Product Description
X10010091 Crankshaft Sprocket is the core timing drive gear installed on the front end of crankshaft for JAC YND20TCIF diesel engine. It transfers crankshaft rotation power through timing chain to camshaft sprocket, ensuring accurate valve opening and closing timing matched with piston movement. This aftermarket replacement sprocket fixes timing jump, abnormal chain rattling and power drop caused by tooth surface wear, tooth chipping and keyway deformation of old sprockets. Precise timing control prevents valve and piston collision accidents, securing reliable running for light trucks undertaking urban distribution and frequent load-changing logistics tasks.
Product Advantages Made of high-hardness alloy steel with surface quenching treatment, offering strong wear resistance and impact resistance. Accurate tooth profile machining ensures smooth meshing with timing chain and reduces noise. Standard keyway and mounting hole positions align perfectly with crankshaft nose. Each sprocket passes tooth profile inspection and dimensional tolerance test before shipment, OEM specification for direct replacement during timing system overhaul.
