QA36A snow thrower on a IH 147
I had the same problem putting a QA36A on my IH 147. The belt was rubbing on the left side as you look at the tractor from the front.
On my snow thrower the bar that the whole thing pivots on is 2 5/16 longer then the bracket. I was going to put a piece of pvc pipe on there for a spacer or bushing, but thought it might be to ridged and maybe crack a weld under the stress of operation. So as I was walking into the shop I spotted an old washing machine drain hose. You know the one that has a u shape at the top. I wacked 2 5/16 off of it. That gave just enough, and I mean just enough space to operate without rubbing, Its hard to see in the photo's but there is about 1/8 of an inch in there for clearance.
The manual mentions some sort of adapter for machines with serial numbers under 400,000 or some crazy number, maybe this is it! Good luck.
