c.Slide the gearcase out of the tube.

Using a grease gun, pump lithium- base grease (about 10 grams) into the grease fitting on the gearcase until you see old grease being purged from the gearcase (Figure 29). Purged grease will be visible in the outer tube cavity. 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.
