The engine crankshaft is a central component of the crankshaft assembly, converting the reciprocating motion of the pistons into rotational motion. Its condition directly affects engine balance, vibration levels, and overall durability.
Manufactured from high-strength steel or cast iron, the crankshaft features main journals, connecting rod journals, counterweights, and internal oil passages. It operates together with connecting rods, pistons, bearings, flywheel, and the lubrication system.
Common wear or damage symptoms include low oil pressure, knocking noise, excessive vibration, journal scoring, or structural deformation. Severe damage may result in engine seizure.
Our catalog includes crankshafts for petrol and diesel engines across various vehicle brands. Genuine factory crankshafts, reconditioned units, and tested used components are available.
Used crankshafts are inspected for runout, journal condition, absence of cracks, overheating signs, and geometry accuracy. Oversize or undersize specifications are indicated when applicable.
Selection is based on VIN number, engine code, cylinder configuration, displacement, and part number. Crankshaft replacement is typically required during major engine rebuilds or after critical mechanical failure.
