Help identify model? Need a bearing I think.

Hows it going everybody, great forum so far!

New guy here, bought my first snowblower, (Well first that ive bought and kept for myself.)

Picked it up "not running" for $50, planned on getting it in good working order, and selling it for a bit more, but decided to keep it this season since it ran and worked SO well.

Its an older model, Yard-Man Snowbird, I found the ID stickers on the rear panel, where theres a model and serial, but neither bring anything up online.

Model says "31220 0 10690" But it looks like that last "1" might be an "I"
Serial: 41-008-8785

We got a few more inches last night, and I fired her up today, and the chain popped off the auger sprocket coming out of the (transmission?)

I got it back on, and realized 2 of the 4 bolts holding the front auger/shield/chute part were missing, causing the whole assembly to shift a good half inch or so, which I believe now killed the bearing in the little rod that comes out of the engine/transmission with the sprocket for the auger chain.

I ran out, got 4 new bolts and locking nuts, got them in and tight, started snowblowing again and within 20-30 seconds the chain popped off again, so I decided to tear it down bolt by bolt, got the front off, handles off, and popped the bottom cover off, and everything checks out great besides that pulley.

I will attach a couple pictures I shot after I got it running, its the little rod that comes out that has the sprocket for the auger chain. The bolts and everything are/is tight and snug, but the rod just wiggles all over, leaving the bearing to be the only culprit.

Had a few buyers lined up to buy it soon, so id like to order this part and get her going again.

Any suggestions? Thanks in advance!

If you can get the bearing out you could check the old one for a part number, or measure it and order by size. You could also take the old one to an industrial / bearing supply warehouse and they should be able to measure it and match up a new one for you.

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

Hello and welcome to the forum. That appears to be a newer replacement motor, you did well for $50. The original motor was a 3 1/2hp Tecumseh.
