   1. Using a dial indicator, measure the reverse clutch piston stroke (distance A) and the moving distance (distance B) of the reverse clutch flange at both ends across the diameter while blowing air (392 kPa, 4 kgf/cm², 57 psi) from the oil hole as shown in the illustration, and calculate the average.
      
      

      
      
      
      

      HINT:

      Piston stroke A = 1.05 to 2.15 mm

      Flange moving distance B = 0.72 to 1.08 mm

      Pack clearance = Piston stroke A - Flange moving distance B - 0.06

      Pack Clearance:

      0.5 to 0.8 mm (0.020 to 0.031 in.)
      

      NOTICE:

      Install a selective flange (t = 3.3 mm) when measuring the moving distance. (shaded area in the illustration)

   2. If the pack clearance is outside the standard, select and install a clutch flange that brings the pack clearance within the standard.
      

      HINT:

      There are 11 types of flanges that can be used to adjust the pack clearance. Select the one with the most appropriate thickness.

      Flange thickness:

      No.	Thickness
      0	2.8 mm (0.110 in.)
      1	2.9 mm (0.114 in.)
