5. Position the hot sensor plate so that the tab on the sensor plate aligns with Groove (Y) on the crankshaft gear.

6. Push the sensor plate onto the crankshaft gear until the back of the sensor plate contacts the front of the crankshaft gear. Hold the sensor plate on the crankshaft gear in this position until the sensor plate cools and the sensor plate is properly seated.

7. Use a feeler gauge in order to measure the clearance between the back of the sensor plate and the front of the crankshaft gear. The measurement should be taken in three places and the clearance should not exceed 0.25 mm (0.010 inch).

Note: Steps 4 through 7 are for Engines (S/N: 3CS1-11999) and (S/N: 2KS1-39999) that have the sensor plate.
