washer with a screwdriver by applying finger pressure (without any
prying). - Adjust wheel bearing play.
- To adjust, tighten hex nut while rotating wheel in order to avoid stress
on bearing.
- Secure hex nut with castellated lock and new cotter pin.

CAUTION!
Always replace the grease cap. Any damage to the cap will allow
moisture in, which can destroy the wheel bearing. - Install grease cap.
