MAINTENANCE PROCEDURE

CHECK OIL LEVEL IN FINAL DRIVE CASE, ADD OIL

q
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.
q
If there is still pressure remaining inside the case, the oil or plug may fly out.
Loosen the plug slowly to release the pressure.
q
Prepare a handle.
1. Set the TOP mark at the top, with the UP mark and plug (P)
perpendicular to the ground surface.
2. Remove plug (F) using the handle. When the oil level
reaches a point 10 mm below the bottom of the plug hole,
the correct amount of oil has been added.
3. If the oil level is too low, install plug (F), operate the travel
levers, and drive forward or in reverse to rotate the
sprocket one turn. Then repeat Step 2 to check again.
4. If the oil level is low, add oil through the hole of plug (F).
Add oil until oil overflows from the hole of plug (F).
5. After checking, install plug (F).
Tightening torque for plugs (F): 68.6 ± 9.8 Nm (7 ± 1 kgm)
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.
