Thank you to everyone who responded to my last post. I got a moment to do some testing this AM. It's not building oil pressure. It is full of oil. I runs nice and quiet so perhaps it's still in decent shape? In diagnosing this I noted the oil pressure gauge doesn't move--I don't have a spare so I removed the gauge and turned it on and got no oil in the line to the gauge. Next I removed the air line from the tank to the square box thingie that controls the flow of air to the unloaders. I turned the compressor on and put my finger over the line from the tank (why waste air) and it continued past 20psi up to 50 and was still pumping. I disassembled the square box thingie and everything inside looks great--diaphram etc.
So how to fix it not building oil pressure--ideas? I can't justify pulling down the whole pump but I can for instance flush through it with gas/diesel/carb-cleaner via the tube to the oil pressure gauge. I would then drain and replace the oil.
More advise would be appreciated. Again, it was built in 1968 from the plate on the tank (60 gallon to answer someone's question). It'd be nice if I could clean or adjust something and it start working but if it requires ordering parts it's probably not worth fixing--IMHO.
