4.8 Four-Wheel Drive Front Axle Adjustment and Maintenance
The tractor front axle can be divided into three chambers: the central oil chamber, the left end drive oil chamber
and the right end drive oil chamber.

The central oil chamber is in the middle of the front end of the tractor.
The oil level should be checked regularly from the sight glass. When the
oil level is low, oil should be added until the oil reaches the top line on the
sight glass. When changing the engine oil , unscrew the oil drain plug from
under the front axle and completely drain the used oil. Then, replace and
tighten the oil drain plug. Put fresh lube oil into the oil filling port
(1) and reinstall and tighten the fill plug.

When checking the oil level on the two front axle hubs, the tires should be turned
to allow access to the oil drain and fill plugs on the hubs.
The oil level should be near the top of the plug when the plug is at the horizontal
centerline of the wheel. If not add oil to the top of the sump.
When changing the oil, the front wheel should be turned to put the drain plug in Figure 4-12 Right/Left
the lowest position. Unscrew the plug, and drain the used oil. Then, roll the tire Front Hub Oil Drain and Fill
