Connecting rod for Scania TD 120

The connecting rod, part number 186749, functions as a core component within the Scania TD 120 engine assembly. Its primary role is to connect the piston to the crankshaft, effectively transferring the force generated by combustion within the cylinder. By linking these two components, the rod converts the linear reciprocating motion of the piston into the rotational motion required by the crankshaft to drive the machinery.

This component is compatible with the Scania TD 120 engine. It features a small end that connects to the piston pin and a large end that attaches to the crankshaft journal using bearings. Maintaining the precise structural integrity of this component is necessary for the internal balance and timing of the engine cycle.

In internal combustion engines, connecting rods are subjected to significant compression and tension forces during the power and exhaust strokes. They must accommodate the inertial forces generated by the piston's movement while maintaining alignment between the piston assembly and the crankshaft. Proper installation and lubrication are necessary to ensure the rod functions correctly within the engine block.
