Replace the Torque Hub Oil

Replacing the torque hub oil is essential for good
machine performance and service life. Failure to
replace the torque hub oil at yearly intervals may
cause the machine to perform poorly and
continued use may cause component damage.
1 Select the torque hub to be serviced. Then
drive the machine until one of the two plugs is
at the lowest point.
2 Remove both plugs and drain the oil.
3 Drive the machine until one plug is at the top
and the other is at 90 degrees.
4 Fill the hub with oil from the top hole until the oil
level is even with the bottom of the side hole.
Then re-install the plugs.
5 Repeat steps 1 through 4 for all the other drive
torque hubs.

Replace the
Hydraulic Reservoir Filter
Replacement of the hydraulic reservoir filter is
essential for good machine performance and
service life. A dirty or clogged filter may cause the
machine to perform poorly and continued use may
cause component damage. Extremely dirty
conditions may require that the filter be replaced
more frequently.
Beware of hot oil. Contact with hot
oil may cause severe burns.
Perform this procedure with the
engine off.
1 Remove the filter with an oil filter wrench.
2 Apply a thin layer of oil to the new oil filter
gasket.
3 Install the new filter and tighten it securely by
hand. Clean up any oil that may have spilled
during the installation procedure.
4 Start the engine from the ground controls.
5 Inspect the filter and related components to be
sure that there are no leaks.
