Transfer Clutch: Installation

  1. Install the transfer clutch plate set to the center differential carrier.

    3. Using the following calculation, calculate an appropriate thickness "T" of the driven plate No. 3.
      NOTE: Adjust using 1 piece.

      T = (H1 - 15 mm (0.591 in)) - (H2 - 50 mm (1.970 in)) - 0.2 - 0.6 mm (0.008 - 0.024 in)

      T Thickness of driven plate No. 3 (mm (in))
      H1 Measured value (mm (in)) of step (1)
      H2 Measured value (mm (in)) of step (2)
      15 mm (0.591 in) Thickness of ST (GAUGE)
      50 mm (1.970 in) Thickness of ST (PISTON GUIDE)
      0.2 - 0.6 mm (0.008 - 0.024 in) Clearance specification
