Cracked connecting rods are initially produced as a single unit, then given break lines (sinter rods) or laser notches (steel connecting rods) and split (cracked) into two parts. Both parts are screwed together when the connecting rods are assembled. Due to the point of fracture, they fit together precisely.
Cracked connecting rods are advantageous with regard to strength, costs and production accuracy. Connecting rods and connecting rod caps sit precisely on one another, which allows for optimal force transmission.
