Impeller shaft play ST824

Hi Guys,

On my 924050 with the aluminum gearcase how much play should there be in the impeller shaft fore and aft. I'm just wondering if the thrust bearing is wearing out. I have about 1/2".

Thanks.

Really shouldn't have any. There is a collar on the bushings that prevent that. Now might be a good time to open up the gearbox anyway as the grease in the aluminum ones can harden and dry out over time. When I opened mine up I wedged a washer between the bushing and the gearcase to push it tighter against the impeller shaft. In my case, the old grease still looked like new, but I replaced it anyway as I had it open.

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

I agree! A few thousandths or tens of thousandths okay, 1/2" not so much.

~1994 Ariens 924084 (ST1032) "papa bear": restored, re-engined, real nice!
1991 Ariens 924050 (ST824) "mama bear"
Toro PowerCurve 1800 "baby bear"

Be alert! America needs more lerts.

Pulled most of it apart. The bushings in the gearbox are gone but the gears/shaft look good. Definitely found the source of all the play.

If I could just get the impeller off now...
