  1. Remove the piston from the engine block (see CRANKSHAFT AND PISTON REMOVAL  ).
  2. Apply new engine oil to the piston pin snap rings (A) and turn them in the ring grooves until the end gaps are lined up with the cutouts in the piston pin bores (B).
    NOTE: Take care not to damage the ring grooves.
