Air Leak help

[smquandt]

Last week asked about reverse feed to pressure coach from external
air. Worked and I found my air leak. See photo at Steve & Pat's 93
PT-40 photo is labeled "Leaking Air FTG" or
http://autos.ph.groups.yahoo.com/group/W...s/view/321
c?b=2

The valve is label #5 but I cannot find anything on the schematics
that corresponds to that, any idea what this controls?

Should I replace the entire line or just splice in a new fitting?
Complete replacement looks like job from HE@@.

Any help appreciated

Steve:

That is your suspension dump valve. Press on the grey ring, toward the
valve body and pull the black air line out. Clip the end of the air line
about 1/4 inch and re insert it fully into the fitting. If that does not
take care of it, then to the right of that valve will be 3 other fittings
with air lines going to it. Undo the last fitting and put it on the valve
then put the one off the valve back in the one you removed. Then find a
Parker Hanifin parts house and order some new fittings. Those fittings are
like the old Chinese finger holder toys, same idea.

Safe travels,

Steve,
I'll assume the leak is at the black plastic where it goes into the
white thingy. Try this...push the white thingy in and at the same time
pull out the black plastic line. Cut off a short piece of the black
line, 1/2". Push the line back in where it came from. If that does not
work, buy the brass/white thingy coupler and replace the bad one. Simple
job.

My guess is it controls one of the following...driving lights...left
front vent...right front vent...suspension up/down...tag up/down. On
ours there are five of those Clippard air switches. I haven't figured
out the 5th one yet. Might have something to do with the step, not sure.
The Clippard switches are the little yellow things attached to the air
manifolds. I see you have at least 4 of them from what I see in your photo.

Ralph,
When you crank and air up how long should it hold the air after you shut down.

Howard:

That time frame is sort of a crap shoot figure. Ideally, the air should
stay up for several days. Your front and rear gauges only tell you about
the air break tanks and not the "wet" tank. The air comes from the
compressor to the air drier. From there it travels to the wet tank and the
wet tank feeds the front and rear air break tanks. There is a one way in
line valve to prevent the air flowing back to the wet tank from both of
those air break tanks. Everything else, suspension, air step, step well
cover, seat slid, air ride seats and so forth work from the wet tank. There
is no gauge for the wet tank.

Safe travels,

Those air fittings are Parker PrestoLock fittings and Grainger carry's
them, but you havew to buy 10 of each. I'd like to find a place to buy
them 1 or 2 at a time.

Fix didn't work so I'll order fittings tomorrow from Grainger as
suggested. Thanks for all the quick replies!!
