1. Remove hydraulic control valve manifold
assembly shields (WP 0519 00).
2. Install 0--4000 psi testing gauge assembly and
1/4--inch tee between port PMO of hydraulic
control valve manifold assembly and attaching
hose.
3. Install 0--4000 psi testing gauge assembly and
1/4--inch tee between port PMI of hydraulic
control valve manifold assembly and attaching
hose.
4. Start main engine, energize hydraulics, and set
engine speed to 1800 rpm
(TM 9--2350--292--10). Record gauge
pressures.
5. Shut down hydraulics and main engine
(TM 9--2350--292--10).
E

Inspect pilot valves and hoses from ports PMO and
PMI of hydraulic control valve manifold assembly to
hoist and main winch directional control valve
assembly ports PMO and PMI and return line from
tee between main winch safety level valves to
reservoir for restrictions and damage.
Remove restrictions. If
restrictions cannot be removed,
or if hoses are damaged, replace
(WP 0573 00). Verify fault is
corrected.
Are all hoses free of restrictions and damage?
Notify Direct Support
