FORWARD CLUTCH INSPECTION


  1. INSPECT PISTON STROKE OF FORWARD CLUTCH


    1. A003BZZE01

      Using SST and a dial indicator, measure the forward clutch piston stroke while applying and releasing compressed air (392 to 785 kPa, 4.0 to 8.0 kgf/cm2, 57 to 114 psi).

      SST
      09350-30020   ( 09350-06120 )
      Piston stroke
      0.6 to 1.0 mm (0.023 to 0.039 in.)

      If the piston stroke is outside the standard, inspect the discs.

  2. INSPECT FORWARD MULTIPLE DISC CLUTCH CLUTCH DISC


    1. A003BGRE01

      Check to see if the sliding surfaces of the disc, plate and flange are worn or burnt. If necessary, replace them.

      Tech Tips

      If the lining of the disc is peeling off or discolored, or even if a part of the printed numbers is defaced, replace all discs.

  3. INSPECT FRONT CLUTCH PISTON SUB-ASSEMBLY


    1. A003EID

      Check that the check ball is free by shaking the piston.

    2. Check that the valve does not have leaks by applying low-pressure compressed air.

  4. INSPECT INPUT SHAFT SUB-ASSEMBLY


    1. A003HFS

      Using a dial indicator, measure the inside diameter of the forward clutch drum bushing.

      Maximum inside diameter
      24.08 mm (0.948 in.)

      If the inside diameter is greater than the maximum, replace the input shaft sub-assembly.
