New top gear & Drive axle on 2022 sidewinders

[jonlafon1]

I just shake my head after I pulled it apart. I was all excited to take pictures and post up better clearance. Actually the clearance was horrible. Like I can slide the bearing on and off shaft without the anti seize the factory put on it. At least my last one it would stick slightly and you had to push it on some. This one the bearing just slides on and off like nothing. I put a better bearing in and bolted the brake half back on. I split the brake as I find it easier then leaving brake line attached.

Country Cat shows the 3602-321 shaft on 2022 models.
The shaft i have is a 2602-740 part number.

Interesting. So I got me a yamacat. Sounds like they gathered all the parts laying around and built some winders? Wedge at 45 pounds and hope for the best. I’m going to use wicking thread locker on this one. Pull it on it side and drop a few drops in. Then tighten wedge. Then another 2-4 drops and let it wick in.

The shaft and bearing don’t have a chance from the factory. It’s loaded with anti seize for sh$@s sake.

 

[Turboflash]

That’s why I checked it. And the cheap China peer bearing needed to go. It’s like nothing I ever seen. The factory is making things worse. Way worse

Does the driveshaft saver fit the new shaft? The added hardness could hinder the ability to expand the shaft. Let us know how it works out.

When I heard that the shaft was harder, I began looking at possible ways to improve the driveshaft saver to make if more effective if need be. If I make the fingers thinner then there is less resistance in the tool itself to overcome. This could yield more expansion power to overcome the tougher shaft.

So now we might have parts in a Yamaha with cat part numbers? I realize they are the SAME parts but?..

What is so bad about the Peer, a SKF company, bearing? 6500 miles and my bearing was fine. Just spun.
New shaft in 2020, new bearing, BOP wedge began to lock at 20ftlbs, clicked it to 40ftlbs, and done.
Did this on both sleds.
If the new 2020 shaft was machined any tighter it would have been a press fit.
You're saying the 2021 shafts are machined loose?
It's not the bearings fault if the mfg can't machine to spec.

I have not tried it on this one yet. I have a wedge in my 2021 Cat and that was a tight fit on the 21 shaft. My plan was to pull that one and use it on my sled.. Long story but I have not tried yet.

the SEAL is garbage on the peer!

This is a 2022 sled that suppose to have a different drive axle in it. Its supposedly harder. Mine had terrible clearance, and was loaded up with anti seize from the factory new.

 

[Phatboyc]

Its not anti seize. What your seeing is a red neck fluid bearing.

The fact that they're using anti-seize at the factory lends credence to the theory the engineers don't want the bearing locked to the shaft and exposed to axial forces from the chassis flexing. Not sure if those locking it down are experiencing early bearing failure. but from personal experience years ago I learned to never lock down the pto side driveshaft bearing until the skid is mounted in the tunnel and braapped on a few times. Evidently they feel the shaft is just a wear item. That thrown out there, I'm about to tear mine down for a track change with 863 miles and it's getting a new BDX shaft and drivers with SKF bearings packed with Redline CV-2. Curious how the tolerances will compare to the factory setup.

I could see "wear items" being things like slides and wheels in the skid.. BUT a shaft is not a easy wear item to replace. And if its not back ordered its slightly pricey. I understand what your saying though.
