Good Morning, still using a stirrer and works well for me. However lately have a problem with the chain. First it developed a kink because I think it bacame too loose and hit the sprocket. Fixed that by bending back and forth and soaking in oil. That being said, lately I watch the chain and notice it keeps getting looser and looser. So I retighten the gearbox bolts. They seem to have a rubber washer on them also. I try not to overtighten. I was wondering if I could do what I did with my Auger Gearbox and drill out the tapped screws and make it a through hold and use a longer screw and washer and nut. I wonder if I should do that. Another idea was to use a shim in the slots to keep the gearblx from sliding. Any ideas? Thanks. PS--I noted in my Phamphlet the sprocket says 11 teeth, but I only count 10, is that a misprint? Can I go to a Bike shop and get another chain if I need it?

The rubber washers help keep the transmitted noise down.
In our family room the stirrer noise was quite loud before
installing the washers.
I don't see any reason why you could not use the thru bolt.
Double check you stirrer rotation. It should be very
free to turn. We use never seize on the shaft and bushings.
Hope you get it fixed.

Thanks. Been watching since retightened the chain and seems to be OK for now. If it loosens up will work on it then. Summer project. Also the rod type bolts I did on the Auger motor works well. A lot easier to take off the gearcase. I don't see why they don't do that on OEM. But I suppose they assemble the inside before the sheet metal and is easier to get at at assembly. Learn a little every day. I have a scrapped exhaust motor assembly and am working on how to cut the sheet metal, be able to remove the motor and fan, then make a ring to reassemble. Another pie in the sky project. If it works then will be able to take out the motor and fan without removing the entire assembly to clean behind the fan.

Let us know if you get the fan project done!!
Several of us would like to do the same thing.
