Triple Grouser Track Shoe with 203mm Pitch and Forged 23MnB Boron Steel for CAT D6 Bulldozer Undercarriage

Product Overview

The 6Y2127 Triple Grouser Track Shoe offers a unique bulldozer undercarriage solution, combining the smooth operation of a triple grouser design with the structural strength required for dozing applications. Forged from 23MnB boron alloy steel, each shoe features three induction-hardened grouser bars that distribute wear evenly across the entire shoe width. The 700mm profile provides balanced ground pressure distribution. CNC-machined bolt holes ensure perfect chain alignment. Ideal for bulldozer operators who need traction without excessive surface damage.

Key Features

• Bulldozer Triple Grouser: Rare TG configuration for bulldozers — provides smoother operation on hard surfaces while maintaining dozing capability
• OEM Cross Reference: Direct replacement for Caterpillar 6Y2127, fits D6 and compatible bulldozer models
• Forged 23MnB Boron Steel: Induction hardened on all three grouser contact surfaces for even wear distribution
• 700mm Balanced Width: Optimal ground pressure distribution for mid-size bulldozers on mixed terrain

Technical Specifications

Factory Strength

Our manufacturing facility spans over 20,000 square meters equipped with advanced forging production lines, CNC machining centers, and automated heat treatment furnaces. We operate 8 die forging hammers (1T-10T capacity), 12 CNC turning/milling machines, and 4 continuous mesh-belt quenching & tempering furnaces with precise temperature control. Annual production capacity exceeds 500,000 track shoes. Every batch undergoes rigorous quality inspection including dimensional gauging, hardness testing (HRC), ultrasonic flaw detection, and magnetic particle inspection. We hold ISO 9001:2015 and ISO 14001:2015 certifications, with SGS/Bureau Veritas third-party inspection available upon request. Our in-house metallurgical lab ensures consistent 23MnB/25MnB boron steel composition and optimal heat treatment parameters for maximum wear resistance and impact toughness.

Quality Control Process

1. Incoming raw material inspection with spectrometer analysis
2. Forging temperature monitoring and die wear inspection
3. Post-forging dimensional check on sampling basis (1 per 50 pcs)
4. Heat treatment hardness verification (HRC 40-48 on grouser surface)
5. Magnetic particle inspection for surface crack detection
6. Final dimensional inspection with go/no-go gauges
7. Anti-corrosion coating and packing inspection

Applications

Compatible with CAT D6 series bulldozers. Suitable for mixed-terrain dozing, grading, land clearing, and construction where a balance of traction and surface protection is needed.

Frequently Asked Questions

Q1: Why triple grouser on a bulldozer?

Triple grouser on bulldozers is preferred when operating on hard, paved, or finished surfaces where a single grouser would cause excessive surface damage. It's common for bulldozers working in urban construction, waste handling, and landscaping.

Q2: Does 6Y2127 fit D6R and D6T?

Yes, 6Y2127 (TG203C-13-700) is compatible with D6R and D6T bulldozers. Its 203mm pitch matches the standard D6 track chain specification.
