Pistons and piston pins wear together. Mixing pistons and piston pins can lead to problems with the rotation of the piston pin.Mark the piston and piston pin with the cylinder number in order to retain the orientation of the piston and piston pin for reassembly. Use the front of the engine for the reference orientation of the piston and piston pin. Refer to Special Instruction, SEBF8049, "Piston Visual Inspection" for additional information.Note: Do not mix the pistons and piston pins from different cylinders. Ensure that the pistons and piston pins are oriented properly with reference to the front of the engine.
