i better check mine i just bought!4,000 miles and still have warranty

so the shafts undersize?or the bearings oversize?

The shaft is undersized , not a good fit but also the material is soft junk. When I get them machined and sleeved they make them size for size. The bearing has to be tapped on , where stock the Bering basically falls on.

To properly check it you need to remove the brake caliber or suspension. Get under and push up and down on the axle. You’ll know if it’s gone there should be no plan.

Haha. I know the used shaft with your gizmo will work but would be nice to have all new stuff from Yamaha just don't trust anyone around my sled.

What dealer are you talking about?, i had a nightmare from premier yamaha in sault ste marie i wouldn't let them work on my wheel barrow.

A brand new bearing is 45 mm ID = 1.77165". The journal where the bearing goes on the shaft measured 1.770" (on a brand new shaft). That means the shaft is almost .002" smaller than the bearing. NOT GOOD. IMO, every sled needs the BOP wedge! How in the world did the Cat engineers think this was going to work?!!

It is amazing that they ha d this design. I’m thinking they wanted that bearing to flex/shift ever so slightly? Not saying it’s right. I wonder if the big horsepower sleds are causing this issue more so then say 150 hp sleds? I believe that’s the case. You just don’t hear about this nearly as much on other sleds and that design has been around awhile. Correct me if I’m wrong?

My first Driveshaft was warranted also. Cross Shaft also with the tunnel.

Did you put the same cross shaft in? Or did I see somewhere that you put a heavier one in? And what is it that happens to this cross shaft? Does it bend? Just wondering as I have my skid out right now. thanks.

I used shafts from 13rr Cat for both lower center shock mount and upper front arm. If I did it again I would use the BOP shaft and reinforcements

Both shafts bend and the upper one can ruin your tunnel.

Yeah, I think the big HP sleds have this happen more. I think when we whack the throttle open, the track shaft picks up RPM so fast, it literally leaves the bearing behind. Bearing doesn't accelerate as fast as the shaft. In any case, TERRIBLE design by Cat engineering! There is no way this can work.

The bearing is suppose to move to allow for tunnel flex

Can you provide proof of this?
I find this very hard to believe. The cross shaft for suspension is mounted solid in the tunnel just aft of the driveshaft.

I had a steel cross shaft made.
