Sensor Installation–Strap-Type

1. Find the correct sensor for the specific
wheel location and identify the correct location
on the wheel.

2. Lay the strap around the drop center and
overlap the ends. Trim the strap so that it over-
laps itself by 2 to 3 inches.

3. Slide the counterweight onto the strap.

4. Slide the sensor onto the strap with the label
side facing upwards.

5. Feed the strap end into the tensioner and
begin tightening the strap. As the strap tight-
ens, be sure to adjust the positioning of the
counterweight and sensor–the counterweight
should be directly beneath the valve stem and
the sensor should be directly across from the
counterweight 180° around the wheel, the ten-
sioner should be 2 to 3 inches away from the
sensor.

6. Tighten the strap securely, and torque to 30
inch/pounds. The strap should be level and the
weight and sensor in proper position before
proceeding.

7. Trim the excess strap to leave no more than
1 inch.

Mounting–Strap-Type Sensor

1. Determine the correct length rubber valve
stem. Clean the valve hole. Lubricate the valve
thoroughly to insure a good, leak-free installation.

2. Install the rubber valve stem. Use a shop
towel to prevent damage to the wheel.

3. Clean and polish the wheel. Check for any
burrs or damage to the wheel that might dam-
age the tire during the mounting process.
Always clamp the wheel externally.

4. Lubricate the entire surface of the wheel lib-
erally with a slow-drying lubricant.

5. Lubricate the lower tire bead.

6. Rotate the tabletop so that the valve stem is
at the 12 o’clock position and the sensor is at
the 6 o’clock position. Lubricate and position
the duckhead so that it is against the wheel.

7. Hold the tire down with the lower bead in the
drop center and rotate the wheel slowly. The
lower bead should be eased over the wheel
slowly and carefully, giving the sidewall time to
relax. Once the lower bead is mounted, grasp
the tire and carefully guide the lower bead
over the sensor.

8. Before beginning to mount the upper bead,
rotate the tabletop until the valve stem is once
again in the 12 o’clock position and the sensor
is at 6 o’clock. Apply lubricant to both the edge
of the tire bead and the underside of the bead.

9. Position the upper bead over the duckhead.
Put the tip of the lift tool under the wheel rim
flange and push the bar down to hold the upper
bead below the wheel and duckhead. Use a
shop towel on the lift tool to avoid damaging
the wheel.

10. Rotate the wheel a short distance–only 3 to
4 inches–and stop. Continue to hold the bead in
the drop center with the lift bar, or place a drop
center tool on the wheel.

11. Continue rotating the wheel short distances
until the upper bead is fully mounted removing
the lift bar or drop center tool at the 10 o’clock
position.
