Dr4Film Posted February 2 Share Posted February 2 Do any of the members here know the part # for the HWH 6-Pack Air Manifold for the rear and front 6-Packs? Is there a separate air manifold for the Tag Axle? I have the HWH-2000 Air Leveling System with a Tag Axle. Thanks so much for your help! Link to comment Share on other sites More sharing options...
Ivan K Posted February 2 Share Posted February 2 I don't know the part numbers but yes, there is a third manifold for the tag. The manifolds should have different number of pressure sensors so I suspect a couple of different part numbers but not sure about that. Mine are still in good shape so did not need to find out.

Dr4Film Posted February 2 Author Share Posted February 2 My reason for the part number is to get a used 6-Pack, rebuild it on my bench, then swap it out with the rear one. Then rebuild that one to swap it out with the one in the front. The tag one I can rebuild it without removing it. 1 Link to comment Share on other sites More sharing options...
vito.a Posted February 2 Share Posted February 2 This may be a question for AZ Pete. I'm afraid a new 6-pack price would be in the thousands! The internal o-ring is a -019 size, the large one on the bottom is a -028 and the small one on the bottom is a -015. Mike Canter suggests you upgrade to Dupont Viton o-rings. 1 Link to comment Share on other sites More sharing options...
Dr4Film Posted February 2 Author Share Posted February 2 I have all of the correct size o-rings plus a couple of solenoid valves for backup. Don't need a new one. I have Visone looking for a used one. Just need the part number in case they ask me for it. Link to comment Share on other sites More sharing options...
Ivan K Posted February 2 Share Posted February 2 I did not mess with the hoses and wiring, just left the coils hanging and removed just the valves to rebuild on a bench. You may run into a leaking plunger seal too after you put them back together. Link to comment Share on other sites More sharing options...
Dr4Film Posted February 2 Author Share Posted February 2 That's exactly why I want the entire 6-Pack block removed to rebuild it on the bench. I can easily do a pressure test while it is sitting on the bench versus in the coach. Link to comment Share on other sites More sharing options...
Chargerman Posted February 2 Share Posted February 2 I pulled mine out when rebuilding. Those rear ones are a bear to get to to remove. Not a job for folks that are not somewhat fit. When reinstalling I trimmed each air line 1/4” or so they have a fresh hose to seal with the fitting. One other thing, I have to resurface the face on my manifold by lightly milling them as there was a good amount of corrosion and I was afraid that some prongs may not get a proper seal. Richard, If you’re going to rebuild the spare one on the bench then swap, why not just remove yours, rebuild and reinstall? Best of luck with it. Not a fun job.

Dr4Film Posted February 2 Author Share Posted February 2 It makes getting under the coach into a tight place only one time instead of two. Don't like working in that area more than I have to. 1 Link to comment Share on other sites More sharing options...
Chargerman Posted February 3 Share Posted February 3 I certainly understand that thought. Very tough area to work. Link to comment Share on other sites More sharing options...
MHRookie Posted February 3 Share Posted February 3 Richard, Didn’t know if you saw this or not. Not real definitive but it’s all I could find for manifold part numbers. Just scroll towards bottom of page to see breakouts. I only found one “manifold” page and all the coils or valve kits are the same numbers… (Forgot if I can post links to web pages… so I left off)…I googled HWH parts list and found a live page with links. then selected “air control units”. I never did see a breakdown of specific model units. Link to comment Share on other sites More sharing options...

NAMVET77 Posted February 4 Share Posted February 4 Richard I’m about read to rebuild the air valves on each 6 pac on my 04 Camelot. I wasn’t planning on removing the manifold. Guess it depends on how good or bad it looks. My question is where did you get the spare coils? I checked with HWH and they want over $100 bucks for each one. The guy I talked to didn’t know what the resistance each coil should be. I’ve heard 10 or 15 ohms. The spare I have measures 11 ohms. I guess I could do a voltage check to see if the coil activates the air valve. Link to comment Share on other sites More sharing options...
Chargerman Posted February 4 Share Posted February 4 On my coach. Rebuilding the manifolds (oring replacement) would have been very tough in place. I also wanted to trim the air lines so they got a fresh bite on the fittings since I found a couple that were slightly leaking. If you have resistance across the coil it should be good. They are usually the reason for valve failure. Link to comment Share on other sites More sharing options...

It included two new complete solenoid valves plus multiple packages of the required o-rings for rebuilding. I scarfed it up quickly knowing the project I had ahead of me. Some time back I saw a posting where a member listed a new coil that would work on the HWH valves. I have kept that information just in case I needed it. Here are the Amazon links to that coil. http://tinyurl.com/2bzcfe59 http://tinyurl.com/ypjt8z6d I have not ordered any of these so I cannot confirm that they do work as a replacement. Obviously, you would need to replace the connector with the one from HWH to make it work. Edited February 4 by Dr4Film Link to comment Share on other sites More sharing options...

timaz996 Posted February 4 Share Posted February 4 I guess I was lucky because I didn’t have to replace any of the solenoid only clean them and replace the O-rings. Link to comment Share on other sites More sharing options...
NAMVET77 Posted February 5 Share Posted February 5 Thanks Ivan and Richard for your feedback. Don Link to comment Share on other sites More sharing options...
Ivan K Posted February 5 Share Posted February 5 In recent past I snatched few old stock rebuild kits that fit the HWH valve plunger, not exactly the same but they fit and work. Not enough of them to rebuild all 18 of mine but they each came with a little nut looking adapter, to remove the stem of the HWH valve easily. I like that it simply needs a wrench or deep socket to replace the plunger even on the road without disturbing the 2 main orings, even in the tight squeeze under the bus. I have few of those adapters to share if it helps someone. Link to comment Share on other sites More sharing options...
NAMVET77 Posted February 5 Share Posted February 5 Ivan, I'm about to rebuild all the air valves on both 6 pacs. I would like to have one of the nut adapters. My email is hikenbike77@gmail.com. I will gladly pay for the shipping. Thanks. Don Link to comment Share on other sites More sharing options...
