The attached photo shows the result of using advanced machine shop techniques for swingarm bushing removal. Axe, club, bearskin and fire!
"Me mechanic. Me have hammer!" :D
I wonder if it's possible to make a puller similar to a fork leg puller.
I'm thinking cut away the inner part of the bush, cut a thread on the inside of the part of the bush that remains.
Then make a threaded 'plug' that screws into that.
The plug would have a hole drilled through it, threaded bar goes through the hole and out the otherside of the shining ingredients arm.
You would need something on the other side that has a recess in it to accept the bush as you wind it through.
I must confess I've never removed one if these bushes, but hearing how much effort is required, it might be worth a few hours experimenting.
A hammer was involved!,, you betcha. I agree that there must be a better way.
I removed the bushings to accommodate my first venture down the powder coating trail. What we do for vanity.
Removing the inner sleeve was a matter of sticking the snout of a torch in the bush opening - the rubber boiled right out of the way. It does make a tremendous mess, but lighter fluid cleans the residue away.
There is a machine shop I use upon occasion. I will go speak with those folks concerning installation of the new bushings.
Onward, through the fog.

We're they worn? You can powder coat with the bushes on place.
:) :) :) :)
I burn the rubber and inner out.
Then weld a lump of metal into the end
Get it all very hot again put a long steel rod through from the other end and belt it out wiv an FBH.
OR.
Get a very sharp chisel and split it all the way along. Pain in etc but it works.
Works for me.

The powder coat requires baking in the oven between 350 ~ 400 F. I was concerned the rubber part of the bushings wouldn't suffer that temperature well. Besides, so I reckoned, the rascals are over 50 years old,,, how hard can it be? Hah!
The FBH technique sounds like a good way to go. Weld in the driving rod, heat the swing arm and hammer away.
I powered coated my swing arm with them still in there without any troubles.
Not looking forward to replacing them, if I ever have to. Sounds a right ball ache, and likely to require a re paint too.
never liked doing them , its bad enough Ive got to do Suzuki Bandit swing arm and shock linkage roller bearings tomorrow. will be dremeling them. had enough troubles today doing my sonsfront wheel bearings on his wheel chair..
as they say, dont see any for ages then two come along at once.
hi there to remove i burn out the centres then use a hacksaw blade to cut a slot in the remaining bush but not quite all the way through then using a long masonry nail i hammer out the bush collapsing it at the split slot . i then use screwed rod nuts and spacers to pull new bushes in regards johnboy .
It's good to learn your powder coating work didn't hurt the bushings; experience had and good to know. John Kay's installation technique has been floating around in my noggin' - I'm glad to hear a proof of concept. Hope to be putting the squeeze on the new bushings before too much longer.
Many thanks for all the input. A strong community indeed.
