HR Neptune Air Compressor Info needed

I have a 2005 Holiday Rambler Neptune (same as Monaco Cayman) and the engine driven air compressor has gone out. (Actually leaking oil) (Cummins ISB-300 Engine) Service place has not been able to get information on the compressor part number. If anyone has any information on the compressor, I'd be REALLY grateful as I am about to leave on a trip. Thanks!!!!
  • Thanks to everyone who replied. Still working on it. Weekend means wait 2 more days. UGH.
  • If your service place cannot find a part number, you might want to consider finding a new service place. Yours is the kind of problem that occurs every day and there are many service facilities that look up parts every day. This should not be a huge problem.
  • if the compressor was not supplied by Cummins it is most likely a bendix
    and there should be a metal tag on it with a bendix part number that any major truck dealer can use to get a reman compressor
  • Contact Cummins with your engine serial number.

    Or Cummins on-line for your engine serial number.
