  7. Place the dish plate, driven plate, drive plate and retaining plate neatly in this order on surface table.
  8. 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.
  9. Scale and record the weight "Z" of a flat board which will be put on retaining plate.
    NOTE:
    • Use a stiff board which does not bend against load as a flat board to be put on retaining plate.
    • Use a flat board weighing less than 84 N (8.6 kgf, 18.9 lb).
  10. Put the flat board on retaining plate.

  11. Using the following formula, read the push/pull gauge and calculate "N".

    N = 84 N (8.6 kgf, 18.9 lb) - Z

    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.
