i. Hydraulic Charge Filters

TM 5-3895-373-20 i. 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. j. 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. k. 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. I. 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. 1-5
