"I have a White snowblower, model, White Outdoor 31AE5E3F190 Snow Boss 950W (1999).

The left spiral rubs against the blower housing. I suspect that the outer bearing where the end of the shaft is against the left side of the blower housing is trashed and is allowing it to move about.

I must pull the two spirals with attached gearbox and shaft out to replace the left bearing.

The shaft goes into the impeller with two spiral pins. If I manage to knock these back out (it appears that I should push them out to the right when horizontal so that the longer end protruding moves out first) will the shaft that drives the spirals simply pull out? It’s difficult to see looking at the schematics:

Model 31AE5E3F190, Serial Number: 1J068B70370 in case links are not allowed, I found schematics at partstree com

I cannot tell if the end of the shaft is splined or not and how it fits into the impeller and how to remove the impellor with the shaft and spirals. I had hoped that the impeller with shaft/gearbox and spirals would come out if the end bolts were removed but this did not work.

It seems like an easy fix (if I can get the assembly out) since the gear is not broken and the right spiral is tight, but the left wiggles around by about 1/8” inch. I can’t imagine anything other than a damaged bearing at the end and the bearing is available for ~$25.

Suggestions? I have tried to tap out the spiral pins but it’s been no go yet. I’ll try heat and pound but only if the shaft, once the pins are out is likely to pull out. It’d be a very expensive fix should I have someone else do it at $60/hour. Since I only have a part-time job, I’ve got the time on my hands." It seems like there should be a spiral pin remover like a gear remover available but maybe not.

Thanks for any suggestions.

Welcome to the forum Jsflynn :D
Please add a location to your profile so it pops up under your user name.

It's just a roll pin part #17 on the diagram and should be able to be pushed out using a punch or even a sturdy nail. If you remove them the impeller should be free of the shaft but normally you pull the augers, gearbox and impeller all in one part.

You need to remove the pulley on the back of the shaft behind the impeller that the drive belt rides on. Remove bolt #6 in this diagram to slid impeller shaft through the bearing in the housing and the auger assembly out the front of the auger housing.

Yea, don't bother with the pins holding the impeller inside the drum part. You have to split the blower off of the tractor section, remove the large pulley for the belt and then slide the whole assembly forward. That shaft going straight back goes all the way through to the drive belt.

While you have it apart it is probably a good idea to replace the bearing behind the impeller as well.

Make sure the spirals are not seized to their shafts with rust. Remove the shear bolt and see if they spin.

Might want to change out the grease in the front gear case as well.
