Hi chaps,
I am (slowly) replacing the trunion bushes with uprated polyurethane bushes.
My question is:
Should the bushes be lubricated in any way? And also, the top trunion bushes seem to be quite tight on the pin. Should they be pushed completely into the top trunion, and can this be achieved by just using the lockwasher and nut?
Any advice gratefully accepted.
Regards
John

The top trunnions squeak like mad if you don't grease them

Re: Polyurethane trunion bushes
This one is an interesting debate. Grease or not to grease?
I fiited Superflex bushes everywhere as part of the restoration 13 years ago and did exactly as instructed at the time, which was to use some washing-up liquid to assist the assembly process - worked a treat and I have had squeaks at low speeds ever since! Greasing should not be required as the principle is that the bush is held tight on the outside and the inside, and neither should move; the movement is within the bush itself. So if grease is used the bush could turn, which it is not supposed to do.
The theory is OK, but if I fitted them again I think I would use grease to avoid the squeaks! Mind you, there is no sign that any need replacing any time soon, so they do work!
