This crankshaft speed sensor monitors the rotational position and speed of the engine crankshaft. It provides a signal to the engine control unit, which uses the data to time fuel injection and manage ignition or combustion events. The sensor is mounted on the engine block, positioned near the crankshaft's reluctor ring or trigger wheel. A failed sensor causes the engine to run erratically, lose power, or fail to start. As an original AGCO component, the sensor body and sensing tip are manufactured to the same dimensional and electrical specifications as the original assembly, ensuring the correct air gap and signal amplitude without requiring shimming or adapter brackets. On installation, verify that the mounting surface is clean and that the sensor is seated fully before tightening the retaining bolt to the specified torque.
