  1. Use a J 7872  in order to measure the forward clutch piston stroke before disassembly. See Special Tools .
    1. Temporarily install the direct clutch assembly onto the fluid pump (2) and the forward clutch assembly into the direct clutch assembly.
    2. Place the J 7872  plunger on the forward clutch piston and apply 392-785 kPa (57-114 psi) of compressed air into the forward clutch apply passage on the fluid pump. See Special Tools .
    3. Standard forward clutch piston stroke should fall within 1.420-1.810 mm (0.0559-0.0713 in).

  2. If a correct reading cannot be obtained, remove the forward clutch assembly from the direct clutch assembly. Apply 392-785 kPa (57-114 psi) of compressed air into the forward clutch assembly passage (1) on the input shaft (2) and observe the J 7872  . See Special Tools .
  3. If the forward clutch piston stroke is greater or less than specified, inspect all direct clutch components for excessive wear.

  9. Remove the forward clutch piston (1) from the forward clutch drum (2) by applying low pressure compressed air into the forward clutch apply passage on the input shaft.
  10. Remove the two forward clutch piston seals from the forward clutch piston.
  11. Clean all the forward clutch components and dry thoroughly.
  12. Inspect the forward clutch discs for excessive wear or damage. Replace the discs as necessary.
  13. Inspect the forward piston for cracks or porosity. Replace the piston as necessary.
    14. Fig 8: Checking Working & Release Sides Of Forward Clutch Piston With Compressed Air

  14. Inspect the forward clutch piston check ball (1) operations by applying compressed air into the working and release sides of the forward clutch piston (2). There must be no air leakage on the working side and air must pass freely through the release side. If these conditions do not exist, replace the forward clutch piston.
  15. Inspect the forward clutch piston return spring for distortion or weakness. Replace the spring as necessary.
