Replace the Drive Hub Oil

Replacing the drive hub oil is essential for good
machine performance and service life. Failure to
replace the drive hub oil at yearly intervals may
cause the machine to perform poorly and
continued use may cause component damage.
Drive Hubs:
1 Select the drive 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 - 66
4 Fill the hub with oil from the top hole until the oil
level is even with the bottom of the side hole.
Apply pipe thread sealant to the plugs, and then
install the plugs.
5 Repeat steps 1 through 4 for all the other drive
hubs.
