HYDRAULIC SYSTEM -- CONTINUED

Bilge Pump Control Valve (24)

When activated, pressurized bilge pump circuit at 1,450--1,550 psi (9,998--10,687 kPa) and starts bilge pump

action.

Right Pump Control Valve (13R)

Receives oil flow from the main hydraulic pump and maintains pressure at 3,950--4,050 psi (27,235--27,925 kPa)

for right--side hydraulic functions.

Left Pump Control Valve (13L)

Receives oil flow from the main hydraulic pump and maintains pressure at 3,950--4,050 psi (27,235--27,925 kPa).

Right Suspension Control Valve (3R/17R)

Port 3R, front bottom of valve, raises the right front--side of vehicle. Port 17R, above port 3R, lowers right

front--side of vehicle. Relief valve is set at 3,450--3,550 psi (23,788--24,477 kPa).

Left Suspension Control Valve (3L/17L)

Port 3L, front bottom of valve, raises the left front--side of vehicle. Port 17L, above port 3L, lowers left front--side

of vehicle. Relief valve is set at 3,450--3,550 psi (23,788--24,477 kPa).

Apron Raise/Lower Control Valve (19/20)

Port 19, front top of valve, actuates circuit and raises apron. Port 20, below port 19, actuates circuit and lowers

apron. Relief valve No. 19 is set at 4,450--4,550 psi (30,683--31,372 kPa) and relief valve No. 20 is set at

1,950--2,050 psi (13,445--14,135 kPa).

Winch Control Valve (C1/C2)

Port C1, front bottom of valve, actuates circuit and moves cable out of winch Port C2, above port C1, brings cable

into winch. Relief valve is set at 1,950--2,050 psi (13,445--14,135 kPa) on the winch.

Ejector Control Valve (21/22)

Port 21, front top of valve, actuates circuit and moves ejector forward. Port 22, below port 21, actuates and

moves the ejector back. Relief valve is set at 1,950--2,050 psi (13,445--14,135 kPa).
