🧠 How It Works
The drive sprocket is bolted to the travel reducer’s output flange. As the hydraulic travel motor turns the reducer, the sprocket rotates and engages with the track chain’s pin bushings. Each tooth pushes the track forward, translating engine power into ground movement. A correctly matched tooth profile is critical — too much clearance causes chain skipping and rapid wear; too little causes binding. Our OEM-matched profile ensures smooth rolling contact, reduced noise, and maximum chain life.
