I do not know the level of your skill, but a method I use alot is to run a bead of weld(with an arc welder)on the inside of the bushing. Sometimes it may require two or three beads. Be careful not to get any weld were you do not want it. This works great on bearing races and just about any thinner object you wish to shrink out of a housing for replacement.

Be very careful as these are thin. They are loctit-ed in. Just a little heat will break the seal.

Do you do this on the combine or do you remove the hub firstIJ

Well we have always removed the sheave, but now that you mention it, one could unscrew the drive stud, rotate it away from the belt, set to widest setting, heat the bushing while running water on the hub area and use a bushing puller or make one from a nut that had the corners ground to the od of the bushing, insert all thread from the outside and screw into the bushing placed between the sheaves and use a nut on the all thread outside to pull the bushing and puller out through a spacer and washer also mounted on the outside. Gee, if you can follow that you are better than the person I have looking over the shoulder trying to figure out what I just said.

If I could follow it, anyone can. Earlier this week the Chief Money Spender asked if I was getting any use out of the new lathe that is taking up a lot of space in the shop. How long do you think it will take to crank out a new reversible punch and die to change those bushingsIJ
