Implement Wheels
1. Prepare and install magnet clips as shown.
2. Place a magnet at the end of each clip (longest side of
magnet should point in the direction of wheel rotation).
See Illustration 5 on previous page. Place a cable tie
(ribbed side toward hub) around the wheel hub and
tighten to secure magnets in place. For large hubs, two
or more cable ties can be joined together.
3. Rigidly mount sensor mounting bracket to the wheel
support assembly. Cut or bend “L” bracket as required
for proper positioning of sensor.
4. Install sensor, adjust to correct spacing (1/4” to 1/2”), and
secure with 3/8” locking nuts. See Illustration 6.
NOTE: Observe magnet polarities (See Previous Page).
Front Tractor Wheel
1. When possible, attach magnet clips as shown for
implement wheel. This may require substituting longer
lug bolts and securing clips with nuts. Magnet clips may
also be secured by drilling and tapping holes for smaller
bolts directly into the hub, or with an adhesive.
2. Mount the speed sensor bracket to a part of the wheel
support 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. See Illustration 7.
3. Insert sensor, adjust spacing and secure with 3/8” locking
nuts.
NOTE: Observe magnet polarities (See Previous Page).
Installation (cont)
Speed Sensor Installation (cont)
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. See page 11 for proper procedure.
2. Cut and bend sensor mounting bracket as needed
and rigidly mount. See Illustration 8.
3. Insert sensor, adjust spacing and secure with 3/8”
locking nuts.
NOTE: Observe magnet polarities (See Previous Page).
CAUTION: Make sure valve stem cannot make contact with
sensor or bracket.
