MAINTENANCE
9. When installing, tighten until the packing surface contacts the seal surface of the filter holder, then tighten it 3/4
of a turn.
If the filter cartridge is tightened too far, the packing will be damaged and this will lead to leakage of fuel. If the
filter cartridge is too loose, fuel will also leak from the packing, so always tighten the correct amount.
When tightening with a filter wrench, be extremely careful not to dent or damage the filter.
10. Check that the drain plug at the bottom of the water separator cup is tightened securely.
Tightening torque: 0.2 to 0.45 Nm (0.02 to 0.046 kgm, 0.1 to 0.3 lbft)
11. After replacing the fuel main filter cartridge (at intervals of 1,000 hours), bleed air. For details, see "REPLACE
FUEL MAIN FILTER CARTRIDGE (PAGE 4-60)". Do not add fuel to the fuel main filter cartridge, however.
12. Start the engine, check that there is no leakage of fuel from the filter seal surface or water separator mounting
surface, then run for approx. 10 minutes at low idling.
LUBRICATE CAB MOUNT PIN (LEFT AND RIGHT: 1 PLACE EACH)
1. Stop the engine.
2. Using a grease pump, pump in grease through the grease
fittings shown by arrows.
3. After greasing, wipe off any old grease that was pushed out.
Carry out the greasing operation every day when operating in
places where the grease flows out easily, such as when
traveling through mud or water.
CHECK OIL LEVEL IN FINAL DRIVE CASE, ADD OIL
The parts and oil are at high temperature after the engine is stopped, and may cause serious burns. Wait for the temperature
to go down before starting the operation.
If there is still pressure remaining inside the case, the oil or plug may fly out. Turn the plug slowly to release the pressure, then
remove it carefully.
1. Stop the machine so that the TOP casting mark is at the top
and drain plug (P) is at the bottom.
2. Remove plug (G) and check that the oil level is near the bottom
of the plug hole.
3. If the oil level is too low, add oil through the plug hole until the
oil overflows.
4. Repeat the procedure in Steps 1 - 3 and check the oil level and
add oil to all the final drive cases (front, center, rear).
