FLOORMAT 1185110 - Caterpillar

The plastic sliphead must be fully extended when the speed/timing sensor is installed so that the sensor maintains the correct clearance with the timing ring. If the correct clearance is not maintained, the signal from the sensor will not be generated.Do not install the sensor's plastic sliphead between the teeth of the timing ring. Damage to the plasic sliphead will result. Before installing the sensor, ensure that a tooth of the ring is visible in the mounting hole for the sensor.
Use the following steps to install the speed/timing sensor:
Ensure that a tooth on the timing ring is visible in the mounting hole for the sensor.
Fully extend the sliphead. Note: The plastic sliphead is designed to contact the tooth of the timing ring during installation. As the timing ring begins to turn, the radial runout of the timing ring will push the plastic sliphead into the sensor body slightly. This provides the plastic sliphead's air gap with a self-adjusting function. The maximum allowable clearance between the sliphead and a tooth on the timing ring is 0.5 mm (0.02 inch).
Coat the threads of the sensor with 4C-5597 Anti-Seize Compound.
Install the sensor. Tighten the sensor to 40 5 N m (30 4 lb ft). Proceed to Test Step 3.
Not OK - The plastic sliphead is damaged and/or the tension of the sliphead is insufficient.Repair: Install a new sensor. Calibrate the sensor. Refer to Troubleshooting, "Timing - Calibrate".If the condition is not resolved, proceed to Test Step 3.Test Step 3. Check for Active Diagnostic Codes for the 12 Volt Sensor Supply
Connect Cat ET to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
Switch the 35 amp circuit breaker ON. Set the engine control to the STOP mode.
Use the "Active Diagnostic" screen on Cat ET. Look for the following codes:
145-3 12 Volt DC Power Supply : Voltage Above Normal
145-4 12 Volt DC Power Supply : Voltage Below NormalExpected Result:None of the above codes are active.Results:
No active codes - None of the above codes are active. However, at least one of the codes is logged.Repair: Clear the logged codes.Proceed to Test Step 4.
Active code - One of the above codes is active. Proceed to Test Step 5.Test Step 4. Use Cat ET to Check the Engine RPM
Use the "Status - Group 1" screen in order to observe "Engine Speed". Observe the "Engine Speed" parameter on the screen and set the engine control to the START mode. Crank the engine.
Continue to observe the screen and allow the engine rpm to stabilize at the normal cranking speed.
Set the engine control to the STOP mode. Expected Result:Before the engine is cranked, the engine speed is "0". The engine speed increases until the speed stabilizes at the normal cranking speed. When the engine is stopped, the speed decreases back to "0". A diagnostic code for the speed/timing sensor is not active.Results:
OK - The engine started and the engine ran properly. A diagnostic code for the speed/timing sensor was not activated. The speed/timing sensor is
