I believe the replacement is 1720-11

I noticed that the Mac valve has a muffler

Andre, I think your assumption was correct although I don’t know much about the H3.
The units buried in the belly of the bus just like the ones behind the bumper draw air through the coils horizontally, but it comes up through the wire mesh opening in the belly. The ones behind the bumper draw through openings behind the bumper or through the shutters. All discharge out the bottom
That applies only to Liberty. Others may do the same but I do not know that.

Just fooling Harry. My toggle switch has a picture of a man lying in the road with tire tracks up his butt!

Maybe Harry isn’t pushing the right button.

Do you know if they went under the valve covers for fix?

If it’s Texas hot I always wet down the pad before we park then the coach shades it and keeps it pretty cool… We have never had to raise the coach but that’s a good idea and never had the HP warnings except in the Vantare once running down the road… we have never run them on the highway in the Liberty…. OTR does the job nicely.

Cheers Diane

That valve is designed to be either “ON” meaning air is directed to the bellows (cylinders) that tighten the belts, or “OFF” meaning all air is exhausted and the belts relax so they can be removed or replaced.
This doesn’t need to be a complicated discussion. If air is heard find out where it is coming from. It is either the valve or pressure regulator or one of the fittings. Spray some soapy water and look for bubbles. Whatever leaks, fix or replace.

Harry mine doesn’t dump air when I stop engine. Don’t think it should. Want to keep all air you can in system to keep belts from flopping on start up.. I figure the original valve on mine and any of them will have some kind of dump to release pressure on cylinders to change belts. Might just have a faulty valve.

Harry is that valve down or overhead? Mine is up right between center of doors. Have to reach up to reach it. It’s hidden unless you know where it’s at on mine. Had a level 3 done in Houston a few years back and pulling car back bus started heating at cruise speed. Slow down and it would cool down. Belts were turning and looked okay. Limped it home and the Guy that helped with it found out somebody had released pressure and belts were slipping.

John is very good but none of us are perfect. I am sure he will work hard to take care of you. It will be fine soon, just unfortunately not today.
None of us wish anyone this delay. Hang in there please Sir.

I took The Beav out on a good run today and once back and shut down I went back to the engine compartment to see if the air leak was still there and it was. But this time I found it and not even close to where I thought it was.
Here’s a couple pictures. The handle is in the position when it’s releasing air. If I turn it down about half way the air stops. If I turn it all the way down the air comes out faster.
I left it like I found it and is as you’re looking at it. What is it and what do I need to do?

Dan and Judy,
Congrats on new bus. It should lessen the pain somewhat from losing the other coach. Hope we get to see you this winter in Florida so you can show it off.
