Connecting rod

A connecting rod is a vital part of an engine that connects the piston to the crankshaft. It converts the piston's up-and-down motion into the crankshaft's rotational motion. This helps transmit the force generated by fuel combustion to the crankshaft, turning the engine . The connecting rod also helps balance the engine 's masses, ensuring smooth operation and reducing vibration.

In general, it's advisable to replace the connecting rod as part of an engine overhaul or when signs of wear, damage, or lack of lubrication are detected during inspection or maintenance. It's important to follow the manufacturer's recommendations and perform regular maintenance to maintain the engine 's proper operation.
