COATS Extended Mobility (EMT) RunFlat Tires - Manual (Page 19)

The Objective of this Section:
To identify the component parts of a valve-type sensor and the proper installation of the sensor
assembly.
Safety Issues Related to this Section:
• Protective eyewear must be worn at all times.
1 Identify the various parts that make up the valve-type
sensor:
Ẅ sensor with metal valve stem; ẅ O-ring; Ẇ
nut, ẇ valve cap.
Inspect the O-ring carefully. If it is damaged, replace it with
a new ring before proceeding.
NOTE: Some sensors are location-specific (i.e.; front left,
right rear, etc.). Always install the correct sensor on the cor-
rect wheel so that the sensor is in the correct position.
2 Inspect the valve mounting hole. Be sure to inspect both
sides of the hole. Make sure it is clean and free of burrs
and nicks that may keep the valve from sealing properly
around the hole. Wipe away any dirt or debris.
3 Verify that air flows freely through the valve. Make sure
the valve core is installed, then apply air pressure to the
valve. Air should flow freely through the valve and sensor,
escaping through the air pressure port in the sensor.
4 Install the sensor by inserting the valve stem through the
mounting hole in the wheel. The sensor should lay back
towards the wheel with the O-ring in full contact with the
inner wheel surface. If a washer is used, place it over the
valve stem and against the outer wheel surface. Screw the
nut down onto the valve stem and finger tighten only. Use a
torque wrench to tighten the nut down to 90-105 inch pounds
(or to the sensor manufacturer’s specifications).
5 When removing a valve-type sensor, use care to avoid
damaging the sensor. Hold on to the sensor to keep it
from falling off the wheel once the nut is removed.
If the sensor is location-specific, make sure it is reinstalled
on the proper wheel.
