AIR PRESSURE TEST NOTE (12) Shut down engine (TM 9-2320-366-10-1). (13) Drain air tanks (TM 9-2320-366-10-1). (14) Disconnect input air hose from output 90 degree fitting of regulator valve. (15) Remove STE/ICE-R 0-1000 PSI transducer from output port of regulator valve. (16) Close LH and RH catwalks. NOTE Perform step (17) for M1089 RH 30K winch cable drum tensioner. AIR PRESSURE TEST (Cont) TM 9-2320-366-20-3 Change 1 2-2431 (26) Remove STE/ICE-R 0-1000 PSI transducer from output port of regulator valve. (27) Apply sealing compuond to threads of pipe nipple. (28) Install regulating valve on pipe nipple. (29) Install 30K winch tension Pneumatic valve assembly (para 17-30). (30) Close LH and RH catwalks. (17) Install M1089 control panel covers (para 17-20). (18) Pull out and turn knob on regulator valve fully counter clockwise. (19) Pull out and turn knob on regulator valve clockwise until STE/ICE-R shows between 55-65 PSI (380-440 kPa). (20) If 55-65 PSI (380-440 kPa) is present after adjustment, perform steps (23) through (30). (21) If 55-65 PSI (380-440 kPa) is still not present after adjustment, replace regulator valve (para 17-30). (22) Perform steps (12) through (17). (23) Shut down engine (TM 9-2320-366-10-1). (24) Drain air tanks (TM 9-2320-366-10-1). (25) Disconnect input air hose from input 90 degree fitting of regulator valve. (1) Disconnect air hose from adapter fitting on shuttle valve. (2) Disconnect air hose from 90 degree fitting on shuttle valve. (3) Remove two self-locking nuts, washers, screws, and shuttle valve from bulkhead. Discard self-locking nuts. (4) Position shuttle valve in vise. (5) Remove regulator valve from pipe nipple. (6) Install STE/ICE-R 0-1000 PSI pressure transducer in output port of regulator valve. (7) Connect input air hose to input 90 degree fitting of regulator valve. (8) Start engine (TM 9-2320-366-10-1) and allow vehicle to build air pressure. (9) Perform STE/ICE-R Test #50 and note reading on STE/ICE-R. (10) If 55-65 PSI (380-440 kPa) is not present, perform step (18) through (22). (11) If 55-65 PSI (380-440 kPa) is present, replace shuttle valve (para 17-30). Tag air hoses and connection points prior to disconnecting.
