4. Disconnect the Sensor:
   • Locate and disconnect the speed sensor connector to isolate the sensor.
     
5. Remove the Old Sensor:
   • Carefully remove the crankshaft speed sensor from the engine.
     
6. Set the Correct Shim Thickness:
   • Use the 88800031 Setting Tool to measure and determine the correct shim thickness needed for the new sensor. This ensures proper clearance and alignment with the flywheel.
   • Install the setting tool and tighten the lock screw.
   • Remove the tool and verify the distance to the flywheel’s tooth is correct.
     
7. Install the New Sensor:
   • Insert the new sensor with the correct amount of shims and a new O-ring.
   • Note: Clean the sealing surface on the sensor and apply a sparing amount of oil to the O-ring to ensure a good seal and ease the installation.
     
8. Reconnect the Sensor:
   • Reconnect the speed sensor connector ensuring it is secure and properly aligned.
9. Reassemble the Machine:
   • Reinstall the pump room covers, ensuring they are securely fastened.
10. Test the Installation:
    • Turn ON the battery disconnect switch.
    • Start the machine and check the function of the new crankshaft speed sensor to ensure it is operating correctly.

Final Check:

After completing these steps, it’s important to monitor the sensor’s performance to ensure there are no issues with readings. If the sensor isn’t functioning as expected, recheck all connections and installation parameters.
