Craftsman 29" - Can't remove shaft

Trying to change my augers. To do that, I've removed the auger housing, and the belt pulley. I'm trying to pull the entire auger unit (shaft, impeller, gear case, and augers) from the housing through the ball bearing retainer. It slides freely until the aft end of the shaft is flush with the ball bearing. Then it stops. I've pulled with all my might but can't get the shaft through. The fact that it stops so abruptly after easily sliding the first 3 inches leads me to believe that the shaft is slightly flared or damaged. Could I be missing something?

The snow thrower is a 29" 2-stage Craftsman 9HP, model 536.887990.

Thanks.

Just take a file or a grinder to the edge of that shaft. If you use a power tool be careful not to take too much.

Please direct all snow blower questions to the forums and not to me with PMs.

Just tried that, but I am getting the same exact result. The shaft slides until the end reaches the bearing, then there's a clicking sound and it stops. I've got to be missing something.

I'll post pictures in a few.

Sorry for the file size. I probably shouldn't have unfastened the bearing case, but I needed leverage without having to pull on the auger shaft and gear case. In the second photo, one can see where the shaft stops. The fact that there is an audible clicking sound leads me to believe that I'm missing something.

It's gotta be the end of the shaft. Try a flat file all around the shaft one more time. There should be a mark where the bearing stops on the shaft.

Thanks. I gave up and took it to the pros. A service guy told me that sometimes the shaft needs to be heated up to be able to remove it.

I think I can actually see the burr in your pictures.

If you heat the shaft, wouldn't that expand the shaft? I've been putting on, and taking off bearings, and other things on shafts for nearly 60 years.
