Another compressor problem - erniecarpet@... - 12-30-2007 07:06 John, on my previous coach, 84 35FC, the air dryer was located in the middle of the coach just inboard of the steps.

They started incorporating them in the early 80s models. You should have a spitter assembly attached to the bottom of your primary air tank. It spits air and oil from it on a low volume basis. Sometimes makes a mess. You also should have a valve at the bottom of all three air tanks that should be opened occasionally to drain any moisture and oil that accumulates in the tanks.(Also making a mess).

Checked and the belt is Ok and the compressors seems to be turning Ok. Is there a solenoid or a switch which activates and deactivates the compressor. I get about 30lbs on the air gauge but no more. The only other clue is that when the compressor is running normally it makes enough noise that I can hear it and it is not doing that. Don't know beans about what I am dealing with but any help or suggestions as to what to look at or for would certainly be appreciated.

Often of you cover the outlet on the bottom with the palm of your hand with the engine running, it will fix itself for that trip. If you find this happening, you need new relief valve.

The compressor will provide air to the wet air reservoir -- it then passes through the air dryer to the dry air reservoir. Most BBs use a Bendix AD-9 system -- a Google search will find some photos. They look sort of like a big oil filter (but are attached to the air lines). If you're in cold weather, another common problem is for the step to be 'stuck' in a partially extended position, sometimes this leaves the air valve open and venting, keeping pressure from building up.

On my 82 FC is was just about at the center (length and width) of the underside. Your coach is older, it may not have one. The dryer is the thing that makes the "pssshh" sound as it spits air when the compressor reaches its governed PSI. Follow the sound.

My 81 FC-33SB did not have one, however my friends 83' had one from the factory. I'm sure others may chime in on this, but I do think it was a factory addition around 83.

Make sure if you change it, to install a new one as they are only a few more dollars than a remanufactured governor. Check out this page on my web site for more information and the location of the governor itself on an FC model 'Bird. http://www.pbase.com/iamflagman/image/68481426 JOHN FINN 1982 FC35RB BLUEBIRD WANDERLODGE HOPKINS, SOUTH CAROLINA VISIT THE FINN'S INN EXPRESS REMODELING ADVENTURE AND TECH.

I can usually tell by the sound if my compressor is running/working as opposed to bypassing. If yours is not working then I would suspect the governor. It is unlikely that the compressor would fail suddenly. Other problems may include broken/leaking air lines, failing pressure regulators, or other leaks in the system. Since the front and rear brake tanks should be independant, I would look for a leak in the primary/wet tank circuits. On my coach I found tons of oil sludge in the tanks and I suspect no one ever drained them. The sludge caused some of the inline regulators to stick and cause low pressure problems. Mine seemed to clear up with repeated attempts to charge the system.
