    3. Reinstall the connecting rod bearings and caps after removing each piston/connecting rod assembly.

    4. Mark each piston/connecting rod assembly with its cylinder number to make sure they are reused in original order.

    		 1. Using a ring expander (A), remove the old piston rings (B).

    2. Clean all the ring grooves thoroughly with a squared-off broken ring or a ring groove cleaner with a blade to fit the piston grooves. File down the blade, if necessary. The top and second ring grooves are 1.0 mm (0.039 in) wide and the oil ring groove is 2.0 mm (0.079 in) wide. Do not use a wire brush to clean the ring grooves or cut the ring grooves deeper with the cleaning tool.

    NOTE:  If the piston is to be separated from the connecting rod, do not install new rings yet.
  19. Piston Pin - Remove

    		 2. Remove the snap rings (A) from both sides of each piston. 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.
