Collection: Crank Shafts
The crank shaft is a vital component of a car's engine, responsible for converting the reciprocating motion of the pistons into rotational motion. It is a sturdy, cylindrical shaft that connects to the pistons via the connecting rods. The crank shaft's main function is to transfer the up-and-down motion of the pistons into a rotational motion that drives the vehicle's wheels. It is typically made of a strong alloy steel to withstand the high stresses & forces generated during engine operation. The crank shaft undergoes precise machining & balancing to ensure smooth operation & minimize vibration. It features a series of counterweights strategically placed along its length to balance the forces exerted by the moving pistons. The crank shaft is supported by bearings within the engine block, which allow it to rotate freely. Regular maintenance & oil changes are crucial to keep the crank shaft properly lubricated & minimize wear. A damaged or worn crank shaft can lead to engine performance issues, excessive vibration, & even engine failure. In such cases, it may be necessary to replace the crank shaft with a new or remanufactured unit to restore the engine's functionality.
