7.3 TIRE SENSOR INSTALLATION
1. Remove the wheel from the vehicle and then remove the tire.
2. Wrap the strap around the rim in the lowest point of the drop center well and mark it 1"
(2.5 cm) past the worm gear. Cut the strap at the mark. Excess strap must be removed or
it will potentially break-off and damage the tire.
3. Slide on the sensor.
4. With the strap and sensor positioned in the lowest point of
the drop center well, feed the end of the strap into the worm
gear and pull it tight. Orient the sensor so that it is positioned
at the valve with the worm gear 4" (10 cm) away from the
edge of the sensor. The sensor must always be installed at
the valve in order to know its approximate location after the
tire has been mounted.
5. Hand-tighten the strap using a 5/16" (8 mm) hexagon driver
until the sensor can not be moved. CAUTION: Do not over
tighten the strap. Reference torque: 35 in-lbs (4 Nm).
6. Indicate the location of the sensor by applying the supplied rim label to a clean and dry
location on the rim.
