Model 14 swinging arm

Postby StuBaker » Fri Feb 04, 2011 6:15 pm

I'm looking for advice about getting the swinging arm on my Model 14 CSR set up properly. Once the bushes are in the frame are there supposed to be any spacers or felt washers? and is it grease or oil that I am supposed to lubricate it all with?
Many thanks
Stuart

Hi Stu,
I beleive there should be Felt Washers
either end,the unit is held together with
a cotter pin. Use Heavy grease or 140
Oil for lubrication.

I'd suggest you soak the new swing arm bushes in oil for a while before you fit them.

There should indeed be two largish felt washers (they help to retain the oil) and I would use SAE140 oil in preference to grease.

The swing arm is a two-piece item, held together with a cotter pin. Make sure you use a nice new one and note that you can take up some play by encouraging the two parts of the swing arm together and then doing up the cotter pin nice and tight. There's a good article about replacing the bushes in the archive.

Many thanks for all that, being a Bantam Boy(?) the cotter pin had me confused. The new bushes I have don't feel any tighter than the old ones which are still in the frame. Is it just brute force to get them out ... or I may jyst leave them as they don't actually look too bad.
Thanks again
Stu

I believe that the cotter pin does not tap completely out (like on a bicycle crank), but only part way?

Considering the interference fit the new bushes will be a tighter fit once pressed in.

Might be a good idea to check the wear on the pin, too; perhaps?

Hi
Thanks again for the advice, the pin looks ok but how would I change it anyway as it's welded to the right arm of the SA? Was this a common AMC trick or just there to catch the unwary?!

Welded pin is standard on a lightweight. If you feel the need to change it Andrews Engineering offer a removal and replacement service.
