Install crankshaft pulley, and tighten bolt to specification. To complete installation, reverse removal procedure.


  1. Position sensor assembly on bracket. Install 2 sensor screws, but DO NOT tighten. Install Crankshaft Sensor Gauge (T89P-6316-AH) to outside surface of one vane of shutter.
    NOTE: Gauge is magnetic and will conform to shape of vane.
  2. Push sensor housing inward to contact gauge. Tighten bolts to specification. See TORQUE SPECIFICATIONS. Ensure sensor is not overtightened. Overtightening can damage crankshaft sensor.
  3. Rotate crankshaft by hand to position shutter vane with gauge outside of air gap. Remove magnetic gauge. To complete installation, reverse removal procedure.
