  1. Install the disc set to the DT 46477  (1). See Special Tools .
  2. Place the dial gage sensor on DT 46481  . See Special Tools .
  3. Set the dial gage to 0.
  4. Feed the compressed air to clutch E via the control valves.
  5. Read the measurement value.
  6. Repeat the measurement twice with the disc set turned by 120 degrees.
  7. The average measurement values M7, M8, M9. Measurement value is ME.
    • The minimum installation space BE is equal to the ring height RE plus ME minus snap ring play S.

      Specification:  The specification value of the ring height RE is 20.98 mm (0.826 in).

    • CALCULATION

      ME = (M7 + M8 + M9)/3

      EE = RE + ME - S

    • EXAMPLE

      M7 = 2.6 mm (0.102 in)

      M8 = 2.55 mm (0.100 in)

      M9 = 2.54 mm (0.100 in)

      So, ME = (2.6 + 2.55 + 2.54)/3 = 2.56 mm [(0.102 + 0.100 + 0.100)/3 = 0.101 in]

      EE = 20.98 + 2.56 - 0.25 = 23.29 mm (0.826 + 0.101 - 0.010 = 0.917 in)
