| Subject: | CJ-6A Emergency Air Pressure |
I am unable to find the preferred pressure and acceptable decay rate (if any) for
the air pressure on the emergency side of the air system. Decay rates are listed
in the maintenance manual for the normal pressure side. Any one have these
details? Thanks. Coop. :D [Question]

Coop, there should be no loss of emergency air.
On the starboard side of the fire wall, adjacent to the start solenoid, there are
a set of check valves. The one on the upper side leads to the emergency tank.
The small rubber disk inside it has probably deteriorated resulting in a drop
in emergency air when the engine is not running.
Doug Sapp has the appropriate overhaul kit. It's any easy fix.

Also, check the gauge fittings. Ours leaked down several years ago and it
was a crack in the fitting input. Only an ultrasonic leak detector found i
t. Trivia - of the 4 screws securing the emergency gauge, 3 are identical
and one is slightly different/longer. Be sure to mark positions when remov

No need to remove any screws. It is a clamp mounted instrument. The
different one is the clamp screw, loosen that, give the screw driver a
light tap and lift the gauge out of the hole.
I agree - zero leakage for the emergency system. It is a rerlatively small
system and easy to find the leak source (or sources).

If you remove the air pressure gauge (any one of them) remove the
fitting from the back of the gauge. Take a close at the very small hole
that is the input of the gauge and see if it full of rust and crud. It
is a common problem and makes the gauge lag behind pressure changes. A
small wire drill can be used to CAREFULLY remove the rust.
