Tire Pressure Sensor: Service and Repair

Removal

1. Remove the tire.

2. Remove the valve nut.





CAUTION:
The valve nut should not be re-used.

Installation

Sensor Fit

CAUTION:
- Handle the sensor with care.
- Avoid lubricant contact if possible.

1. Assemble valve to sensor and turn valve 3 times with the square part of the screw in the slot.





CAUTION:
- The fit should not be tight i.e. it should still be possible to easily adjust valve angle.
- Ensure that the wheel to be fitted is designed for sensor mount. There should normally be a mark to indicate this.
- Ensure that the valve hole and mating face of the wheel are clean.

2. Mount assembly to wheel.

CAUTION:
Ensure sensor feet are against the wheel throughout the remainder of the assembly process.

3. Tighten washer and nut by hand until the valve thread meets the nut built-in calibrated stop.

CAUTION:
Ensure that the grommet remains in contact with the wheel.




4. Using a torque wrench, tighten the nut to 2.95±0.37 lb-ft (4.0±0.5 Nm) It is normal to feel a break as the 1.7 lb-ft (2.3Nm) calibrated stop in the nut snaps and the torque falls.





CAUTION:
- Increase torque smoothly in order to achieve a clean break of the stop.
- Do not exceed allowed torque.
- Do not use electric or pneumatic tools.
