HYDRAULIC CONTROL VALVE OPERATION The hydraulic control valves on the directional control valve bank
are activated by mechanical linkages from the operator's compartment and they, in turn, activate the hydraulic
functions of the vehicle.
Although the Bilge Pump is considered Not Mission Essential and will no longer
be supported with spare and repair parts, this manual contains troubleshooting
procedures For Your Information Only. See TB 43 0001-62-7 (dated Oct 98) for
Instructions to Isolate and Disconnect a Non-functional Bilge Pump.
This page and page 2-5 describe the functions of valves and circuits they activate. Refer to this page when
following the bilge pump, apron raise/lower, winch, and ejector valve circuits.
