Crankshaft reconditioning is a process of repairing a worn-out or damaged crankshaft, which is an essential component of an internal combustion engine.

The process begins with a thorough inspection of the crankshaft to determine the extent of damage, including any cracks, wear, or out-of-roundness. The damaged areas are then machined or ground down, and new bearing surfaces are created to restore the proper tolerances. The repaired crankshaft is rechecked for balance and straightness to ensure optimal performance.

The goal of crankshaft reconditioning is to restore the original function of the crankshaft, along with increasing its durability and lifespan. A well-reconditioned crankshaft will provide better engine performance and longevity, reducing the need for costly engine replacements.
