- repair the wiring (Ref. ASM 29-11/01).
(2) If the pressure shown on the gage of the Green reservoir is less than 25 psi (1.7236 bar):
- do a check of the clogging indicator on the Reservoir Pressurization Unit (1360GM).
(a) If the clogging indicator is out:
- replace the filter element (Ref. AMM TASK 29-14-41-610-002).
(b) If the clogging indicator is not out, or the fault continues after replacement of the filter element:
- pressurize the hydraulic reservoirs with a ground cart (Ref. AMM TASK 29-14-00-614-002).
- do a check of the pressure drop on the gage of the hydraulic reservoir.
NOTE : No pressure drop is permitted within 15 minutes at a gage
____ pressure of 50 psi (3.4473 bar)
1 If the air pressure drop is out of limits:
_ - do a leak check of the VALVE-MAN DEPRESS, G RSVR (1087GM).
a If the VALVE-MAN DEPRESS, G RSVR (1087GM) leaks:
_
- replace the VALVE-MAN DEPRESS, G RSVR (1087GM) (Ref. AMM TASK 29-14-16-000-001) and (Ref. AMM TASK 29-14-16-400-001).
b If the VALVE-MAN DEPRESS, G RSVR (1087GM) does not leak:
_
- do a check of the VALVE-AIR RELIEF, G RSVR (1005GM) for leaks.
- If the VALVE-AIR RELIEF, G RSVR (1005GM) has a leak:
- replace the VALVE-AIR RELIEF, G RSVR (1005GM) (Ref. AMM TASK 29-14-17-000-001) and (Ref. AMM TASK 29-14-17-400-001).
- If the VALVE-AIR RELIEF, G RSVR (1005GM) has no leak:
- do a check of the PRESS GAGE-G RSVR (1383GM) for leaks:
- If the PRESS GAGE-G RSVR (1383GM) has a leak:
- replace the PRESS GAGE-G RSVR (1383GM) (Ref. AMM TASK 29-14-15-000-001) and (Ref. AMM TASK 29-14-15-400-001).
- If the PRESS GAGE-G RSVR (1383GM) has no leak:

- do a check of all connections and components on the
reservoir for leaks.
- If you find a leak:
- tighten the related nut or replace the defective
component.
c If the fault continues:_
- replace the CHECK VALVE-RSVR PRESS, G (1388GM).
R
R 2_ If the air pressure drop is in the limits:
R a Depressurize the hydraulic reservoirs (Ref. AMM TASK 29-14-_
R 00-614-001).
R b Pressurize the reservoir pressurization system with the_
R left engine (Ref. AMM TASK 29-14-00-720-002), or
R c Connect an external pressure source:_
R - disconnect the reservoir pressurization hose (1674GM)
R from the HP bleed-air port of the left engine (Ref. AMM
R TASK 29-14-49-000-001)
R - connect an approved air or nitrogen inflation adaptor to
R the line end fitting of the reservoir pressurization hose
R (1674GM)
R - pressurize the reservoir pressurization system to
R approximately 15.2 bar (220 psi).
R d If the pressure in the reservoir does not increase to the_
R necessary value:
R - remove the RESTRICTOR- RSVR PRESS, ENG 1 BLEED (1392GM)
R (Ref. AMM TASK 29-14-13-000-001).
R - make sure that the RESTRICTOR- RSVR PRESS, ENG 1 BLEED
R (1392GM) and the filter are not clogged or damaged.
R - if necessary, replace the RESTRICTOR- RSVR PRESS, ENG 1
R BLEED (1392GM) (Ref. AMM TASK 29-14-13-400-001).
R e If the fault continues:_
R - do a check and, if necessary, repair the bleed air line
R in the left pylon to the Reservoir Pressurization Unit
R (1360GM).
R f If the fault continues:_
R - do a check and, if necessary, repair the remaining bleed
R air lines and components.
R g Stop the pressurization of the reservoir pressurization_
R system from the left engine (Ref. AMM TASK 29-14-00-720-
R 002), or
