Place the driven plate, drive plate and retaining plate neatly in this order on surface table.
Set the dial gauge to retaining plate, and read its scale.
NOTE: The value, which is read in the gauge at this time, is zero point.
Scale and record the weight "Z" of a flat board which will be put on retaining plate.
NOTE:
- The value, which is read in the gauge at this time, is zero point.
- Use a flat board weighing less than 52 N (5.3 kgf, 11.7 lb).
Put the flat board on retaining plate.

Using the following formula, read the push/pull gauge and calculate "N".
N = 52 N (5.3 kgf, 11.7 lb) - Z

52 N (5.3 kgf, 11.7 lb) : Load applied to clutch plate

Z: Flat board weight
Press the center of retaining plate by applying a force of "N" using push/pull gauge, and then measure and record the compression amount "A".
NOTE: Measure at four points with a 90° interval and calculate the average.
