Gilson 10/32 monster: question for Spectrum on auger scars

This is a quick question for Spectrum on this last generation 10/32 Gilson made Lawn Boy snowblower.

In the enclosed pictures, you will see scaring on the exterior backside of the bucket - not scaring on the inside. By scaring, I mean the emergence of these faint rust-type lines which appear as if the auger is flowing around in its rotations and thus is scraping against the inside of the bucket. This is prevalent in many type of old, used machines - regardless of the manufacturer.

Why exactly is happening here - are the auger bearings worn out or is it something to do with something inside the auger gear case being worn and thus out of wack?

I'm pretty sure if you look carefully inside you will see where stones have been bitten by the auger and carried around the The steel has been slightly dented outward cracking the paint and inviting rust. I have a crushed gravel driveway and see this happen from time to time.

On that 32" model you do want to watch the auger bearings. Those sintered bearings have been known to fail when loaded up by things like those stones. I have one that had the bearings fail and when it all went wild it took out the worm drive housing. The 6061 aluminum replacements I offer have done fine in all applications. The bucket cutouts do not accept the old school cast iron ball and socket bearings.

That can happen with almost any brand of blower if the engine has enough power to keep it running with something like a rock going through the auger and getting between the auger rakes and the housing. It shouldn't hurt performance but it is an eye sore and it is fixable if desired.


Rebuilt a Craftsman that had that problem, the housing had big enough dents your could see and feel them on the outside. Probably stuck out 1/16" - 1/8" overall. I used a body hammer and curved dollies like would be used for auto repair to fix them (there were multiple ones). Disassembled the housing, dolly on the inside and slowly and carefully hammered it on the outside and got the dents removed. Abrasive blasted it due to rust, primed and repainted it and came out great.


Check your auger bearings too. That one was damaged so I converted it to roller bearings at the same time.


Hope that helps.
