The loader has 2 independent final drive housings. When
checking the oil level ensure the loader is on a level sur-
face.

engage the boom support pins. Shut off the engine.
2 Remove the top (upper) check plug located between
the 2 tires at the very front of the loader. (fig. C597)
The oil level should be at the top of the check hole with a
little to trickle out.
Adding Oil
Oil should be added with the loader on a level surface.

engage the boom support pins. Shut off the engine.

IMPORTANT
Check the final drives
closely for damaged seals
or other leaks if the oil

Changing The Oil
Ensure the loader is on a level surface before changing
the oil.

friendly manner. If the oil is contaminated, remove the
side inspection cover to flush the housing. (fig. C2073)
