Y10010817 Flywheel Assembly is a heavy inertia power storage component matched for JAC YNF40TCIF diesel engine. It stores rotational kinetic energy during power strokes and delivers steady torque through the clutch to transmission, while the integrated ring gear meshes with starter pinion to crank the engine for ignition. This aftermarket replacement flywheel fixes rough idle, unstable power output, ring gear tooth chipping and clutch surface warping caused by thermal deformation, surface scoring and fatigue wear of old flywheels. Stable inertia balance smooths engine rotation and avoids clutch slipping issues for light trucks operating under heavy cargo loads and frequent stop-start delivery cycles.
Product Advantages Made of high-density ductile cast iron with strict dynamic balance treatment to suppress engine vibration. The built-in ring gear adopts quenching process to improve wear resistance against repeated starter engagement. Precision machined clutch friction surface ensures uniform pressure distribution. Every flywheel passes runout inspection and tooth defect screening before shipment, OEM bolt hole layout and positioning bore for direct replacement.
