  1. Install the disc set to DT 46477  (1). See Special Tools .
  2. Place the dial gage sensor on DT 46480  . See Special Tools .
  3. Feed the compressed air to clutch E through the control valves.
  4. Set the dial gage to zero.
  5. Lift the measurement ring B by hand until it touches the cup and reads the measurement value.
  6. Repeat the measurement twice with the disc set turned by 120 degrees.
  7. The average measurement values M4, M5, M6. Measurement value is MB.
    • The minimum installation space EB is equal to the height of the ring RB plus measurement value MB.

      Specification:  The specification value for the height of the ring RB is 11.99 mm (0.472 in).

    • CALCULATION

      MB = (M4 + M5 + M6)/3

      EB = RB + MB

    • EXAMPLE

      M4 = 2.36 mm (0.093 in)

      M5 = 2.40 mm (0.094 in)

      M6 = 2.38 mm (0.094 in)

      So, MB = (2.36 + 2.40 + 2.38)/3 = 2.38 mm [(0.093 + 0.094 + 0.094)/3 = 0.094 in]

      EB = 11.99 + 2.38 = 14.37 mm (0.472 + 0.094 = 0.556 in)
