I have the drive on my sno-caster all apart I'm talking about from the gear box to the sprocket... I have the sprocket off,,, But the bearing,, # 1185898 is about seized on the shaft... ( Doc,, you have those.?? )
I'm trying not to destroy it in case I have to bring it into a local bearing shop.. 2 nd,, it appears to be in a cast housing ,, Is it pressed in the housing.???...Or doe's it only come out one way.?? 3rd There is a collar on the back side of that.. I have the allen screws out and it will not budge either.. The parts manual doesn't even show it being there,but looks like it is there to keep the bearing and collar tight to the side of the caster body.. which there are 2 carrige bolts holding it to the body..I've been soaking it for a few days now and today I think I'll add a little heat to it..
The bearing is a self-aligning bearing, and that collar is part of the bearing assy. .....The purpose of that collar is to lock the bearing to the shaft.
The collar is actually eccentric on the I.D. , and when turned against the extended part of the inner race of the bearing, creates the lock.
To remove the bearing, after you have removed the set screws from the collar, try rotating the collar in either direction while holding the shaft stationary with a vise-grips or pipe wrench. (Most times it will take some effort to unlock the collar.)
Rotating the collar in one direction will loosen the collar, while rotating in the other direction will lock the collar.
You should not have to buy the bearing and the flange as an assembly. .....Once the flange is removed from the blower, the bearing "swivels" in the flange and can be removed from the flange.
The new bearing may, or may not, come with a new collar. ......The self-aligning bearing has rounded "corners" on its outer race to allow the self-aligning movement in the flange.
Usually, the self-aligning bearing carries a "U" prefix, such as U-216. ....The numbers vary depending on the size of the bearing.
The bearing is similar to the self-aligning bearing on the main clutch shaft of the tube-frame tractors, but I am not sure if it is the same size.
