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 CAT 304E track group assembly, also known as the track chain with shoes assembly, is one of the most important components of the excavator undercarriage. It directly supports the machine's weight, transfers driving power to the ground, and allows the excavator to travel efficiently across various terrains. As a professional replacement track group for Caterpillar CAT 304E excavators, this assembly integrates high-strength track links, hardened pins and bushings, and durable track shoes into one complete unit. Replacing the entire track group instead of individual worn components often improves undercarriage performance and reduces installation time.
Superior Traction and Ground Stability
Every E320 chain undergoes a carefully controlled production process to ensure long-lasting performance:
- Forged Track Links: High-strength alloy steel is used to forge each link for superior toughness.
- Heat-Treated Pins & Bushings: Deep induction hardening improves wear resistance and shock absorption.
- CNC Machining: Ensures precision pitch (link-to-link distance) and bushing concentricity for low friction and smooth operation.
- Lubricated or Dry Sealed Options: Available in both greased (sealed & lubricated) or dry variants depending on your project needs.
- Surface Protection: Final coating or painting prevents rust and prolongs shelf and service life.
Highlighting the Process
We provide actual production visuals to give you transparency and confidence:
Track Link Heat Treatment & Surface Processing
Each track link undergoes controlled heat treatment and surface processing to improve hardness, wear resistance, and fatigue strength. This process enhances the durability of the chain links and helps the undercarriage withstand continuous impact and heavy working conditions.
Precision Track Chain Assembly
Pins, bushings, and track links are assembled using precision equipment to ensure consistent pitch accuracy and proper alignment. The carefully assembled chain provides smooth engagement with the sprocket and reduces uneven wear throughout the undercarriage system.
Track Shoe Forming and Finishing
The track shoes are manufactured from high-quality steel and processed to achieve excellent strength and resistance to deformation. Surface finishing and dimensional inspections ensure that each shoe delivers reliable traction and stable machine movement across various ground conditions.
Final Assembly, Inspection & Shipment Preparation
Every completed track group is thoroughly inspected, coated for protection, and carefully packaged before entering the warehouse. This final stage ensures that customers receive high-quality, installation-ready undercarriage assemblies with reliable performance and long service life.
Durable Materials for Extended Service Life
The track links are manufactured from high-strength alloy steel and undergo heat treatment to improve wear resistance and structural integrity. Pins and bushings are processed through controlled hardening procedures to withstand continuous friction and impact loads.
The track shoes are produced using high-quality steel plates with excellent toughness and resistance to deformation. This combination of materials helps extend service life even under frequent travel and demanding operating conditions.
