42" single stage snowblower refurbish

Recommended Posts

Anyone aware of any videos showing teardown of a 42" single stage blower? I'm going to replace the bearings in mine and wondering if its straight forward? Any good source for the new bearings?? Thx.

Replacing bearings is straight forward (you'll probably need a puller), but IMO it helps to have the tool that tightens/loosens the bearing eccentric collar:

It was much easier using this than a punch and hammer, especially in tight spaces.  

Here's a series of pics I took when changed out bearings:

The drive sprocket came off pretty easily:

To stop the auger from turning when using the puller I used some plywood :

But the chain side

bearing didn't want to come off:

Please let me know if you have the same issue.

I'm assuming the bearings on either end of the auger are the same?? You say sprocket came off OK but chain side bearing was stuck. Is it safe to assume the bearing on the other side of the auger wasn't stuck?

Bearings are the same.

I don't remember the non-chain side being an issue.

Got the bearings and attempted tear down. Got sprocket off with a gear puller but it's not going to grab the bearing so..... Have to see if I can get a pry bar behind the bearing and pound it off or get a bonafied bearing puller. Might also just grind the gear puller jaws down so they form a 90 degree grabbing surface. I still have to address getting the collars off. Might have to find that collar removal spanner. Where did you get yours?
