INSTALLATION
RIM DRILLING FOR SIX HOLE WHEEL STUD PATTERNS - OPTIONAL
This section is required only on wheels that do not have pre-punched mounting holes. If your machine has the
pre-punched mounting holes, proceed to the Mounting the Wheel Drive Speed Sensor section.
FIGURE 4. Six Hole Stud Pattern
1. Cut a piece of wood so that it is an exact fit from the top edge of the rim to the bottom edge of the rim.
2. Measure the length of the cut wood block and mark the center.
3. Using the wood block as a guide, draw two lines across the wheel, dividing the wheel into four equal parts.
4. Measure in one inch from the rim on each end of the lines and mark the wheel at each point.
5. Drill a 1/2” hold on each of the four marks.
NOTE: The distance between each set of drilled holes must be equal within 1/8” [3 mm] to ensure system
accuracy.
MOUNTING THE WHEEL DRIVE SPEED SENSOR
1. Select a non-driven wheel (a front wheel if the machine is rear-wheel drive, or a back wheel if the machine is
front-wheel drive) on which to mount the sensors.
FIGURE 5. Wheel Magnet Mounting
2. Mount the four magnets in the pre-punched or drilled mounting holes on the inside of the wheel so that the
red magnets are on opposite sides of the wheel.
3. Tighten the nuts on the wheel magnets to ensure they are installed securely.
