RIM DRILLING INSTRUCTIONS FOR WHEEL DRIVE SPEED
SENSOR MAGNETS
On wheels which do not have pre-punched mounting holes, proceed as follows:
RIMS WITH FOUR OR EIGHT HOLE STUD PATTERN:
Choose stud holes that are opposite each other as shown below. Using the center of opposite holes, scribe
two lines on the rim web to divide the circumference into four equal parts. Measure in one inch from the outer
edge of the web on each of the lines drawn. Mark this point as the center. Drill four 1/2" holes for mounting
the magnets.
NOTE:
Distance (D) between each set of drilled holes must be equal within 1/8 [3 mm] to
ensure accuracy of system.
RIMS WITH SIX HOLE STUD PATTERN:
Locate the center of the holes to be drilled by using the rim webbing as a guide. Obtain a small piece of wood
and cut to fit exactly over the web as shown. Measure the length of the piece of wood and mark the center
on one edge. Using the center mark on the piece of wood, mark each of the four webs. Measure in one inch
from the outer edge of the web on each of the lines drawn. Mark this point as center and drill four 1/2" holes
for mounting the magnets.
NOTE:
Distance (D) between each set of drilled holes must be equal within 1/8" [3 mm]
to ensure accuracy of system.
