Title: Both Right Rear Air Bags Leaking
Post by: gracerace on November 10, 2017, 04:42:38 pm
OK, I give. I had been to the HWH tech school when I was a FT tech. I have read all the manuals including the tech manual again. I have read everything on here through search. I understand the leveling system. But maybe I don't. I slept since then! This one has me scratching my head So before I throw parts at my 1997 U295 HWH 600 air system, lets see what you have to say.We are loosing about 1 1/2" a day, only in the right rear air bags equally. In auto, it takes care of itself, but it also wakes me up when it dumps, and is using too much DC when the compressor has to run more then normal. At this point, I have the 2 lines to the Ride Height valve unhooked and capped. I have also been over the system including soaking both bags several times with soapy water. There are no external leaks. Air drop is within range of the coach spec's. What am I missing? I have a few idea's., but don't want to guess. Have a call into HWH, but not guaranteed they are going to call me any time soon. Short handed I was told.This is one of the best reason's for this sight. Help, pretty much 24/7. Cheers, and thanks in advance for your input Chris

I'm not expert on this, but could it be the six pack?

I would also look at the rear six pack, especially RR dump solenoid. At minimum, replace the o-rings on the solenoid valves (posts on forum Wiki with sizes you can buy at a hardware store How to operate the leveling System [ForeForums Foretravel Motorcoach Wiki] (http://wiki.foreforums.com/doku.php?id=technical:hwh:start) scroll down to "Ultimate Guides to the HWH Sixpack ). Even better, if you have the luxury, get a rebuild kit from Tom of the Newell Gurus site which will contain o-rings, plungers, and springs.

Spray the six packs with soapy water from an aerosol bottle (old windex bottle). Soak it down front and back. If you are leaking there you should see something. Be sure to look down in-between the solenoids for bubbles. BTW: air up completely before testing.

Thanks. Have done that a bunch of times, just like you suggest. I pride myself on finding leaks.Don't mean to brag, but when I was a FT tech, They gave me all the air leaks. Customers would come and thank me, telling me they had been to other FT stores, and they couldn't find the leak. If they are leaking, it is internal. I know the coach is due for a 6 pack rebuild, I was just trying to zero in on which valve it may be, by someone else's experience. I have a hunch which one it is. I did get a call back from HWH tonight. They took all my info, and said they will call back. But not today.I will go easy on them,because I love Iowa folk. I was born in Des Moines, and lived in Nevada Iowa till I was 5. Family still lives there. Just glad I am not sitting on the side of the road, waiting for them to return my call! Cheers

Can you take the 6 pack out of the equation, and air up everything downstream of the 6 pack to the rr?

I made a pressure tester that I can attach at different points and pressurize different items and then watch the gauge on the tester to look for leaks. You can pressurize the individual bags and check for leakdown. I have a picture of it but not on this pc. If you would like I could take a picture of it and post it if you think it would be helpful.

Chris: I had a similar problem and finally found a knick in the air line going to the right rear bags. It was a small knick but could feel it when rubbing your hand over the line. Replaced the air line which eliminated the problem. Just another possibility which you have probably checked.

I also put together a thing to help isolate where the leak is coming from. In this case one end to the air bags and the other to the six pack. pump the air up and cut the valve off.(https://www.foreforums.com/imagecache.php?image=http%3A%2F%2FIMG_0371HPG&hash=d600f8687ea1221b7f8dce2c6559a6b1" rel="cached" data-hash="d600f8687ea1221b7f8dce2c6559a6b1" data-warn="External image, click here to view original" data-url="http://IMG_0371HPG) Sorry I could not get the photo to post

UPDATE The front air pressure protection valve for the rear tank is leaking bad. I didn't spray the exhaust hole before, so I missed it. I also didn't hear it, because I was rockin' to the stereo! Have two on order. I installed a piece of straight pipe to by pass till I get it. Don't worry,. not going to drive it. I checked the #'s on my valve,. They are N15759 DG 70 056K MB. Nothing comes up. It is a G, I can see it clearly, but I found a cross reference to N15759 DC 70 056K MB. I also found just #'s N15759 here are 3 that can work with the same specs: Haldex KN31000 Excel PR4 ( PT# EM36850) Mac 20QE2128 Anywhere from $11.95 to $29.00 online + the ride We will see what the RR back bags do overnight Pictures at 11 O'Clock news!

Thanks. I don't buy anything from FT, unless I have to. Wait 2 days to get a returned phone call to order ,then it's double the price. I don't mind paying someone, but there is never any tech support either. I don't mean to bad mouth them, I like them. But friendship is friendship, business is business. Enough said.

UPDATE to the Update: With the air leak fixed, we are at 35 psi loss in 24hrs. FT is happy with 60! With the DOT you are fine at 120 PSI loss in 24 hrs.Works out to 1.5 PSI loss in 1 hr. FT is happy with 7 PSI in 2 hours. There is one small leak next to where I will be installing the new protection valve when I get it.Easier to fix then. real small leak. It stayed level in the rr within 24 hrs. So I hooked up the RR Right Height valve again. If you have been following this, I had both lines capped off at the valve. So now the coach raises 1/4" every 1/2 hour. I made a shut off valve, and installed it inline at each air bag, one at a time. Coach still raised same amount on it's own . I had a new ride height valve, so I threw one at it. Still raises 1/4" every 1/2 hour. My theory is, that one of the solenoids in the rear 6 pack, is leaking back internally, probably the travel solenoid. When I had the air leak before, the coach would drop this same amount. But now with the air leak fixed, it raises. The air loss is slight on the needles. But that makes sense, because the air is filling the RR bags to raise the coach. Hope I get my call from HWH tomorrow. This is crazy.Like I said, have a few idea's, but don't want to start throwing parts at it.If it ain't broke, don't fix it.Just want to fix the one simple issue. Cheers Chris

Chris,
Years ago we had a situation of a front Raise solenoid valve leaking through. We went through 2 shops and phone calls to HWH who diagnosed it as first, a bad level sensor and then second (after that didn't fix the problem), the brain.
Thanks to the forum here, before we routed ourselves to HWH it was correctly diagnosed as an internal solenoid valve leak. We replaced the valve and all was well. Steve took the old one apart and found debris (teflon tape!) on the valve seat.

Thanks. pretty much what I think it is. Strange that both RR solenoids would leak the same.Also strange that taking the ride height valve out of the realm, stopped it. But all things are possible with electronics.. Raised 1 1/2"'s overnight in the RR, exactly what it did in reverse, before I fixed the leak. But that makes sense to me. Air drop was 2 PSI hr overnight . But that is because it's going into the bags. For me, it's not just about fixing it, it's understanding why it's doing it. Thanks again for your valuable input. I post so much here, so others will have a record of the fix. Chris

Apparently if you find every leak in the system you will be ok. Mine has never moved from where set in five years. Dash gauges fall. Not the coach. Check the ride height valves?

UPDATE: Gave up on HWH tech calling me back after 6 days waiting. What a joke. Figured it out myself anyway. Pretty much knew what it was from the start. I hate calling tech line's. Most the time they don't even have people that know much.They are just reading a screen. "Oh, did you check the batteries in the remote?" These places are all over selling their service. Along with most the RV dealers. I mean how can just one dealer in our area, sell 160 units in 10 days, and then take care of those customers, plus the last 160 they sold the month before? Been in the industry for 52 yrs.I wouldn't take a brand new RV if someone gave it to me. Blessed I can work on my own coach. I'll find my own parts @ 1/2 to 1/3rd the price, thank you very much. Cheers Chris

Update to the updated Update! Good thing I ordered 2 new protection valves. The other one started leaking worse then the 1st one. Once I got the leaks stopped, about 4 more popped up on the other tank. 5 hours of testing: Front tank air pressure lost 5 psi in 5 hours. There is one small leak at the large tank fitting on that tank. I will have to drop the tank to fix it. I'll do that later, easy fix. Pulled the R/Rear raise solenoid, took it apart,cleaned it, greased it lightly, flipped the flat 'O' ring over. Pulled both check valve's out, cleaned and lightly greased them. Everything looked fine. Didn't install any new 'O' rings Coach has set 6+ hours. Has not raised or settled at all. Ordered a new HWH RAP1940 solenoid for backup . Have a 6 pack rebuild kit on order with Tom. On the waiting list. Week later, HWH never called. Cheers

Thanks, had already done that.I tried installing a temporary shut of valve at the bags After the air tank leak was fixed, it started to raise 1 1/2", instead of lowering 1 1/2". If I dumped the air in the tanks, it would lower 1 1/2". Bingo. Raise solenoid leaking through! Cheers

I have been to HWH for tech school. I drove up to Miles Iowa to visit where my cousins lived.I was born in Des Moins. My family all lived in Nevada and were farmers. We were building a home when I moved to Idaho 25 years ago. Same thing when it came to hunting season. Thanks for the heads up

UPDATE, TO THE UPDATED UPDATE! So, after 3 weeks HWH tech calls me back. No worries, after 3 weeks I figured it out myself. Probably better anyway.I never called them back.But just a side note. I thought about the harvest thing, and I also mentioned I understand Iowa, corn and farming, as my family were all Iowa farmers. Being born there,I personally worked the fields as a boy. After more thought, I am not pleased waiting 3 weeks for a call back. As I mentioned, I had been to school at HWH twice. This is not some mom and pop store. It is a huge business, with big responsibilities to meet.The previous nice comment about "harvest time, and all hands on deck", should be the other way around. It should be all hands on deck in the service department, if they are going to be short handed.
Thanks for letting me rant. I don't hate them, just disappointed.
So here was the outcome, thanks to all of you and the search feature above. I am posting this, so others will have the info and part numbers.: I rebuilt R/F and R/R raise solenoids using these parts: Skinner Plungers V5-207N. Find Here:
Inventories in Stock by Oemsurplus911.com (http://www.oemsurplus911.com/skinner/skinner_parts.htm)
I bought 6 for like $110.00 delivered
O rings: Fastenal
# 1160809 # 0413870 #110480800
Had to order them, took about 3 days 16 of each $5.00
Grange has them too #IRHC6 1WHD7 #1BYD5
Didn't check stock. They wanted like $18.00 for each size in 50 or 100 quantity only.
I also picked up an extra complete new solenoid here for $110.00 plus the ride. Got it in 2 days.:
Replacement HWH Air Solenoid RAP1940: nwrvsupply.com (http://www.nwrvsupply.com/product/RAP1940.html)
I have seen the magnet (electronic part) fail in the past, so I wanted a spare complete
I fixed a bunch of really small leaks at the 2 front tank's (front/rear tanks) Replaced both safety protection valves listed here previously. The step solenoid was leaking, I had replaced the slide valve, so I used parts from that one to fix the leaking one.
Outcome: Coach does not settle/move/ lower/raise at all in ride height position with key off,indefinitely. Front tank drops 5 psi in 24 hrs Rear tank drops 15 psi in 24hrs This perfectly fine with me
Hope this helps with others that have similar issues in the future.I'am only rebuilding my 6 packs as I go. if it ain't broke, don't fix it.
As my Australian friends say "We got parts, we can fix it"
And I will no longer roll out of bed, onto the floor in the morning! :))

Thanks for the valuable information about air bag replacement. I know there may be some step-by-step procedures out there, but thought I'd ask anyways. My driver's side rear/behind-the-wheel bag is leaking badly. I capped the air line, but the one remaining rear/front-of-wheel bag isn't raising the coach much, so moving may not be an option. I aired up, and need to know what else needs to be done to raise the upper frame member enough to remove/replace the air bag. Should the air be dumped after raising the coach, or can the upper and lower frame members be separated enough to remove and replace, with the HWH leveling activated? Any detailed step-by-step procedures would be appreciated. Thanks.
Title: Re: Both Right Rear Air Bags Leaking
Post by: craneman on April 01, 2018, 10:13:02 pm
You will have to use a hydraulic jack between the arms that the air bags lift. You can't have air in the leveling system to change the bag. It might take a small jack then a larger jack to get the 12" between the frame supports to put in the safety blocks. Then you can change the bags on that axle. Yes there are some step by step posts depending on models.

I realize this is an old post but I found a lot of good information in it as I have a similar problem, left rear is dropping instead of right rear. I was trying to better understand the system. I am assuming that on each six pack valve assembly there is a dump valve, raise valve and a valve for each of the 4 air bags. Is this correct? Also when fully raised I noticed the tag axle air bags look bad at the lower plate. (http://C:\Users\user\Pictures\RV\DSC_0011) Is this normal?
Guess I don't know how to post a picture. I'll keep trying.
