Re: John Deere 400: snowthrower bearing trouble
The driveshaft axle goes all the way through the auger. Have you loosened the eccentric collar on the inner bearing race? You'll need to loosen both collars and slide the shaft over. IIRC when I replaced the bearings, I made sure that the bearing plates were reinstalled from the outside to make future bearing replacement easier. I may not be remembering correctly, though.
