    INSPECT PISTON STROKE OF DIRECT CLUTCH


    1. A01BBQ8

      Place the direct clutch assembly onto the O/D support assembly.

    2. A01BHW9E01

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

      09350-30020 09350-06120
      Piston stroke
      1.37 to 1.60 mm (0.0539 to 0.0630 in.)

      If the piston stroke is less than the limit, parts may have been assembled incorrectly, so check and reassemble again.

      If the piston stroke is outside the standard, select another flange.

      Tip:

      There are 8 different thicknesses for the flange.

      Table 1. Flange thickness:
      No. Thickness No. Thickness
      53 3.3 (0.130) 57 3.7 (0.146)
      54 3.4 (0.134) 58 3.8 (0.150)
      55 3.5 (0.138) 60 4.0 (0.157)
      56 3.6 (0.142) 62 4.2 (0.165)

    INSPECT DIRECT CLUTCH FLANGE


    1. A01BAWOE01

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

      Tip:

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

    REMOVE DIRECT CLUTCH RETURN SPRING SUB-ASSEMBLY


    1. A01BHQ6E01

      Place SST on the spring retainer, and compress the piston return spring with a press.

      09350-30020 09350-07040

    2. Using SST, remove the snap ring.

      09350-30020 09350-07070

    3. Remove the return spring.

    REMOVE DIRECT CLUTCH PISTON SUB-ASSEMBLY


    1. A01BD9V

      Place the direct clutch drum onto the O/D support.

    2. Hold the direct clutch piston, and apply compressed air to the O/D support to remove the direct clutch piston.

    3. Remove the 2 O-rings from the piston.

    INSPECT DIRECT CLUTCH PISTON SUB-ASSEMBLY


    1. A01BE0Z

      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.

    INSPECT DIRECT CLUTCH DRUM SUB-ASSEMBLY


    1. A01BAAA

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

      Maximum inside diameter
      53.99 mm (2.1256 in.)

      If the inside diameter is greater than the maximum, replace the clutch drum.
