Hook n ladder 1 Posted December 22, 2013 Share Posted December 22, 2013 My 98 CH613 (427)always had alot of moisture in the air system....well a few years of freeze ups and alcohol, alot of my relay valves have failed. Anyway, air compressor is 5 years old has about 80,000 miles on, will replacing it with a rebuilt one cut down on my moisture issue? How much is a rebuilt compressor going to cost me?Talking about moisture, theres antifreeze coming from the weep hole on the water pump. So I'll be changing that too. So how much $$ is a water pump going to set me back.Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/33981-air-compressor-and-water-pump-question/ Share on other sites More sharing options...
hatcity Posted December 22, 2013 Share Posted December 22, 2013 Have you done any service on the air dryer lately? Have that checked first. The air comp. is a PIA to change.Can't remember the price of a water pump, maybe $400, you will probably need to have the pulley pressed off and on-$25 at the machine shop next to me. Its all the other "stuff" to get the water pump replaced.

Hook n ladder 1 Posted December 23, 2013 Author Share Posted December 23, 2013 I service the air dryer twice a year. It works but cant keep up with the oil/moisture coming out of the compressor. I will not be changing the compressor myself. i have a shop that I will have do it.

Mike Posted December 23, 2013 Share Posted December 23, 2013 I would imagine that the lines and tanks need a cleaning also. Hayden rebuilt mine and I sent it through Fleetpro Company. Took about two weeks to get returned. They paint them black and looks like new again.mike Quote Link to comment https://www.bigmacktrucks.com/topic/33981-air-compressor-and-water-pump-question/#findComment-222676 Share on other sites More sharing options...
gearhead204 Posted December 23, 2013 Share Posted December 23, 2013 an oil pushin compressor is no good, with it pushin oil it ruins the desicant in the air dryer so it cant effectively remove moisture the oil also swells the O-rings in your air valves making for further problems Quote Link to comment https://www.bigmacktrucks.com/topic/33981-air-compressor-and-water-pump-question/#findComment-222677 Share on other sites More sharing options...
Hook n ladder 1 Posted December 28, 2013 Author Share Posted December 28, 2013 So how much will a new or rebuilt air compressor set me back??

1958 F.W.D. Posted December 28, 2013 Share Posted December 28, 2013 Get it all done in one shot. New water pump, new or rebuilt compressor, new belts, and new dessicant in the air dryer. If you have "spitter" valves on your air tanks, I hate those fucking things- they always freeze up on me. I replace every one of the useless POS's with manual drains that I link together with a pull cord that I secure right at the edge of the cab- that way whenever I see it, I reach down and give it a blast and drain out any ambient moisture.
