Hydraulic tank (1) is located directly behind the operator's compartment. Hydraulic tank (1) contains two filter elements (4) and the hydraulic tank (1) is not vented. Pressure is relieved when the cap is loosened. Pump suction ports (9) and (7) provide outlets for the oil to the implement and secondary steering pumps. Case drain return port (10) and implement return ports (8) combine the oil into the tank manifold. The manifold routes the oil through the bottom and through the inside of the oil filters. The oil filters are positioned partially below the oil level in order to reduce turbulence.
If the filter elements become full of debris, oil cannot pass through the elements. The restriction of oil flow causes a pressure increase which opens bypass valve (6). When the bypass valve opens, oil is allowed directly into hydraulic tank (1). When oil bypasses filter element (4) debris in the oil will cause damage to other system components. Correct maintenance must be used. This ensures that the filter elements do not stop the flow of clean oil to the hydraulic system.
