Are all hoses free of leaks, restrictions, and damage?
CONTINUED FROM STEP C
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 0568 00,
WP 0565 00, and WP
0573 00). Verify fault is
Does pressure gauge at CH4 read 60--140 psi?
1. Start the APU (TM 9--2350--292--10).
2. Place system selector valve in the AUX
position and observe gauge at port CH4 of filter
3. Shut down APU (TM 9--2350--292--10).

Replace charge relief
valve on filter valve
manifold (WP 0550 00).
Verify fault is corrected.
