Title: Swingarm Bushing
Post by: linglewn on January 30, 2006, 08:10:17 PM
I am rebuilding a 72 Jackpiner with the rubber swingarm bushing. I am thinking of powder coating and am concerned about the 400-450 degree temperatur effect on the rubber. Does anyone have experience removing the bushings or powder coating without removing it? Thanks for the help.

Last time I did it, I just cooked the bushings out in the powdercoat process and then replaced them. I don't think there's a way to remove them without destroying them.

Thanks for the info. This is my first restoration. Could you tell me where to find the new bushings, please?

I had a machine shop take mine out. Al Buehner on the suppliers page will have the new bushings.

Thanks. They aren't in his catalogue. I guess I need to call him.

Al has a lot of things that are not listed in his catalog. Better make a list of things you are needing before you call him. He probably has most of them in stock.

Swingarm bushing removal and installation can be a bear. Sounds like you're going through the same process I did last year. While I decided not to powder coat, I was struggling with removing the bushings until I read an earlier post. I don't remember who's post it was but all you need is a vise, a small propane torch (you can purchase at Home Depot for $10) and a few sockets. Socket #1 needs to be the size of the bushings itself and able to fit inside the swingarm. Socket #2 needs to be the same circumference as the swingarm. Put socket #1 on one side of the swingarm and socket #2 on the other side and place in vise. Heat the socket #1 side of the swingarm with the torch and slowly close vise. Bushing should come out fairly easily. Repeat the process for the other side. Replacing the bushings is basically the same process in reverse. You will need a vise that opens enough to fit swingarm, both sockets and the length of the busing.

Good Luck,

Chuck
