Not on mine yet but 2 of my friends had this done at the same place and it worked great over last winter (about 2500 miles). Just a week ago, we used the BOP puller to remove bearing. Had to heat it up because we had used green loctite when we assembled it. It was still tight on shaft (interference fit), shaft looked exactly same as when we put it together, no wear or flaking, etc. If done correctly, spray welding works. The shaft was ground on centers after spray welding to provide a .0002-.0003" interference fit to bearing per ISO specs for this size bearing. If you do this, remember to use a C3 fit bearing so as not to introduce radial preload into the bearing when you press it on.Do you have any miles yet with the shaft spray welded? I decided to go one step up and have the winder shaft chrome plated, its harder than a weld and I was told by more than a few people that spray welding is prone to flaking. Fit is very tight with a new SKF bearing, I have to heat the inner race of the bearing to slip it on the shaft. This may bring on some headaches and I will find that out soon but once together I wont be worrying about it.
