  1. FIX FORWARD CLUTCH ASSEMBLY


    1. A003E72

      Place wooden blocks or similar objects to prevent forward clutch shaft from touching the work stand, and place the O/D support on them.

    2. Place the forward clutch onto the O/D support.

  2. 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.

  3. REMOVE DISC


    1. A003GZK

      Using a screwdriver, remove the snap ring from the forward clutch drum.

    2. Remove the flange, the 5 plates and the 5 discs.

    3. A003FGR

      Remove the cushion plate.

  4. 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.

  5. REMOVE FORWARD CLUTCH RETURN SPRING SUB-ASSEMBLY


    1. A003BXBE01

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

      SST
      09350-30020   ( 09350-07040 )

    2. Using SST, remove the snap ring.

      SST
      09350-30020   ( 09350-07070 )
    3. A003FZU

      Remove the piston return spring.

  6. REMOVE FRONT CLUTCH PISTON SUB-ASSEMBLY


    1. A003EBX

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

    2. Hold the forward clutch piston by hand, and apply compressed air (196 kPa, 2.0 kgf/cm2, 28.5 psi) to the O/D support to remove the forward clutch piston.

    3. Remove the forward clutch piston.

    4. A003DNA

      Remove the O-ring from the forward clutch drum.

  7. REMOVE FORWARD CLUTCH PISTON O-RING


    1. A003ATYE01

      Using a small screwdriver, remove the 2 O-rings.

  8. 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.

  9. REMOVE INPUT SHAFT OIL SEAL RING


    1. A003F2H

      Remove the 3 oil seal rings from the forward clutch drum groove.

  10. REMOVE INPUT SHAFT SUB-ASSEMBLY
