CAUTION
WARNING
(14) Shut down engine (TM 9-2320-366-10-1).
(15) Disconnect pressure hose from hydraulic tester
at pressure port (P) of winch control valve.
(16) Disconnect pump supply pressure hose from

(17) Connect pump supply pressure hose to port (P)
on winch control valve.
(18) Remove drain pan from under winch control
valve.
(1) Position drain pan under winch control valve.
(2) Disconnect pump supply pressure hose from
pressure port (P) on winch control valve.
