Check whether the sliding surfaces of the discs, the plates, and the flange are worn or burnt.
If necessary, replace them.

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.

Inspect the pack clearance of the direct clutch.

1. Using a dial indicator, measure the moving distance (distance A) of the clutch flange at both ends across the diameter while blowing air to the oil hole as shown in the illustration, and calculate the average.
   

   HINT:

   Flange moving distance A = 0.24 to 1.12 mm (0.0094 to 0.0441 in.)

   Pack Clearance:

   0.5 to 0.8 mm (0.020 to 0.031 in.)
   

   NOTICE:
