For proper operation, the condition and installation of the sensor must be correct. If the condition or the installation of the sensor is suspect, use the following procedure.
- Remove engine speed/timing sensor (1). Inspect the condition of the end of the magnet. Look for signs of wear and contaminants.

- Clean any debris from the face of the magnet.
- Check the tension of sliphead (2). Gently extend the sliphead for a minimum of 4 mm (0.16 inch). Then push back the sliphead.
When the sliphead has the correct tension, at least 22 N (5 lb) of force is required to push in the sliphead from the extended position.

- Install the engine speed/timing sensor.
- Ensure that a tooth on the speed-timing wheel is visible in the mounting hole for the sensor.
- Extend sliphead (2) for 7.8 mm (0.31 inch).
- Coat the threads of the sensor with 4C-5597 Anti-Seize Compound .
Note: The sliphead is designed to contact a tooth of the speed-timing wheel. The maximum allowable gap between the sliphead and the tooth is 0.5 mm (0.02 inch).
- Install the sensor. Tighten the locknut according to the engine's Specifications.
| NOTICE |
|---|
The sliphead must be fully extended when the speed/timing sensor is installed so that the sensor maintains the correct clearance with the speed-timing wheel. If the correct clearance is not maintained, the signal from the sensor will not be generated. Do not install the sensor between the teeth of the speed-timing wheel. Damage to the sensor would result. Before installing the sensor, ensure that a tooth of the wheel is visible in the mounting hole for the sensor. |
