How do I remove an impeller shaft from the flange bearing assembly on a Craftsman snow blower?

by Manage My Life Last activity date:

I have a Craftsman Snow Blower model #917.881151. I need to remove the impeller shaft from the flange bearing assembly. I already pulled the pulley. That was simple, but the impeller shaft seems to be pressed into the bearing. How do I remove the impeller shaft with out messing anything up?

First you need to remove the pulley with a pulley puller. Place a 5/16 -18 screw in the impeller shaft so you don’t mess up the threads. This will give you access to the flange bearing assembly. Use the pulley puller to remove the bearings housing as well as the bearing itself from the impeller shaft. Once every thing is off the shaft you need to remove the screws that hold the augers to the auger housing and slide the entire auger and impeller assembly out of the auger housing. Use some #0 steel wool to clean up the bearing, the pulley and the impeller shaft before putting everything back together. Use a deep socket that fits over the impeller shaft but not over the bearing and press it back onto the shaft with a dead blow mallet. Use the mallet to press on the pulley as well or a

5/16-18 X 1.5" bolt and a deep socket. Being careful not to strip the threads or break the bolt off in the impeller shaft.

The flange bearing is not pressed onto the impeller shaft. I must assume that you have taken both gear box housings (key# 41&47) apart first or you're not going to be able to pull the impeller shaft out. You must separate the gear box in order to raise the shaft up over the worm gear (key#45) before you slide the impeller shaft (key#36) out of the gear box. See image below.
