Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The track chain is the backbone of the D6R’s undercarriage system, connecting the track shoes and transmitting torque from the sprocket to the ground. It ensures that the bulldozer maintains traction, track alignment, and power efficiency across challenging terrains like rock, clay, or loose soil.
Our D6R track chain assembly is designed to meet high-load, high-impact working conditions while minimizing internal friction, noise, and wear. This results in longer machine uptime, smoother movement, and lower lifecycle cost.
Production Process: How Our D7R Chains Are Made
Each D7R track chain is built through strict, multi-stage manufacturing:
- Link Forging & Heat Treatment – Each link is hot-forged from alloy steel (typically 35MnB or 40Mn2), then heat-treated to achieve surface hardness around HRC 52–58.
- Pin & Bushing Precision Machining – High-grade 40Cr pins and bushings are induction hardened and ground for dimensional accuracy and long wear life.
- Sealed & Lubricated Design (Optional) – Greased bushing systems reduce internal friction, extending service intervals and lowering maintenance costs.
- Surface Coating – Chains are treated with anti-corrosion black paint or phosphate finish, ensuring protection during storage and usage.
- Rigorous QC Inspection – Each link assembly is checked for pitch, hardness, roundness, and structural integrity before delivery.
Compatibility and OEM Reference
Designed to fit Caterpillar D6R and D6R Series II bulldozers, this track chain is also compatible with D6H and early D6T undercarriage configurations (please verify track pitch and link type before ordering).
We offer the following OEM-compatible track chain options for D6 series:
- D6H Track Chain (39 Links) – 8E4326
- D6R Track Chain (38 Links, Dry Type) – 6I-9668
- D6R Track Chain – 6I-9668 / 424-0844
- D6C/D Track Chain (36 Links, Lubricated Type) – 3P1118
- D6M XL Track Chain (40 Links, Lubricated Type) – 1102976
All track chains are manufactured according to OEM standards, ensuring accurate fitment, stable performance, and long service life in demanding working conditions.
If you are unsure about compatibility, simply provide your machine’s serial number, part number, or technical drawing. Our team will assist in confirming the correct configuration to ensure a precise match and hassle-free installation.
Photo Overview of Our Workshop
Each D6R chain is produced using a rigorous, step-by-step process:
Track Link Forging & Machining
The raw track links are forged into form, then machined to ensure uniform pitch and hole alignment. Precision is essential for proper sprocket and bushing engagement.
Pin and Bushing
Hardened pins are inserted between the links to create a flexible, load-bearing chain. The sealing system prevents grease leakage and contaminant ingress.
Painting & Surface Coating
After assembly, the entire chain is cleaned and painted with industrial-grade coatings to protect against rust, humidity, and chemical corrosion on job sites.
Final Inspection & Packaging
Before shipping, the chains undergo dimensional checks and torque verification. Chains are then packed securely on wooden pallets or steel frames to avoid deformation.
