I just split my Final drive, due to large amounts of sludge in my new found bike. I disassembled everything for soaking and cleaning, and am curious about other peoples experiences. When I removed the Ring gear retainer, I marked the orientation with two small punch marks. When I retorque everything, I'm assuming that the preload should be close when I torque to the marks?



Any experiences, or any input?

Thanks guys!

You need to tighten that ring gear bearing retainer to a specified torque of 29 ft-lb, then back it off and re-torque to 7 ft-lb pre load . These torque values are in addition to any torque needed to overcome the friction from the o-ring. I used a 4" metal electrical ceiling box with an old socket brazed onto it as a "wrench" so I could use my torque wrench to turn the bearing retainer. I put the corner screws in the box backwards to engage the teeth in the ring gear bearing retainer.

wow, thanks

I forgot to ask: Have you ever removed the front input pinion to check both bearings? After washing out both haves, I now notice a slight noise from the 'rear' bearing behind the bevel gear. (in the housing assy)



Press fit maybe, requiring the whole pinion and race to be removed?

I never messed with the pinion gear. The complete final drive overhaul is in the manual. find it here link to manuals

The other bearings seem fine, but my pinion seems to have a dragging feeling in certain spots of rotation. It might have a few bad balls that are scored, or a warped retainer or housing.



Now time to find another unit, because I have no idea how to remove that pinion.



Anyone remove the front input stack up? Or just buy another whole drive?



thanks
