NOTE: Before reinstalling used rings or installing new rings, the ring clearances must be checked.
  1. Wipe the cylinder bore clean.
  2. Insert the ring in the cylinder bore.
    NOTE: The ring gap measurement must be made with the ring positioned at least 12 mm (0.50 inch.) from bottom of cylinder bore.
  3. Using a piston, to ensure that the ring is squared in the cylinder bore, slide the ring downward into the cylinder.
  4. Using a feeler gauge check the ring end gap. Replace any rings not within specification.
