a. Test. (figure 3-3)
(1) Using suitable hydraulic test equipment, connect valve as shown in illustration with fiitered input
of 210 gpm at 2,650 psi (182.71 kg/sq cm).
(2) Measure the pressure at the front winch and rear hydraulics output ports, and verify fluidis being
directed to the ports selected.
(3) Using hydraulic gage check that pressure loss from either output port does not exceed 200 psi
(13.79 kg/sq cm) at a fluid temperature of 111 °F to 140°F (43°C to 60°C).
