Simplicity 1691898 Belt Smoking

Hey guys, I had to help my dad with his old simplicity 1691898 .. it's been amazing however last year the belt came off the pulley that turned the auger .. he said a rock hit it.

Him and I put it back on - the original belt. Once we started running it the belt started to smoke and little pieces were flying off.

I am totally stumped as to why it's doing this.

When we were working on the machine the parts I had to touch were the throttle (which took a little trial and error to get back the right way), I loosened the tensioner to put the belt on, and that's it.

So far I've lubed up everything, adjusted the pulley many times, even adjusted the tensioner rod that goes all the way back to where your feet are. I can't seem to figure out why it's smoking. It smoke's once it's engaged.

I would love to fix this!

A Rock May be jamming the impeller. Try to move the impeller by hand. If it is stuck, Put a 2x4 into the chute resting on an impeller Blade. Hit 2x4 with Large Hammer to Free it up.

Hey ... so I can move the impeller by hand. I learned from my dad that the cause of the original belt coming off was that he hit a rock with the auger. He said at that time even the auger shaft popped out .. and he had to pop it back in. That's also when the belt came off.

right now everything is put back together and there are no rocks ... we are thinking maybe there is a shaft that is bent which is causing the pulley to be harder to spin maybe?

How easy should the impeller be to rotate?

Should spin Fairly Easily if brake is "off"and belt is removed. It will need disassembly to determine the extent of the damage. Most Likely Won't be a Cheap Fix.

Ok makes sense ...

Last thing I can think of is that when the tensioner engages ... it sort of "bounces" back and forth ... is that normal? Or should it be operating almost as if its in a fixed positions and smooth?

The problem might be that the belt is running on the wrong side of the brake lever. If the belt was completely off and you reinstalled it without being able to see the brake lever, then if could have ended up on the backside of the lever so that when you engage the auger clutch, the you are forcing the brake lever against the belt and that will chew it up and cause smoke. You might have to remove the bolts holding the auger housing to the tractor and let the auger drop away a bit on the bottom pivots to see whats going on there.

Could also be that the belt is not routed properly under the belt stops. Heres a link to a manual to so you can see what its supposed to look like.

Plan on getting a new belt in any case.

Work fascinates me.

I would guess it might be the belt routed over a belt guide or the belt stop like skutflut mentions above. The guides are just fingers that keep the belt in position when the tensioner is relaxed and the stop actually comes in contact with the bottom pulley over the top of the belt to stop the rotation of the impeller/augers.

It's routed properly and clearing all the guides.

As i mentioned earlier .. it does "bounce" the tensioner back and forth a little when it's engaged which makes me think maybe the brake is hitting it? I'm not sure if a bounce is expected behavior or not or if that tensioner is supposed to remain stationary and fixed when engaged.
