Subject: Air Compressor for air brakes Author: Elmer Aydelotte [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 12/ 1/ 01, 5:42pm The air dryer for the brake air system seems to have a lot of oil mixed with the water when it exhausts. Also the compressor takes about 6 minutes at 1000 RPM to come up to 120 LBS PSI when the rig is started. Is this normal or is it time for compressor repairs. Can they be rebuilt or is it better to get a new or rebuilt one. Any info would be appreciated. Elmer Aydelotte [ Next Thread | Previous Thread | Next Message | Previous Message ]

If you replace the compressor, get a factory rebuilt unit and have a reputable servicer do the work; getting the drive lug off the compressor crank shaft can be quite a task and if you do it yourself you will need a brass hammer. While we are talking about the air system, the factory recommends you release all brake air by pumping the brake pedal when parking the coach. Leaving the brake system "aired up" subjects the seals to unrelenting pressure and will shorten their useful life. Bob Dilks [ Post a Reply to This Message ]

If you are at all handy with the wrench it is not all that hard a job to do yourself assuming you have the swing out radiator. It took me about 4 hrs to do the compressor swap - I bought a factory rebuilt from a local truck parts dist. I now use 2qts less oil per 1000 miles. [ Post a Reply to This Message ]
