    Default Jackshaft bearing replacement

    I'm managed to pull every bearing I'm going to replace, except for one. I haven't been able to get the break disk off the other side of the shaft to pull it out of the machine. And I can't get a puller on the shaft as there isn't enough room between the shaft and the side of the cowling.

    Is there some trick I'm missing? My next step will be take out the die grinder, it might be alot of grinding, but it beats just staring at the bearing on the shaft.

    Heat and beat. It's been so long since I've done one on an S-chassis Doo that I'll have to look at my son's so I can remember. I'll look tonight.

    Here's what I learned, the collar on the side of the bearing with the setsrew is machined eccentric to the bearing, so that it locks the bearing in place.

    I learned that after cutting the outer race of the bearing with a die grinder and removing the balls and race which made the shaft small enough in dia to get out of the tub. Then it was just a job for the bearing puller. The bearing really didn't look frozen, but definately needs to be replaced
