HYDRAULIC HIGH-PRESSURE FILTERS

Two high-pressure filters located directly in front of the driver’s

compartment filter hydraulic fluid from the main hydraulic pump while it is enroute to the directional control valve

bank.

HYDRAULIC RESERVOIR

The hydraulic reservoir is located beneath the driver’s compartment and its check and

fill point is located in the driver’s compartment. It has a capacity of 32 gal. (121 L) of OE/HDO-10.

DIRECTIONAL CONTROL VALVE BANK

The control valve bank is located beneath the hydraulic high-pressure

filters. 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.

HYDRAULIC MANIFOLDS

Located in the hull, the manifolds route the flow of hydraulic fluid to the vehicle

components.

COMPENSATING HYDRAULIC PUMP

Located on the front of the transfer case, the pump 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 directional control valves to provide pressure to both left and right suspension controls.
