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 pressure/flow
kit from circuit B tube.
(16) Disconnect circuit B pressure hose from
pressure/flow kit.
(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 pressure/flow kit.
(4) Connect pressure hose from pressure/flow
kit to circuit B tube.
(5) Completely open pressure/flow kit load valve.
(6) Start and run engine until ormal operating
temperature is reached (TM 9-2320-365-10).
(7) Engage PTO (TM 9-2320-365-10)
(8) Set engine speed with manual throttle
control to 1,350 rpm.
(9) Slowly close load valve on pressure/flow kit
until 2,500 psi (17,238 kPa) is reached and
note flow on pressure/flow kit.
(10) If flow is not 15-18 GPM (51-70 lpm) at
2,500 psi (17,238 kPa), replace single stage
hydraulic pump (para 16-5).
(11) Open load valve on pressure/flow kit.
(12) Decrease engine speed with manual
throttle control.
