I'm working on taking the drive axle off one of my 800 to upgrase Jackshaft, clutch's on 93. On the spedo side it was pretty rusted and I had a hard time getting the nut off, but after letting soak in a little PB Blaster it came off. Now spedo bearing is rusted into shaft. I don't care about bearing, but don't want to damage shaft. Any of you experts have any good techniques to get this off? I have soaked for a day w/ PB Blaster and still seams stuck. Thanks for any help!
