Barn of Parts New Driveshaft Solution

[74Nitro]

I still think even with this design the wear in shaft should be addressed either with shim,welding or maybe even Epoxy. The load on bearing is not going to be centered under the bearing. Kind of like a offset rim can be hard on a bearing. It would be ideal if the brake hub could be machined narrower at back and collar extended and splined. Would not need the set screws at that point and sleeve would have support at both sides of bearing if fit was good. Probably cost prohibitive though. Hope this proves successful.

I think it will be fine.
I can't see how it's any different than bearings that have set screw collars on one side

Because the shaft isn’t wore out under them. You are probably right though.

Does anyone make a completely new shaft with better tolerances? Years ago there was a tool company in Connecticut that made better shafts for our Thundercats that did not twist or break. They worked great. Perhaps the best solution is a better shaft with a matching high quality bearing that has a better fit.

Stock seal is 45x65x8. Collar was spec'd to 54mm OD as you can get a 54x65x8 seal.

Let me know how it works out for you. I could likely make a custom one for you that has a key way slip fit between bearing and collar if needed.

IMO, if someone is going to make a new shaft from scratch for this application, then they may as well just make it so bearing presses on. Problem solved.

If you are going with a new shaft, then the original part plus the BOP driveshaft saver is a proven, easy, off the shelf solution.

Sorry, I thought you were talking about on a good shaft.
I'm not sure if it would be an issue on worn shaft.

Not sure if this is the best thread for this question - but I'm hoping to get at my sled this weekend to pull the shocks for rebuild.

I won't have a lot of time but is there a quicker way to check is the driveshaft is worn? I'm assuming I'd need to get the bearing accessible and check for movement. I've changed these bearings out on a Polaris but not yet on a procross so I'm not that familiar with that part of it.

I would not install on a worn shaft .

This is specifically made for a worn shaft INBOARD of the original inner race is where the collar is locked down with 3 set screws.He has a great video on his website

So now your relying on 3 set screws ? Good luck

And the interference fit of the collar to the inner race of the bearing.Ride on
