For incorporated sensors (design 2, paragraph 10), simply perform steps 2 and 3 of
the above procedure.
A standard procedure for the valve-and-sensor assembly configuration may be as
follows:
1. Obtain a complete replacement kit including TPM sensor and all other parts
(valve body, retaining screw, nut, valve cap).
2. Insert valve and O-ring into valve seat. Install the nut to retain valve to wheel
rim, but do not tighten yet. The nuts have a small plastic grommet inside that
must be sheared upon final tightening. When the nut becomes hard to turn,
stop.
3. Install sensor onto valve body and secure it with the retaining screw. These
sensors can be installed at varying angles to accommodate different rim
configurations. Before final tightening, look up the sensor manufacturer's
instructions to make sure that torque is correct, that sensor is in the correct
position (i.e. touching the wheel rim or not) and that the external portion of the
sensor is below bead seat. If these requirements are not met, the sensor might
damage during tire installation.
4. Tighten the valve nut firmly (the grommet inside the nut must break) to the
torque specified by the sensor manufacturer.
5. Install the tire.
Standard procedure for incorporated sensor (design 2)
1. Make sure the O-ring is in place on the valve body and insert it into the rim
hole.
2. Fit the nut to secure the sensor into place so that is parallel with the rim and
tighten to the torque specified by the TPMS manufacturer.
3. Install the tire.
For valve-and-sensor assemblies, replace valve body, screw and nut, O-ring, valve
insert and valve cap each time tire is replaced or serviced. For incorporated sensors,
replace valve insert, nut, O-ring and valve cap. Appropriate replacement kits are
available from TPM sensor manufacturers.
