Swinging arm bushes

(1/5) > >>

Mike_Berkshire:
Another newbie question. I am getting close to the point where I can send the frame to the paintshop for stripping/enamelling. I have taken off the swinging arm, removed the pivot bolt & the end caps. I assume that where the manual (Im mainly using Haynes) describes 'bushes' it is referring to the inner (steel?) sleeve. Having only worked on old Brit bikes previously, to me a swinging arm bush is a short brass or phosphor bronze insert. Subject to the bush sleeve being within tolerance I am planning to leave it in the swinging arm whilst it is repainted; masking the ends and the grease nipple. Is this approach OK and is my understanding of what needs to be checked for tolerance correct? Thanks

Nurse Julie:
The old ones you are referring to are like a bakolite. Cut a chanel in them and remove them before powder coating etc. Just cut lengthway with a hacksaw blade and prise out. Then cover the ends for powder coating. I sell the bronze bush replacements.

Thats extremely helpful and I now understand - having properly cleaned the area I can now see. So I remove the inner steel tube, cut out the old bushes, mask, paint, knock the new bushes in, put the steel tube back in, refit arm, re-fit retaining bolt, re-grease? Thanks so much! Mike

I used the bushes that Julie sells in my 400 & 500 - they are spot on.

I put the replacement bushes in the freezer overnight then drited them in with out too much difficulty.

I don't recall any removable inner steel tube, it is shown in the parts book - I obviously left mine as it was.

I never have much luck sawing the old bushes so made a simple tool. A thick washer the diameter of the hole in the swing arm but too big for Bush. File 2 flats on washer to allow it to pass through Bush then drop through to other side and drive Bush out with long drift. Easy! Also recommend bushes sold by Julie.
