M2 clean grain auger drive sprocket

Bushings have worn out on my clean grain auger sprocket (lower left of machine)- caused the sprocket to wobble and throw the chain off. Also broke a chunk out of the back half of the slip clutch. Noticed the teeth on the sprocket are badly worn, too. I have a replacement clutch part, but not a sprocket.If I understand the online parts book right, an M used a 32 tooth sprocket, and the M2 a 35 tooth. I have access to an M parts machine nearby. Wondering if that sprocket will work. Anyone know or have an opinion? May see if a local machine shop can press in a new bushing on the old sprocket just to get these beans finished.
 
Should work if e erything matches up. Be aware it will reduce the capacity of the elevator a little. Ben
 
I don't know, but you opened it up to opinions! I assume the clutch jaws are the same between those machines you mention. As long as they fit, I also assume the shaft/bushing size is the same. So the only thing they changed was the tooth size of the sprocket. This is a driven sprocket, so as it gets bigger, the auger/elevator turns slower, and vice versa.
 
Clutch jaws are the same. In fact, I have that part already from my E3 parts barrel. The E used those, too. Shaft size is the same, and you confirmed what I was thinking about sprocket size - smaller diameter driven speeds things up, larger slows it down, and just the opposite if it's a drive sprocket.
 
Would guess it would work fine for beans, would be trouble for keeping up with modern corn yields.

TLC Machine shop made me a bushing and pressed it in. Put sprocket back on with replacement clutch half and ran great for an hour - 'til my right rear tire went flat and wadded up around the rim. Stole one off an old auger wagon and finished field I was in. Moved to other farm and ran until I started losing rpm's and it finally died. Loosened fuel cap and "whoosh" - fuel cap vent must have plugged with soybean fuzz. Bled the old gal and she's going strong - ready for tomorrow. Thanks for the opinions/advice on the sprocket.
