Inspect connecting rod (1) and connecting rod cap (3) for the proper identification mark. Connecting rod (1) and connecting rod cap (3) should have an etched number on the side that is toward the right side of the engine. The number should match the cylinder number. The bearing retainer notch should also be on the right side. Mark connecting rod (1) and connecting rod cap (3), if necessary. 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.
