tbone1983 Posted June 29, 2013 Share Posted June 29, 2013 I am desperate for help. It started with a failed power steering pump and am finishing up with an air problem. I ended up putting a new compressor on. The truck had a midland on it and all I could get was a bendix. The problem I have is there is a quick release that is leaking air. I replaced it thinking there might be some dirt holding it up but that didn't work. The truck wil not build any air at all.It seems like it is somehow related to the foot valve. When I press it the sound of leaking air changes. The line right off the compressor feeds one side of the quick release. I think the top line of the qr goes to the foot valve and the othere side I haven't traced. I know I didn't do a very good job explaining what is wrong but this truck has me exhausted. I can't beleive the luck I have had. The only thing that changed in the air system was the compressor... So I am at a loss.The truck is a 1987 rd 686s with an e6 and a 6 speed. It is a tri axle dump truck if that makes a difference. I really need a guru here I have to go to work monday. I have already lost 2 days dealing with a brand new defective power steering pump.
