Product Description
Heavy‑Duty Forklift Engine Crankshaft
Our forklift crankshaft is one of the most critical core components of the diesel forklift engine. It converts the reciprocating linear motion of pistons into rotational power output. Manufactured in compliance with OEM standards, this crankshaft adopts high‑strength alloy cast iron or forged steel material, with journal surface quenching and strict dynamic balance calibration. It delivers outstanding anti‑fatigue, wear‑resistant and deformation‑resistant performance under heavy‑load continuous working conditions.
Worn, bent or cracked crankshaft will cause serious engine faults, including abnormal knocking noise, severe vibration, oil leakage, unstable power output and even engine locking. Replacing with high‑quality crankshaft can eliminate such hidden dangers, restore normal engine operation and avoid costly secondary damage to connecting rod, piston and cylinder block.
This aftermarket crankshaft has passed dimensional inspection, surface hardness test and dynamic‑balance test before delivery. Widely compatible with Xinchai 490B/495B, Quanchai QC490 series diesel engines, fits 2‑3.5‑ton domestic diesel forklifts for warehouse, port and factory heavy‑duty application.
