Purge valve on air system

Yahoo Message Number: 93397
Air compressor is cycling to often and it's not holding air pressure very long after shouting down the engine. ( 30 Min.). I can Hear air leaking at the purge valve on the air drier.
Is this something I can fix or do I need to take it to a shop.
I it's a Cummings engine 325 hp.

If I need to take it in where is a good place to take it in the Dallas, Tx area.

That's a repair that requires the right equipment (pit or lift) since as you've already noticed the coach will squat when the air drains. I've a '98 Intrigue and had the Haledex air dryer serviced (CC recommends replacement due to extra use by HWH leveling).

CC labor estimate was 1.5 hrs, I was able to get TransWest Truck/Trailer (Longmont Colorado) to do the repair for me. The dryer was located in front of the transmission/drive unit... on a little shelf that is approximately under the foot of the master bed.

Good luck

Man I have gone round and round with my dryer. It could be your govenor easy to change located on your compressor. Or the purge valve, dryer, leak in the signal line from govenor to purge, or leak somewhere in a line. Droping pressure in tank, our air gauge only shows two of the three air compartments.
Our purge stayed open on the road, lost all pressure. Ended up bypassing the dryer on the side of the interstate and finished our trip.
I replaced the dryer completely $225 and the govenor $25 found a few small leaks and repaired. In short take it anyplace with big rig experience that will work on a RV. I spent two days under that thing was a real pain.

I replaced the purge valve on our 98 Intrigue, wasn't that difficult. Built some tire ramps out of some 4x6's and 2x6's. Ran ALL the tires up on the ramps and made sure that I could fit under the coach with ALL the air out. I'm kinda skinny! Got the parts from NAPA pulled the dryer and put in a new purge valve and a cartridge. Ended up replacing the ride height at the same time.

Note if you ever lose the purge valve and lose all your air you can bypass the dryer using a 1/2" pipe elbow. That happened to me and I drove about a 1000 miles before I repaired the problem.

Joe,

Last time I had mine replaced it was done at Lazy Days in Florida and they use the same type boards to drive the motorhome on to get the clearance but they charge a little more per hour than you got charged! ;-) How difficult was it to get the old valve out, lots of torque or easy?
