What is a connecting rod?

The connecting rods transfer the rotating force of the crankpin to an oscillating force on the wrist pin. Connecting rods are split perpendicular to their centerlines at the crankpin end for assembly of the rod onto the crankshaft. The cap and rod are aligned with close-tolerance bushing or body-bound bolts. The rods may be rifle drilled or they may have cast passages for transferring oil from the wrist pin to the crank pin. A connecting rod with a tension load is made of forged steel, cast steel, or fabricated steel. Rods with a compression loading are cast nodular steel or aluminum alloy.
