Forward Clutch Cylinder: Disassembly

  1. Inspect the clutch cylinder thrust surfaces, piston bore and clutch plate serrations for scores or burrs. Minor scores or burrs may be removed with crocus cloth. Install a new clutch cylinder if badly scored or damaged.
  2. Check the fluid passage in the clutch cylinder for obstructions. Clean out all of the fluid passages. Inspect the clutch piston for scores and install new, if necessary. Inspect check balls for freedom of movement and correct seating.
  3. Check the clutch release spring for distortion and cracks. Install a new spring (including wave spring) if distorted or cracked.
  4. Inspect the composition clutch plates, steel clutch plates and clutch pressure plate for worn or scored bearing surfaces. Install new parts if deeply scored or burred.
  5. Check the clutch plates for flatness and fit on clutch hub serrations. Discard any plate that does not slide freely on serrations or that is not flat.
  6. Check the clutch hub thrust surfaces for scores and clutch hub splines for wear.
    7. NOTE: The forward clutch hub may remain in the shell during disassembly.
