Hub 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
damaged 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.
