Bearings
1. Replacement
1. The main pivot and rocker pivot have single row angular contact bearings (7901 upper, 7903 lower), and the orientation is critical.
When replacing, the black rubber seal must face outwards as shown below. The blue seals all face inwards.
2. With all bearing replacement, apply a thin layer of grease to the outer bearing race or bearing bore in the frame before install.
3. It is also critical to get the new bearings to go in straight. Don’t use a hammer. An arbor press (shown below) is best. A vice is
the second best tool. If you don’t have either, we recommend having a qualified mechanic/shop do the work.
