Torque Hub
The torque hubs are mounted directly onto the rear
wheels. (Figure 5-2) It is important to keep the torque
hub oil at the proper level for lubricating these moving
parts. Be sure to change the torque hub oil every six
months.
1. Remove the plug in the 3 o’clock position. (Figure
5-2)
2. If oil comes out, no oil is needed. Reinsert the plug
and tighten.
3. If oil does not come out, remove the top plug and ll
with SAE 90 WT gear oil until oil starts to appear at
the 3 o’clock plug.
4. Replace both plugs and repeat process on the
other torque hub.

should only be done in a designated area where the
oil and chemicals can be contained. Discard these
by-products in accordance with environmental
regulations.
