manufacturer's instructions. If the ridge is not removed, it may damage the pistons as they are pushed out.
14. Use the wooden handle of a hammer (A) to drive out the pistons (B).
15. Reinstall the lower block and bearings on the engine in the proper order.
16. Reinstall the connecting rod bearings and caps after removing each piston/connecting rod assembly.
17. To avoid mix up on reassembly, mark each piston/connecting rod assembly with its cylinder number.
NOTE: The existing number on the connecting rod does not indicate its position in the engine, it indicates the rod bore size.
