Just been looking at XT660 Tenere videos on youtube and came across this one! Haven't a clue what he's saying, but the just of it seems to suggest that the sprocket carrier bearing sits a little too loose on the axle thus allowing sideways movement of the sprocket and carrier, could this be the cause of the cush drives early demise?
Anione understand the language or know about the mod of replacing with a more snug fitting bearing?

Don't know about the Russian mod, but fitting a double bearing to the sprocket carrier is something that several owners have done with good results. Here's one post that explains it...

Yeah, I think he's just doing it that way sound because he already had the new one in?

That double row bearing mod sounds the business!

BTW - The replacement bearing you need for the above mod is an off-the-shelf 3205-2RS (25x52x20.6 mm)

I may just do it at some point, but I'm going to see how the 525 chain fairs. Do one thing at a time etc...

Hi all interesting ideas to lengthen the life of the cush drives and it appears to improve the stiffer it is made, silicon inner tube etc. What if it was bolted ,glued or welded solid, would this be possible, some bikes do not have a cush drive. I am just thinking out allowed really. Steve.

I think all that would do is move the wear (stresses and strains) somewhere else less easy to fix, like the gearbox. At least with the cush rubbers (a throw-away item) and sprocket carrier bearing being the weakest links in the chain, so to speak (no pun intended), they are cheap, quick and easy to fix.

I have had a look at this problem and I also think that it is possible to machine out the casting to twice its depth and put two bearings side by side. Thus keeping standard bearings and giving more support to stop the hub from wobbling. That's what I'm gonna do when I next have the wheel out.:098:
