Been reassembling the air compressor. Had to make all new studs (except head studs) for it since some heavy handed REME mechanic had stretched all the threads. Got new oil seals but the O/D is smaller than the original so will have to turn up sleeves to take up the difference, and i'm making all new gaskets for it.
Also i've used a part which might be of interest to other restorers, a thing called a speedi sleeve. They are made by SKF and are used where an oil seal has worn a groove in a shaft, the sleeve fits tightly over the shaft, has a cylindrically ground O/D thus providing a new surface for the oil seal to bear upon. They are available in many standard sizes metric and imperial. I have the SKF catalogue on pdf giving all the sizes available, if anyone wants it PM me your email address.
