Pilot Manifold The pilot manifold is the same as the "C" pilot manifold. The pilot manifold is located next to the main control valve group. The hydraulic activation valve (1) and solenoid (2) are located in the pilot manifold along with the swing brake solenoid (3) and the two-speed travel solenoid (4). The accumulator (5) will provide pilot pressure oil to the pilot system when the pilot pump flow is inadequate. Insufficient pilot oil flow to the pilot system may be caused by the following two reasons: - Implements are lowered while the engine is stopped and oil supply to the main control valves is stopped. - Combined implement/swing/travel operations.
