CHAINCASE SEAL/BEARING
REPLACEMENT
1. Remove the chaincase as described above.
2. Pry out the old seals (P,Q) from the back side of the
chaincase.
3. Remove bearing retaining snap rings (L,U).
4. Press out the old bearings (M,T) from the back side of the
chain case so that the bearings drop out of the front. If the
bearing pushes out hard, warm the area to expand the
chaincase bore slightly.
NOTE: When removing always push out the bearing
towards the snap ring side of the chaincase.
5. Clean the chaincase.
6. Apply Loctite 680 to the outer race of the new bearings and
press them into the chaincase from the snap ring side.
NOTE: Press on the bearing outer race only, or
damage may occur to bearing.
7. Replace the snap rings (L,U).
8. Press in new seals (P,Q) in the back of the chaincase until
the outer edge of the seal is flush with the chaincase
shoulder.
