Crankshaft
Detroit Diesel

The crankshaft serves as the core rotational component within the engine, translating reciprocating piston motion into rotary movement to power the vehicle. Its robust steel construction ensures durability under high-stress conditions typical of heavy-duty applications, providing the strength necessary to withstand cyclic loads over extended service periods. With a precise length of over 1200 mm, this shaft is engineered for optimal balance and smooth operation, reducing vibrations and enhancing overall engine performance. The design features carefully machined journals and bearing surfaces that facilitate seamless rotation and efficient power transfer. Maintaining proper alignment and integrity of the crankshaft is vital for engine longevity, as it directly influences piston motion and timing. This part plays a critical role in engine efficiency, fuel economy, and emission control, making it indispensable for heavy-duty trucking operations.
