Disassembly

1. Remove the piston from the engine block (see page 7-14).

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.

3. Remove both snap rings. Start at the cutout in the


3. Remove both snap rings. Start at the cutout in the piston pin bore. Remove the snap rings carefully so they do not go flying or get lost. Wear eye protection.

4. Heat the piston and the connecting rod assembly to


4. Heat the piston and the connecting rod assembly to about 158 Р’В°F (70 Р’В°C), then remove the piston pin.
