Air Issue (Not A/C) and Motor Cleaning

[Kevin McKeown]

Greetings again,

Another little problem...when airing up the BB after sitting for a
few days (all air in tanks depleted), the pressure climbs and stays
at 30 PSI, and won't go any higher. I shut down the BB, and listen
through the open hatch underneath the bed, and hear air excaping
somewhere near the compressor. When it gets down to almost no
pressure, I hear a click, and the hissing abruptly stops. I start
up the BB again, and pressure climbs like normal up to the usual 125
PSI or so, and no hissing. This happens almost every time with the
same result.

I've kind of got used to the routine, but naturally I'm afraid of
getting stuck somewhere with only 30 pounds of air pressure (can't
release the brakes, suspension dumped, etc). Any ideas? I know
there must be some kind of valve that is sticking, but I can't find
it in all that mess of hoses and wires. Any sugestions?

Also, looking down through the engine hatch underneath the rear bed,
the engine is pretty gunked op with old oil, dirt, and the
usual "road cake". Can I hurt anything by soaking it with engine
degreaser (Sam's Club Purple Cleaner), and hitting with a hose or
pressure washer? I'd like to get the snail shells, mouse poop, and
the grime washed off so I can see what I'm looking at. The top of
the motor makes a nice dining room for the neighborhood little
critters, and I guess the snails are tasty but their shells aren't.
OK to pressure wash it clean?

Thanks, like always....

At the bottom of your air drier is a valve that purges water. I call it a
spitter as it performs each time your air compressor cycles to its max
pressure. Over time the spring that is supposed to closed the valve gets
tired. A rebuild kit for the spitter valve is about 11.00 dollars, its a
quite simple procedure. Should not have to remove the air drier to do this.
All of this is based on having an AD-2 Bendix air drier.

Just a little more information that may help relative to parts for
the Bendix AD-2 air dryer.

Check valve kit: Bendix 00287298 cost $6.93

Purge valve kit (spitter valve) Bendix 00287053 cost $13.94

Dissicant cartridge Bendix 0010900 cost $32.00

I got all of mine from NAPA although there are a lot of places on the
internet that you can buy them at.

Kevin, I have tried to email you and it was returned regarding the
CORRECT NAPA part #'s for the rebuild of the AD-2 air dryer. If you
email me cme4boatsataoldotcom I will give you the NAPA numbers and
you should be able to find the whole rebuild and descicant cartridge
replacements for the air dryer.

Kevin,

I think there may be some confusion between "NAPA" part numbers versus
"Bendix" part numbers for the AD-2 Air Dryer.

The part numbers listed in the prior response which is being referred
to by Scott, are in fact the correct "Bendix" part numbers right off
the Bendix spec sheet for the AD-2 dryer. You can go to
http://www.bendix.com/products/ViewLiter...=AirDryers
pull down menu - Page 13 has all the Bendix part numbers.

I think even a NAPA counter guy could cross-reference the Bendix part
number to one of their NAPA part numbers if need be. On the other
hand, I have stood at a NAPA store for half an hour with the old NAPA
part in hand, while they tried to find the NAPA Part Number printed on
the old part.......

The prices listed for the Bendix parts in the original post are about
what I have paid at real truck parts houses, but they have usually
been asking 2x those prices at the NAPA stores I have visited.
Needless to say, I buy from the big truck parts counters.

Prior message meant to say:
When you go to the Bendix page, look under "AD-2 Air Dryer" for the
Service Data Sheet in the pull down menu .... and then go to page 13
for all the Bendix part numbers.

Lost that whole line when the message posted.
