This low oil pressure sensor monitors the hydraulic pressure at the pump cover. It sends a signal to the operator display or control unit when pressure drops below the calibrated threshold, indicating a potential lubrication or pump failure. A failed sensor may not trigger the warning, allowing the engine or transmission to operate under low pressure without the operator's knowledge. The sensor is manufactured by AGCO to match the original thread and sealing geometry of the pump cover housing, ensuring the signal is accurate and the connection is leak-free. On reinstallation, ensure the sealing washer is replaced and the sensor is torqued to specification.
