Got my compressor back together and made a tank full of air. The thing purrs. I'm going to order O rings for the unloaders and a new unloader control valve. I can't get this one to work right. Thanks a lot Roger for the info. You saved me a lot of hunting around. I owe you one. Let me know if I can help you. I'm an electrician by trade, and now heavy into computers, hardware & software. Thanks again RF.

You're welcome Richard. If you want to save a few bucks and do without the low oil pressure protection, you can just install a regular in-tank check valve with a 1/8" NPT blowdown port and plumb it into a new pressure switch with a needle valve unloader. It would probably be a cheaper way to go, since you could just get some large fine-thread bolts and nuts and cinch the intake valves down like the outlet valves are now. Not as elegant as the original design, but probably a much cheaper setup. BTW, I guess you know how to set rotation, since you are an electrician. Just make sure there is oil pressure. With the type of oil pump on yours, there is a small collar that the vane pump runs inside. It is supposed to self-adjust to whichever way the compressor is rotating, opening and shutting the correct oil ports inside the oil pump by rotating about a quarter of a turn with the vanes. Sometimes this collar will not self adjust, and you have to take off the backmost cover and rotate the collar by hand. A punch and some light hammer blows will suffice.

I have also gone the computer route a few years ago. I got a computer networking technician diploma, and a Microsoft Certified Systems Engineer certificate. Unfortunately, so did a milion-billion other people, so I am returning to school (if the funding arrives!) in August to do a Photonics Engineering Technologist program. 3 more years of poverty, hopefully with a little better result this time!

Regards.

Roger.

I think I'll just get the new controller valve and minor stuff I need. I've spent $100 on the compressor and about $225 on parts so far. Maybe another $100 is ok. The cylinders still had hone marks in them and no ridges. Like you said this thing will last me my lifetime now. I got the compressor spinning correctly and have oil pressure on the gauge. Comes up to about 25 lbs. Looks about right near the top of the scale. Thanks again.
