all reservoirs before beginning ANY work on the vehicle. If the vehicle is equipped with an AD-IS™air dryer system or a dryer reservoir module, be sure to drain the purge reservoir.

5.Following the vehicle manufacturer’s recommended procedures, deactivate the electrical system in a manner that safely removes all electrical power from the vehicle.

6.Never exceed manufacturer’s recommended pressures.

7.Never connect or disconnect a hose or line containing pressure; it may whip. Never remove a component or plug unless you are certain all system pressure has been depleted.

8.Use only genuine Bendix® replacement parts, components and kits. Replacement hardware, tubing, hose, fittings, etc. must be of equivalent size, type and strength as original equipment and be designed specifically for such applications and systems.

9.Components with stripped threads or damaged parts should be replaced rather than repaired. Do not attempt repairs requiring machining or welding unless specifically stated and approved by the vehicle and component manufacturer.

10.Prior to returning the vehicle to service, make certain all components and systems are restored to their proper operating condition.

REMOVAL

1.Unplug the cable assembly connector from its lead. Lift the lock tab and pull on the connector until it disengages.

2.Gently pry the sensor and bushing from the mounting block.

INSPECTION

Look for any visible damage to the sensor, cable assembly, connector, mounting block, and foundation brake. Repair or replace any damaged components. Make sure the block is securely attached to the axle housing.

SENSOR INSTALLATION

1.For increased corrosion protection we recommend that a high-temperature rated silicon- or lithium-based grease be applied to the interior of the mounting block, the sensor, and to a new clamping sleeve.

2.Gently push (DO NOT STRIKE) the sensor into the mounting block hole until it bottoms out on the face of the tone ring. Secure the cable lead wire to the knuckle/ axle housing 3-6 inches from the sensor.
