WARNING
Wear appropriate eye protection when working
under vehicle due to the possibity of falling
debris. Failure to comply may result in
injury to personnel.
CAUTION
Maintain engine rpm at 1,250-1,450 rpm while
perfoming pressure and flow test. Failure to
comply may result in damage to equipment.
HYDRAULIC FLOW AND PRESSURE TEST
(15) Disconnect pressure hose from hydraulic tester
from circuit B tube.
(16) Disconnect circuit B pressure hose from
hydraulic tester.
(17) Connect circuit B pressure hose to circuit
B tube.
(18) Remove drain pan from under winch control
valve.
(1) Position drain pan under winch control valve.
(2) Disconnect circuit B pump pressure hose
from circuit B tube.
(3) Connect pressure hose to hydraulic tester
(4) Connect pressure hose from hydraulic tester
to circuit B tube.
(5) Completely open hydraulic tester load valve.
(6) Start and run engine until normal operating
temperature is reached (TM 9-2320-366-10-1).
(7) Engage PTO (TM 9-2320-366-10-1).
(8) Increase engine RPM to 1250-1450 RPM
(TM 9-2320-366-10-1).
(9) Slowly close load valve on hydraulic tester
until 2450-2600 psi (16893-17927 kPa) is
reached and note flow on hydraulic tester.
(10) If flow is not 15-18 GPM (51-70 lpm) at
2450-2600 psi (16893-17927 kPa), replace
three stage hydraulic pump (para 16-92).
(11) Open load valve on hydraulic tester.
(12) Decrease engine speed
(TM 9-2320-366-10-1).
(13) Position PTO switch to off (TM 9-2320-366-10-1).
(14) Shut down engine (TM 9-2320-366-10-1).
