How to handle cracked connecting rods correctly

Cracking doesn't have any disadvantages but it does have one major advantage: it ensures that the connecting rod shank and the bearing cap fit precisely. But what should you watch out for during installation?

Connecting rods form the link between the crankshaft and the pistons and transfer the gas and inertial forces to the crankshaft. For the connecting rod to be mounted on the crankshaft, the large connecting rod eye must be divided.
One form of creating this division is "cracking": Cracked connecting rods are initially made as a single-part component. The large connecting rod eye is then broken in two in a targeted manner. The two parts are
screwed together again during mounting. The cracked fracture surfaces achieve an excellent fit precision between the connecting rod shank and the bearing cap. To prevent a mix-up, the connecting rod shanks and bearing caps that belong together are labelled with an identical pairing number.
