.MAINTENANCE PROCEDURE
EVERY 2000 HOURS MAINTENANCE
Maintenance for every 250, 500 and 1000 hours service should be carried out at the same time.
CHANGE OIL IN FINAL DRIVE CASE
The parts and oil are at high temperature immediately after the engine is stopped, and may cause seri-
ous 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.
Loosen the plug slowly to release the pressure.
Refill capacity (each): 4.5 liters (1.2 US gallons)
Prepare a handle.
1. Set the TOP mark at the top, with the TOP mark and plug
(P) perpendicular to the ground surface.
2. Set a container under plug (P) to catch the oil.
3. Remove plugs (P) and (F) with the handle and drain the oil.
REMARK
Check the O-rings in the plugs for damage. If necessary,
replace with new ones.
4. Tighten plug (P).
5. Add engine oil through the hole of plug (F).
6. When oil begins to overflow from the plug (F) hole, install
plug (F).
Tightening torque of plugs (P) and (F):
68.6 ± 9.8 N·m(50.6 ± 7.2 lbf·ft)
REMARK
There are two plugs (F). Add oil through the one easier to
fill oil and through which no internal gears are to be seen.
CLEAN HYDRAULIC TANK STRAINER
The parts and oil are at high temperature after the engine is stopped, and may cause burns. Wait for
the temperature to go down before starting the work.
When removing the oil filler cap, turn it slowly to release the internal pressure, then remove it.
1. Loosen 6 bolts, then remove cover (1). When doing this, the
cover may fly out under the force of spring (2), so push the
cover down when removing the bolts.
2. Hold the top of rod (3) and pull up to remove spring (2) and
strainer (4).
3. Remove any dirt stuck to strainer (4), then wash it in clean
diesel oil or flushing oil. If strainer (4) is damaged, replace it
with a new part.
4. When installing, insert strainer (4) into protruding part (5) of
the tank, and assemble.
5. Assemble so that the protruding part at the bottom of cover
(1) holds spring (2), then tighten with the bolt.
