I have never seen a Guzzi u-joint that showed no evidence of spinning
in the carrier bearing. Never. Some show more evidence than others, as
John said. I've seen them actually blued from the heat. Since it's what
I have, I'm using blue loctite (I have none of the green bearing
retainer). I still think red loctite is too strong a bond, based on my
little experiment.

It really took the yoke OD down to an unacceptable diameter. This may have occurred because the carrier bearing siezed, not sure. As for me and my u joints - we're going loctite!

But, on the even days of the week, I think its a good idea to take some pre-emptive measures. I think the real issue is that the fitment of the U-joint to the carrier bearing is not precise. Sometimes the fit is tight, more often it is a little loose. Add to that the fact that dissassembled u-joint/carrier bearings show signs that the u-joint and carrier bearing were spinning at least somewhat independently. Solutions have included some form of loctite, knurling, or center-punching the u-joint (and probably others). In the end, I'm not sure it's worth the trouble given that a replacement carrier bearing is easily obtainable and relatively inexpensive. I also don't know that it does any terrible damage to the U-joint itself. All that being said, I used blue loctite on the mating surfaces when I replaced the carrier bearing in my Quota last fall. If I were you, I think I'd just run it and worry about it later when you need to remove the swing arm for some other reason. As for the direction in which to install the U-joint, I think you can usually tell where the bearing was originally installed. I'm not sure it matters on many u-joints, but I think perhaps some weren't machined to accept a carrier bearing on one end. I just don't know. tom short wrote:
