I have to turn up a new small end bush for my Puch MS50. I appear to have run out of phos bronze. I have some oilite, can anyone think of any reason why this coudnt be used for this job?

I know Oilite is porous so that it retains oil, this might make it slightly less strong, but it must be pretty good, because this is the sort of use it is designed for.

Obviously its designed for shafts rotating in it but in a conrod it also has to take a pounding from the piston, just wondered if this would shorten its life span.

That would be my worry! I know they are strong, but I do not know if they are strong enough! Goggo or threadbare to the courtesy phone please!

Sorry, I am not an engineer so I do not know the answer to that question.

That's strange! Earlier you posted that you would use oilite, now that post has gone, bereft of life it rests in peace, it is an ex-post. Better safe than sorry! Where did you get the metal, Smiths, RS ?

Yeh, I changed my mind to be sure. I got a loverly fit, using an expanding reamer. Clatter at high revs has now gone completely. Got the Phossy from Cookes, Chadwell Heath, a good old ESSEX [not at all dodgy!] engineering supplies.
