Implement Wheels
1. Secure magnets mechanically or with epoxy.
2. Rigidly mount sensor mounting bracket to the wheel
assembly. Cut or bend “L” bracket as required for proper
positioning of sensor.
3. Install sensor, adjust to correct spacing (¼” to ½“ or 6 to
13 mm is recommended), and secure with 3/8” locking
nuts.
See Illustration on the right.
Front Tractor Wheel
1. Magnets may also be secured with a cable tie and an
adhesive such as epoxy.
2. Mount the speed sensor bracket to a part of the wheel
assembly that does not change position to the hub when
the wheels are turned. If the “L” bracket provided cannot
be bent and mounted to properly position the sensor,
make a bracket similar to the one shown at right.
3. Install sensor, adjust to correct spacing (¼” to ½“ or 6 to
13 mm is recommended), and secure with 3/8” locking
nuts.
See Illustration below.
Appendix A -
Optional Speed Sensor Mounting Installation
ATV Wheels
Two mounting examples are illustrated.
1. Using one cable tie (ribbed side toward magnets), secure
two magnets to the wheel hub so they are exactly
opposite each other. Alternate the magnets’ polarities.
2. Cut and bend sensor mounting bracket as needed and
rigidly mount.
3. Insert sensor, adjust spacing (¼” to ½” or 6 to 13 mm) and
secure with 3/8” locking nuts.
CAUTION: Make sure valve stem cannot make contact with
sensor or bracket.
