Bob,
If you are talking about the two cylinder GMC/Hadley/Dana compressors a test would be easy and straight forward. Just dummy what ever parts you have
to dead head (that and nothing else) the pump air out into any pressure gauge. Don't worry about control switches or anything, it won't need to run
long enough to hurt anything.
When you put power on it, a good pump will instantly make 100PSI, and be at 120 only moments later. A new pump will get to 140 in short order. This
should be about a one minute test. It will take you longer to assemble the parts than it does to run the test.
The Hadley/Dana pumps are effective, but they are not long lived. Fortunately, they are easy to rebuild and JimK has the kits.
See you in Shawnee

He doesn't have the twin cylinder compressor.
He has two separate compressors. He has a 78 Royale

Justin,
You have missed the same point I did. His coach is an Electro-Level II. The compressors (2ea) are not just compressors. They are pumps and valves
in a single unit (of which he has two). I have never had hands on one long enough to test it or even understand all about how it works.
For the short term, Schader valves and shut-offs is a good solution. A local GMC friend said he just bought a replacement. I did not ask how much or
where, but Cauglhan's Cinnabar would be my first guess.

The compressor (S) there are TWO of them in a EL II. are self contained
units with a permanent magnet motor about the size of a heater blower
motor. As the permanent magnets age, they lose some of their magnetism.
Then, they are not as good at pumping air. Bearings, armature, and other
internals also wear out. They will still run, but draw a bunch of current,
and are slow. When they deteriorate enough, they will not maintain ride
height.
Decision time. Find newer compressors and retrofit. Or, Vi-air. Or,
wireless, remote controlled, replacement system. Not much of a fix for
those original compressors, though.

Haven't had a reason to run the compressors in the past 17 months that we've owned it. Or the 4 trips we've taken. It just would be more convenient to have the compressors to put a small amount of tilt in when taking a shower for the floor drain. 1/4" in 3 feet would do it. Been just using a 1 by piece of wood under the left tire. Just haven't wanted to deal with the issues that I knew I had. The two compressor system was implemented about the first of Jan 1978. A lot less parts, and no tank. I don't understand the little 1/16 ID ( at best ) tube that come out of the compressor discharge port. To the 12 volt valve. So at this point. The bags are up. The board will do the job. Bob Dunahugh
Both compressors aren't putting out much. One at 35 PSI. The other's at 55 PSI. So I need some advice on a simple way to safely test the extra one's I have. As I have 4 extras. The complete extra system has some extra stuff with gauges that Cinnabar sales. Bob Dunahugh Late 78 Royale

Schraders are available at Ace Hardware for $2.00 or $3.00 each. You do not even need the shutoffs. Just screw in the schraders. If you insist, on
shutoff valves, also get them at Ace or Menards or Lowes.

Pulled the compressor out of the burned 78 GMC. Runs. But appears that the timing cogged belt has the two cylinders out of time to each other. That's simple to fix. Thus I now have two of the 2 cylinder compressors. Anyone ever just use two of the earlier compressors? Bob Dunahugh

Bob,
To use anything other than the OEM Electrolevel II style compressors,
you'll have to add external control valves. The originals have those
internal. Not a simple compressor swap. Basically, you'd have to revert
to the Electrolevel I design.
Too bad.

I have replaced the OEM ElectroLevel II compressors with two Viair compressors. Since (as noted by others) the exhaust valve and air dryer was
integral to the GMC compressors, those units had to be obtained & plumbed into the system. The only problem I had was getting the exhaust solenoid
valves in without leaks at the fittings. I found out that there are pipe threads and then there are pipe threads! It probably would not have been a
problem if I had chosen a higher quality solenoid, instead of the cheap imported ones. The answer to getting the two "pipe threads" to seal was to
use Loctite 565 thread sealant.
The result is a very fast raising coach, actually faster up than down, since I need to fine tune the exhaust orifice size.
I considered a wireless system, but my OEM bags on the heavy stretch need more than 100 psig to achive full raise in a campground.

Ken B. About 14 years ago I put a new belt on. I marked the sprockets with a magic marker as to the piston timing. That's how I knew the timing was off. So now I know why the raising was getting slower over the last few years.
Ken. I have the Quad bags from Applied. So the valves, and Schrader's are there. Could just use my extra Older GMC compressor with a power cord, and hose. Bob Dunahugh
Pulled the compressor out of the burned 78 GMC. Runs. But appears that the timing cogged belt has the two cylinders out of time to each other. That's simple to fix. Thus I now have two of the 2 cylinder compressors. Anyone ever just use two of the earlier compressors? Bob Dunahugh
Haven't had a reason to run the compressors in the past 17 months that we've owned it. Or the 4 trips we've taken. It just would be more convenient to have the compressors to put a small amount of tilt in when taking a shower for the floor drain. 1/4" in 3 feet would do it. Been just using a 1 by piece of wood under the left tire. Just haven't wanted to deal with the issues that I knew I had. The two compressor system was implemented about the first of Jan 1978. A lot less parts, and no tank. I don't understand the little 1/16 ID ( at best ) tube that come out of the compressor discharge port. To the 12 volt valve. So at this point. The bags are up. The board will do the job. Bob Dunahugh
Both compressors aren't putting out much. One at 35 PSI. The other's at 55 PSI. So I need some advice on a simple way to safely test the extra one's I have. As I have 4 extras. The complete extra system has some extra stuff with gauges that Cinnabar sales. Bob Dunahugh Late 78 Royale

I have cheapie Vlair knockoff from Harbor Freight that I carry in the coach. It doubles as a tire inflater. I only used it once when for some
reason a brass fitting in the air system cracked during the GMCMI rally in Wisconsin.
