QUICK-DISCONNECT COUPLING HALF MAINTENANCE (Contd)
LEAK TEST
1.
Start engine (TM 9-2320-361-10) and buildup air pressure.
2.
With dummy coupling (4) locked to coupling half (5), turn valve handle (1) to open position.
3.
Test dummy coupling (4) and coupling seal (3) for leaks by coating with soapy water. Check if
coupling seal (3) is leaking by watching for air bubbles. If leaking or damaged, replace coupling
seal (3).
4.
Turn valve handle (1) to align with coupling half (5).
5.
Stop engine (TM 9-2320-361-10).
REMOVAL
WARNING
Do not disconnect air couplings before draining air reservoirs.
Small parts under pressure may shoot out with high velocity,
causing injury to personnel.
1.
Remove dummy coupling (4) from coupling half (5).
2.
Remove coupling half (5) from nipple (2).
NOTE
Perform step 3 only if coupling seal is damaged or leaking.
3.
Remove coupling seal (3) from coupling half (5). Clean all coupling seal (3) remains from coupling
half (5).
INSTALLATION
NOTE
Perform step 1 if coupling was removed. Wrap male pipe
threads with antiseize tape before installation.
1.
Install new coupling seal (3) in coupling half (5).
2.
Install coupling half (5) on nipple (2).
3.
Install dummy coupling (4) on coupling half (5).
4.
Connect battery ground cable (WP 0126 00).
5.
Start engine (TM 9-2320-361-10), build up air pressure, and check for leaks.
6.
Release parking brake and remove wheel chocks (TM 9-2320-361-10).
