228mm Pitch Single Grouser Track Shoe in 25MnB Boron Alloy Steel for Liebherr PR764 Bulldozer Undercarriage

Product Overview

The 228-1M Single Grouser Track Shoe is a specialized aftermarket component engineered for Liebherr PR764 and 688 bulldozers. Manufactured to European OEM dimensional specifications, this 228mm pitch track shoe features a heavy-duty single grouser design optimized for the demanding operating conditions of quarry and mining environments. Forged from 25MnB boron alloy steel using precision die tooling, each shoe achieves the tight dimensional tolerances required by Liebherr undercarriage systems. Induction hardening on the grouser tip (HRC 46-50) ensures extended wear life in abrasive rocky conditions. An essential replacement solution for Liebherr heavy equipment operators seeking OEM-quality performance at competitive aftermarket pricing.

Key Features

• Liebherr PR764 Specific: Engineered for Liebherr PR764 and compatible 688 model bulldozers with 228mm pitch track chains
• European Machine Compatibility: Designed to European OEM specifications with metric bolt patterns and dimensional tolerances
• Forged 25MnB Steel: Heavy-duty forging with enhanced grouser tip induction hardening for extended service in rocky conditions
• 610mm Optimized Width: Balanced profile providing excellent traction without excessive ground pressure

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

Designed for Liebherr PR764, 688, and compatible bulldozer models. Applications: quarry operations, mining support, heavy construction, landfill, and rocky terrain dozing.

Frequently Asked Questions

Q1: Is this compatible with CAT models?

No, the 228mm pitch is specific to Liebherr PR764 and 688 bulldozers. CAT bulldozers use different pitch sizes (203mm, 216mm, 260mm). These dimensions are not cross-compatible.

Q2: Do you stock Liebherr-specific undercarriage parts?

Yes, we maintain inventory for Liebherr PR734, PR744, PR754, and PR764 bulldozer undercarriage components including track shoes, rollers, idlers, and sprockets.
