roller bearings in drive shaft housing

Post by LeMaitre » Fri Jun 14, 2019 4:22 pm



Replacing the rear tire on GL1200A. Got the tire mounted today and when I inspected the drive shaft housing I found 3 small roller bearings and part of a basket laying in the bottom of the housing. Took a look at the final drive and the seal, they are intact. No signs of current failure with the final drive. This has led me to suspect the u-joint. Am I heading in the right direction?

Thanks for your help.

Managed to push the boot over the u-joint back. The bearings are too big to be from there. Searching through the parts list 91062-MG9-013 Bearing, needle, 20x35x18 could be where it came from. With no damage to the seal I am hesitant about tearing apart the final drive.

I can't imagine you wouldn't be able to feel that kind of damage turning the drive by hand. Perhaps some bits not cleaned out from previous repairs? Inspect everything you can, but if the seal is intact, I rather doubt it's anything behind that.

Have had the FD apart on my '85 LTD because the pinion shaft bearing was worn, could move the pinion shaft by hand, there should be no play in the pinion shaft bearing #31 in the fiche. Took the FD apart and cleaned the inside, relatively simple job.

The bearing you mention cannot fail and have parts outside of the FD.

Check the play in the pinion shaft. Only bearing in that area that may have failed and parts are outside the FD.

Good luck.

Thanks for the replies,

The roller/needle is about 3/16" x 5/8" with no taper. I'll remove the drive shaft from the FD and see what I can find.
