Connecting rods are an engine component that transfers motion from the piston to the crankshaft.

And, Are designed to withstand dynamic stresses from combustion and piston movement.

Connecting rods convert the reciprocating motion of the piston into rotary motion of the crankshaft.

The connecting rod creates the link between the piston and crankshaft and thus transmits power. It converts the linear up Connecting rod and down movement of the piston into the circular motion of the crankshaft and is therefore subject to tension, compression, bending and buckling.

So, The connecting rod is mounted on the crank pin of the crankshaft with a plain bearing. Also, The connecting rod bearing cap is bolted to the big end. Finally, In most cases the connecting rod is hollow or provided with an internal cast oil duct to supply the gudgeon pin with lubricant.

  • Connecting rods form the link between the crankshaft and the pistons and transfer the gas and inertial forces to the crankpins on the crankshaft. The connecting rod pushes and pulls the piston into and out of the cylinder.
  • The small connecting rod eye on the piston side serves as a mounting for the piston bolt and is frequently equipped with a bronze connecting rod bearing bush.
  • The connecting rods are mounted with rod bearing shells on the crankshaft pins on the crankshaft. The large connecting rod eye is split to allow mounting on the crankshaft.
  • Connecting rods are forged or cast from steel. Depending on the intended strain, alloyed or hardened and tempered steel may be used.
  • Connecting rods must be replaced if they become fractured or bent.
