Product Description
LJ4A15Q-1005006BA Flywheel Assembly is an inertia energy storage component specially designed for JAC LJ4A15Q gasoline engine. It reserves rotational kinetic energy during power strokes to smooth crankshaft rotation and delivers torque steadily to the clutch and transmission system. The integrated ring gear meshes precisely with the starter drive pinion to crank the engine for ignition startup. This aftermarket replacement flywheel solves rough idle, fluctuating power output, ring gear tooth chipping and friction surface warping caused by thermal stress, scratch damage and long-term fatigue wear of old flywheels. Consistent inertia balance reduces engine shaking and prevents frequent clutch slip faults for light commercial vehicles used in city delivery and stop-and-go traffic scenarios.
Product Advantages Constructed from high-strength ductile cast iron and processed with strict dynamic balance to suppress vibration across full operating speed range. The built-in starter ring gear undergoes surface quenching treatment for outstanding impact and wear resistance. Precision machined clutch friction plane guarantees even clamping force from pressure plate. Each flywheel is inspected for runout, tooth integrity and dimensional tolerance before shipment, OEM bolt hole layout and locating bore for direct replacement.
