17. Sensor installation/removal procedure

17.1. Maintenance equipment required for TPMS-equipped tires

TPMS-equipped wheels normally use low-section tires with high speed rating or run
flat tires, either self-supporting or auxiliary-supported (PAX System or SR Support
Ring tires with insert). Tire installation/removal procedures are similar to those for
conventional tires, except for auxiliary-supported run flat tires.
To install and remove TPMS-equipped wheel tires, we recommend using the latest
tire changers which are especially suited to install low-section tires or large-size tires
on alloy wheels. It is essential that the tire changer be equipped with plastic pressure
rollers so as to ensure correct pressure during installation without damage to wheel
rim, sensor and tire bead. Shown in the picture is a tire changer suitable for TPMS-
equipped wheels.
For auxiliary-supported run flat tires (PAX System or Support Ring)
equipped with TPM sensors, you will have to use tire
removal/installation equipment approved by the tire manufacturer.
These tires require special accessories and the installation/removal
procedures are different from those used for standard tires.
Follow the installation and removal instructions and procedures
provided by the manufacturers of tire, sensor, vehicle and tire
removal/installation equipment. The information provided herein is
general information applicable to most sensors found in the market.
In addition to the appropriate tire changer, when you change sensors you will also
need suitable sensor replacement kits that include one or more wrenches, O-rings,
valve caps in different colours, valve body and valve insert. Kit contents may vary
depending on sensor type (see paragraph 10.0) and brand.

17.2. Sensor replacement

Installation and removal procedures vary slightly depending on sensor model.
A standard procedure for the valve-and-sensor assembly configuration (design 1,
paragraph 10) may be as follows:
1. loosen the retaining screw so the sensor can move freely.
2. unscrew the nut completely
3. remove valve body from its seat; the sensor must be free to move otherwise the
valve will not come off.
4. unscrew the retaining screw and remove valve body.
