I bought a new tiller shaft and bearings for my Troy-bilt horse. I accidentally scored the shaft while replacing an oil seal. I bought an aftermarket shaft on ebay (made in USA) and it is the exact same size as my old shaft. I also bought new bearings from Autozone using the numbers stamped into the old bearings. The new bearings do not fit tight on the new shaft, there is just enough slop where the bearing spins. I was told to use Loctite bearing mount #8531. Looks like that product is discontinued. A quick google search leads me to Loctite bearing mount #680. I have never had a bearing that didn't fit tight on the shaft so this is all new to me. Does anyone know if this Loctite product is the answer to my loose bearing? I am only looking at a few thousandths at the most to make this bearing fit tight on the shaft. Any suggestions are appreciated.
