There was a flood, hurricane…… Locust, alien abduction…..I swear baby….you know I love ya…..it WASNT MY FAULT!
Yesterday became a blurt of neat things happening, Ruby came out of the big house for a little sunLooks like an ATF leak at the sender maybe……either that or Phillip just likes to lay under a diesel motor! I think he feels at home under there…….and yesterday I drove it……..Jared I think has the #1 name for this thing so far…….Mutcades……… We also have short time to make it presentable for the GMCMI convention coming next month…..stay tuned.
So today, my day off to recover I’m spending some time on the Electro-Level thing……I see so many coaches come in with sock air ride systems……we do these few thing and once again the Electro-Level, second generation air delivery system in our coaches can be reliable again.
Working with a really original 77 Palm Beach it too took forever to pump up to ride height. Not only was it annoying but sooner or later whatever is causing this will fail and there you will b….butt on the ground calling someone for help! You just don’t want that on the road so looking at providing reliable air for you rear suspension is a mission critical system and really needs to work…….
Looking at our assets, everything in the lower hall closet was spider web cover almost origin to the T’s except for a check valve and drier that so may coaches got back in the 80′ S. There’s a reason you need to take all that out too so read along
First thing is that cute ole blue faced V twin air compressor has to gook it’s “original” but in this case ….being a mission critical component….. ORIGINAL a single cylinder compressor was used in 73….the technology was not where it is today so they found they needed more CFM so the Hadley “Tuffy” compressor was rebadged and called GMC. We have a descent collection of these old girls on the shelf above our screw binseach one means there’s a coach with a better compressor out there. Today, technology has produced stronger, 100% duty cycle units that pull fat less current which is everything you need. The Puffy pulled over 30 amps. and had to rest after work (not 100% duty cycle. When u run out of air you run out of luck…..don’t base those hopes on a 45 year old pump! We install Viair and soon a new even more robust compressor….stay tuned……Next thing to change is if you have one of these water separators in your system……take it out!.back in the day and it made sense the idea of putting an air drier in line IS something you do on a shop compressor. Folks installed this so they didn’t have to dump the water built up in that tiny little tank the EL system used. Problem was it didn’t allow the “crud” to be dumped front the tank. Pulling off the spit valve GM put at the bottom of the tank tells the taleThe port is totally clogged no telling how thick the sludge layer is and being brown that’s rust!. I could spend an hour to clean out the pressure test the 45 year old tank……in this case I had a new stainless steel replacement tank. New is cheaper and better than spending the money on labor cleaning old parts…..better and a more reliable outcome. So clean it if you have no option…in this case I replaced itThe Stainless Steel check valve in one of the pics above has a high “crack pressure” so it eats up compressor pressie. The new Viair pump comes with its own proper check valve. Take that thing out!.
Next the original grey box air regulator is old…..really old for a regulator and its set at 80psi on and 120psi off. In travel mode, you may not kick on the compressor when you want to go up! You pressure must drop to 80psi for the system to come on. Its common to have to go down before you can go up! We install a new fixed( not variable like the original shop version used) set at 110psi on and 145psi off. This way you have a bit more reserve and the system will always come on when its needed. I mean like $35 ….why not.
Next, GM used black plastic air line fittings……need I say anything? Replace every line fitting….we use Parker brand “68p series” brass plastic Ferrell fittings. You cannot crush the air line when tightening! Hey, that’s a big deal!
If you address these issues on your Electro-Level system chances are you will be increasing the reliability of the system greatly and its usefulness. Of course there are MANY other issues your system might have…..this I guess you could call a place to start.
The adjustable rear suspension is an awesome driving aid. Go to our “video blog” page and find the video explaining how to use your air ride system….it ain’t just to level your coach when parked!
See that….I got it all out! I hope you got something out of it. I’m spending the rest of my day off working on MutcedesOh boy……see ya tomorrow.…….
