  16. Obtain the thickness of washer using the values measured from step 7 to step 15.

    Calculation formula:

    T mm = (B - A) - (C - D) - (0.0 - 0.20)

    [T in = (B - A) - (C - D) - (0.0 - 0.008)]

    T: Washer thickness

    A: Height from the ST end surface to the snap ring of the forward clutch drum

    B: Height from the ST end surface to the thrust bearing

    C: Height from the ST end surface to the flat board with the snap ring placed on

    D: Height from the ST end surface to the washer catch surface of the forward clutch hub 0.0 - 0.20 mm (0.0 - 0.008 in): Clearance

  17. Select the washer to meet the value "T" obtained from step 16.
  18. Install the dish plate, drive plate, driven plate and retaining plate.
  19. Install the planetary carrier.
  20. Install the snap ring.
  21. Hold the forward clutch drum on a vise, and set the magnet stand and dial gauge (spindle type).
