Crankshaft for Volkswagen TD73

The crankshaft, identified by part number 21022486, functions as the central rotating shaft within the engine assembly. It converts the linear reciprocating motion of the pistons into the rotational torque required to drive the transmission and other mechanical systems. This component is engineered to manage the rotational forces and stresses generated during the combustion cycle, ensuring the transfer of power throughout the engine block.

This part is compatible with Volkswagen TD73 and B7 engine models. It features specific dimensions and balancing configurations designed to meet the operational requirements of these engines. Proper installation and alignment of the crankshaft are necessary to maintain the rotational integrity of the engine assembly.

In internal combustion engines, the crankshaft works in conjunction with connecting rods and main bearings to facilitate the power stroke. It provides the necessary leverage to translate piston energy into output torque while maintaining the timing of the engine cycle through its connection to the flywheel and timing drive system.
