

1

Check the oil level when the oil is cold. Hot oil will raise the level in the reservoir 20 mm (0.75 in). Change the breather element (2) after the first 50 hours then every season following.

General Information HYDROSTATIC DRIVES - 660 General Information The rotor and propulsion pumps are mounted in tandem and are driven from the rear of the engine with a 4 band belt.

The rotor drive pump is variable displacement. An electrically operated valve destrokes the pump when the thresher clutch is disengaged. A pressure Iimiter protects the rotor drive system by destroking the pump at high pressures.

The rotor drive motor is fixed displacement. The output shaft of motor is connected directly to a 2-speed gearbox, which drives the rotor.

Case (drain) pressure must not be higher than 276 kPa (40 psi). The case return lines carry the pump and motor leakage and other return oil back to the cooler and reservoir.

If a hose fails, the loss of charge pressure will cause the hydrostatic pumps to destroke to neutral. Continued running of the engine after loss of hydraulic oil can cause damage to the charge pump and hydrostatic pumps. Shut engine down at once when monitor shows low oil level.

All high pressure hoses are specifically selected for the high pressures encountered in these systems 44.8 mPa (6500 psi) in the propulsion drive, 48.3 mPa (7000 psi) in the rotor drive).

The rotor speed is controlled by a switch in the cab and an electric displacement controller on the pump.

Charge pressure setting is 2309-2654 kPa (335-385 psi) above case pressure when the rotor pump is in neutral (destroked). When the rotor pump is in forward or reverse (in stroke), charge pressure is approximately 172 kPa (25 psi) less than above figures. Charge pressure is used for replenishing the closed loops, flushing and cooling the systems and shifting the variable swash plates in the pumps. Charge pressure settings at the motor are set approximately 137 kPa (20 psi) less than the pump.

Case (drain) pressure must not be higher than 276 kPa (40 psi). The case return lines carry the pump and motor leakage and other return oil back to the cooler and reservoir.

The propulsion drive pump is driven by the rotor pump, providing oil under high pressure to rotate the propulsion drive motor. Pump and motor are connected by hydraulic hoses in a closed loop circuit.

The output shaft of the motor is connected directly to the transmission gearbox.

The propulsion drive pump is a variable displacement type, which varies the amount of oil sent to the motor to change the ground speed.

The propulsion drive motor is fixed displacement. The pump output determines the speed and direction of rotation of the driven motor. The pump output is controlled by a ground speed lever in the cab.

NOTE: Two additional fixed displacement wheel motors, and control valve, are installed in parallel with propulsion drive motor when optional power rear wheel drive is installed.

Charge pressure setting is 2689-2896 kPa (390-420 psi) above case pressure when the propulsion pump is in neutral (destroked). When the propulsion pump is in forward or reverse (in stroke), charge pressure is approximately 172 kPa (25 psi) less than above figures.

Charge pressure is used for replenishing the closed loops, flushing and cooling the systems and shifting the variable swash plates in the pumps. Charge pressure settings at the motor are set approximately 137 kPa (20 psi) less than the pump.

The rotor drive pump is variable displacement. An electrically operated valve destrokes the pump when the thresher clutch is disengaged. A pressure Iimiter protects the rotor drive system by destroking the pump at high pressures.

The rotor drive motor is fixed displacement. The output shaft of motor is connected directly to a 2-speed gearbox, which drives the rotor.

The rotor speed is controlled by a switch in the cab and an electric displacement controller on the pump.

Part of the oil flows through the rotor drive pump, motor and gearbox to cool and lubricate these components.

Charge pressure setting is 2309-2654 kPa (335-385 psi) above case pressure when the rotor pump is in neutral (destroked). When the rotor pump is in forward or reverse (in stroke), charge pressure is approximately 172 kPa (25 psi) less than above figures. Charge pressure is used for replenishing the closed loops, flushing and cooling the systems and shifting the variable swash plates in the pumps. Charge pressure settings at the motor are set approximately 137 kPa (20 psi) less than the pump.

Case (drain) pressure must not be higher than 276 kPa (40 psi). The case return lines carry the pump and motor leakage and other return oil back to the cooler and reservoir.

The propulsion drive motor is fixed displacement. The pump output determines the speed and direction of rotation of the driven motor. The pump output is controlled by a ground speed lever in the cab.

NOTE: Two additional fixed displacement wheel motors, and control valve, are installed in parallel with propulsion drive motor when optional power rear wheel drive is installed.

Charge pressure setting is 2689-2896 kPa (390-420 psi) above case pressure when the propulsion pump is in neutral (destroked). When the propulsion pump is in forward or reverse (in stroke), charge pressure is approximately 172 kPa (25 psi) less than above figures.

Charge pressure is used for replenishing the closed loops, flushing and cooling the systems and shifting the variable swash plates in the pumps. Charge pressure settings at the motor are set approximately 137 kPa (20 psi) less than the pump.

Case (drain) pressure must not be higher than 276 kPa (40 psi). The case return lines carry the pump and motor leakage and other return oil back to the cooler and reservoir.

If a hose fails, the loss of charge pressure will cause the hydrostatic pumps to destroke to neutral. Continued running of the engine after loss of hydraulic oil can cause damage to the charge pump and hydrostatic pumps. Shut engine down at once when monitor shows low oil level.

All high pressure hoses are specifically selected for the high pressures encountered in these systems 44.8 mPa (6500 psi) in the propulsion drive, 48.3 mPa (7000 psi) in the rotor drive).

The propulsion drive pump is driven by a 3-band belt from the rear of the engine. The propulsion drive pump supplies oil under high pressure to rotate the propulsion drive motor. Pump and motor are connected by hydraulic hoses in a closed loop circuit.

The output shaft of the motor is connected directly to the transmission gearbox.

The propulsion drive pump is a variable displacement type, which varies the amount of oil sent to the motor to change the ground speed.

General Information HYDROSTATIC DRIVES Hydrostatic Oil Filter FIG. 157: The oil filters are a 10 micron spin-on canister type. The oil filters must be replaced after the first 50 hours of operation. Then every 250 hours after that.

NOTE: Take necessary precautions to prevent hydraulic fluid from draining onto machine.

Loosen vent cap fitting on the front side of filter head to prevent siphoning of oil when canister is removed.

Prime new elements by filling with clean hydraulic oil slowly into the main threaded opening, permitting time for the oil to fill the canister. Replace canisters and tighten securely by hand. Tighten vent on filter head.

NOTE: 670 combine has two hydrostatic oil filters.

General Information AIR CONDITIONING SYSTEM The air conditioner system uses an HFC R134A refrigerant. The air conditioner contains four basic components: Compressor - on the engine Condenser - in front of the radiator Expansion valve - under the cab Evaporator - under the cab From the compressor, high pressure gas is sent to the condenser, where the gas is changed to a liquid and heat is removed. The high pressure liquid flows to the expansion valve, where the liquid is metered and the pressure is reduced. At the evaporator, the liquid changes to a gas, taking heat from the air. The cycle is then repeated as the gas returns to the compressor.

IMPORTANT: When the combine is out of use for an extended period of time, start the engine and operate the system for a moment once a month in cold weather and once every two weeks in warm weather. This will pump oil to the compressor seal to prevent the seal from drying out with the loss of refrigerant. Run the compressor only when the engine compartment is above 0 degree C (32 degrees F).

m

WARNING: Lower header or feeder to the ground. Stop combine engine and remove start key before beginning any lubrication or maintenance function.

Condenser FIG. 160: The condenser (1) must be kept clean so air can pass through to cool the refrigerant. If blocked, the refrigerant pressure will increase, and a high pressure switch will disconnect power to the compressor clutch.

Check the condenser every 10 hours of operation or daily for chaff and dust deposits and clean as necessary.

General Information Air Filter Cleaning Procedure FIG. 164: Check the primary and secondary cab air filters weekly and clean as follows. Severe conditions will require cleaning more frequently.

•

Blowing with compressed air - Direct dry compressed air at less than 690 kPa (100 psi) up and down the filter in the opposite direction of normal air flow. Keep at least 25 mm (1 in) between the nozzle and panel, and continue blowing until no more dust is being removed.

•

Tapping - Hold the panel in both hands, holding opposite frames, and tap the panel on a flat surface with the dirty air side down. Dust will loosen and fall off the surface.

•

Washing - If the element is full of oil or soot, the element will need to be cleaned by washing in warm water 49 degrees C (120 degrees F) or less and a non-sudsing house hold detergent.

If using a water hose 276 kPa (40 psi) or less apply the water to the inside of the element, washing the dirt outside. Dry completely before using. With proper care, filters can be cleaned many times, with only a slight loss in performance. Filters must be replaced every year.

NOTE: When installing the filter, note the air flow direction indicated on the filter frame.

General Information STORAGE PREPARATION

Engine

When the combine is to be out of service over an extended period of time, prepare the combine for storage following the operations below:

Clean all the external parts of the engine.

Combine

Clean the crankcase breather hose. Replace the oil filter and fill the oil pan with new lubricating oil.

The following procedure will help to reduce rodent damage or insect infestation of the grain left in the combine after the harvest.

Open the stone trap, unloader, and all elevator doors and run the unloading and threshing mechanism with the cleaning fan in the highest speed position for approximately 15 minutes.

Run the left front wheel onto a block of wood, and using either high pressure water or air, clean the grain tank.

Clean the feeder, grain pans, sieves, augers, and elevators (in that order).

Run the engine until operating temperature is reached.

Stop the engine and drain the oil pan.

Service the air cleaner.

Check the coolant level and antifreeze protection.

Remove the batteries and store in fully charged condition.

NOTE: Do not store batteries on a concrete floor.

m

CAUTION: Always vent combine exhaust system to the outside. NEVER operate engine in a closed building without correct ventilation.

After cleaning the combine, permit the combine to drain and dry out, then store under cover. Leave all the elevator doors open. The wheels must be lifted up and blocks put under the axles to protect the tires. The right side of the combine must be lifted higher to permit water to run out of the grain tank if stored outside.

PREPARATION FOR USE AFTER STORAGE

Fumigate and use rodent repellent within one week of storing. Use the repellent only as recommended and authorized by the manufacturer and local authorities.

Install the chains and adjust idlers. Check alignment.

Clean the machine completely (including the engine compartment). Clean the area above the cleaning fan housing and inside the fan screens. Make sure the drain holes in the bottom of the fan housing are open.

Combine Check all the belts and adjust tensioners as required.

Check the transmission, final drives, and hydraulic oil levels. Inspect for leaks and repair. Add lubricant if necessary.

Check the operation of the air conditioning system. If the air conditioning is not operating correctly, repair.

Remove the chains. Wash in solvent and soak in oil to lubricate the chains and prevent rust.

Close the grain tank doors, elevator doors, and stone trap.

Lubricate the combine completely and service according to the Lubrication & Maintenance chart.

CAUTION: Make sure all shields, covers, access doors and guards are installed and in proper position.

Retract all of the hydraulic cylinders and cover shown parts of the piston rods with grease.

During extended storage, start the engine at least once a month and run the air conditioner compressor for a moment to lubricate the shaft seal and to prevent loss of refrigerant.

IMPORTANT: In cold temperatures, to prevent damage to the compressor unit, Do not turn the air conditioner on until the compressor has heated up from the heat of the engine.

If the engine is not able to be operated, turn the compressor shaft over multiple times by hand to lubricate the shaft seal.

Service the cab filters.

01-116

Check the tire inflation.

FIG. 166 FIG. 166: Metric capscrews are known by the grade number stamped on the head of the capscrew or on the surface of metric nuts. The higher the number, the higher the strength of the capscrew.

NOTE: Do not use these values when the torque values are specified in another section of the manual.

These values are for clean, dry threads. Reduce the value by 10% when lubricant is used. Reduce the value by 20% if new plated capscrews are used.

Capscrews threaded into aluminum must have two diameters of thread engaged and can require 30% more reduction in the torque.

General Information TAP DRILL SIZES - S.A.E. & METRIC The tap drill sizes shown in the chart below gives the theoretical drill size for a 60 percent or a 75 percent thread depth. Generally, drill sizes must be selected from the 60 percent thread chart as these sizes will provide a thread which will have approximately 90 percent of the maximum holding strength. Drill sizes from the 75 percent thread chart are recommended for soft metals or for shallow holes tapped in mild steel when thread engagement will be less than 1.5 times the thread diameter.
