Are all hoses free of leaks, restrictions, and damage?
CONTINUED FROM STEP O
no
yes
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
corrected.
Q
