Product Description
X10012972 Crankshaft Sprocket is the critical timing drive gear mounted on the crankshaft front end of JAC YND25TCIF diesel engine. It transmits rotary power via timing chain to the camshaft sprocket, maintaining synchronized valve actuation and piston motion for correct engine timing. This aftermarket replacement sprocket resolves timing skip, rattling chain noise and power reduction triggered by tooth surface abrasion, broken gear teeth and deformed key slots on original worn sprockets. Accurate timing coordination avoids valve-piston contact damage and guarantees dependable operation for light trucks in urban delivery and variable-load freight scenarios.
Product Advantages Constructed from high-hardness alloy steel with surface quenching treatment for superior wear and impact resistance. Precision machined tooth profile enables smooth meshing with timing chain and minimizes operating noise. Standard keyway and mounting holes match crankshaft nose perfectly. Every sprocket is inspected for tooth profile accuracy and dimensional tolerance before delivery, OEM standard for straightforward replacement during timing system overhaul.
