The Sprocket Segment for Caterpillar D6D Bulldozer is a precision-engineered undercarriage component designed specifically for Caterpillar D6D, D6C, and D6G track-type tractors. As the critical drive component of the undercarriage system, the sprocket segment transfers engine torque through the track chain to propel the bulldozer forward, engaging directly with the track links to create motion. This segmented design allows for cost-effective replacement—individual worn segments can be replaced without the need for a full sprocket change, significantly reducing downtime and maintenance costs.

Manufactured from high-grade 50Mn or 40MnB alloy steel through precision forging and CNC machining processes, this sprocket segment delivers exceptional structural integrity and impact resistance. The teeth undergo full-surface induction hardening and heat treatment, achieving a surface hardness of HRC 53-58 with a hardening depth of 8-12mm. This deep, uniform hardened layer ensures long-lasting engagement with the track links under heavy load conditions and provides wear resistance that maximizes service life.

Each D6D sprocket segment features 5 teeth and is secured with 5 bolts, with a complete set consisting of 5 segments per drive wheel. The track pitch is 202.8mm (approximately 203mm) , ensuring precise OEM-spec fitment. Precision-machined mounting holes guarantee accurate bolt fit and stable installation. An anti-corrosion coating provides rust resistance in wet or abrasive environments.

Whether operating in mining, heavy construction, land clearing, or forestry applications, the Caterpillar D6D sprocket segment delivers the durability, reliability, and performance needed to keep your equipment operating at peak efficiency.
