    5. Install the remaining snap ring (F).

    NOTE:  Turn the snap rings in the ring grooves until the end gaps are positioned at the bottom of the piston.

    6. Reassemble the other pistons the same way.

  2. Piston Ring - Install

    Standard (New):  0.045-0.070 mm (0.002 in) 
    Service Limit:  0.13 mm (0.005 in) 
    Second Ring (TEIKOKU) 
    Standard (New):  0.035-0.060 mm (0.002 in)

    1. Remove the connecting rod caps. Check that the bearing is securely in place.

    2. Apply new engine oil to the piston, inside of the ring compressor, and the cylinder bore, then attach the ring compressor to the piston/connecting rod assembly.

    3. Position the piston/connecting rod assembly with the arrow (A) facing the cam chain side of the engine block.

    4. Position the piston/connecting rod assembly in the cylinder, and tap it in using the wooden handle of a hammer (A). Maintain downward force on the ring compressor (B) to prevent the rings from expanding before entering the cylinder bore.

    5. Stop after the ring compressor pops free, and check the connecting rod-to-rod journal alignment before pushing the piston into place.

  4. Oil Jet - Install 
  5. Crankshaft - Install
