How do I replace the auger assembly on my Craftsman snow thrower model 536.886261?

Mark T. you left out one critical step, in the auger removal procedure. The bearing pressed on the center shaft does not fit through the hole in the housing (#500), so I had to pull the bearing (#491) to get the center shaft out. Everything else worked fine, I have the damaged gear out and I have ordered the new part.

However, putting it back together there are going to be 2 problems:

1. If I try to press/hammer the bearing onto the shaft while the unit is assembled, I am afraid that I may damage the gearbox. Can I drill out the housing (#500) center shaft hole, to make it big enough to fit the bearing through the hole?

2. With the auger in place, the impeller completely blocks all access to the bolt heads (#493). So how do I tighten these bolts? The only option I see is to pre-weld the bolts in place before assembly.

The input bearing is not a press fit. The bearing should just slide onto the shaft. If the shaft were rusty, you would have had problems removing it. I recommend that you clean the shaft with emery cloth to aid in the reassembly of the bearing. The bearing should slide onto the shaft but not be sloppy. Also make sure to use anti seize on the shaft. The impeller should have holes in it that will line up with the bolt holes for the bearing. Use a socket to hold the bolts as you tighten the nuts. Please resubmit your question if you need further assistance.
