Rotate the crankshaft until the pistons are below the carbon deposits that are found above the ring travel area.
Use a fine fibrous abrasive pad, Part Number 3823258 or equivalent, and solvent to remove the carbon.
Mark each piston according to the cylinder location.
NOTE: On pistons with anodized coatings, do not stamp on the anodized coating or on the outer rim. Do not stamp
on the aluminum piston crown above the piston pin axis.
Rotate the crankshaft to position the rod caps at bottom dead center for removal.
Mark each connecting rod and rod cap according to the cylinder number location.
Some engines are equipped with an external Torxru bit (E-12).
Loosen the connecting rod capscrews.
Do not remove the capscrews from the rods at this time.
Use a rubber hammer to hit the connecting rod capscrews to loosen the caps.
Remove the connecting rod capscrews.
Remove the rod cap.
Remove the lower rod bearing.
Mark the cylinder number and the letter “L” (lower) on the flat surface of the bearing tang.
Push the connecting rod and piston assembly out of the cylinder bore. Care must be taken not to damage the
connecting rod or bearing.
Remove the upper rod bearing.
Mark the cylinder number and the letter “U” (upper) on the flat surface of the bearing tang.
The piston and connecting rod assemblies must be installed in the same cylinder number from which they were removed to provide for proper fit of worn mating surfaces, if parts are reused.
Use a tag to mark the cylinder number from which each piston and rod assembly was removed.
Place the rod and piston assemblies in a container or fixture to protect them from damage.
