ELECTRICS 2.27 Procedure to install a sensor The sensor has three pads which are bonded and bolted to the rear axle. NOTES: (1) When bolted to the rear axle the elements of the sensor must not be twisted or stretched. If the elements are twisted or stretched an offset will be applied to the sensor. (2) When bonding sensor to rear axle ensure matting surfaces are free from dirt, grease and any other contamination. A poor bond will affect the performance of the system. Adhesive (154-8875) and activator (154-8876) are required to install the sensor to the rear axle. The procedure to install the sensor is as follows. 1.
Disconnect the connector that attaches the sensor to the intermediate harness. Remove any cable straps that secure the sensor harness. 2. Remove the three bolts that secure the sensor to the rear axle and remove the sensor. 3. Thoroughly clean the surface area on the rear axle where the sensor is to be mounted. All traces of adhesive must be removed. Remove all traces of paint and corrosion. Use a suitable cleaning agent to remove the main debris and degrease the surface. 4. Ensure the area is thoroughly degreased and dry with a suitable clean cloth. 5. Prepare the new sensor for fitting. Remove any protective coating and thoroughly clean the mating surface of the sensor. 6.
Hold the sensor to the axle and check the alignment of the three bolt holes. Loosely install the three bolts and check that the sensor is not pre-stressed by the bolts. 7. Remove the bolts and sensor. 8. Ensure the area is still clean and apply a thin film of activator (154-8876) to the surface area of the axle where the sensor is to be mounted. 9. Apply a thin film of adhesive (154-8875) to the mounting surface of the sensor.
