  • Air Compressor Ran when Parked
  • I bought a Campbell Hausfeld Excalibur 3.5 air compressor That has been sitting in a shed for 15 years. It looks to be in good shape, has a big capacitor motor with belt drive. Vertical cylinder, horizontal tank.
    It looks like it was fairly new when parked in the shed, but has not run in many years.
    My question is: Should I somehow oil the cylinder before I run it? and if so how would you go about oiling it?
    I was also thinking I could turn it over by hand first and see how it feels.
    Input is appreciated...

  • Turning by hand is a good idea either way IF you can somehow oil the cylinder prior to turning would be best. My comp has a pressure port on top that has a small allen head bolt thgat can be removed. I put a manual pressure relief valve in it so when firing it up in the dead of winter, it can first run pressure free. Once it runs a few seconds, close the valve and let it build pressure.
    Does your's have a fastener in the side of the head to remove?
    Add oil, rotate by hand to distribute, fire up comp with plug out and hole covered by rag.

  • Thanks Bruce.
    First I took off the shrouds and cleaned everything well.
    This one had the air intake on top, so I put some light sewing machine oil in there and turned it over by hand.
    Then I plugged it in and ran it for just 5 seconds, then longer then longer.
    It now runs like new and is much quieter then my other ones.
    Thanks for the input.
