Ford Air compressor

[Cameron Reed]

Hi there, just starting to rebuild the compressor off the truck. I think that I'm missing something of the top off the shifter shaft. The top of the shaft look's to have broken at some stage, not sure if there is supposed to be some sort of plate for the spring to attach to, I assume that it is for holding it in or out of gear. Also on the top cover,on the inlet side, should there be something that goes over the oval part then to a filter or line. I have a chev one which has got a filter which looks like out of a rocker cover with gauze in it which screws into the head. Any ideas or photo's would be much appreciated thanks.
