We have a '94 R-62, did the same bearing, shaft as you have. (Actually our maachine was a dud until we sorted out a lot of problems, took a couple of seasons but now we keep going without to many hiccups.) Unsure what shaft the dealer put in, but 3 seasons on and no trouble since. Trick is to tension it correctly upon installation - 4 feet of pipe, 2 blokes and give it every thing!!!!!!! No worries. Happy harvesting, Silver Aussie.
