Assemble in reverse order. The following are notes to
assist you:
1. Install the snap ring into the grove in the pulley
and shaft. The sharp edge of the snap ring should
face the pulley. Install the thrust bearing next to
the snap ring (Figure 126).

2. Fill the cavity between the bearings of the hub
assembly with No. 2 general-purpose grease
before installing the pulley and shaft (Figure 127).

3. Remember the threads on the pulley and shaft
and the drive plate are left hand. Tighten firmly.
4. Install the bearings on the friction plate frame. Do
not tighten yet.
5. After the axle is installed, rotate the axle and firmly
strike each bearing with a rubber mallet. This
helps align the bearings with the axle. Secure the
bearings to the frame.
