Can't get driveshaft out

[Turboflash]

As we all know, in the automotive world, the rotor is fixed and the caliper floats. In these sleds with the floating rotor design, the rotor rattles around on the spline wearing out both the shaft and the rotor. IMO - BAD DESIGN. Nothing can be done now but some day in Utopialand the whole design will be changed and optimized by true design professionals to make it right. LOL

Hmmm, my rotor doesn't float , not locked solid per say but you cant move it by hand, and has 6000 miles on it.

The rotor doesn’t need to float on our snowmobiles. Its an opposed double piston design. The pistons squeeze the rotor from both sides, as the pads wear the pistons adjust further inward. Having a floating rotor can help with pulsations if the rotor has warped some, but not necessary.

Single sided piston calipers need to float the caliper or piston, or both.

The rotor does need to float on our snowmobiles because the driveshafts are not true. I locked down a rotor in testing this summer and when running on a stand you could watch the tunnel flex back and forth as the shaft was spinning. I unlocked the rotor and the tunnel flex stopped. The splines provide relief and hide the run out.

That’s another reason I like your bearing lock. It’s adjustable. I will set mine just so bearing is able to be pushed on by hand. No need to have it unmovable such as with Loctited or maybe even set screws. With flex going on in that area something has to give.

With the BDX shaft , 4 or 5 I've replaced for people it is a snug fit, dimple it and it takes some force to get bearing on shaft.

That’s because it’s made right. Probably in USA too.

I should rephrase that, many high performance automobiles have a locked in place, opposed piston caliper and locked rotor with no issues.
If everything is running true you wouldn’t need to float the rotor.

Yes I do remember you scraping the bolt/washer lockdown fix you previously were testing because of runout issues.

New driveshaft came in today. I'm impressed, I figured they'd reuse the drivers but no it comes complete ready to bolt in.
