Crankshaft Position Sensor: Adjustments

Harmonic Balancer Assembly:

1. Before adjusting crankshaft sensor rotate harmonic balancer using a 28 mm socket. Rotate the harmonic balancer until the interrupter ring(s) fills the sensor slot(s) and edge of interrupter window is aligned with edge of the deflector on the pedestal.
2. Insert adjustment tool J36179 or equivalent into the gap between sensor and interrupter ring. If gage will not slide past sensor on either side of interrupter ring, the sensor is out of adjustment or interrupter ring is bent. this clearance should be checked at three position around the outer interrupter ring, approximately 120~ apart. If found out of adjustment the sensor should be removed and inspected for damage.
3. To adjust crankshaft sensor loosen the pinch bolt on the sensor pedestal and insert tool J-36179 or equivalent into the gap between sensor and interrupter on each side of interrupter ring
4. Make sure interrupter is sandwiched between blades of adjustment tool and both blades are properly inserted into sensor slot.
5. Torque sensor retaining pinch bolt to 30 inch pounds while maintaining light pressure on sensor against gage and interrupter ring. Check this clearance at three different position approximately 120~ apart. If interrupter ring contacts sensor at any point during rotation of harmonic balancer, the interrupter ring has excessive runout and must be replaced.
