Swing Arm Removing

[Bald Monkey]

OK, something I have done many times on different bikes over the years, but this ones got me stumped!

I am trying, in vain so far to remove the swing arm, I have undone the nut on the RHS but cant get what I suspect is the lock nut on the LHS to shift, at all. I have tried heat, penetrating oil & a bloomin long extension to the 30mm socket. Any Ideas? Is it normally that tight?

Striping the frame down for a powder coat over the winter.

It's not normally difficult to remove.

The swing arm spindle screws into the frame and is locked by the large nut. How far you screw in the spindle determines the width between the brackets when you tighten the small nut on the other side and so sets the side float for the swing arm.

Since the nut is easily available from NLM, you could drill and split it. Of course you might find at that point that the spindle itself is siezed.

I use a stainless steel spindle and PTFE bushes in the swingarm for a maintenance free setup.

What he said.

Remove both nuts completely so that you can see what you're doing, then use the flats on the righthand end of the swinging arm spindle to *unscrew* the spindle from the frame.

Cheers, its off!!

It was the RHS lock nut 30mm that would not shift.... Impact wrench to the rescue. Just thought I had missed something

I really like the idea of PTFE bushes but am latheless in Devon ( OK if you want a pig resurfacing or a house made from mud-one of the few benefits of my former abode near Swindon was you could get anything done) I did get a stainless spindle and new bushes.Getting the old ones out was hideous.

The PTFE bushes are an on-going experiment, but are looking good so far.

Normally you wouldn't use un-reinforced PTFE for a bush as it will flow quite easily under pressure, but the Morini bush is so large at 50mm wide that it seems OK.

The country is covered in Model Engineers! Ask around on some of the Forums are you're bound to find someone nearby with a lathe.

I made ptfe bushes for a Suzuki years ago but they did not last nor did the bike feel as rigid.

I prefer phosphor bronze but it is expensive and there is lots of waste due to boring it out for the spindle. It lasts much longer.

An advantage of ptfe is that it is very quick and easy to machine and cheap.
