I bought a used ymf80 for my little girl a week ago and thought I got a good deal. But after 3 hours of riding, I started to hear a clicking sound from the rear. It got worse the more she rode until it got to the point where it would not go. So I get a manual and start taking apart the rear axle. It does look like the drive pinion is worn badly.

So I figure I better get it out before I order a new one. I got the nut off that holds in the first bearing, but I am not sure how to get the bearings out. Anybody know how? This is a 1985 which is not well covered in the Clymer book I have. Fom what I can see, there are two bearings, a spacer, and the drive pinion left in the case.

Thanks!
