Anyone had the need to replace one of their Electro Level II compressor's??
If so, what did you obtain?

Yesterday, I found that my right side compressor is only able to develop 80
psi pressure. Two weeks ago, although slow, it produced the 120 psi I use
to inflate my four air-bag suspension. Don't believe it is one of the
solenoid valves.

Guess I'll have to look at one of the Thomas pumps discussed here back in
January, since Cinnabar wants $343.00 for a replacement pump. Ouch.

Paul,

You may have already gotten the information you need on this. I have just
returned from a GMC Classics rally and saw your post.

A compressor from a Cadillac Seville, '78 -85, with the touring suspension
(most had this) has the same compressor that is used with Electrolevel II.
Also the height sensor is the same. I paid $20 each for 2 spare compressors
and $5 each for 4 height sensors. If you go scavenging, I recommend you test
both the sensors and the compressors before you buy them. You can use either
a 12 volt battery or a 12 V power supply to test the sensors. You will,
however, need the battery for the compressor to prove that it is building
pressure (you can use the one on your car). You can use the wiring diagram
to simulate the GMC Mh installation for testing the sensors.

Paul, before you purchase a new compressor, check the internal solenoid
valve in the head of the compressor. If the solenoid is leaking, you will
lose air pumping capacity, and if the leak is large enough, the compressor
will not be able to reach full pressure. It could be the head gasket, but
that's not likely to give you a leak large enough to bother the compressor.

You can check the solenoid by using a piece of plastic or rubber tubing.
Place one end close to your ear, and move the other one around the head of
the compressor. The solenoid exhausts below the head, where it extends over
the cylinder. The ignition key should be on for the test, and of course,
you want the compressor to stop running so you can hear any leak.

I replaced mine about a month ago. (I got them from Gateway for $61.50 each.
Not cheap, but much better than the cost of replacing the compressor) If
your compressor has failed, we will all be listening eagerly for your
solution.

By the way, when you make your repair(s) check the main solenoid valve
between the compressors and the air bags. I have heard that most are
installed backwards. Mine were. The arrow on the side of the valve should
point AWAY from the bag not away from the compressor.

Good luck.

paul I got a rebuild kit from Gateway for $48.50 and a brand new Dana
conmpressor for $193.50

Thomas:

Not sure you're familiar with the Electro Level II system, used in the mid+
78 model coach's. It doesn't use the same compressor as your's does (Dana).
It uses two small compressors (one for each side), without an air tank.

Cinnabar tells me there is no rebuild kit for them.

The Firestone pump is a Thomas 315 compressor. Darren
