Hydraulic Charge Filters. Two hydraulic charge
filters are located above the hydraulic pumps. Charge
pressure oil from the propulsion intake is routed into the
charge filters and back to the propulsion pumps. The
charge filters service the high pressure side of the
hydraulic system. The filters remove contaminants from
the hydraulic oil prior to the oil being sent to the return
manifold and other hydraulic systems.
Radiator. The radiator absorbs heat from the
engine coolant circulating through its coils. A flow of
outside air is forced between the radiator coils to
maintain normal engine operating temperature.
Hydraulic Oil Cooler. Hydraulic oil passes
through the hydraulic oil cooler before entering the
hydraulic reservoir. The oil cooler removes heat from the
oil, protecting it against thermal breakdown.
Hydraulic Return Filter. The return filter is on
the low pressure, return side of the hydraulic system.
Oil from separate hydraulic circuits is returned to the
hydraulic reservoir by way of the hydraulic return
manifold. All oil from the return manifold passes
through the return filter. The return filter protects
against contamination. A pressure gauge on the filter
housing displays filter pressure at the input to the return
filter. This gauge indicates a clogged filter by registering
an above normal system pressure.
