M939A2 Air Dryer Question

[dodgemain]

Hi,
I think I am having a problem with the air dryer on my M929A2. Air is always coming out of the port pictured below. Well maybe not always but a lot of the time. Is this normal? What kind of maintenance should be performed on this unit?
Thanks

Here's the website for parts: Products - Expello
D&D bought Stark. You should plan on replacing the filter element and rebuilding the expello valve.

Thanks for the information guys. That's exactly what I was looking for.

Air Dryer Issue

dodgemain,

In addition to the other posts I'd recommend that you don't run your truck until the problem is resolved. If in fact your pressure releif valve is bad, which sounds to be the case, you'll burn up an air compressor causing a $35/30 min repair to be a $500/5 hour repair (not to mention the possible tow).

Good luck.

Joe
