I just freshened up my allis chalmers c with new main bearings, rod bearings, cam bearings, rings, valves and guides. It was running like a swiss watch. When I went to start it up last night to move it, it misfired and ran backwards momentarily. When I got it going I noticed right away there was no oil pressure so I shut it down. Is it possible that when it ran backwards the oil pump lost prime? or could the little drive pin have sheared? Its just strange that it went from having good oil pressure to none. I know I got some timing issues to clear up but I would like some advice on the oil pressure problem first, any help would be greatly appreciated! Thank you!
