Are all hoses free of leaks, restrictions, and damage?
CONTINUED FROM STEP O
Inspect the following hoses for leaks, restrictions,
and damage: hose from charge pump port A1 to
filter valve manifold check valve (CV6) port CH1;
hose from charge pump port S1 to filter valve man-
ifold port CH2; hose from front pump port S2 to
filter valve manifold port CH2; hose from filter
valve manifold port CH3 to hoist and main winch
directional control valve port R; hose from filter
valve manifold port CH2 to hydraulic control valve
manifold assembly port AWR and hose from hy-
draulic control valve manifold assembly port AWR
to port C of crossport relief/anti--cavitational valve.
Tighten leaking connec-
tions and remove re-
strictions. If restrictions
cannot be removed or if
hoses are damaged,
replace (WP 0565 00,
WP 0568 00, and WP
0573 00 or WP
0572 00). Verify fault is
Is pressure at CH4 60--140 psi?
1. Start the APU (TM 9--2350--292--10).
2. Place system selector valve in the AUX
position and observe pressure at port CH4 of
filter valve manifold.
3. Shut down APU (TM 9--2350--292--10).
Notify Direct Support
Replace charge relief
valve on filter valve
manifold (WP 0550 00).
Verify fault is corrected.
