Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Apply clean engine oil on the following items: the piston, the piston rings and the cylinder bore. Note: Careful handling is required for fractured connecting rods. Fractured faces for the connecting rod and connecting rod cap should not be placed on any surface. The connecting rod and the connecting rod cap should be placed on the sides in order to prevent damage. When possible, the connecting rod and the connecting rod cap should be bolted together in order to prevent damage.

With the number one crankshaft throw at the bottom center, install the piston and connecting rod (1) in the engine. Ensure that the proper piston and connecting rod are in the corresponding cylinder with the bearing retainer notch toward the right side of the engine. Note: The word "FRONT" may be stamped on the crown of the pistons in some engines. Ensure that the word "FRONT" is toward the front of the engine when the piston is installed. The etched number on the connecting rod must be on the right side of the engine in the corresponding cylinder.
Line up the piston and connecting rod with the crankshaft. Use a soft hammer and tap the piston into the cylinder bore until Tooling (A) comes off of the piston.
Before the connecting rod comes in contact with the crankshaft, install the upper half of connecting rod bearing (2). Ensure
