The 312GM700 Triple Grouser Track Shoe is a direct-fit aftermarket replacement for CAT 312 series excavators. Engineered to OEM specifications with a 171.5mm pitch and 700mm width, this shoe delivers the proven reliability that CAT 312 operators expect. Forged from 23MnB boron alloy steel, each shoe undergoes a complete heat treatment cycle — austenitizing, quenching, and tempering — followed by induction hardening on all three grouser surfaces (HRC 42-46). The wide 700mm profile provides excellent flotation and stability, particularly on soft and uneven terrain. CNC machining ensures precise bolt hole positioning for perfect track chain alignment. An ideal replacement solution for CAT 312 contractors seeking quality and value.

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.
Specifically designed for CAT 312, 312B, 312C excavators. Suitable for general construction, utility work, road maintenance, pipeline installation, and medium-duty excavation.
The 312GM700 (TG171.5B-8-700, 171.5mm pitch) is designed for 312 through 312C models. CAT 312D and newer models may use different track chain specifications. Please verify your machine's pitch measurement.
Both fit CAT312 excavators but differ in width: 312GM700 is 700mm wide while 312GM770 is 770mm wide. The wider 770mm version provides better flotation on soft ground.
