Komatsu PC100-3 Excavator Undercarriage Parts | Front Track Sprocket & Drive Gear

Restore optimal power transfer and track alignment for your Komatsu PC100-3 excavator with our heavy-duty replacement Track Sprocket (Drive Gear). As the critical link between the final drive motor and the track chain, a worn sprocket can lead to poor traction, accelerated chain wear, and costly downtime. Manufactured to exacting OEM standards, this product offers a cost-effective and highly reliable alternative to keep your equipment running at peak performance.

• Superior Material & Durability: Forged from high-quality 40Mn / 50Mn alloy steel, our track sprockets undergo a deep induction hardening process. This significantly enhances the tooth profile's surface hardness and core toughness, providing outstanding resistance to wear, impact, and deformation in harsh, abrasive environments.
• Precision Machining: CNC-machined to strict tolerances, ensuring a seamless, drop-in fit for the Komatsu PC100-3. The precise tooth profile guarantees smooth engagement with the track chain links, preventing premature stretching, reducing vibration, and extending the overall lifespan of your undercarriage components.
• Optimized Power Transfer: Designed to distribute the excavator's driving force evenly across the track chain, our sprockets minimize internal friction and prevent track derailment, ensuring stable and efficient operation on uneven terrains.
• Strict Quality Control: Every sprocket undergoes rigorous dimensional and hardness testing before leaving our facility. Backed by our commitment to quality, we provide fast global shipping and dedicated technical support to keep your job site running smoothly.
