er tube as follows:
1. Clean dirt from grease fitting.
2. Loosen the gearcase clamp bolt.
3. Remove the index bolt from the gearcase.
4. Slide the gearcase out of the tube. Using a grease gun,
pump urea-base grease (about 10 grams) into the grease fit-
ting on the gearcase.
5. Clean up excess grease, then reassemble the gearcase
onto the outer tube. Make sure the index bolt fits into the hole
on the outer tube. Securely tighten both bolts.
