    84 N (8.6 kgf, 18.9 lb) : Load applied to clutch plate

    Z: Flat board weight

  12. Press the center of retaining plate by applying a force of "N" or more 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.
