Where might I find one of those leveling valve setups? Put one on my other bus and it worked well. Can't seem to find it on the net now. Thanks

You can buy the valves from Automation Direct for 15 bucks each I like the toggle style myself,the gauges you buy any place the guy in Lake Havasu still makes and sells that kit a little over priced IMO

Looks great! The bus I'm buying has a similar setup except for the manual/highway switch. How does that switch work? Does it somehow use the leveling valves?

   Had that system in our 4104. Worked fine for many years. I have all the pieces to put one in the 4905, but have other things to do first. The flip valve is from Parker Hannifan, the push pull valves are like air ride seats, gages from McMaster-Carr or off Ebay. Also uses Bendix double check valves at the leveling valves and controls each front air bag separately when not in Hgwy. I can supply part numbers for the components if someone needs them. Mr. Rideout used to sell the system years ago; has since passed. HB industries sold/sells them but costly.

Am I right in thinking that the hoses all run to the panel?

Now that's really cool setup, and thanks for the tips on some vendors.
Ya had me wondering "drill" after this many years, oh crap!

I have never had the opportunity working with the air solenoid valves with the switch on the end.
Always had real good durability in the road construction stuff though, Its been neat seeing some of these in the different coach pictures, great post here.
Good day

Why do you need "The Driving Valve" as you call them. The bus as a Motor Home typically is loaded the same each outing. There really is no need for the "Automatic Leveling Valves"  I set my manual valves before I take off and have no trouble. The big plus here is my suspension stays aired up months on end unlike when I had the automatic levelers.

My way

Ok, I guess that makes sense. I'm still learning. How's the best way to figure out the right pressure's? Trial and error? And how touchy is it? If your wrong does it put undue stress on the divine? And does that goof up your steering geometry?  Sorry about the questions.  =-O

These are mine "Airbagit" or on e bay 199.00 Aprox two gauges with 2 needles each and 4 paddle valves for up and down simple comes with the t fittings for hoses on the back. I cut out the leveling valves, don't need them anymore either like John said.

So do we really need the leveling valves on our coaches?  If not why would we want to keep them?

No Problem
I'm not sure of the ride height of the PD 4107. Look in your manual if you have one or someone that knows can chime in. Measure to the ground with coach loaded and after you have the height set note the pressure on you leveling gages and you are set. If you are off a bit it won't matter much.
IMO

    In the manual position, the air leveling valves are disconnected from the leveling system and bags are controlled by the push to inflate or pull to deflate individual corners.  You would have six? (don't remember  exactly without my schematic) 1/4 inch nylon lines going to unit. Air supply, air feed from selector valve and one line to each corner. Some do this with solenoids, some eliminate the leveling system. All can work fine. The supposed twisting of the body is not a concern to me with a GM coach. Maybe can happen on a rust laden Eagle or MCI.

Not on my MCI 5Cs mostly aluminum and Stainless Steel, not much steel on it. But they are monocoque frames. I had very little if any rust because it was in Saudi desert and then California. ;D

      My "air bags are steel"!!   I'd like to take a couple of leaves out and add "helper bags" to even out the ride and allow leveling.  I'd love to have a schematic on one of these systems if someone would be so kind to post it!   Would that be convenient for someone?   Thanks,  BH

   You take out leaves and might introduce swaying. If you proceed, consider adding front and rear stabilizer bars.

Bruce,sometimes today I will find the drawing of the Eagle air bag leveling system used on the torsion it should work with springs

    Thanks, Chessie, I'll look at that.  I have a lot of suspension capacity - my bus was built to carry 99 people and the suspension is harder than a red-headed divorce lawyer's heart!   I'm guessing that no matter what I do, I'm going to have a pretty substantial re-spec job as part of it.

    And THANKS from me, too, for the diagram!

Post by: TomC on December 02, 2014, 09:32:22 PM
There's a real good reason only one air suspension leveling valve is used in the front. It makes for a triangular suspension system where the rear axle is the stabilizing end and the front is just for up and down of the front. If you use 4 air valves, you run the possibility of creating a twist on the bus (which I imagine the GM engineers wanted to avoid). Use only one valve for all 4 bags in front-you'll be more pleased with the outcome. Good Luck, TomC

 Ok, maybe I missed something, but didn't someone say you could have the leveling system set up turned off, and the stock or driving setup would be on for driving? If so would the manual valves be before or after the factory valves, or does it matter?

It just how you set it up. a old timer sold a kit a long time ago called level-it.

It has a switch to change from road to park.
