Illustration 1 g00595557Note: The word "FRONT" is stamped on the crown of one piece pistons (1). Install the piston with the word "FRONT" toward the front of the engine. The front of the engine is opposite the flywheel end. The part number on the connecting rod should be facing the rear of the engine. The rear of the engine is the flywheel end. Lubricate the entire piston prior to assembly into the cylinder block. Use clean engine oil.
