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.

I like this method very cunning.

Thanks all,
Cut each bearing in one side carefully and they came out quite easily.
On to the next part that's fighting back - will start new thread for that!

Cheers,
Andy

Just fitted the Brass bushes in the swing arm they went in easily after 48 hours in the freezer.
Pushed in by hand until the last 3/8 " then light tap with rubber mallett whilst collar in place to keep it central.
The centre collar is a bit worn - not listed as available on DS site.

I think you can use a 500/750 one but they are about £80.
Put up a pic of yours and i will compare it to a new 500 one i have(sizes would be good too)

Wouldn't it be the same part number?

No, the original 500/750 was greased by a nipple at each end of the long bolt feeding greas direct to a scroll on the outer surface of the collar, later ones had only 1 nipple screwed into swing arm and you had to fill cross tube of swing arm with grease before it got to a radial groove on the collar.
Dimensionally the colkars were identical but visually very different and for some reason Honda obsoleted the later one

Having had some PM advice I've decided to see how it goes as the wear is very slight - re-asses when in situ.
