    Typical example

  1. Use tool (A) in order to remove the circlips (2) from piston (4).

  2. Remove the piston pin (3) from the piston (4).

    Note: If the piston pin cannot be removed by hand, heat the piston to a temperature of 45 ± 5 °C (113 ± 9 °F). Do not use a oxyacetylene torch to heat the piston. Mark the piston pin for installation.

  3. Check the condition of the following parts: circlips (2), piston pin (3) and piston (4). If these items are worn or damaged, use new parts for replacement. Refer to Specifications, "Pistons and Rings" and Specifications, "Conrods" for more information.

    Typical example

  4. Use tool (B) in order to remove the following items from piston (4): top piston ring (7), intermediate piston ring (6) and oil control piston ring (5).

    Note: Identify the orientation of the piston rings for installation.

  5. Check the condition of the piston rings. If the piston rings are worn or damaged, use new parts for replacement. Refer to Specifications, "Pistons and Rings" for more information.
