This is a repost of a post that I added to a rather long existing thread.
NEW DAY NEW PROBLEM…..oK people….I got the lower shaft and bearings out. Progress??? Not necessarily. The bearing on the pulley end came off the shaft with no problem. The bearing on the wheel end (opposite the pulley) slides about half way over the threads and will not come any further. I looked at the threads on the end of the shaft with a magnifying glass and noticed that the threads are about half flattened. There are some severe marks on the outside of the bearing that looks like the PO put those bearings on with a punch or something like that. I could probably drive the bearing off the shaft but will no doubt do serious damage to the threads on the shaft. Or I can attempt to break the bearing apart some how and remove it in pieces.
I did notice that these bearings appear to have been replaced. They are stamped “Japan” with a number that I can’t read. The upper bearings were original with the correct part numbers.
I did notice that when I removed the nut on the wheel end of the shaft that I had to turn it off with a wrench all the way to the end. Either way the threads are damaged. If they were a normal thread there would be no problem. I would simply run a die over the threads and clean them up. These are fine threads and I don’t know anyone who has one of those.
