I have not had this apart yet and needed some direction.

When you have the new bearing pressed on the 'clutch side jack shaft', and go to slide it across into the chaincase. What are guys using as a bearing driver to place the new bearing in the housing?

There are videos of this for 800's and 1100's but little mentioned for Vipers or SW.

Does this bearing just slide in with some heat, or does it need to be driven in with a specialty driver? If yes, who sells them?

Thanks

I use heat to remove it and then I put the jack-shaft in the freezer and put the slightest bit of heat on the inner race and drop it right on.

As far as getting the bearing into the housing on the clutch side, same deal, heat up the out side and it will drop right in.

That because it's the same setup on all these sleds....

Those bearings had the wobble bearing with a threaded collar with a locking ring. Our sleds don't have that. On the yamahas, the jack shaft bearing (already pressed onto the jack shaft) just slid into the housing on the clutch side. I am not sure whether things fit that easy on these procross sleds.

On my Nytro, it just slid into the housing. No need for a bearing driver of some kind on the procross sleds?

So I guess some kind of driver needs to be jury rigged. Heavy washers with a pipe to fit around the jackshaft could work. I have seen videos of a specialty tool that does this but I cant seem to find it anywhere when searching.
Any ideas.

I to have replace mine and was wondering the same thing. When my buddy did his he actually took the clutch side housing completely off and used a press to get the old one out and install the new bearing. I didn’t like this because press put a lot of pressure on the housing and you could see it flexing. I saw a video on line where a guy working on a CAT heat the top side bearing in chaincase with heat gun for 2 mins then used a slide hammer to pop the bearing out. The new bearing he put in the freezer for a while and it just slid in. Would be cool if one of you guys could detail procedure in sticky help section. That way people like me stand a chance!

Trust me I have done many and a little heat goes a long way. No need to beat on anything.

Great idea but I dont have one to work on to make the video at the moment but the next one I do will try to remember.
 
Personally i put the pto bearing on the shaft first. Shaft and bearing in the freezer or outside in the cold. Apply heat on the brace bearing assy. Slide shaft few taps and it’s done.

You can also drop the bearing in a fryer for a few minutes then pull it out and should slide right on, we do it a work all the time way better than beating on the bearings.

On the other hand just got to thinking not sure if it's a sealed bearing or not if it is probably can't do that.

I usually cook eggs with my bearings :)
