BILGE PUMP CONTROL VALVE (24)
When activated, pressurizes 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 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 the 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).
