That's an o-ring mating surface, it should be as smooth and clean as possible, and you need to be careful not to scratch it. Any radial scratches that cross the mating area can cause leaks. Yes, and easy to bugger an O ring screwing the solenoid on, or any of the O rings for that matter......Ask me how I know.... Chris Quote Selected 1 Likes

Chris Just a tiny dab of o-ring grease (not too much, just enough) between clean thumb and forefinger, then gently drag/rotate (don't tug/stretch) the o-ring between them to LIGHTLY lubricate...(I spent too many years maintaining thin film vacuum deposition and etch equipment. Lots and lots of flanges and o-rings...) Quote Selected 6 Likes
Re: Working On My Six Pack Reply #77 – September 08, 2021, 03:21:08 pm I am still trying to figure out how the people that do this job without removing the manifold from the coach keep the o-rings clean. I came out looking like this. Quote Selected 7 Likes
Re: Working On My Six Pack Reply #78 – September 08, 2021, 03:37:52 pm Job is easier on some coaches than others due to location of the manifolds.On my U280 the front manifold is a piece of cake. I can roll under the coach on my creeper and then sit up to work comfortably in the shade, with the manifold hanging there at face level, totally unobstructed.My rear manifold, on the other hand, is just the exact opposite. I am a LOT dirtier than you after working on it.Plus, some extremely fortunate Forum members have service pits where they park their coach. Working underneath a coach while standing upright is much nicer. Quote Selected 3 Likes

I came out looking like this. ElliotDepends how dirty the coach is underneath. Mine is pretty clean because I pressure washed it when I got it, it also has no road rust/crud.I wonder how others do them off the coach, without getting crap in the air lines, and not making a mistake mixing them up. I get the colored zip ties, I get the tin foil over the lines, but still too much room for err for me. I like doing one at a time on the coach.Whichever way works for someone, is the best way. Did front and back in 1 hr on the coach couple of yrs ago. Still going strong.Chris Quote Selected 5 Likes

I came out looking like this. Take each solenoid off the manifold as a complete assembly and rebuild it on a table then re-attach it to the manifold as a complete assembly. No need to undo any airlines. Just a ground wire and the plug wire. There is no need to partially disassemble the solenoid while it's attached to the manifold. Quote Selected 5 Likes
Re: Working On My Six Pack Reply #83 – September 16, 2021, 10:41:09 am I rebuilt my front six pack last night and there's a special place in hell for whoever decided to put it in that location. I couldn't get to the top four air lines so I took the Twig approach and removed three solenoids at a time while the manifold was still attached.It was quite the contortionist act loosening the two mounting bolts at the top to allow enough room to spin the top solenoids off. Reinstalling the HWH tank by myself was also quite the feat thanks to some very stiff airline fittings.If I were going to do it again I'd probably see if I could rent someone's pit or pay for an hour on a lift somewhere. Some ramps + safety blocks might work too. Quote Selected 3 Likes
Re: Working On My Six Pack Reply #84 – September 16, 2021, 11:19:53 am Don't remember where I read this but I think someone had moved the 6-pack to a more accessible location. Basically you'd just need to extend the wires and tubing. Quote Selected

Re: Working On My Six Pack Reply #86 – September 29, 2021, 02:33:59 pm I rebuilt the front six pack about six months ago. Was not difficult just make sure where everything goes. Label them if they are not labled from the factory. The rear one will be done in the next year or so. I removed the six pack and rebuilt it on the bench. Quote Selected

While I was looking at it, there was a computer or ? that had a lot of wires going to it that was sitting at the top of the rails. It was easy to get to with no coach sitting on the frame. I thought about the poor sole that would have to be able to get to it if there was a problem. I took a picture of it. Will have see if I can find it. Quote Selected 2 Likes
Re: Working On My Six Pack Reply #88 – September 30, 2021, 10:55:43 am Here is picture. Looks like the computer for the transmission sitting on top. How would like to get to that one day. Sorry, picture was a little out of focus. 2016 Spartan K3 Chassis Quote Selected 1 Likes
