Rear swing arm - interesting pivot bushes - plastic?
AndyD:
Good timing - just stripping down the swing arm on the CJ360 which has the same bushes and the old plastic bu**ers don't want to come out easily!
Is there a technique to removing them - no worries about damaging them as they'll be replaced but don't want to damage the swingarm itself.
Cheers,
Andy

Hacksaw blade through the hole but you will probably have to cut twice at 180 degrees, wish i could weld steel like those plastic bushes get in the metal arm!
Sesman:
Seconded. I followed Oddjob/Bryanj advice and they basically pushed out. Iv’e used the brass bushes supplied by NJ and the end result is perfect. I got lucky though, the spindle was in perfect condition.

To remove swingarm bushings I take 3 washers that fit in the swingarm. I grind a flat on opposite sides of the washers so they will fit through the bushings. Drop them into the swingarm so they are laying on the inner edge of the bushing below. Then I use a metal rod to hammer out the bushing by pounding on the washers. Once you have the washers made it only takes a few hammer hits to drive out the bushings. It is way easier than cutting with a hacksaw blade.
You need three washers so they don't bend while you're beating on them.
