Sanden Compressor
Several years ago, I put an aftermarket AC system into my '53 F100. It has a 400 Motor from a '79 F150. Shortly after installing the AC system, I did extensive performance upgrades to the motor, including Serpentine belts. I decided I didn't want to keep the AC, since it has a V belt pulley, and I didn't like the AC hoses running all over the motor.
I never reinstalled the Compressor or Condenser. Now I am tired of kicking them around the garage and I would like to sell them.
I have been told that once the seal is broken on an AC system, and moisture gets in, that acids form and ruin the compressor. My unit has been open to air for a few years now, but the pulley still turns free. This is a Sanden R134 compressor, and it has been in the garage all this time.
What it the likelyhood that the compressor has been damaged?
How can I get it tested?

There's no good way to test it without installing it on a vehicle or disassembling it for visual inspection. You could drain the oil and see if it's discolored from contamination.
If the oil looks good, it's "probably" ok. If it's discolored, pitch the compressor.

Yeah. Used AC compressors aren't really a hot commodity. Some folks will try a used unit to save money, but I usually won't. However, I would consider a used Sanden before I would even think about a used Nippondenso (Ford). Like I said, if the oil is clean and it turns freely with no "rough spots" it's probably ok.

I took the hoses off the compressor, but no oil came out. I can turn the pulley, and I get suction on the suction side, and pressure on the discharge side.
There is a bolt/fitting on the body of the compresser, should I open that up?
This unit has had very few operating hours. Even during the period when it was on the motor, I seldom turned it on.
