Hub Sub-Assembly

1. Put hub on a table with the tapped holes facing

down.

2. Using a flat plate in conjunction with a pressing

tool, press in the seal so it is flush with the edge of

the hub.

NOTE:

The seal has a thin outer shell that can be easily dam

aged if not installed with care. It is a good idea to

start the seal into the bore with a rubber mallet

before pressing.

3. Flip the hub over.
4. Using an appropriate pressing tool, press the main

bearing into the bore until it bottoms out.
