7.Close the HYDRAULIC SOV ENG 1 (61DE) (22)
(HYDRAULIC SOV ENG 2 (34DE) (23) ) circuit
breaker, located on the Overhead Circuit Breakers
Panel (271VE) in position B1 (B2).
FOLLOW ON MAINTENANCE:
1.Open the access panels 413F and 413D (423F and
423D).
2.Connect hydraulic test stand (AGE NO. 00262) to the
delivery and suction piping to the respective ground
test connections (Ground Service Panel) of the
system reservoir to be replenished.
3.Set up the test stand (AGE NO. 00262) with flow 5
gpm (19 l/min), pressure 900 psi (63 kg/cm
²
),
operating with stand reservoir pressurized and return
pressure 15 psi (1 kg/cm²).
4.Perform the reservoir filling by slightly increasing the
test stand return pressure until the level of 12.5 liters
is reached (read on the visual fluid level indicator on
the reservoir).
5.Reduce hydraulic test stand pressure to zero.
CAUTION
––––––––––––––––––––––––––––––––––
Avoid the hydraulic fluid spilling using a
clean cloth. This will prevent damage to
the equipment due to corrosion.

6.Cut the plastic wrapper (21), free the fitting from the
shield (20) and loosen suction flex hose (19) on the
EDP union (18).
7.Set up the test stand (AGE NO. 00262) pressure to
1200 psi (84.4 Kg/cm²).
