Repairing an Ingersoll-Rand Compressor
An Ingersoll-Rand compressor, Model RA5T 80V 1M "Rand 4000", 5HP, 230V was left by the last tenant in my shop space. It's likely that this model was sold locally by Northern Tool & Equipment. The compressor leaks a LOT of oil from the air intake. The local shop that services my Rotary and Benwil lifts tells me that the compressor is "not economically repairable" and they won't work on it and describe the compressor as a "piece of junk". I tried to contact the manufacturer, but never received a response. I've never had good luck with the local repair mechanics at Northern (they don't seem very familiar with the equipment they sell, being more of the we-just-assemble-things folks), so I haven't talked to them yet.
Any advice? Is this repairable or junk? Cars I've worked on, but I have never had a wrench on an air compressor.
