Does anyone know the part number for the front hwh 6 pack on a 98 u270?

I just bought 2 complete valves here:
Replacement HWH Air Solenoid RAP1940: nwrvsupply.com (http://www.nwrvsupply.com/product/RAP1940.html)
Super nice people. Sent them Priority mail to where I am at. I highly recommend carrying one complete with you.I carry the rebuild kits with me, but lost the magnet portion of the valve in the middle of the desert. Luckily I had a new spare with me. You won't find these in the auto parts store.
6 pack's easy to rebuild. I chose to fix them as they start leaking. Guess I am lazy.

As has been indicated you likely just need solenoid refresh. If, however, you need a new aluminum block, you can buy one from the manufacturer. They have to make it and the cost is over $800 for the blank block.

Can't you buy the replacement block from hwh for about 850$? With the solenoids ?
Would that were true! I would have bought it. I talked with Mary at HWH in October (2017) and she quoted me $802 for part number RAP9283 which she described as the drilled aluminum block. She advised me that all of the parts (solenoids & pressure switches) had to be purchased separately. I'm still looking for a used block but not having any luck.

What is wrong with the block? Just curious....Machine shop can't repair?
The aluminum block is just flaking apart. The corrosion goes right into the drilled-tapped holes. I did a half ass rebuild on it by cleaning, painting and replacing o-rings and it is not leaking but I can't abide something like this. I hope to find a replacement that is in normal condition. I've had three FTs with six packs and never saw anything like this and I'd like to take care of it.

Same here with the flaking six pack. Hope you find and share your solution.

What does the rear HWH manifold look like?

Possibly a electrical problem? I know some vessels use sacrificial aluminium anodes instead of zinc ones.
The rear manifold looks OK. I just cleaned it off with the intention of rebuilding it later. Hate to think of my front as sacrificial! :) Interesting that you also have this issue, Roland. Anyhow, I'll keep looking for a replacement.

I am surprised you were able to get it all sealed up. Hope you find a used one reasonably priced.
I think the rear 6-pack manifold is often "protected" by the thick layer of grease and dirt that naturally accumulates on everything in that vicinity. Probably one of the good reasons to resist taking a steamer to any of the critical components under the coach.
I agree the corrosion on Jor's manifold looks terrible, and I wouldn't like it either. However, as long as it is surface damage, and does not affect the function of the unit, then replacement is not mandatory. None of his photos show the sealing surfaces under the brass valve bodies. Those are the critical areas of the block, where any imperfection or roughness might cause a leak. On the other side of the block (shown in the photos) where the hose connectors screw in, the condition of the surface is only a cosmetic concern. As long as the threaded holes are intact, they should seal and work fine.
If anyone comes up with a source for a reasonably priced replacement for these manifolds, please let the Forum know!
Wonder if this might include the six pack?

I was confused .. I was thinking the bladder manifolds. I have seen these on ebay from time to time
Therein lies my frustration. They tell me they don't have one but I suspect they do. Just never heard of anyone wanting one of these things used. I'll give them another call just in case. I also called Visone as they have wrecked FT and they also said they didn't have one but I suspect they can't find it.
Another thing according to HWH. We really have to buy the manifold that was made specifically for Foretravel. Others, for example Country Coach, look the same but are drilled differently.

Finally got around to installing my shiny new front HWH manifold. Thanks to JerryW I got the pressure switches in the right holes. The new one is set up a little different than the originals. The exhaust ports are threaded for some reason. Anyhow, works like a charm. The back one is in a lot better shape so I'll just rebuild the solenoids.
The front original looked awful. I couldn't even separate the cans on four of the solenoids as the nuts were welded onto the stud I cleaned it up best I could, threw in some new o-rings and bolted it back up. It worked fine for the last year but now I have a bit of peace of mind.
One other thing, was it JohnS that posted a few years back the idea of using different colored zip ties to ID the electrical connections. Worked great.

When I was in the loader business, did lot's of demolition jobs. Loved the phone trunk lines I took out. saves my Snap-On number tapes.
Jor, Where did you end up finding the HWH manifold?
Could it be possible to mill the block to remove corrosion?
I ordered it from Foretravel and HWH shipped it directly to me. Same as JerryW. It was $634.50 with the Motorcade discount.
