Auger sprocket

[608KEB 795]

I need to replace the auger sprocket on my snowthrower #  79360. Would some one know where I could find one? I was planning on grinding the welds on the old sprocket to get it off. I was missing a bushing on one off the idler sprockets and the chain wasn't lined up properly. It wore the teeth on the inside off the sprocket pretty good. It works fine. I've alined the chain the best I could. Maybe it will last awhile. I was afraid it would wear the chains out prematurely. Any thoughts on this?

I think you would be wise to consider replacing that auger shaft sprocket.  Mine was trashed when I got it.  I cut it off and carefully ground the shaft as best I could.  I bought a new hub sprocket from McMaster-Carr.  I had to bore out the hub to fit the shaft.  Then I cross drilled the hub in place inserted a bolt and secured it with a nut.  Much like a shear pin.  If I had a welder I would have welded it in place like the original.  The tricky part was boring out the hub.  I have a lathe, so that was easy for me.  Maybe a local machine shop would do it for you.

 

Anyway, this is what I did two years ago and Its doing just fine.

I just replaced one this fall.  the one you want is 40 teeth for number 40 chain.  It is called an A Plate sprocket.  Go to www.rollerchain4less.com.  It came with a 5/8 diameter center hole that we had to bore to 1-7/8 nominal.  Cost is $14.4.  I also bought chain and a chain breaker.  I cut off and ground off the old one and paid a welder $50 to weld it on and fix several broken welds on one of the flutes.  I also had to but the drive sprocket.  Got that from The Big Bearing Store (on line) they were the only one that had a 14 tooth, 7/8 id sprocket in stock.  The whole job ended up costing a bit over $100 and I have a piece of chain and quick links left to repair another blower

our tsc stores carry them and they have to proper inner hole,most bearing supply stores will carry them too

Just had to do mine 608 but auger sprocket was ok. Motion on the 14 tooth x 7/8 finished bore drive sprocket  $15.00 Mowparts.Com for the 18 t x 1/2 bore idlers. If needed...bout 45 for 2 with ship

 

Worn chain = quickly worn sprockets and vice versa

 

Best get going. ...sposed  to get a dandy first part of next week

Thanks for the ideas. What is the ID of the sprocket? 1 7/8ths?

I just replaced mine yesterday! Went to the local farm store and bought one that was the same dimensions! Went home, welded it on there. Now I just need a bearing for the inside of the auger chain side. Any ideas on that? Then I'll be ready for a snowstorm, which looks to be coming Tuesday!

My single stage auger shaft bearings were 1630-2RS.  Its a common bearing, any bearing house should have them or order some from USA Bearings and Belts.

 

To get the bearing out, use a long rod down the center of the auger shaft (from the opposite end).  Then tap it out with a hammer.

O.k., I finally got the new sprocket welded on the auger. When I put the bearings in. They won't spin freely. I also cleaned the auger openings with mesh cloth. Is this normal. Model 0642ST07 bearing # 1630 2RS I found the problem guys!!

Yes they are on correct. The bearing is 1630 RS2. I just ordered some from eBay. I had 2 on hand. I've put the extensions on backwards in the past too. Here's a better picture!
