l Mark a reference position on the coupling housing close to the shaft and in line with a
convenient external reference or flange bolt. Likewise, mark a reference point on the
shaft.
l Measure the circumference of the shaft and divide by eight.
l Use this distance to make seven more evenly-spaced marks on the shaft beginning at
your chosen start point. Number the points counterclockwise as seen from sensor to
laser, beginning with 0 first, followed by 1:30, 3:00,4:30, 6:00, 7:30, 9:00 and 10:30.
For circular housings, measure the circumference of the coupling housing and divide by eight.
Use this distance to make eight evenly-spaced marks on the housing beginning at your chosen
start point. Number the points clockwise looking down onto the shaft with 0 as the first, fol-
lowed by 1:30, 3:00,4:30, 6:00, 7:30, 9:00 and 10:30.
