Drive Sprocket (Premium) JCB JS115 / JS130 - GMOVE
High-class drive sprocket by GMOVE, dedicated to JCB JS series tracked excavators. This Premium version product is made of high-grade cast steel, subjected to a precise induction hardening process. This treatment ensures extreme abrasion resistance for the teeth during interaction with the track chain, guaranteeing long and trouble-free operation of the undercarriage in difficult terrain conditions (sand, mud, rubble).
Product Features:
- Induction Hardening: The sprocket teeth feature a deep hardening zone, which prevents premature wear ("sharpening") and cracking under high torque loads.
- Precise CNC Machining: The mounting holes and the contact surface with the final drive hub are perfectly matched, eliminating play and the risk of shearing the mounting bolts.
- Massive Construction: A weight of approximately 55 kg testifies to the solidity of the casting and lack of material savings, which is crucial for drive stability.

Technical Tip: Before purchasing, absolutely count the number of mounting holes on your machine's hub. In JS130 models, there are versions of final drive motors with 15 or 18 bolts. Installing a new sprocket on a worn track chain drastically reduces tooth lifespan – verification of chain "stretch" is recommended. When replacing the sprocket, always use new bolts of the appropriate hardness class (usually 10.9 or 12.9) and tighten them to the torque recommended by the manufacturer.
