NOTICE:

1. If the linings of the discs are peeled off or discolored, or even a part of the printed numbers is damaged, replace all discs.
   

1. Before assembling new discs, soak them in ATF for at least 15 minutes.
   

Inspect the pack clearance of the reverse clutch hub sub-assembly.

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 a 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 = 1.62 to 2.68 mm (0.0638 to 0.1055 in.)

   Flange moving distance B = 1.22 to 1.67 mm (0.0480 to 0.0657 in.)

   Pack clearance = Piston stroke A - Flange moving distance B - 0.02 mm (0.0008 in.)

   Pack Clearance:

   0.4 to 0.7 mm (0.016 to 0.028 in.)
   

   NOTICE:

   Install a selective flange {t = 2.8 mm (0.110 in.)} when measuring the moving distance (shaded area in the illustration).

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

   HINT:

   There are 12 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	2.4 mm (0.094 in.)
   1	2.5 mm (0.098 in.)
   2	2.6 mm (0.102 in.)
   3	2.7 mm (0.106 in.)
   4	2.8 mm (0.110 in.)
   5	2.9 mm (0.114 in.)
   6	3.0 mm (0.118 in.)
   7	3.1 mm (0.122 in.)
   8	3.2 mm (0.126 in.)
   9	3.3 mm (0.130 in.)
   A	3.4 mm (0.134 in.)
   B	3.5 mm (0.138 in.)
