Where to start with an air problem

[bluebirdfitz]

I just went out to move my 79 FC31 and could not get the air pressure up past
75, and
hence couldn't unlock my brakes. Everything had been working great, though I
haven't
used the bus in several months. I'm just wondering where a logical place to
start touble
shooting would be and what I should look for.

Thanks

Listen to the spitter on the air dryer. If the spring inside that keeps it
from blowing air constantly has deteriorated/weakened, it will constantly
release air and not let you build the expected pressure.

Morning John:

Not sure if you have an air drier in your year of Coach. If so, then try
removing the 1/4 inch line from the fitting going into the pressure relief
valve, if air starts to build then the relief valve needs a re build kit.
If no air drier then open the dog house and on the curb side of the CAT
toward the front, you will see your air compressor. Behind the air
compressor is where the air governor is mounted. Check the 2 1/4 rubber
hoses for air leaks there. If nothing found, replacing the governor is no
big thing and the cost should be around $20.00 at any truck repair shop,
for the part. Then check for an air leak on the spring break valve under
the right side of the dash by your knee. Just some ideas for you.

Safe travels,

If you have shop air and a place to hook it up to the bus ( may need
to make an adapter or hookup after compressor on bus), pressurize the
bus with shop air and listen for the leak. You wont have the cat
noise to compete with.

Thanks, Greg and Ralph

I do have shop air; I hadn't even thought of that! You guys have given
me some pretty logical starting places. I'll let you know how it goes.

John,

I had the same exact problem when I went to start my bird to take it
to Holland, Mi, back in Dec. It also had been sitting for about 6
weeks. After my initial panic, a slight tap with a hammer on the
governor (where the airline comes out) while the motor was running
cleared it right up. It was fine after that. My guess is that
something was slightly stuck from sitting and just needed a little
persuasion.
