Illustration 1 g03405954 Note: Inspect the connecting rod and connecting rod cap for the proper identification mark. The connecting rod and the connecting rod cap should have an etched number on the side. The number should match the cylinder number. Mark the connecting rod and the connecting rod cap, if necessary. Careful handling is required for fractured connecting rods. The connecting rod and the rod cap should be placed on the sides to prevent damage. When possible, the connecting rod and the rod cap should be bolted together to prevent damage.
