MAJOR COMPONENTS & SPECIFICATIONS Truck And Engine

Operator's Cab

The 930E-4SE Dump Truck is an off-highway, rear dump truck with AC Electric Drive. The gross vehicle weight is 1,114,670 lbs. (505,611 kg). The engine is a Komatsu SSDA18V170 rated @ 3500 HP (2611 kW).

The operator cab has been engineered for operator comfort and to allow for efficient and safe operation of the truck. The cab provides wide visibility with an integral 4-post ROPS/FOPS structure and an advanced analog operator environment. It includes a tinted safety-glass windshield and power-operated side windows, a deluxe interior with a fully adjustable seat with lumbar support, a fully adjustable/tilt steering wheel, controls mounted within easy reach of the operator, and an analog instrument panel which provides the operator with all instruments and gauges which are necessary to control and/or monitor the truck's operating systems.

Main Alternator The diesel engine drives an in-line alternator at engine speed. The alternator produces AC current which is rectified to DC within the main control cabinet. The rectified DC power is converted back to AC by groups of devices called "inverters", which are also within the main control cabinet. Each inverter consists of six phase modules under the control of a gate driver power converter (GDPC). The two GDPCs control the operation of each phase module.

Each phase module contains paired positive and negative semiconductor switches referred to as insulated gate bipolar transistors (IGBT). The IGBTs cycle on and off at varying frequencies to create an AC power signal from the DC supply.

The AC power signal produced by each inverter is a variable-voltage, variable-frequency (VVVF) signal.

Frequency and voltage are changed to suit the operating conditions.

Cooling air for the control/power group and wheel motors, as well as the alternator itself, is provided by dual fans mounted on the alternator shaft.

AC Induction Traction Motorized Wheels The alternator output supplies electrical energy to the two wheel motors attached to the rear axle housing.

The motorized wheels use three-phase AC induction motors with full-wave AC power.

The two wheel motors convert electrical energy back to mechanical energy through built-in gear trains within the wheel motor assembly. The direction of the wheel motors is controlled by a directional control lever located on the center console.

Suspension Hydrair IIÂŽ suspension cylinders located at each wheel provide a smooth and comfortable ride for the operator and dampens shock loads to the chassis during loading and operation.

FAM0215 9/09

Power Steering The truck is equipped with a full time power steering system which provides positive steering control with minimum operator effort. The system includes nitrogen-charged accumulators which automatically provide emergency power if the steering hydraulic pressure is reduced below an established minimum.

Dynamic Retarding The dynamic retarding is used to slow the truck during normal operation or control speed coming down a grade. The dynamic retarding ability of the electric system is controlled by the operator through the activation of the retarder pedal (or by operating a lever on the steering wheel) in the operators cab and by setting the RSC (Retarder Speed Control). Dynamic retarding is automatically activated, if the truck speed goes to a preset overspeed setting.

Brake System Service brakes at each wheel are oil-cooled multiple disc brakes applied by an all-hydraulic actuation system. Depressing the brake pedal actuates both front and rear brakes after first applying the retarder. All wheel brakes will be applied automatically if the brake system pressure decreases below a preset minimum.

The parking brake is a dry disc type, mounted inboard on each rear wheel motor, and is springapplied and hydraulically-released with wheel speed application protection (will not apply with truck moving).

FIELD WELDING FOR ASSEMBLY OR REPAIR When welding on Komatsu equipment, whether at initial field assembly or during normal maintenance repairs, special procedures must be followed.

Due to the continuous program of research and development, periodic revisions may be made to this publication. It is recommended that customers contact their distributors for information on the latest revision.

The welding information contained in this chapter is general information that must be followed unless otherwise specified in a detailed repair procedure provided on an engineering drawing or a detailed specific repair procedure. Additional specific information, or detailed instructions can be obtained through your local Komatsu customer support manager.

WELD PROCEDURES Electric arc welding, either the semi-automatic “MIG” (GMAW), Flux Core (FCAW), or “Stick” electrode welding (SMAW), are approved processes for field installation and maintenance welding. Welding of highly stressed structural members such as castings, torque tubes, top and bottom plates on the frame rails, and the curved intersection points of frames should be done with the specific detailed instructions from Komatsu Product Service. See Annex A for repair procedures. These repair procedures are detailed instructions for most high stressed structural members.

APPROVED CONSUMABLES WELDER QUALIFICATION AND TRAINING

GMAW - LW102-15 or ER80S-D2

The welding technique must be of the highest standard to produce the soundest weld possible. Only welders who have been trained and qualified for structural steel welding in all positions, in conformance with the American Welding Society (AWS) D1.1 or (AWS) D14.3 only, are allowed to perform the welding. The welding instructions for field assembly of Komatsu components are normally provided by engineering drawings. Additional detailed welding instructions for field repairs are provided in the field repair manual SEB14001. A full understanding of the AWS standard welding symbols is necessary to perform and inspect such field welds. Weld sizes specified on the drawings are intended to reflect minimum requirements.

SMAW - E7018-1, E8018-C1, or E8018-C3

FCAW - E70T-5, E71T-8, or E71T8-NI1

WELD QUALITY REQUIREMENTS 1. Each weld must be homogeneous with low porosity, free from cracks, and slag inclusions.

2. Each weld must have complete fusion between the base metal and weld metal added by the electrode.

3. All welds must be reasonably smooth, without excessive deformity, and all craters filled. No cracks are permitted.

4. The toe of a weld to a stressed member must have a smooth transition. Excessive convexity in multi-pass fillet welds is not permitted. Excessive convexity produces high residual stress in the throat of the weld, and is not permitted.

5. Undercut in excess of 0.8 mm (0.03 in.) on critical welds must be reworked by the application of welding an additional cover pass. It is important that this pass is blended with the existing weld.

FAM0403

Field Welding For Assembly Or Repair

4-1

6. When welding in the vertical position, always weld using the vertical up technique. Large wash weld weaves should not be used when welding on truck frames. Properly applied multiple pass welding is the required procedure on truck frames.

2. Low Ambient Temperature - DO NOT weld in temperatures below 50°F (10°C). At low temperature conditions, preheating of all welding joint work areas is required. See preheat and post heating requirements as detailed in Annex A.

7. Slag is to be removed from all weld beads, and must be completely removed before each pass in a multiple pass procedure. It is also required that all slag is removed and tie in all areas.

Grind all welds where a weld crosses or intersects with another weld.

3. Weld Cooling - Protect the weld area from a rapid cooling rate. Heat retardation may be accomplished through the use of heat lamps, torches, insulating blankets, etc.

MATERIALS, CONTROLS, AND PRECAUTIONS The steel used in the fabrication of all Komatsu equipment is of high strength low alloy (HSLA) material of different grades. The standard dump body main plates are made from abrasion resistant materials. These materials offer themselves very well to welding during fabrication, and repair.

The welding consumables are often supplied by Komatsu America Corp. with the new equipment as part of the field welding / assembly package. For field welding and repairs, the approved consumables as detailed, should be procured from a local, reliable supplier. Other highly specialized welding consumables are available but have limited use on Komatsu structural components. Approval is required from your Komatsu customer support manager.

4. Moisture - Any moisture on the steel surfaces to be welded must be removed before welding.

Electrodes must be stored in sealed containers until needed. Electrodes must be kept in a warming oven at the work location until used to prevent any moisture absorption which might affect weld quality.

5. Foreign Materials - Any foreign substances (dirt, paint, rust, scale, and carbon deposits from cuttings) must be removed prior to welding. Clean all weld areas and surfaces with a grinder to ensure that all foreign materials have been removed.

WELD INSPECTION

Control of the welding area environment is essential for producing proper and sound welds. Essentially, five areas require attention and control.

All welding repairs are subject to inspection by a Komatsu appointed inspector or laboratory to insure quality. After the weld has been made it can be inspected by a number of non-destructive evaluation techniques. The inspections can include any of the methods listed below. All assembly welds and weld repairs that are deemed unacceptable by the inspector must be corrected at no additional cost to Komatsu. All weld repairs are also subject to additional inspection.

1. Air Movement - Avoid areas where air movement from wind, drafts, or blowers is prevalent.

This is particularly important when a shielding gas is being used as part of the welding process.

1. Visual Inspection - This is the process of looking for potential defects such as undersized welds that can be checked with weld gauges for, surface cracks, surface porosity, craters, and undercuts.

4-2

Field Welding For Assembly Or Repair

FAM0403

RECORDS 2. Dye Penetrant Inspection - This is an easily applied process which indicates cracks or surface conditions. The process is relatively inexpensive, but does not produce a permanent record except by normal photography.

3. Fluorescent Penetrant Inspection - Similar to dye penetrant inspection. This process uses a black (ultraviolet) light for increased efficiency and accuracy.

4. Magnetic Particle Inspection - This process requires special equipment that is usually more costly than the dye penetrant inspections. This process does not provide a permanent record except by normal photography.

5. Ultrasonic Inspection - This is a popular method of examining weld discontinuities. Specialized equipment and operator certification is required.

With some equipment printed data is available of the test providing a permanent record. Also, operator records with equipment settings and test results are normally recorded.

6. X-Ray Inspection - This process provides a view of the weld and base materials but it is highly specialized. This procedure provides a permanent visual record, but is more expensive than most other inspection techniques.

Komatsu requires record keeping of all welding work.

This information is valuable when personnel or job conditions change. The service and warranty departments of Komatsu must be provided with inspection reports and photographs of the weld area before, during, and after the repair. The photographs must be clear and close enough to show the weld joint preparation complete, with backer bars installed, etc. just prior to welding. These photos easily identify if the required preheating and post heating have been done with a three inch circumference around the weld repair area. Without this documentation, Komatsu will not cover any weld repair claim made under warranty. No exceptions will be made.

ANNEX A The following are general repair procedures, which must be followed for all repair and rework of major load carrying members on Komatsu equipment.

1. The repair or rework area must be protected from wind and moisture during the entire procedure. If the repair work is to done outside additional precautions must be taken to protect the weld repair process from outside elements. All welding should be done at an ambient temperature of 10°C (50°F) or above.

2. Clean and grind the entire repair area to remove all rust, grease, oils, paint, and any other foreign materials likely to contaminate the weld.

FAM0403

Field Welding For Assembly Or Repair

4-3

3. Air arc the entire crack leaving a V-shape joint.

The depth of the V (or U shaped) joint will be determined by the depth of the crack. The width to depth ratio should be approximately 1.25:1 and never less than 1:1. All cracks through the parent material will require a slightly wider root opening than the original, usually 6 mm (0.25 in.) to allow the installation of a backup strip.

Backup strips are required for all cracks that have gone through the parent material and cannot be welded from both sides. If a weld repair allows access to both sides of the plate, no backup strip is required as long as complete weld penetration is achieved. If backup strips are not used, the surface profile on both sides must be ground smooth with no undercut. Documentation must support this repair. Photographs of surface condition are required by the service and warranty departments of Komatsu.

4. Use dye penetrant to ensure the cracks are completely removed.

5. After air arcing and inspections (Steps 3 & 4) all areas cut by the air arc should be cleaned thoroughly with a grinder to remove all possible carbon deposits and dye penetrant.

6. Fill gouges with weld and grind all surfaces smooth to avoid defects in the new weld.

7. Grind all surfaces to be welded so they are free of slag, rust, and any other foreign materials.

8. Preheat the entire weld joint area until the surrounding surface area reaches 150°C (300°F) at a distance of 76 mm (3 in.) from all areas to be welded.

4-4

9. All welds are to be made with approved consumables only. The SMAW (Stick) welding rod must be used within four hours after being removed from a new sealed container or from a 52°C (125°F) minimum drying oven. Any rod that exceeds this exposure time must be dried for one hour at 427°C (800°F) before being used. Keep all weld starts and stops to a minimum.

10. When the weld is complete, immediately (before the weldment cools) post heat the entire weld area to 150°C (300°F). Even if the area is over 150°C (300°F) heat must be applied to maintain this temperature for 15 minutes, and then allow it to cool slowly. In some cases this might require wrapping with insulation blankets.

11. Grind all butt-welded repairs smooth using 36 or finer grit grinding material. All grinding marks should be parallel to the direction of primary stress if possible (and if known).

12. Hammer peen the toes of repair fillet welds as detailed in Annex B, see attached.

13. Inspect repaired areas (for surface defects) using magnetic particle or dye penetrant inspection procedures.

14. If surface defects are found, remove all defects by grinding to a maximum depth of 1.5 mm (0.06 in.). Larger defects must be removed as per the above mentioned procedures. All spot welding also requires preheating and post heating.

4. 6 mm (0.25 in.) diameter spherical tip bit 5. Protective clothing, gloves, includes eye, face, and ear protection.

3. Adequate air supply 4. Adequate lighting 5. Protective clothing, gloves, includes eye, face, and ear protection

Procedure 1. The toe of the weld should serve as a guide for the peening tool resulting in the area of deformation being approximately equally divided between the base material and the weld metal face to the specified depth and not to exceed 5 mm (0.19 in.) in width. Refer to Figure 4-1.

Procedure

NOTE: Peening shall only be performed after weld acceptance by visual inspection.

1. The toe of the weld should serve as a guide for the burr tool resulting in the material removed being approximately equally divided between the base material and the weld metal face to the specified depth and not exceed 8 mm (0.31 in.) in width. Refer to Figure 4-2.

2. The weld must have a smooth profile and the toe must have a good transition to the parent material (no overlap) before the peening operation is performed. Grinding the weld face and toe area is permitted to correct unacceptable conditions. Visual inspection/acceptance is to be done after peening with the appropriate radius and depth gauge.

2. The weld must have a smooth profile and the toe must have a good transition to the parent material (no overlap) before the grinding operation is performed. Grinding the weld face and toe area is permitted to correct unacceptable conditions. Visual inspection/acceptance to be done after grinding with the appropriate radius and depth gauge.

3. Hold the hammer tool at approximately one half the included angle between the weld face and the parent material and perpendicular to the direction of travel. This will normally require approximately four passes of the peening tool with the pressure of near full operator weight being applied. The depth of the indentation must be between 0.6 mm to 0.8 mm (0.02 to 0.03 in.).

3. The axis of the tool should be maintained at about 45° to the parent plate and inclined at about 45° to the direction of travel. The depth of the grinding must be between 0.8 mm to 1.0 mm (0.030 to 0.040 in.). The final surface must be clean, smooth and free of all traces of undercut or slag.

Anytime the engine is on: • Do not open any of the cabinet doors or remove any covers.

• Do not use power cables for hand holds or foot steps.

• Do not touch retarder grid elements.

Before opening any cabinets or touching a grid element or a power cable, the engine and all warning lights must be off.

Engine Stop Procedure Prior To Maintenance Perform the following procedure prior to maintenance to ensure that no hazardous voltages are present in the AC drive system.

1. Before turning off the engine, verify the status of all the drive system warning lights on the overhead display panel. Use the lamp test switch to verify that all lamps are functioning properly.

2. If all red drive system warning lights are off, turn the engine off.

3. After the engine has been off for at least five minutes, inspect the link voltage lights. The lights are located on the exterior of the main control cabinet and back wall of the operator's cab (DID panel). If all lights are off, the retarding grids, wheel motors, alternator, and power cables connecting these devices are safe to work on.

Locate the GF cut-out switch in the access panel on the left side of the main control cabinet. Place the switch in the CUTOUT position.

This will prevent the alternator from re-energizing and creating system voltage until the switch is returned to its former position.

After repairs, replace all covers and doors and place the GF cutout switch and battery disconnect switches in their original positions. Reconnect all harnesses prior to starting the truck.

Leave the drive system in the rest mode until the truck is to be moved.

4. If the red lights on the exterior of the control cabinet and/or the back wall of the operator's cab continue to be illuminated, a fault has occurred.

Leave all cabinet doors in place. DO NOT touch the retard grid elements. DO NOT disconnect any power cables or use them as hand or foot holds.

Notify your Komatsu customer service manager immediately. Only qualified personnel, specifically trained for servicing the AC drive system, may perform this service.

General Welding Guidelines 1. Open the battery disconnect switches and disconnect the battery charging alternator lead wire.

2. Disconnect all electrical harnesses from the Engine Control System (ECS). The ECS is located inside the electrical cabinet behind the operator's cab. Disconnect the ground strap from the ECS. 3. Fasten the welding machine ground (-) lead to the piece being welded. The grounding clamp must be attached as near as possible to the weld area.

4. DO NOT weld on the rear of the control cabinet!

The metal panels on the back of the cabinet are part of the capacitors and cannot be heated.

5. DO NOT weld on the retard grid exhaust louvers.

6. Some power cable panels throughout the truck are made of aluminum or stainless steel. They must be repaired with the same material or the power cables may be damaged.

7. Power cables must be cleated in wood or other non-ferrous materials. DO NOT repair cable cleats by encircling the power cables with metal clamps or hardware. Inspect power cable insulation prior to servicing the cables and prior to returning the truck to service. Discard cables with broken insulation.

8. Protect power cables and wiring harnesses from weld spatter and heat.

9. DO NOT lay welding cables over or near the vehicle electrical harnesses. Welding voltage may be induced into the electrical harnesses and cause damage to components.

10. DO NOT allow welding current to pass through ball bearings, roller bearings, suspensions, or hydraulic cylinders.

GENERAL PRECAUTIONS AND INSTRUCTION 1. Clean and remove all foreign material from component mounting surfaces.

Disconnect the battery cables before welding on the truck. Failure to do so may seriously damage the batteries and electrical equipment. Disconnect the battery charging alternator lead wire before welding on the frame or its components.

2. Mount the front suspensions first so that deck substructures can be installed while other components are installed.

Fasten the welding machine ground cable to the component being welded.

4. Install the fuel return hose on the rearward most fitting on the fuel tank.

DO NOT allow welding current to pass through bearings.

5. Torque the deck mounting bolts before the exhaust tubes, etc. are installed.

DO NOT lay welding cables over truck electrical cables and harnesses. Welding voltages could be induced into the truck wiring and cause damage to components.

6. Verify all electrical connectors are free from paint and/or corrosion. Clean any connector that may be questionable.

DO NOT weld on the fuel tank or the hydraulic tank unless they have been properly purged and ventilated.

Maintain fire control equipment. Inspect fire extinguishers regularly to ensure they are fully charged and in good working condition.

3. DO NOT weld the front uprights until all upper decks are installed.

7. Do not torque the diagonal ROPS beam until after the operator cab and LH air intake tubes are in place.

8. Before installing the cab to the substructure, tap all threaded holes to remove paint.

9. Verify all wiring is properly connected before attempting to start the engine.

10. Recheck the torque on hardware installed at the factory.

HARDWARE TIGHTENING METHOD

Mark cap screws and nuts with paint or ink before tightening to the specified torque. This method provides verification that the hardware has been properly tightened.

1. Snug down all of the hardware with an impact wrench or appropriate ratchet.

2. Apply a paint mark down the side of the hardware and onto the component surface. Make sure that all of the hardware that is being tightened is marked.

3. Apply the specified torque to all of the marked hardware.

All of the marks should now be offset, showing that the hardware has been properly tightened.

Page 6-4

11. Use blocks for charging the suspension (oil & nitrogen). Follow the procedures outlined in Section 10, Appendix.

12. Steering accumulators are normally not charged with nitrogen when shipped from the factory.

Use proper precautions when checking the nitrogen pressure and oil level in the cylinder.

13. Brake accumulators are normally charged with nitrogen when shipped from the factory. Use proper precautions when checking pressures.

14. Verify the lube system is lubricated, purged and all levels full prior to start up.

15. Purge air from the steering pump before truck operation. Pressure will not build in the brake and steering circuit if air is present. Air in the system may damage the pump. Refer to the Hydraulic Checkout Procedure in Section 10 of this manual.

16. Use the battery disconnect switch when arc welding. Connect the weld ground near the weld area.

Chassis Assembly

7/10 FAM0615

To help prevent contamination that may lead to premature pump failures, flush the hydraulic system before the initial truck start-up.

17. Before the truck is started for the first time, the hydraulic system must be flushed. Refer to the following hydraulic system flushing procedure.

HYDRAULIC SYSTEM FLUSHING PROCEDURE When a new truck is assembled and the engine is started for the very first time, the hydraulic system must be flushed immediately to remove contamination that may have been introduced during the field assembly process. DO NOT start the engine unless all flushing equipment is installed and ready for use.

The flushing procedure will help eliminate harmful contamination that may lead to premature pump or valve failures. Starting the engine just one time without performing the flushing procedure may contaminate the hydraulic system.

Special hydraulic system flushing tools for the 930E truck have been released. Hoist system bypass blocks (PC3074) and steering system flushing hose (XB5777) must be on-site before or during field assembly, so when the truck is started for the first time, the hydraulic system can be flushed and any debris can be removed from the hydraulic system.

Fitting assembly (XB7075) shown as (3, Figure 6-7) will also be required.

All flushing hoses must be rated to withstand 27 580 kPa (4,000 psi) pressure. The hoses must be 1 inch inside diameter and meet SAE 100R12 specifications.

Hydraulic fluid escaping under pressure can have sufficient force to enter a person's body by penetrating the skin and cause serious injury, and possibly death, if proper medical treatment by a physician familiar with this type of injury is not received immediately.

Before disconnecting pressure lines, removing fittings or replacing components in the hydraulic circuits, or installing test gauges, ALWAYS bleed down the steering and brake accumulators.

NOTE: The hoist cylinder bypass blocks should be saved for possible use later in case the hydraulic system needs to be flushed after a component failure.

1. If the tires are installed on the truck, chock the left and right rear wheels securely on both sides to prevent truck movement. If the truck is sitting on cribbing, ensure it is secure enough to allow safe operation of the engine and clearance for turning the front spindles lock to lock without risk of collapsing the cribbing.

2. Inspect all hydraulic hoses to ensure that they are properly routed and securely connected.

3. Connect a laptop PC to the interface module.

Start the Interface Realtime Data Monitor program.

4. Ensure that both brake accumulators and both steering accumulators are properly precharged with nitrogen to 9 650 kPa (1,400 psi). Refer to the shop manual for the accumulator charging procedure.

5. Confirm that the steering pressure is released by turning the steering wheel. No steering movement should occur.

6. If any fault codes are displayed, troubleshoot the system and repair the problem before proceeding.

7. Install accurate pressure gauges at the following locations: • Pressure test port “TP3” (4, Figure 6-1) on the bleed down manifold - 35 000 kPa (5,000 psi).

• Pressure test port (1, Figure 6-2) for the front brake cooling circuit - 3 450 kPa (500 psi).

• Pressure test ports (2, Figure 6-2) on both high pressure hoist filters - 24 000 kPa (3,500 psi).

• Pressure test port (1, Figure 6-3) for the rear brake cooling circuits - 3 450 kPa (500 psi).

• Pressure test port “GPA” (2, Figure 6-4) located on the steering pump - 35 000 kPa (5,000 psi).

.

If any hydraulic pressure is detected on the pressure gauge installed at TP3, there is residual oil pressure in the system. Do not loosen or remove any hydraulic hoses, fittings or components. The steering accumulators have not been properly depressurized. Locate and correct the depressurization problem. Always relieve all hydraulic pressure before disconnecting any hydraulic lines or fittings. Always tighten all connections securely before applying pressure. Confirm that the steering pressure is released by turning the steering wheel. No steering movement should occur.

8. Ensure pressure gauge connected at "TP3" reads 0 kPa (0 psi) before removing plugs (1 & 2, Figure 6-1). Remove plugs (1 & 2) from the bleed down manifold. Connect jumper hose assembly (XB5777) between "QD supply" port and the "QD return" port on the bleed down manifold. Tighten all connections securely before applying pressure.

12. The steering pump case must be filled with oil before startup to avoid pump damage. Disconnect the hose that is connected to fitting (1, Figure 6-4). Then remove fitting (1). Fill the steering pump case with clean type C-4 hydraulic oil through the case drain port. It may require up to 2.9 liters (3 quarts) of oil. Re-install fitting (1) and reconnect the hose.

NOTE: Filling the steering pump case with oil does not eliminate the need to bleed air from the pump suction line.

19. Turn the key switch ON but do not start the engine. Verify that the low steering accumulator precharge warning is not displayed. If the warning is displayed, correct the problem before proceeding.

13. Fully open all hydraulic shutoff valves in the pump suction lines. The valves are fully open when the valve handle is in-line with the hose.

Serious pump damage will occur if any shutoff valve is not fully open when the engine is started.

14. Fill the hydraulic tank with clean type C-4 hydraulic oil. Ensure that the oil level is visible in the center of the upper sight glass.

FIGURE 6-8. BRAKE MANIFOLD 1. Accumulator Bleed Down Valves 2. Brake Manifold

15. To bleed trapped air from inside the pump suction hoses, loosen the cap screws where the three suction hoses attach to the inlet of each pump. Ensure that the O-ring does not fall out of the groove. After oil appears, retighten the cap screws to the standard torque.

16. Check the hydraulic tank oil level. If necessary, add oil.

FAM0615 7/10

Chassis Assembly

Page 6-9

20. Start the engine and operate at low idle. Within 30 seconds after starting the engine, check the two oil pressures listed below. If the oil pressure readings are not correct, stop the engine.

Locate and repair the problem before proceeding. If the pressure readings are correct, proceed to the next step. Do not turn the steering wheel or apply the brakes at this time.

• With the engine at low idle, and the oil temp at 21° C (70° F), oil pressure at the hoist filters should be approximately 552 kPa (80 psi) or less.

22. If all pump pressures and brake cooling oil supply pressures are correct as stated in Steps 20 and 21, increase engine speed to 1500 rpm and flush the system for 20 minutes. During this time, move the hoist control lever to the POWER UP position for 30 seconds, and then move it to the POWER DOWN position for 30 seconds. Repeat this hoist control cycle five times. This process will carry any system contaminants to the hydraulic filters.

Monitor the pressure gauges at the front and rear brake cooling test ports during this step.

The pressure readings should always be 0 kPa (0 psi) when the hoist valve is in the POWER UP or POWER DOWN positions, and approximately 345 kPa (50 psi) while in the HOLD or FLOAT positions.

• Oil pressure at steering pump test port "GPA" should be approximately 690 kPa (100 psi).

Do not operate the engine at low idle for more than 30 seconds. The steering pump pressure at test port "GPA" must be at or above 1 725 kPa (250 psi) during the flushing process to provide adequate internal pump lubrication. Steering pump damage will result if the pressure is below 1 725 kPa (250 psi) for more than 30 seconds.

21. If the oil pressure readings in Step 20 are correct, increase the engine speed to obtain oil pressure at test port "GPA" of 1 725 kPa (250 psi). Move the hoist control lever to the POWER UP or to the POWER DOWN position. The pressure readings at the front brake cooling port (1, Figure 6-2) and rear brake cooling test port (1, Figure 6-3) should be 0 kPa (0 psi). If the pressure is not 0 kPa (0 psi), the hoist valve piping (or pilot lines) may be connected incorrectly, or the hoist valve could be defective. Correct the plumbing problem or replace the hoist valve and repeat this step.

23. When the 20 minute flushing process is complete, turn the key switch to the OFF position and allow at least two minutes after the engine has stopped for the steering accumulators to completely depressurize.

24. Remove the adapters from both front wheel brake cooling hoses and re-connect the cooling hoses to the front brake assemblies.

25. Remove the tee fitting assembly from the three rear brake cooling hoses. Re-connect the three rear brake cooling hoses to the axle housing.

26. Check the pressure gauge connected to the "TP3" port on the bleed down manifold. If any pressure is still in the system, the bleed down process did not complete. Locate and repair the problem. If the pressure is 0 kPa (0 psi), remove the jumper hose and fittings installed in the bleed down manifold. Install the two plugs (1 & 2, Figure 6-1) previously removed back into the bleed down manifold.

27. Check the hydraulic tank oil level. If necessary, add oil.

28. Close both brake accumulator bleed down valves (1, Figure 6-8).

Page 6-10

Chassis Assembly

7/10 FAM0615

NOTE: Do not combine Step 29 with any other steps.

Do not apply the brakes or steer the truck during Step 29.

29. To flush the accumulators, start the engine and operate the engine until the pressure at the "TP3" port on the bleed down manifold is approximately 21 200 kPa (3,075 psi). This is the pressure where the steering pump unloader valve shifts and unloads the pump.

• If the accumulator pressure exceeds 21 546 kPa (3,125 psi), immediately turn the engine off and open the brake accumulator bleed down valves.

Refer to Steering pump pressure control adjustments in the shop manual, then repeat Step 29.

• If the accumulator pressure does not reach 20 856 kPa (3,025 psi), check for faults on the Interface Realtime Data Monitor program. If there is a bleed down fault active, locate and correct the problem. If no faults are active, refer to Steering pump pressure control adjustments in the shop manual, then repeat Step 29.

30. When the pressure gauge connected to "TP3" reads approximately 21 200 kPa (3,075 psi):

31. If Step 30-b results are satisfactory, open both brake accumulator bleed down valves (1, Figure 6-8) on the brake manifold to completely depressurize the brake accumulators. After all hydraulic pressure has been released, close both accumulator bleed down valves. Repeat Steps 29 - 31 five times.

32. To flush the steering system, start the engine.

Allow the accumulators to fully charge and the steering pump to unload.

33. Turn the steering wheel full left and then full right ten times.

34. Turn the key switch to the OFF position. Allow at least two minutes after the engine has stopped for the steering accumulators to completely depressurize. The pressure gauge at the bleed down manifold pressure test port "TP3" will be 103 kPa (15 psi) or less after a successful bleed down.

35. The hydraulic system flushing procedure has been completed. All hydraulic system high pressure filter elements must be replaced. a. Close both hoist pump suction line shutoff valves and the steering pump suction line shutoff valve.

a. For the first time only through this step: • Leave the key switch in the ON position, and use the engine shut down switch on the center console to stop the engine.

• After the engine has stopped, confirm that steering accumulator bleed down does not occur, and that no bleed down faults or any other faults are displayed on the Interface Realtime Data Monitor. b. The second and subsequent times through this step: • Turn the key switch to the OFF position.

Confirm that after the engine has stopped that the steering accumulator bleed down process begins.

• Confirm that accumulator bleed down completes within two minutes. Also confirm that bleed down fault A236 "Steering bleed fault" or any other bleed down fault does not become active. The pressure gauge at the bleed down manifold pressure test port "TP3" will be 103 kPa (15 psi) or less after a successful bleed down.

FAM0615 7/10

b. Remove the hoist and steering hydraulic filter elements. Clean the housings and install new filter elements. c. Open both hoist pump suction line shutoff valves and the steering pump suction line shutoff valve.

36. Remove all pressure gauges and re-install the dust caps on all quick disconnect fittings.

37. Check the hydraulic tank oil level. If necessary, add oil.

38. Proceed to the steering and brake system checkout procedures in the Field Assembly Manual.

39. After the steering and brake system checkout procedures are completed, remove hoist cylinder bypass blocks (4, Figure 6-2) and connect the hoist cylinder hoses to the hoist cylinders.

Ensure the hoses and ports are clean to prevent contamination.

NOTE: Do not to extend the hoist cylinders until the body is installed.

High tightening force is required to install the cap screws that secure the wheel motors to the rear axle housing. Repeated tightening will result in cap screw fatigue and damage.

Do not reuse any wheel motor mounting hardware (cap screws and hardened washers). Replace the hardware after one use.

Do not retighten any wheel motor mounting cap screw that has loosened after the truck has been placed into operation. If any wheel motor mounting cap screw has loosened during truck operation, all of the cap screws and hardened washers must be replaced with new hardware.

The cap screws that are used to secure the wheel motors to the rear axle housing are specially hardened to meet or exceed Grade 8 specifications. Replace these cap screws with only new cap screws of the correct hardness. Refer to the appropriate parts book for the correct part number.

The use of dry threads in this application is not recommended. Due to the high tightening force that is required to install the wheel motor mounting cap screws, dry threads may cause damage to tools, cap screws or the rear axle housing.

Komatsu does not recommend the use of special friction-reducing lubricants, such as Copper Coat, Never-SeezÂŽ or other similar products, on the threads of standard fasteners where standard torque values are applied. The use of special friction-reducing lubricants will significantly alter the clamping force during the tightening process. If a special friction-reducing lubricant is used, excessive stress and possible breakage of the fasteners may result.

94. Select the hardware to be installed in Group 1 of the tightening sequence. Refer to Figure 6-69.

95. Inspect each cap screw for rust, corrosion and surface defects on any seat or thread. Do not use any cap screw if a defect is suspected.

96. Lubricate the cap screw threads, cap screw head seats and washer faces with a lithium based grease containing 5% molybdenum-disulphide.

NOTE: The special hardened washers that are used in this application may have a punch lip on one side due to the manufacturing process. When placing this washer under the cap screw head, the washers must be installed with the punch lip facing away from the cap screw head to prevent damage to the fillet between the cap screw head and the shank. Refer to Figure 6-68.

DUMP BODY ASSEMBLY GENERAL INFORMATION

The total weight of the body is approximately 30 362 kg (66,937 lb). Use two cranes for assembling the body. A 45 metric ton (50 ton) crane and a 109-136 metric tons (120-150 ton) crane are required. The larger crane is needed to help turn the body over after completion of the underside welding.

Assembly of the body must be performed on flat terrain with an adequate area for welding machines and for maneuvering lifting equipment.

If the body is being welded in a cold climate, it is advisable to move the parts to be welded into an enclosed shop area. Surfaces to be welded must be dry and the temperature must be above 10°C (50°F).

If shop space is not available, it may be necessary to provide a portable enclosure and pre-heat the parts prior to welding.

In most instances, it is easier to assemble and weld the body while the sections are upside down. After the pivot, guide pin, and body pads are welded in place, the body can be turned over and the remainder of the assembly can be completed.

All paint must be removed from surfaces to be welded. Use a wire brush or paint removal equipment.

Refer to the assembly drawings shipped with the truck for specific welding details and the parts required for assembly.

Body sections must be assembled as originally manufactured. Match the shipping numbers stenciled on the body sections to mate the correct parts. DO NOT mix components.

SUSPENSION OILING AND CHARGING PROCEDURE GENERAL

EQUIPMENT LIST

These procedures cover the oiling and charging of Hydrair® II suspensions on Komatsu 930E dump trucks.

•

Hydrair Charging Kit

•

Jacks and/or Overhead Crane

•

Support Blocks for: Oiling Height Dimensions (Front and Rear) Charging Height Dimensions (Front Only)

•

Hydrair Oil (See Specifications Chart)

•

Friction Modifier (See Specifications Chart)

•

Dry Nitrogen (See Specifications Chart)

Suspensions which have been properly charged will provide improved handling and ride characteristics while also extending the fatigue life of the truck frame and improving tire wear.

NOTE: Inflation pressures and exposed piston lengths are calculated for a normal truck gross vehicle weight (GVW). Additions to truck weight by adding body liners, tailgates, water tanks, etc. should be considered part of the payload. Keeping the truck GVW within the specification shown on the Grade/ Speed Retard chart in the operator cab will extend the service life of the truck main frame and allow the Hydrair II suspensions to produce a comfortable ride.

Installation of Charging Kit Assemble the charging kit as shown in Figure 4-1 and attach it to a container of pure dry nitrogen (8).

1. Remove the protective covers and charging valve caps from the suspensions.

2. Turn "T" handles (1, Figure 4-1) of adapters (2) completely counterclockwise.

All Hydrair II suspensions are charged with compressed nitrogen gas with sufficient pressure to cause injury and/or damage if improperly handled.

Follow all safety instructions, cautions, and warnings provided in the following procedures to prevent any accidents during oiling and charging.

Proper charging of Hydrair II suspensions requires that three basic conditions be established in the following order: 1. Oil level must be correct.

2. Suspension piston rod extension for nitrogen charging must be correct.

3. Nitrogen charge pressure must be correct.

For best results, Hydrair II suspensions should be charged in pairs (fronts together and rears together).

If rear suspensions are to be charged, the front suspensions should be charged first.

NOTE: For longer life of suspension components, a friction modifier should be added to the suspension oil. See the Specifications Charts at the end of this section.

NOTE: Setup dimensions in the Specifications Charts must be maintained during oiling and charging procedures. However, after the truck has been operated, these dimensions may vary.

FIGURE 4-1. HYDRAIR CHARGING KIT NOTE: The arrangement of parts may vary from the illustration depending on the kit part number.

3. Ensure outlet valves (3) and inlet valve (4) are closed (turned completely clockwise).

Support Blocks For Oiling And Charging Dimensions

4. Turn swivel nut (small hex) on the charging valve three full turns counterclockwise to unseat the valve.

Before starting the oiling and charging procedures, supports should be fabricated to maintain the correct exposed piston rod extensions.

5. Attach charging valve adapters (2) to each suspension charging valve stem.

6. Turn "T" handles (1) clockwise. This will depress core of charging valve and open the gas chamber of the suspension.

7. Open both outlet valves (3).

NOTE: By selective opening and closing of outlet valves (3), and inlet valve (4), suspensions may be charged separately or together.

Removal of Charging Kit 1. Close both outlet valves (3).

2. Turn "T" handles (1) counterclockwise to release the charging valve cores.

3. Remove charging valve adapters (2) from the charging valves.

4. Tighten the swivel nut (small hex) on the charging valve. If a new charging valve is being used, tighten the swivel nut to 15 N¡m (11 ft lb), then loosen and retighten the swivel nut to 15 N¡m (11 ft lb). Loosen the swivel nut again and retighten to 6 N¡m (50 in. lb). Install the valve cap finger-tight.

5. Install the charging valve caps and protective covers on both suspensions.

Nitrogen charging support blocks for the rear suspension are no longer necessary. However, oiling blocks are necessary to properly set the oiling height.

Exposed piston rod extensions are specified for both oil level and nitrogen charging for Hydrair II suspensions. These dimensions are listed in the tables below Figures 4-2 and 4-5. Measure the dimensions from the face of the cylinder gland to the machined surface on the spindle at the front suspension. At the rear suspension, measure from the face of the cylinder gland to the piston flange.

Support blocks may be made in various forms. Mild steel materials are recommended. Square stock or pipe segments at least 25 mm (1 in.) may be used.

Blocks must be capable of supporting the weight of the truck during oiling and charging procedures while avoiding contact with plated surfaces and seals on the suspension. Refer to Figure 4-2 for front suspension support block placement and Figure 4-4 for rear support block placement.

FRONT SUSPENSION

All Hydrair II suspensions are charged with compressed nitrogen gas with sufficient pressure to cause injury and/or damage if improperly handled. Follow all the safety notes, cautions and warnings in these procedures to prevent accidents during servicing and charging.

1. Park the unloaded truck on a hard, level surface. Apply the parking brake and chock the wheels.

2. Remove the charging valve cap. Turn the charging valve swivel nut (small hex) counterclockwise three full turns to unseat the valve seal. DO NOT turn the large hex. The charging valve body has a bleeder groove in its mounting threads, but for safety of all personnel, the valve body must not be loosened until all nitrogen pressure has been released from the suspension.

3. Depress the charging valve core to release nitrogen pressure from the suspension. When all nitrogen has been released, the suspension should have collapsed slowly and be seated solidly on the support blocks. Remove the top fill plug next to the charging valve (Figure 4-2).

2. Thoroughly clean the area around the charging valve on the suspensions. Remove the protective covers from the charging valves.

Front Suspension Oiling

When blocks are in place on a suspension, they must be secured with a strap or other means to avoid accidental discharge. An unsecured block could fly loose as weight is applied, presenting the possibility of serious injury to nearby personnel and/or damage to the equipment.

Overhead clearance may be reduced rapidly and suddenly when nitrogen pressure is released.

Make certain all personnel are clear and support blocks are secure before relieving nitrogen pressure from the suspension. Wear a face mask or goggles while relieving nitrogen pressure.

NOTE: For longer life of suspension components, a friction modifier should be added to the suspension oil. See the Specifications Charts at the end of this section.

1. Position and secure oiling height dimension blocks in place (Figure 4-2). The blocks should be positioned 180 degrees apart to provide stability. When nitrogen pressure is released, the suspensions will lower and rest on the blocks. Ensure that the blocks do not mar or scratch the plated surfaces of the pistons or damage wiper seals in the lower bearing retainer. Support blocks must seat on the spindle and the cylinder housing.

4. Fill the suspension with clean Hydrair oil (with 6% friction modifier) until the cylinder is full to the top of the fill plug bore. Use drip pans and clean all spillage from the outside of the suspension. Allow the suspension to settle for at least 15 minutes to clear any trapped nitrogen and bubbles from the oil. Add more suspension oil if necessary. Install a new O-ring on the fill plug and install the plug.

Front Suspension Nitrogen Charging

Lifting equipment (crane or hydraulic jacks) must be of sufficient capacity to lift the truck weight.

Be certain that all personnel are clear of the lift area before the lift is started. Clearances under the truck may be suddenly reduced.

1. If removed, install the charging valve with new O-ring (9, Figure 4-3). Lubricate the O-ring with clean Hydrair oil.

2. Tighten valve body (6) (large hex) to 23 N·m (17 ft lb). Swivel nut (4) (small hex) must be unseated by turning it counterclockwise three full turns.

Dry nitrogen is the only gas approved for use in Hydrair II suspensions. Charging of these components with oxygen or other gases may result in an explosion which could cause fatalities, serious injuries and/or major property damage. Use only nitrogen gas meeting the specifications shown in the Specifications Chart at the end of this section.

3. Install the Hydrair charging kit and a bottle of pure dry nitrogen. Refer to Installation of Charging Kit in this section.

4. Charge the suspensions with nitrogen gas to 50.8 mm (2 in.) greater than the charging height listed in Figure 4-2. Close inlet valve (4, Figure 4-1).

5. Remove the oiling blocks from the suspensions and install the nitrogen charging blocks. Secure the blocks to prevent accidental dislodging.

NOTE: Use caution to prevent damage to plated cylinder surfaces and oil seals when installing the blocks.

6. Remove the center hose from manifold (6).

7. Open inlet valve (4) until the pressure drops below the pressure listed in Figure 4-2, then close the valve.

8. Install the center hose to manifold (6).

9. Charge the suspensions to the pressure listed in Figure 4-2. DO NOT use an overcharge of nitrogen to lift the suspensions off the charging blocks.

10. Close inlet valve (4, Figure 4-1). Leave outlet valves (3) open for five minutes to allow the pressures in the suspensions to equalize.

11. Close outlet valves (3). Remove the charging kit components. Refer to Removal of Charging Kit in this section.

12. If the charging valve is being reused, tighten swivel nut (4, Figure 4-3) to 6 N·m (50 in. lb).

13. If a new charging valve is being used, tighten the swivel nut to 15 N·m (11 ft lb)), then loosen and retighten the swivel nut to 15 N·m (11 ft lb)). Loosen the swivel nut again and retighten to 6 N·m (50 in. lb). Install the valve cap fingertight.

14. Install the protective guard over the charging valve.

15. Raise the truck body in order to extend the front suspensions, allowing for removal of the nitrogen charging blocks. Ensure that sufficient overhead clearance exists before raising the body. If the suspensions do not extend after raising the body, turn the steering wheel from stop to stop several times. If the suspensions still do not extend enough to allow for removal of the blocks, use a crane or floor jacks to raise the truck and remove the blocks.

NOTE: For longer life of suspension components, a friction modifier should be added to the suspension oil. See the Specifications Charts at the end of this section.

1. Position and secure the oiling blocks in place so the blocks are seated between the frame and the rear axle housing (Figure 4-4). A block should be used on both the left and right sides of the truck.

The front Hydrair suspensions are now ready for operation. Visually check piston extension with the truck both empty and loaded. Record the extension dimensions. Maximum downward travel is indicated by the dirt ring at the base of the piston. Operator comments on steering response and suspension rebound should also be noted.

REAR SUSPENSION 1. Park the unloaded truck on a hard, level surface. Apply the parking brake, and chock the wheels.

2. Thoroughly clean the area around the charging valve on the suspensions. Remove the protective covers from the charging valves and the rubber covers from the suspension piston.

The charging valve body has a bleeder groove in its mounting threads, but for safety of all personnel, the valve body must not be loosened until all nitrogen pressure has been released from the suspension.

3. Depress the charging valve core to release nitrogen pressure from the suspension. When all nitrogen pressure has been released, loosen and remove the fill plug. The suspension should have collapsed slowly as gas pressure was released. The weight of the truck is now supported by the support blocks.

NOTE: A plastic tube can be used to help bleed off trapped air inside the piston.

4. Remove the vent plug, pressure sensor, and charging valve (Figure 4-5). Use one of the open ports to fill the suspension with clean Hydrair oil (with 6% friction modifier). Fill until clean oil seaps from the open ports. Use drip pans and clean all spillage from the outside of the suspension. Allow the suspension to settle for at least 15 minutes to clear any trapped nitrogen and bubbles from the oil. Add more suspension oil if necessary.

5. Install the vent plug and pressure sensor onto the suspension.

6. Install a new O-ring onto the charging valve.

Lubricate the O-ring with clean Hydrair oil.

7. Install the charging valve onto the suspension.

Rear Suspension Nitrogen Charging

Lifting equipment (overhead or mobile cranes, or hydraulic jacks) must be of sufficient capacity to lift the truck weight. Ensure that all personnel are clear of lift area before lifting is started.

Clearances under the truck may be suddenly reduced.

7. Ensure that both of the suspension cylinders are extended the same distance ± 10 mm (0.39 in.). If the difference in the extension from side to side exceeds this amount, check the front suspensions for equal extension. Adjust the front suspensions as necessary.

NOTE: A low left front suspension will cause the right rear suspension to be high. A low right front suspension will cause the left rear suspension to be high.

8. Close outlet valves (3). Remove the charging kit components. Refer to Removal of Charging Kit in this section.

9. If the charging valve is being reused, tighten swivel nut (4, Figure 4-3) to 6 N·m (50 in. lb).

Ensure that the automatic apply circuit has not applied the service brakes during truck maintenance. If the front brakes are applied during rear suspension charging, the axle cannot pivot for frame raising/lowering, and the rear suspension may be unable to move up or down.

10. If a new charging valve is being used, tighten the swivel nut to 15 N·m (11 ft lb), then loosen and retighten the swivel nut to 15 N·m (11 ft lb).

Loosen the swivel nut again and retighten to 6 N·m (50 in. lb). Install the valve cap finger-tight.

1. If removed, install charging valve with new Oring (9, Figure 4-3). Lubricate the O-ring with clean Hydrair oil.

11. Install the protective guards over the charging valves. Install the rubber covers over the piston rods.

2. Tighten valve body (6) (large hex) to 23 N·m (17 ft lb). Swivel nut (4) (small hex) must be unseated by turning it counterclockwise three full turns.

The rear Hydrair suspensions are now ready for operation. Visually check piston extension with the truck both empty and loaded. Record the extension dimensions.

The Komatsu engineering department does not recommend the use of special friction-reducing lubricants, such as Copper Coat, Never-Seez®, and other similar products, on the threads of standard fasteners where standard torque values are applied.

The use of special friction-reducing lubricants will significantly alter the clamping force being applied to fasteners during the tightening process.

If special friction-reducing lubricants are used with the standard torque values listed below in Table I, excessive stress and possible breakage of the fasteners may result.

Where the torque tables specify “Lubricated Threads” for the standard torque values listed, these standard torque values are to be used with simple lithium base chassis grease (multi-purpose EP NLGI) or a rustpreventive grease (see list, page A5-2) on the threads and seats unless specified otherwise.

NOTE: Ensure the threads of fasteners and tapped holes are free of burrs and other imperfections before assembling.

STANDARD ASSEMBLY TORQUES For Class 10.9 Cap screws & Class 10 Nuts

The following specifications apply to required assembly torques for all 12-point, grade 9 (170,000 psi minimum tensile) cap screws.

The following specifications apply to required assembly torques for all metric Class 10.9 finished hexagon head cap screws and Class 10 nuts.

• Cap screw threads and seats shall be lubricated when assembled.

• Cap screw threads and seats shall not be lubricated when assembled. These specifications are based on all cap screws, nuts, and hardened washers being phosphate and oil coated.

NOTE: Unless the instructions specifically recommend otherwise, these standard torque values are to be used with simple lithium base chassis grease (multi-purpose EP NLGI) or a rust preventive grease (see list, this page) on the threads.

• Torques are calculated to give a clamping force of approximately 75% of proof load.

• The maximum torque tolerance shall be ±10% of the torque value shown.

NOTE: If zinc-plated hardware is used, each piece must be lubricated with simple lithium base chassis grease (multi-purpose EP NLGI) or a rust preventive grease (see list, this page) to achieve the same clamping forces provided below.

• Torques are calculated to give a clamping force of approximately 75% of proof load.

• The maximum torque tolerance shall be within ±10% of the torque value shown.

NOTE: Tables such as Table VIII, IX, X, and XI may be used as in the following example: Example: Convert 975 psi to kilopascals (kPa).

1. Select Table X. 2. Go to psi row 90, column 7; read 668.8 97 psi = 668.8 kPa.

3. Multiply by 10: 970 psi = 6688 kPa. 4. Go to psi row 0, column 5; read 34.475 psi = 34.47 kPa. Add to step 3.

5. 970 + 5 psi = 6688 + 34 = 6722 kPa.
