SECTION III. PRINCIPLES OF OPERATION
1.13 FUNCTIONAL GROUPS
1.13.1 The hydraulic power supply may be conceived as five functional groups: An engine driven hydraulic
pump, a panel mounted grouping of instruments and controls, a hydraulic control manifold, cooling system and
reservoir assemblies.
1.13.1.1 Engine Driven Hydraulic Pump A dual hydraulic pump is directly mounted to a diesel engine. This
pump has two independent hydraulic output which are supplied from a common inlet
1.13.1.2 The engine operating instruments and controls are grouped together on the operators panel. The
panel also contains the hydraulic valves used to divert the flow of hydraulic fluid as required for operation.
1.13.1.3 A hydraulic manifold block mounted in the interior of the unit provides the pressure relief, thermal
regulation and flow control functions of the unit.
1.13.1.4 An engine driven fan draws cooling air from outside the unit across the cooler assembly. The cooler
assembly consists of two air to oil coolers mounted in tandem. The front cooler serves the hydraulic system
while the rear cooler serves the engine cooling system.
1.13.1.5 Two reservoir assemblies are located in the unit. The fuel reservoir content is indicated on a panel
mounted indicator. The hydraulic oil reservoir assembly consists of the reservoir, filter assembly, sampling and
drain valves and high oil temperature switch.
