Jack shaft SW

I didnt remove my inner case either. Will be next time. Just check all bolts holding it in then.
Koyo 6206 is what both my Viper shafts have clutch side Jackshaft.

Sorry. I have only changed whole assembly but bearing says 6206 right on it and parts fische says 6206. Who knows with Cat involved. All I can suggest is order a new one from dealer and let us know what you get.
 
  1. That's what i did, they had one in stock which is miraculous. haha. 6206 "standard" 30mm id is the one in the chaincase the one behind the drive-in is 6206RD 28mm id only available at the dealer. That's the answer i got in 2 different bearings place. At least it's a KOYO(made in japan) 50$ ...lol
