Re: York pump Identification and oiling question

[img]images/graemlins/tongue.gif[/img] Here is the scoopola on laying a York on it's side: There is an INTERNAL PASSAGE that connects the intake chamber of the pump to the crankcase. [img]images/graemlins/tongue.gif[/img] That passage allows returning refrigerant to mix with the crankcase oil and do what it is supposed to do. [img]images/graemlins/tongue.gif[/img] WHEN YOU USE THE YORK AS AN AIR COMPRESSOR, you have to plug that little passage IF....and this is the key......the intake is the low port on the compressor when it is on it's side. If the intake port is the high one, or the compressor is used in a vertical mount, NO PROBLEM. [img]images/graemlins/smile.gif[/img]If you don't plug that little internal passage and the intake port is the low port, the lube oil from the crankcase will flow into the intake chamber and for a while you will have very oily compressed air. [img]images/graemlins/blush.gif[/img] After a while the oil will quit coming out and trhe compressor will sieze up from lack of oil. [img]images/graemlins/frown.gif[/img]
