$120 isn't a bad price for an entire assembly. But it can be rebuilt for much less. I can get the seals for $10 and make the gaskets.

I got a complete valve from Memphis. When I called them I talked to the shop foreman. Seemed to be a very helpful guy. I told him what it was doing and he suggested that it was probably the air shift cylinder on the transfer case. He said that most likely the seal on it has a cut in it and is letting air return to the valve which is venting out of the valve. I guess I will see. Memphis does have parts for the valve. They are not complete sets but they do have the disks with the rubber on it and the other parts, but no springs. We went with a complete valve because we need this truck back in service ASAP. Hope to tear into it tommorrow morning. Hopefully it is something simple. Thanks for all the replies and help.

I went and worked on the two five tons today. The one with the sprag issue turned out to be the air cylinder needed rebuilt. I took it apart and the rubber seals were hard and the piston fell out on the floor. I installed the new seal cups and the snap rings. I ended up with two O rings left over. The one that was in it did not have any O rings that resembled the ones in the kit. I ended up using the old copper washers as the new ones were just a little smaller diameter and would not hold air.

After I got the first one fixed I drove to the other station and looked at the other 5ton with the brake issue. I started it up and pumped the pedal a few times and was able to lock the brakes up just sitting in the station. I could hear the airpak venting each time I pushed on the pedal. I think the master cylinder is the issue by the way that the pedal acted. It acts like it is not releasing back. We will take it into the mechanic on Monday and have them tear into it. For liability reasons I would just as soon have them work on it. Thanks for the replies on the issues I had.

You should add this to your other threads that you started when these problems first were posted so the fix will go with those threads

Total cost was under $50.00. I get to send the air valve back. Thanks for all the help.

I rebuilt mine today too. Gonna have to raise **** with Memphis Equipment. Those copper washers are definitely too small. I cleaned mine up, flipped them over, and put it back together. Worked fine after that.

I merged the two threads, from now on, please just continue the same thread and update as needed.

Did you have the O rings too? I couldn't find any place to use them. Did you?

Sorry about the posting error. The other forum I am used to posting on the threads disappear down the page so you have to post updates under a new thread.

My kit only came with spring clips, 2 rubber seals and the wrong copper washers.

My kit had the 2 seals for the piston, a seal for the shaft going into the transfer case, 2 snap rings for the springs, 2 O rings that I could not figure out where they sent, and the two copper washers that were the wrong size.
