LUBRICATION DETAILS

Grease Fittings

Lubricate all grease fittings (refer to TABLE 6) every 50 hours of operation using No. 2 multipurpose lithium base grease. Clean the grease gun and fittings before and after greasing to prevent dirt/dust.

NOTE:When operating in muddy or extremely wet conditions, lubricate the all grease fittings daily.

Engine Oil & Filter

Low-ash engine oil (Oil quality : ACEA E-9, equivalent to API standard CK-4) must be replaced.

NOTE: Using not applicable engine oil would causes clogging DPF early due to ash. Ash is the metal additives contained in Engine oil. It cannot be removed by burnt and will be accumulated in DPF.

After finishing the maintenance with carrying out DPF regeneration for a long time, replace the engine oil. There is a possibility that oil viscosity becomes lower due to mixing the fuel to the engine oil.

CAUTION: Muffler tail pipe is extremely hot just after operation, so take care not to touch it to avoid burns. Be sure to wear gloves before checking engine oil level.

Engine oil should be changed after the first 50 hours of operation and every 200 hours. Engine oil filter should be changed after the first 50 hours of operation and every 200 hours.

FIG. 105: To Check Engine Oil Level - Park tractor on level ground. Make sure to allow the engine to cool sufficiently before checking the engine. Pull out dipstick (1) and check that oil level is between upper limit, F, and lower limit, L, on dipstick. Wipe off dipstick, momentarily reinstall in engine and check oil level again. If the oil level is higher than the cut part on dipstick, replace the engine oil immediately to prevent engine trouble.

FIG. 106: To add oil, open the engine hood and remove the filler cap (2) add oil using a funnel to prevent oil from spilling. After adding oil, make sure that oil level is between upper limit and lower limit on dipstick.

NOTE: Add oil slowly to assist in venting air from the crankcase.

FIG. 107: To Change Engine Oil - Operate the tractor until oil is adequately warmed. Remove the drain plug (3) from the engine and allow all oil to drain out. Reinstall the drain plug and fill the engine oil through filler opening (2) to the upper limit on the dipstick.

FIG. 108: To Replace Engine Oil Filter - Remove the oil filter (2) from the engine and take the old filter to a proper disposal point. Make sure that the original filter gasket has been removed.

Lubricate the O-ring on the new element with clean engine oil. Turn in the new element until its sealed face comes in contact with the O-ring. Use a filter wrench to further turn in the cartridge by 3/4 turn.

(Tightening torque : 15.0 - 20.0 N・m)

Clean spilled oil and refill new oil. Start the engine, check for leaks and oil level.

IMPORTANT : Engine warranty is valid only when original engine maker manufacturer’s oil filter is used.

Transmission Oil & Filters

Transmission oil lubricates the transmission, center housing, and rear axles and also serves as hydraulic fluid. Transmission oil should be changed and the filter should be cleaned after the first 50 hours of operation and then every 400 hours thereafter.

FIG. 109: To Check Transmission Oil Level - Park the tractor on level ground. Oil level should be indicated in oil level window (1). Oil level is replenished, as necessary, by removing the filler plug (2) and adding oil through the filler opening.

NOTE: Adding oil to the transmission will also maintain correct oil level in the center housing and rear axles.

FIG. 110: To Replace Transmission Oil - Remove the drain plug (3) and completely drain oil from system.

(Tightening torque : 44.1 - 53.9 N・m)

IMPORTANT: Completely lower the 3-point linkage prior to draining transmission oil. When completely drained replace and tighten all drain plugs. Refill with oil as mentioned above.

(Only for HST TYPE)

FIG. 111: To Clean Transmission Oil Filter - Always replace the transmission oil filter while oil is removed. Carefully unscrew the oil filter (4) from its transmission. Use filter wrench.

Clean the filter adapter and lubricate the O-ring on the replacement filter adapter with clean transmission oil. Install the new filter until O-ring contacts the transmission and tighten additional 2/3 turn by hand. Do not use a filter wrench to install the filter.

(Tightening torque : 20.0 - 25.0 N・m)

Replace the cartridge after the first 50 hours, and then every 400 hours.

FIG. 112: To Clean Transmission Strainer(Suction)

- Clean the transmission oil filter while oil is removed. Loosen bolt (3) and draw out filter (1). When assembling, apply grease on O-ring (2) so as not to damage.

NOTE: After transmission oil has been replaced, or when the tractor restart after a long term of storage, or when the hydraulic system does not operate properly, consult your dealer.

Front Axle Oil

Front drive axle has a common oil level for front differential housing and each wheel reduction unit. Oil level should be checked every 200 hours of tractor operation and replaced after every 600 hours.

FIG. 113: To Check Oil Level - Park the tractor on level ground and then remove the filler cap (1). Check that the oil level is at the center of driving shaft. If necessary, fill up oil from filler cap.

To Change Oil - Park the tractor on level ground. Remove the drain plug (2) from both wheel reduction units. When all oil has drained out, replace the drain plugs. Fit the drain plugs and fill up oil.

(Tightening torque : 29.1 - 34.3 N・m)

After changing the oil, sometimes the oil level gets low after running the engine. Check the oil level after test running and make sure that there are no difference in oil level before and after the test run.

Cooling System

CAUTION: Do not open the radiator cap except when checking or replacing the coolant. Make sure to allow the engine to cool sufficiently before opening the cap. If the cap is opened while the engine is hot, coolant can pout, resulting in a burn or other injury.

Checking / Replenishing Coolant

FIG. 114: The radiator is provided with a reserve tank (1) to maintain the coolant in the radiator at the proper level. Check the level in this reserve tank during the daily inspection.

Open the hood, and make sure that the coolant in the reserve tank is between FULL and LOW levels. If the coolant level is near to the LOW level, add coolant to the reserve tank up the FULL level.

When the coolant level is below the LOW level, remove the radiator cap (2) after allowing the engine to cool sufficiently. Add coolant and make sure that there is an adequate amount of coolant in the radiator.

IMPORTANT: Do not fill the reserve tank higher than the FULL level. This will prevent the radiator from functioning optimally, and may result in leakage of coolant.

Flushing Radiator / Replacing Coolant

FIGS. 115 & 116: Pull the hose (1) out from the pole at the right side of the engine to drain coolant. Open the radiator cap (2) at the same time to allow the coolant to drain. Remove the reserve tank (3) to drain coolant from it.

Thoroughly flush out the inside of the radiator with tap water.

Set the drain hose (1) onto the pole and pour coolant into the reserve tank up to the FULL level to fill the radiator.

Securely close the radiator cap (2) and reserve tank cap, and start the engine, allowing it to run for about 5 minutes in the mid speed range (Approx. 1500 min1). Then stop the engine.

When the engine cools, the coolant in the reserve tank will be sucked into the radiator.

Add coolant to the reserve tank up to the FULL level.

Use of Anti-Freeze

Freezing of the coolant may result in damage to the engine. Mix in 50/50 anti-freeze (Long Life Coolant) when the outside temperature will drop below 0 °C (32 °F) during the winter.

The mixture ratio of anti-freeze differs depending upon the anti-freeze manufacturer and temperature. Follow the instruction for the anti-freeze.

Cleaning Radiator

WARNING: Make sure to stop the engine when cleaning the radiator. Placing your hands in this area while the engine is operating may result in serious injury.

NOTE: Before pulling out the radiator net, 1, turn the steering wheel slightly to the right. Otherwise, radiator net, 1, interferes with tire.

Cleaning Radiator Core

Wash away any dirt or other foreign matter in the fins and the radiator core (2) with water.

IMPORTANT: When the radiator becomes clogged, it will overheat, resulting in increased oil consumption.

Be careful not to apply high pressure water directly to the radiator as this may result in deformation of the fins.

Do not directly spray water on the electrical wiring or electrical parts around the engine.

Fan Belt

WARNING: Before checking the fan belt, stop the engine and remove the starter key without fail. Wait until the engine and accessories cool down completely to prevent burns.

FIG.118: The fan belt (1) is accessible from the left of the engine room by opening the engine hood. Check the belt for tension and damage.

Push down the belt with a finger at the intermediate point between the alternator (2) and crankshaft pulley (3) with a force of 10 kgf (22 lb) and see its deflection (A). If belt deflection is approximately 10 mm, the tension is proper.

When the belt deflection is improper, correct in the following procedure: a. Loosen the bolt M10 (4) and M8 (5). b. Loosen the lock nut M8 (7), and adjust the belt tension by adjustment bolt (6). c. Fix the lock nut M8 (7) for adjustment bolt M8 (6).Tighten the bolt M10 (4) and M8 (5), and check the belt deflection.

IMPORTANT: When the belt is found to be defective, ask your dealer for replacement.

Engine Air Cleaner

IMPORTANT: Never operate the engine with the air filters removed.

Cleaning / Replacing Air Cleaner Element

FIGS. 119 & 120: The engine air cleaner (1) is located above the engine. To service the engine air cleaner, gain access, open the hood.

Press the vacuator valve (2) to discharge any dirt inside. Release clips (3). Remove cover (4) and take the element (5) out of the air cleaner.

If there is moisture, wipe the inside of the air cleaner (1). If the element (5) is damaged, replace it.

IMPORTANT: Only genuine air cleaner and element must be installed to the machine.The air cleaner is designed as installing single element. Hence, do not add the second element. If the air cleaner is designed as installing double element, do not use the air cleaner with only single element. In case installing not applicable air cleaner, including replacing single to double elements, the sensor error will be occurred to measure intake air volume. As the result, it could have negative effect to control the temperature of DPF regeneration, or to estimate DPF soot accumulation.

FIG. 121: Element can be cleaned (if in serviceable condition) using following procedures:

• Using compressed air not to exceed 200 kPa from the inside of the element, remove loose dirt, grass, chaff, etc. Be careful not to damage element pleats with air flow.

NOTE: Clean the air cleaner frequently. Clogging the air cleaner causes worsening the engine combustion and clogging DPF. When cleaning air cleaner, pay attention not to damage the air flow sensor. (Do not blow the high pressure air or spray for cleaning to the sensing parts of air flow sensor.)

• After cleaning the element examine for pin holes, punctures, or tears. If the element paper, canister or seal show any signs of physical damage, the element must be replaced.

IMPORTANT: Do not hit the filter element against a rock, concrete or other hard item when cleaning it. This may result in damage or deformation of the filter element, inhibiting engine performance.

FUEL SYSTEM

Use only clean diesel fuel of correct grade. Introduction of water or dirt into the fuel tank or other portion of the fuel system can cause repeated plugging of the fuel filter and possible injection pump and injector damage.

IMPORTANT: Do not use Kerosine or heavy oil as fuel. Do not add fuel additive. Do not use diesel after long-term storage in dram can or home tank. Usage of unspecified fuel causes breakage of fuel filter, parts of fuel injection or postprocessor.

Use only ultra-low-sulfur diesel.In case to use the fuel containing much sulfur, it will be cause of poisoning DOC and DPF. Then, DPF and DOC lose the functions of cleaning exhaust gas and raising temperature of the exhaust gas.

Do not tamper with injection pump, or injector adjustment. Such tampering will spoil engine itself and / or cause severe engine damage. And warranty will not be covered for the machine with such tampering.

Fuel Filter

FIG. 122:The main fuel filter (1) and the pre-filter (2) are located the right side. Both filter remove particles in the fuel before the fuel reaches the injection pump. The main filter removes finer particles that have passed through the pre-filter. Since the drain plug (3) is attached to the pre-filter, drain the water immediately after the indicator lamp lights up. Also, periodically remove the filter bowl (case), clean to remove deposits of sediment or water, and inspect and replace the element.
