That may work, but not sure if that is the best. Typically the compressor turns off when it has pressurized an air tank to about 100 pounds. When the air bags fill and rear raises to correct height, the control valve next to the bags will shut off air to the bags. At this point the pump could still be running until it pressurizes the air lines to 100 or so pounds, which without a tank would probably be very quickly.

The main purpose of an air tank is to provide instant air to the system when needed without the pump needing to come on and build up pressure. I believe it was typical for AS to install a very small tank next to the compressor, see attached photo. That is was was in my mh. These tanks are very small and I dont think they could really provide much reserve compressed air. I think they may be called expansion tanks which I think serves the purpose of taking some of the moisture out of the air so as not to send that moisture to the air bags. The original small tank has a drain valve on the bottom to drain water out of the system. I installed a drain valve in the bottom of my new larger tank.

The old larger tank in my mh was installed as aftermarket to provide compressed air to a air hose fitting and to an aftermarket air horn located behind the front grill. I have discarded the small tank as well as the "freon" tank and I have installed a proper larger air tank. With this and the new air lines that dont leak, I can now use my air horn to honk at those idiots that seem to pull out in front on motorhomes on the roadway!

Air bags

[QUOTE=dadstoy;1099142]That may work, but not sure if that is the best. Typically the compressor turns off when it has pressurized an air tank to about 100 pounds.

My MH is 24' so that may be the difference......it is not as long or heavy as the 28'. The shop researched what was on the MH and put a similiar looking air bag on again. They told me I am better off not having a tank....They put in 60 pounds of pressure....we will see how it works.....also I got a look at the old gas tank (34 gal) not 40 like the book says (but my book was written for 28 or 31' models).

There was some pretty awful stuff (rust and gunk) in the gas tank plus it had been repaired. There was a hole on the bottom. They found a newer one in Orange County plus they fixed the gauge so I can watch it go down when I drive. They think that was keeping them from passing the smog test. Guess I will have to use 2 credit cards to fill the tank....some places limit the card to $75....perhaps we have a really big guzzler on our hands....surprise. Oh, yes, I suspected that...paula

Hi Paula. Well you are certainly getting closer to getting on the road. I have my fingers crossed for you on passing smog. I had issues with that too.

Success! My air compressor project is wrapping up. I got the electric installed and hooked up today. The compressor works like a charm. The Square D pressure switch is supposed to go on at 80 and off at 100 pounds...actual is 90 and 110, that is good enough for me!

My over night leak down test wasn't good but better than I had expected. Last night I manually pumped tank up to 100 pounds. This morning it was down to 40 pounds. I'll have to test to see if I have any leaks in fittings but I doubt that. I suspect it is the air bags/air bag control valve that is leaking. The bags seem to work ok so even if they leak, I will continue to use them as long as possible before I replace them.

I have two bulk head connectors on back order. I will install them when I get them so that the air line is not running directly through the side panel which would eventually cut the line. I also need to put a grommet in where I'm running the 12 volt wiring through the side panel.

In the near future, when dry, I will pull the compressor and prep and paint the bin.

I'll post a pic when my internet connection allows me to

So you really want to know?

She had been stripped of all her smog equipment in Florida...so she had to get it all back....which eventually involved buying another engine in order to pick the parts off like the air pump because she had to visually be put back as well as passing the smog.

I can give you a list of things but I don't know what was involved with the smogging part:
Rebuild carburetor
Rebuild radiator
Removed & replaced valve cover gasket set
Replaced left exhaust manifold assembly and both sides gaskets (big job)
Rebuilt heater core and replaced heater valve control cable
Install Air pump and Brackets, hoses, and belts (big job-part of the smog)
A/C rerofit
New batteries, cables and terminals
Rear differential service
Plus rear & front shocks, rear air bags, rear brake shoes and machine drums, new head lamps and assembly, sway bar bushings replaced, 6 new tires plus a used rim and tire for the spare (from a salvage yard) to name a few things. Oh, yes, I forgot, new/old gas tank (34 gal). There was a lot of rust on stuff....everything was frozen with rust.....even the bolts that hold on the spare tire.....

They test drove her today and went 80 on the freeway.....glad I wasn't there. They say she runs great and has a lot of pep....just need a loan to pay for the gas.....and the repair....I get to test drive her tomorrow...we still need a peace officer to verify the VIN and then a trip to the DMV to take in the title and pick up the license plates.....p

I'm trying to do all what you've done but bit by bit. I may be about a quarter way through of what you've done sans the smog gear!

Are you going to pull your Ambassador with it once you've done a couple of road trips solo?

I replaced the ground lug today. The old one was corroded and broken. It could have been a shocking experience.

Dean, where is your ground lug located? Something I guess I need to start looking for on the beast!
Thanks, Derek
