M500 Driven (Jack Shaft) Sheave Adjustment or New Part

[suffusive]

After you have removed the primary drive chain…….both shafts will (should) pivot about 60 degrees in any direction. If they will not, your bearings are frozen into the housing……you probably will need to replace both bearings. I have seen many of these bearings replaced with the incorrect bearing housing……..when tightened it presses the bearing against the sidewall and does not allow free movement of the bearing itself. Let me know if you need a part #…….much cheaper from a bearing and chain house than dealer.

Damn, I had a feeling I wasn't going to get out of this without opening up that other side!!!!! That's ok, it would probably be a good idea to have a look in there and see how everything is doing. If one side of the shaft was bent I'm sure that other bearing is toast anyway.

I've ordered bearings from LoaderPartsSource.com, they say it will fit:

Be sure to check the clutch linings while you're there…..if they need to be replaced, now is the time to do it.

Well, 11 years into the replacement driven sheave and it's all wonky again. What is going on here? Video link:
