I've been taking it step by step with the online shop manual but run into a problem. After telling you how to assemble and install the pinion gear and pinion bearings it later tells you te be sure and put loctite on the pinion needle bearing. So to do that now i'll have to take the pinion back out and risk ruining the threads in the case from the lock coller. My question is would the loctite really be necessary? There are some tabs, very thin tabs, that look like they are meant to keep the bearing in place. So to those who have been through this, did you loctite the needle bearing?
