pull gauge, and calculate N.
N = 100 N (10.2 kgf, 22.5 lbf) – Z
N: Value indicated on push/pull gauge
100 N (10.2 kgf, 22.5 lbf): Load applied to clutch
plate
Z: Flat board weight
(6) Press the center of retaining plate by apply-
ing a force of N using push/pull gauge, and then
measure and record the height "A". Measure at
three locations or more spaced by equal dis-
tances and take the average value.
NOTE:
If measuring in three locations, measure every
120°. If measuring in four locations, measure every
90°.
