The connecting rod and the connecting rod cap should have an etched Number (X) on the side. The number on the connecting rod and the connecting rod cap must match. Ensure that connecting rod (3) and connecting rod cap (2) are marked for the correct location. If necessary, make a temporary mark on the connecting rod and the connecting rod cap in order to identify the cylinder number. Note: Do not stamp the connecting rod assembly. Stamping or punching the connecting rod assembly could cause the connecting rod to fracture.
Remove bolts (1) and connecting rod cap (2) from connecting rod (3).
Carefully push piston (4) and the connecting rod out of the cylinder bore. Lift piston (4) out of the top of the cylinder block. Note: Do not push on the fracture split surfaces of the connecting rod as damage may result.
Repeat Step 1 through Step 5 for the remaining pistons and connecting rods. Note: Fracture split connecting rods should not be left without the connecting rod caps installed. Temporarily install connecting rod cap (2) and bolts (1) to connecting rod (3) when the assembly is out of the engine. Ensure that the etched number on connecting rod cap matches the etched number on connecting rod . Ensure the correct orientation of the connecting rod cap . The locating tab for the upper bearing shell and the lower bearing shell should be on the same side. Tighten bolts (1) to a torque of 20 N m (177 lb in).
