Accessory air compressor leaking air....help with a part #

[stacyhall]

 

2006 Camelot 42 DSQ losing air on driver side only in the system within 3 hours when parked and in level mode. In travel mode no issues. (Travel mode had the issue last July which was a air leak at a connector so we had all of those connectors replaced with brass fittings )

 

HWH leveling system with a power gear accessory air compressor(that has not worked in the 2 years we have owned it, never leaked prior to two weeks ago). Accessory compressor has its fuse pulled, if you put it in the pump just runs until it blows the fuse.

 

The hunt for the air line leak begins. So Ted Zimmer wanted me to post this and see if anyone has any advise or has had this before.

 

Safety 1st built 2x12 step up ramps yesterday.

 

First air leak found in 2 minutes. See the photos it is at the accessory compressor at the side.   Been looking online for a parts list for the power gear 501184 compressor to see if there is a gasket where the leaks is. No luck anyone have a link to the parts list or know if there is a gasket.

 

Second leak found a few mins later. At the front air tank anyone replaced this fitting. Tried to put a wrench on it but nothing fit where it leaks is at the swivel of the fitting. So replace it ? Anyone have a part # for the fitting.

 

It was getting dark so he stopped looking after these 2 leaks. Will finish testing all the fittings tomorrow hopefully just these 2 leaks

Any and all advise appreciated.

There’s another aux air post with 4 pages below your post. Near the end of page 4 I posted info about my pump and what I was replacing it with. Adapting to the air output was the hardest part. If doing again I would put a barbed fitting in a short section of the yellow line.

I would say that you have Power Gear leveling, not HWH. The solenoid connectors give it up but it doesn't really matter. Yes, you found leaks but these will not stop your leveling problems. Spray the sixpacks, lines to airbags and finally the airbags on effected side.  The coach should stay level with no air in tanks.

[stacyhall]

not to sound dumb but can you explain the theory behind why having air leaks is not the root of our issue.   last year we had an issue with 1 connector that when in travel mode the air would go out in less then an 5 mins making it not drivable, tech found the bad plastic connector, replaced it with a brass connector (this bad one was at the rear of the coach) and back in business no issues.  As preventive when in having service in October we had them change out the other plastic connectors.  Now 5 months later travel mode still works great, it can sitting in our drive way in travel mode  and not lost any air in the bags.  We go to a rally last week, arrive, go to level mode (we are air level only no jacks) come back 3 hours later leaning to the driver side.  Turn on the coach and air up stay in travel mode for , no leaning.  Think that maybe because it was cold the first few days maybe that cold caused an air leak at a fitting or o ring, go to level mode and within a few hours leaning to the driver side.  So far Ted has sprayed down the driver side front airbag, no leak there, today he will continue his spray and search mission.

We have had our Camelot for going on 2 years and this is the first diesel we have owned (previous 2 were gassers) and very first experience with airbags and air leveling.  Just trying to better understand the coach and how this system works.  We have looked over the file I am attaching to this message as someone else recommended it to us but we are still trying to wrap our heads around this leaking, tanks and fittings.

At the Monacoer rally in Tampa this year they discussed that all systems will loose some air, Dave said his Foretravel looses some over time but we know something is going on and there was a reason the previous owners had the fuse pulled for the accessory compressor (that was leak #1 Ted found).  So we are going to replace it.  I know Scotty said we could rebuild it but we had had no luck finding any part diagrams for the original Power Gear accessory compressor.

We appreciate all the knowledge in this group and are sponges ready to absorb the recommendations of the group. 

Ted did take video showing the compressor and leak but cant get it to upload to the site, if it is helpful we can put them on our private youtube channel and post the link here if anyone thinks that will help in the trouble shooting of the issue

The simple reason I said that is that the minor leaks you have found so far, are not side specific. The division/isolation between sides while leveled, happens at those mentioned six-packs, one each for front, rear and tag. These six pack valves are supposed to be closed and keep the bags at proper pressure regardless of what happens with the main tanks. Six-pack valves do develop leaks, nothing unusual and usually just need new seals. The airbags, lines and fittings between them could also be a culprit.

Is the arrow in your first pic pointing at the hole where the air filter is supposed to be?

[stacyhall]

That is air leak #2 found. 

[96 EVO]

Sounds a lot like the issue I recently fixed.

Read this long thread, and see the pictures Frank McElroy posted in page 2.

If the reed valve in the compressor head isn't sealing closed, you will lose a whole lot of chassis tank(s) air, regardless of whether the compressor is functional, or not.

Unfortunatly, even if you make this repair, you will still have the issue of one side / corner dropping.

It looks like a PPV ( pressure protection valve ) to me.  It's a little hard to see the part of it that is turned up.   They are known leakers.

There is nothing special about our PPVs.  Just take one into NAPA or about any other place and match it up.                                                                                    You probably have 2,  so you may want to replace both while you're at it.    If it leaks at the tubing you can often cure that by just cutting a tiny bit off & reinsert.          Cut it as square as possible.

Yeah, I was asking about the arrow in the aux compressor pic.

[stacyhall]

The arrow in the aux compressor is where a leak is. Which does not make sense because that is just a bracket to hold it in place it looks like. Guess we will see when we pull it apart to install the new one 

[96 EVO]

Ah!

I thought maybe your arrow was pointing to the air intake hole.

[Guest Ray Davis]

Sorry Ben,  you said in the 1st picture but I missed it.  🙈     I knew that you knew what it was but wasn't sure others did.

Yeah, probably the way to go since the compressor is DOA!

Kill two birds........

so we purchased the Firestone 9335 12 volt aux air compressor.  Ted got it all installed and great news....it shut off like it should and no air leaks in the side of it like the original one did....so that was step 1.  Bad news after a few hours it has to kick on and seems like it is running for too long 15 to 20 mins to shut off again.  Back under the coach Ted goes with the spray bottle with soapy water ted goes....found bubbles in 2 places so the next few days he will replace those fitting and see if it stays off for longer then the 2 hours.

Question for those that their aux compressor is working. 

How often does yours kick on when out camping? 

How long does it run when it does kick on?

crazy thing is that we have been in level mode for 2 weeks before we replaced the aux compressor and it has not leaned at all (like it had in our previous post).  I had done some research on the compressor and found a beaver site where they say that if it gets cold out their beaver looses air and will lean...it has warmed up in Georgia to the point it has not been below 40 and when we had the lean it had been down in the 30's.  Just wondering if anyone else has a lean when it is cold?

Thanks to everyone for suggestions and comments, we are coming up on 2 years of owning our 2006 Camelot 42 DSQ and love it.  Getting the aux compressor working has been on the list of things to do so happy we are close (hopefully) to achieving that.

Got new blinds while at the FMCA rally super excited about that.

Just purchases a LG washer/dryer combo to put in the full bathroom (it was factory set up for it but original owner did not opt for the install), we will loose a cabinet but going to be worth it.  Cant wait to muscle that beast (160lbs) in the front door and back 43 feet then lift it up 1.5 feet and get it in the space.....i will leave that for another post, and not talk about the fact is is 23.4 inches wide and by removing the trim on our full bath door we will have 24.4 inches to navigate through.

Thank you again!

When I arrive at a site, auto-level, then shut down the leveling system, I can go over a week before the aux compressor needs to top up the leveling tank. Reason for this long time is the leveling tank also gets air from the chassis tanks till their pressure gets >90psi. 

After that happens, my compressor may run once a day.

When it does run, it's about 30-45seconds.

Many folks shut off the “auto level” or just shut down the panel.  You may (probably” have the Valid Powergear system.  I and several other experienced users shut it off.  If your MH is staying level and no Aux Compressor comes on, then, your air leveling side is working.  Folks often replace the compressor and then are “bothered” as the system will try to correct or come on…typically in the middle of the night.  

I replaced my Aux Compressor switch (it never worked NEW….I bought the MH NEW), until I troubleshot it and found a defective switch. So, I left the auto leveling system on and then ithe compressor kicking in became a nuance.  I lose my “air brake” air in 7 or so days.  Monaco had a standard that a warranty air leak had to go to zero in 2 days or so…. 

Bottom line….we never lose level. MH can sit in storage for months and never drop a corner even a fraction of an inch.

AUTO LEVEL is fine.  But many of us drop all the air, then manually level so the level position is closer the ground level than perched up like an ostrich.  That keeps the step closer and easier to get inside without an auxiliary s5ool.

The is no one absolute must be done this way answer….this works for me and several long time experienced MH owners….

[Ivan K]

Same as Ben and Tom. My auto-level works fine so I do that and shut it off. Often, on very unlevel ground, when some bags end up near fully extended while others near empty, I need to relevel in the morning again because the night temperatures play havoc with uneven volumes of air. After that first correction we are usually good.

Next time your new aux compressor starts up, turn your ignition key to run position, and watch your chassis air tanks.

I'm beginning to wonder if you have a

couple of bad check valves, and that little compressor is charging your entire air system. 

15-20min of that new compressor running, your leveling tank should long have blown open the 150psi relief valve, which would make a lot of noise!

Correction * I think it would only have to be a faulty PPV at the secondary tank. I don't think that line has a check valve at the leveling tank.
