did you remove the allen head set screws on the collars? they can be a pain as they like to rust in the collars. normally there are 2 per driver.

 

I'm working on the left side (clutch side) & I have loosened the set screw on the collar next to the outer wheel. There is only one collar and that is on the inside of the outter wheel. I can't move the collar nor the outer wheel.
Any Idea's on how to free it?

Do I need to remove the right side collars also or is there enough room to just do the left side? Like my polaris.

 

i havent done one of those sleds in quite awhile, but it seems as though both collars need to be loosened and it is still a tight fit when removing the shaft. you do have the chaincase removed, and the bearing behind the speedo cover slides freely?

 

Some bearings have an eccentric locking collar; the collar locks onto the bearing's inner race. You have to loosen the set screws and turn the collar to unlock it. If that is what you have, you will find holes on the outside of the collar, use a punch in the hole at an angle to tap the collar and turn/unlock it.

 

I have the gear case taken apart & the set screw on the collar left inner side apart. The shaft is in an hexagon shape. There is a small hole beside the set screw. Not sure if the collor will turn. I tried to pry the collar and the wheel apart, want move.
Anyone have any other advise. I'm at a lose. More snow is comming

 

I think you have the eccentric lock collar. See link for an explanation of how it works. NTN BEARING CORPORATION OF AMERICA - Eccentric Locking Collar Mounting

 

Thank you for every ones help. It did not have a eccentric lock collar. I borrowed a hydraulic splitter for extra leverage. The collar on the left side was frozen. I put the splitter on the right side of the frame & pried against the wheel on the right side & the collar on the left side potted free. So easy!!!!!!

 

Nice to hear you got it off.
