Air pressure - williamcharrison - 07-03-2007 05:17

I recently replaced the air governor on my 3208 engined BB because
the old one let the pressure build to over 140psi as indicated on the
dash gauge. The new one has an adjustment range of 105-120psi
but the air pressure still builds to an indicated 145psi. is
there something else that could cause this problem? (I checked to
make sure that the exhaust port was free).

William:
Is your air pressure gauge accurate?

Air pressure - Ray - 01-19-2011 06:59

Hey Guys,
I have been a silent observer on here for over a year. I read every post that
comes out and appreciat all the insight. It has been an immense help for me.
Whoever started this ought to receive a peace prize or something
comparable.Recently, there was a discussion about air pressure. It prompted me
to run a little test by turning my auxiliary compressor on and airing up my
system. I wanted to check and see if any obvious leaks had developed since I've
been sitting for 4 months. My gauge on the dash is at about 70 for both the
green and the red needle after a week. However, it created a small issue for me
in that my front step came in while I was ruining the compressor. It didn't come
all the way in, it just hangs in limbo. It won't stay in and won't stay out. I
can easily push it in and out with my hand. I tried the step extend switch and
it has no effect. It's a bit dangerous climbing in and out of this thing on a
swinging step... Help if you can... Thanks

Ray, I would start the coach, air up the system and see if the step will extend
and retract. My step will extend when the system air pressure starts to drop
off. Use the step override switch to keep it extended while parked. David Hanvy

Ray: First of all, you should get more than 70 psi. You either have a leak or
your governor is not working correctly. Try kicking the step when the air is at
its highest point. If it then either retracts or extends, that is a good
indication that your leak was at the step. There are a couple of air pressure
regulation valves that frequently go bad. One is in the rear next to your
schraeder valve in the engine compartment assuming you have a pusher. If its
leaking you will sure know it. The other is used to regulate the tag axle
pressure and it is on the cross member above the rear axle.

Hope that helps.

Like any commercial vehicle with air brakes, the tanks should run between 110 and 120 psi under every condition. If you do not show this, your unloader for the compressor is bad and no, your step will not work under 90 psi. check for 120psi at the rear schraeder valve, be sure your dryer is not plugged up and drain your tanks once a year if needed for moisture.
