Description

OEM-Quality Caterpillar D11T Heavy-Duty Track Groups & Chains

Maximize traction, prevent pin walking, and eliminate premature pitch extension on your flagship production dozer with heavy-duty Caterpillar D11T Track Groups and Track Chains. Precision-engineered specifically for Caterpillar D11T and D11T CD (Carrydozer) mining tractors operating in severe elevated sprocket environments, these track groups withstand maximum drawbar pull, extreme ripping shock, and abrasive high-wall mining conditions.

Utilizing Caterpillar’s proven Positive Pin Retention (PPR) technology alongside Sealed and Lubricated Track (SALT) architecture, these chains mechanically lock the link to the pin to preserve internal oil lubrication films, preventing joint movement under extreme torsional stress.

Key Features & Benefits

  • Positive Pin Retention (PPR) Interlocking Links: Mechanically locks the link to the pin to completely eliminate axial pin motion (pin walking) and joint play under severe high-impact ripping loads.

  • Sealed & Lubricated Track (SALT) Core: Synthetic oil permanently coats internal pin and bushing wear surfaces, eliminating internal friction, galling, and pitch extension.

  • Extra-Tall Induction-Hardened Link Profiles: Deep-hardened alloy steel links feature expanded rail height to provide maximum wear life, structural rigidity, and resistance to bottom roller scalloping.

  • Extreme Service (ES) Single-Grouser Shoes: Forged from high-tensile, heat-treated alloy steel to resist bending, cracking, and corner spalling when ripping hard granite, basalt, or limestone.

  • Heavy-Duty Split Master Links: Precision-machined split master link design allows fast, secure track installation and servicing without requiring heavy hydraulic pin-press equipment on the bench.
