Picked up this old girl late last Fall to use as a groomer donkey. Great shape, but it was making funny sounds in the drivetrain and finally at the end of the season it started leaking gearbox oil. I feared that the gearbox had failed and she was headed for the scrap heap.
Tore into it yesterday and removed the rear skid, driveaxle and gearbox... Found the grinding sound, driveaxle brg on the throttle side was gone gone and seized in the holder.
Got it on the bench and it appears that the shaft was spinning inside the inner race and the shaft is worn down: should be 25mm, is more like 23mm at shoulder and 21mm at the end of the shaft. Crap. There are no machine shops here that can practically build up the shaft again, that would require a significant investment.
Not sure what my options are but I mocked things up with electrical tape to center the brg half decent tonight and I'm contemplating welding the brg on, being careful with heat. Hardest part would be that the brg has to go on the shaft after it's in the chassis (because of brg holder assembly sequence) so I can't weld it on the bench. Not sure what I'm going to do there.
Welding is semi-permanent but I'm not sure what else I can do to get this thing back moving without a significant investment. Any ideas?
