  7. Before measuring clearance "A", place same thickness shims on both sides to prevent the plate from tilting.
  8. When the clearance "A" exceeds the limit for use, select the transfer clutch plate set and pressure plate, and adjust the clearance "A" within the initial specified value.

    Initial standard:

    0.7 - 1.1 mm (0.028 - 0.043 in)

    Limit thickness:

    1.45 mm (0.057 in)
