Replace Drive Hub Oil
Replacing the drive hub oil is essential for good
machine performance and service life. Failure to
replace the torque hub oil may cause the machine
to perform poorly and continued use may cause
component damage.
1 Select the drive hub to be serviced. Drive the
machine until one of the two plugs is at the
lowest point.
2 Remove both plugs and drain the oil into a
suitable container.
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.
Refer to Section 2, Specifications.
5 Apply pipe thread sealant to the plugs. Install
the plugs.
6 Repeat steps 1 through 5 for all the other drive
hubs.
