    • The piston
    • The piston rings
    • The cylinder bore
    • The bearing surfaces
  2. Stagger the oil control ring end gaps a minimum of 90 degrees.
  3. Stagger the compression ring end gaps a minimum of 25 mm (1.0 in).
  4. Install the J 8037  onto the piston and compress the piston rings. See Special Tools .
