EXCAVATOR ENGINE CRANKSHAFT SERIES FOR D4D VOLV O

Our excavator engine crankshaft is forged from high‑strength alloy steel. Multiple heat‑treatment processes including quenching‑tempering and journal surface hardening greatly improve wear resistance and anti‑fatigue capacity, coping with heavy‑duty impact loads in harsh construction sites.
Precision CNC machining and journal grinding, together with strict dynamic balance testing, guarantee low vibration and stable operation. Fully compliant with OEM dimensions for direct installation without secondary modification.
Each crankshaft goes through strict dimension, hardness and flaw detection before delivery. Effectively prevent fracture and deformation, lower engine breakdown risks, extend engine service life. Reliable replacement part for excavator engine overhaul.
