METHOD FOR CHECKING AND ADDING OIL IN DEFERENTIAL CASE
k k
WARNING
• Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn in-
jury.
Accordingly, wait until they have cooled down before starting the work.
• If the plug is removed, oil may spurt out, so turn it slowly to release the internal pressure, then re-
move it carefully.
When getting on or off the machine with carrying oil, a tool,
etc., place it once in part (A) to ensure your safety.
1.
Remove plug (G).
2.
Check that the oil level is near the lower edge of the plug
hole.
1) If the oil level in the front differential case is low, add
oil through oil filler port (F).
Add oil until it overflows from the plug hole.
2) If the oil level in the center or rear differential case is low, add oil through the plug hole.
Add oil until it overflows from the plug hole.
