To measure
Place a steel ruler between carrier plate and engine
block. Ruler should rest against engine to gearbox
mounting flange and should rest against both sides of
fl ange. Turn crankshaft until one of holes in carrier
plate coincides with steel ruler. Measure B with an
outside caliper equipped for depth measurement.
Measured value B plus thickness of steel ruler should
= 17.2-18.8 mm (0.667-0.740 in). If distance is less
than 17.2 mm = 0.677 in, place a spacer washer (PIN
