CMCAC Pressure Test
Refer to Figure 97.
1. Remove the air ducting from core.
2. Plug the core inlet opening.
3. Insert a plug with an air line adapter in the
core outlet opening.
Charged air cooler pressure fixture J 41473 can
be used on coolers with the flange connections.
4. Connect a safety chain or cable to both
plugs.
Stand clear of the plug area when system is
pressurized.
5. When plugs are secured, attach an air line
(fitted to a pressure regulator and gauge) to
the air line adapter in the core outlet
opening.
6. Pressurize the system to 30 psi (207 kPa).
7. Shut off the air source. Pressure should not
drop more than 5 psi (35 kPa) within
15 seconds. Repair or replace the core if
pressure drop exceeds specification.
8. Carefully release pressure from the system.
9. After repairing or replacing the core,
reconnect ducting. Tighten clamp nuts until
clamp spring is fully compressed.
When the spring is fully compressed, the torque
applied on the nut is generally between
40–55 lb-in (4.5–6.2 N
폷
m).
