English – Single Tire AirBAT Sensor Installation
WARNING! Always use appropriate personal protective equipment (PPE)
during the installation and maintenance of the sensors and or related systems
on a vehicle. If you have questions regarding which PPE are appropriate, please
consult
osha 3151-12r 2003 to determine appropriate equipment.
1. Choose the correct bracket for the application. Brackets are available for
drive axles and various trailer hub configurations. Figure 1 shows a hub cap
flange mounted bracket.
2. Attach the AirBAT to the bracket. The AirBAT has an anti-rotation pin on the
back of the manifold that must fit into the small hole in the bracket. Use
the washer and locking nut supplied with the AirBAT.
CAUTION: USING
HAND TOOLS ONLY, TORQUE THE NUT TO 12 ft-lb. Over-
tightening may break off the mounting stud.
See Figure 2.
3. Make a note of the unique serial number printed on the AirBAT cover. Also
note the position on the truck where the AirBAT is being installed (Left-Rear,
Right-Rear, etc.) along with the vehicle ID. This information may be entered
into WebBAT or used for reference at a later time.
4. Hold the bracket (with AirBAT attached) near the hub and visually select a
pair of mounting studs or bolts on the hub so that the AirBAT hose will not
be stretched or be too loose, as shown in
Figure 3. Remove the two bolts
and attach the bracket, using the same bolts. Typical hub cap bolts are
5/16 –18 and are tightened 12–16 ft-lb. of torque.
5. Figure 4 shows the AirBAT attached to a drive axle cover plate. The same
procedure as detailed in step 4 is to be used. Typical drive axle cover plate
nuts are torqued to 250 ft-lb. of torque.
6. Remove any valve stem caps from the wheels. Be sure the threads on the
valve stem are clean and usable with no dings or dents on the sealing edge
of the valve stem. Restore/replace if needed. Connect the AirBAT hose to
the appropriate valve stem and tighten the knurled valve stem fitting to
approximately ½ turn past finger tight. Hand tighten manifold hose fitting
until it is secure and will tighten no further. Use a leak detection method
such as soap and water or a commercial bubble solution to ensure no air
leaks are present.
7. Check the tire pressure with the HandBAT reader or a conventional
tire gauge. The tire may be filled using the fill port on the AirBAT hose
fitting. The HandBAT reading should confirm the unit’s serial number
recorded in step 3.
