Direction Control Valve (DCV) Bank
The control valve bank (Figure 2) is located beneath the hydraulic high-pressure filters (Figure 2). The control valves
in the valve bank are activated by mechanical linkages from the operator's compartment and they, in turn, activate
the hydraulic functions of the vehicle.
Located in the hull, the manifolds (Figure 2) route the flow of hydraulic fluid to the vehicle components.
Compensating Hydraulic Pump
Located on the front of the transfer case, the pump (Figure 2) provides pressure at a constant 2,800-2,900 psi
(19,306-19,996 kPa) to the SPRUNG/UNSPRUNG hydraulic operation. Capacity of this variable displacement pump
is 10 gpm (38 Lpm).
Main Hydraulic Pump
A fixed displacement pump is mounted on the rear of the transfer case. The pump pulls fluid from the hydraulic
reservoir and circulates it through the hydraulic filters at 13 gpm (49 Lpm), then splits the pressure at the DCVs to
provide pressure to both left and right suspension controls. (Figure 2)
