Product Description
7004184C91 Crankshaft is the core power conversion component for JAC HFCJND-3.2 diesel engine. Driven by connecting rods, it turns reciprocating piston thrust into rotary torque and delivers power through the flywheel. This aftermarket replacement crankshaft fixes abnormal engine knocking, unstable oil pressure and power drop caused by journal scuffing, bending deformation, fatigue cracks and damaged thread holes on worn original crankshafts. Reliable power transfer keeps stable engine running and prevents destructive engine failure for light trucks working on heavy-load delivery and frequent stop-start logistics routes.
Product Advantages Adopts high-strength forged steel with journal surface hardening treatment for superior wear resistance and anti-fatigue performance. Precision grinding on main journals and crank pins ensures proper running clearance and stable lubricating oil film. Strict dynamic balance processing reduces vibration across full speed range. Every crankshaft passes straightness detection, magnetic particle crack inspection and dimensional tolerance check before shipment, OEM dimension for direct fit during engine overhaul.
