LUBRICATION 3.2
Checking The Oil Level
The loader has 2 independent final drive housings. When
checking the oil level ensure the loader is on a level sur-
face.
1 Remove any attachment, raise the boom arms and
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. C5014)
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.
1 Remove any attachment, raise the boom arms and
engage the boom support pins. Shut off the engine.
2 Remove the small inspection cover located to the rear
of the steering lever. (fig. C5017)
3 Remove the oil level check plug as outlined above.
(fig. C5014)
4 Remove the vented filler plug. (fig. C5077)
5 Add 10W30 API classification SJ oil until it begins
to flow out the upper check hole. Total final drive hous-
ing capacity per side is 1.9 gal (7 liters).
6 Replace all plugs.
WARNING
IMPORTANT
Check the final drives closely for damaged seals or
other leaks if the oil level is excessively low.
Never work under a raised boom arm without the
boom supports engaged and the engine shut off.
Changing The Oil
Ensure the loader is on a level surface before changing
the oil.
1 Remove any attachment, raise the boom arms and
engage the boom support pins. Shut off the engine.
2 Slide a drain pan under one of the lower drain plugs
located at the front of the loader, between the 2 front
wheels. (fig. C5014) Be prepared to contain 1.9 gal (7
liters) of oil per side.
3 Remove the drain plug. Allow the oil to drip com-
pletely out of the final drive housing. Replace the drain
plug . Dispose of the waste oil in an environmentally
friendly manner. If the oil is contaminated, remove the
side inspection cover to flush the housing.
4 Replenish the oil as outlined above in Adding Oil
with 10W30 API classification SJ oil.
