I own a Craftsman push mower, model 917.387460, which I bought in 2004. One of the wheels has cracked, and needs replacing. The Craftsman wheel I bought from Sears turned out to be a) too large, and b) redesigned in such a way that I can't tighten the nut all the way - and so when the wheel rolls, it catches on the nut and locks it up! I went to the Sears website, and that was no help whatsoever. The person I chatted with insisted that the substituted part was a "functional replacement part" even after I explained that it clearly wasn't. His suggestion was to change out the wheel assembly - which of course ignores the fact that the wheel is the wrong size, and to replace one wheel I'd wind up changing all four wheels plus the assemblies!
Any advise on how I can track down the actual "vintage" replacement part?
