I got a free Husky/MTD 30" 9HP snow blower with a broken reducer gear. I have it replaced, but now I can't get the impeller shaft through the bushing in the housing. I've tried putting a 2x4 on the new reducer gear and hitting it with a maul, but no luck. I can't take the bushing out because the bolts will be covered by the impeller when it's all set in place.

If I can't get this in, do you think someone would buy the remaining part of the blower? It runs fine, but I can't take up space in the garage anymore. Too much snow!

Have you try polishing down the shaft and inner race of the bushing, sometimes dirt and oxidation expand the surfaces?

Anytime I mount anything with a friction or interference fit I try to achieve a temperature difference between the two items. So, heat one and cool the other whenever possible.

+1; heat the bushing & cool the shaft.


If there were set screws...they often mar the shaft; you may need to sand/file-down the marring.

good luck!

Thanks for the quick replies everyone. I will try to clean/grind the shaft and bushing, then heat it up. Fingers crossed (after I do the grinding).
