•
Use a clean rag to clean the metal surface of the
filter base where the filter gasket makes contact.
•
Reinstall the drain plug in the transmission and
clean up any residual oil.
•
Apply a light coating of clean oil on the oil filter
gasket and on the sealing surface of the base.
Install the filter by turning it clockwise, by hand,
until the gasket contacts the filter base; then
tighten the filter an additional 1/2 to 3/4 turn.
•
Slowly pour transmission oil into the fill tube while
periodically checking the oil level with the dip-
stick. Fill the transmission to the full mark on the
dipstick.
•
Screw the breather cap into the fill tube and
reinsert the dipstick into the transmission and
press firmly into place.
•
Start the engine and run at low to mid throttle for
approximately 5 minutes while actuating the
hydraulics (e.g. power steering and hydraulic lift).
IMPORTANT: Do not drive the tractor immediately
after changing the transmission oil and filter. Run the
engine for 5 minutes to prevent damage to the
transmission and/or hydraulic system.
NOTE: If hydraulically driven equipment, such as a
front loader, is installed on the tractor after the first 50
hours of operation, it is recommended that the filter
again be changed after the first 50 hours of operation
of that equipment.
Dispose of used oil in an environmentally
safe manner. If necessary, contact your area
EPA office for proper disposal procedures
and recycling center locations.
SERVICING THE FRONT AXLE
Check the oil level in the front axle frequently.
Change the oil in the front axle after the first 50 hours
of operation, then at 300 hours and every 300 hours
thereafter.
Checking the Front Axle Oil Lever
To check the front axle oil level, a viewing glass is
provided in the axle. The oil level should be
approximately half way up in the viewing glass. See
Figure 63.
Fill Plug
Adding Front Axle Oil

TABLE for the proper type and quantity of oil to add
to the front axle.
Add oil through the oil fill port on top of the axle. Refer
to Figure 63.
Changing the Front Axle Oil
•
Clean the area around the fill plugs on both the

Place a suitable container below the drain plugs,
then remove the plugs from the front axle and the
final drives inside both wheels. Refer to Figure
