thankyou alan ,its very old compressor and its built like a tank, but it has few things on it which i don,t understand ,1 near the external oil filter it has two valves which go into the crankcase, 2 at the bottom of the oil pump bearing housing it has a valve going into the crankcase , and below the suction strainers it has two small rod like pins sticking out

Hi GHAZ
I have a manual but not electronically.
I have had a look and I think the answers to your questions are
1 These are probably for the oil cooler in the crankcase, it is a finned coil and is refrigerant cooled. If it is being used there should be a TX valve on the side of the compressor. 2 The valve could be the oil return pressure gauge and the the pins are the capacity reduction indicating spindle. From what I can gather the pins go in and out depending on whether the cyls are loaded.
Hope this helps
Paul
