Air governor
The bird is due to come out of storage soon and I know I have some
extra things to work on. At the end of last year (still in good
weather) the air pressure would build to 150psi before the pressure
relief would kick in via the governor. Is it best to just replace it?
If so what is the easiest access (remove bumper, remove fan etc)?
Also, is it necessary to manually bleed the air tanks or does the drier
take care of all moisture? Also, where are the air tanks located?

I do not know where your tanks are on the SP. I'll tell you where mine are on
my WB-40, so you have an idea where to start. There are three tanks forward of
the drive axel near the Bendix air dryer which I had completely rebuilt
yesterday. The tanks and dryer are up under the floor in a not so convenient
location . A PIA to service. At the same time I had the mechanic install
lanyards on each tank..I did not find any significant water in the tanks. The
other tank is behind the generator above the front axel virtually inaccessible
but we got to it for a lanyard. Jacked up the coach and did it one handed. I
did not find any significant water in that tank either and it has not been
drained since I have owned the coach because I could not find it.
For info, the Bendix dryer on my 1990 is an AD-4 and I had to order the rebuild
kit.
Now if I can get my step to quit acting up, I will be ok.

Chuck You can get to the governor from under the bed. It is in the
back of the air compressor. I changed mine last year. They are only about
$40.00 so it is no big deal if it hasn't been changed for a while. I set mine
to
spit off at 120#. I think 150# is too high. You don't need that much
pressure.On mine the air tanks are front to back right behind the front axle &
in
front of the fuel tank. The first one is the front brake tank. the next is the
air throttle & air suspension tank. These two have a valve that can be
drained but I have never got any thing out of them The other two are above the
pass
thru compartment. There is a access plate that can be unscrewed & removed.
My tank on the curb side is the Wet tank & the one on the street side is the
rear brake tank.They have an expello valve that is automatic. Hope this
helps [4 air tanks]

Thankd Don,
Have you ever gotten anything out of the 2 center tanks?
Is any maintenance required on the air dryer and where is it located?

Chuck My expello valves went bad last year & I replaced them with valves
that has a cable on them & I run the cable to the side door. I knew they
were bad because they kept releasing air. If yours are working good I wouldn't
worry about them. That expello valve is made to automatic release any moisture
that gets by the air dryer. I guess that is why BlueBird put them up in that
covered area. They can't be got to very easy. I heard mine hissing is how I
found them.
The air dryer should be serviced if you haven't had it done since you
got the coach. If you crawl under by your water heater compartment & look up on
the curb side of the drive shaft you will see it. You will at least need a
new cartridge & a new spitter valve. I had a whole new dryer put on when I got
the coach 4 years ago. My garage said it was better at that time to put on a
new unit rather that rebuild it. Mine is a Bendix AD-9 . Look in Randy's
forum in the files there is some good info on them by John Finn.

You can also look in the Links folder of the forum for links directly
to the Bendix site for their manufacturer literature on all things
about air brake components, including spec sheets, rebuild sheets,
service bulletins, etc.
