The Caterpillar Bulldozer Track Link Assembly is a heavy-duty undercarriage component designed to connect track shoes and support stable crawler movement. Working together with the sprocket, track rollers, front idlers and track shoes, the track link assembly helps transfer driving force to the ground while supporting the operating weight of the bulldozer.

Caterpillar identifies track links and link assemblies as key undercarriage components. A complete link assembly provides a rail for the machine to travel on, supports machine weight and provides the mounting location for track shoes.

Xiamen Doozer supplies replacement Caterpillar bulldozer track link assemblies for different machine models and undercarriage configurations. Depending on the application, track chains can be supplied in General Duty, Heavy Duty or other configuration-specific designs. Exact link count, pitch, bushing diameter, master-link design and shoe-bolt dimensions should be confirmed according to the machine model and serial number.

Product Specifications

Reliable Bulldozer Undercarriage Replacement

Track link assemblies operate under continuous load and repeated contact with the sprocket and rollers. Worn pins, bushings or link rails can increase track movement and accelerate wear throughout the undercarriage system.

Caterpillar offers different undercarriage configurations according to machine model, application and ground conditions, including General Duty and Heavy Duty systems. Cat also notes that selecting the correct undercarriage depends on the machine, working conditions, application severity and expected operating hours.

When replacing a track link assembly, it is therefore recommended to inspect the track shoes, sprocket, bottom rollers, carrier rollers, front idler and track adjuster at the same time. Matching the complete undercarriage system can help maintain proper track alignment and reduce premature component wear.

Track Link Assembly Options

Xiamen Doozer can supply different track-chain configurations according to the machine and working conditions.

Sealed and Lubricated Track (SALT): Helps retain lubricant inside the track joint and reduce abrasive contamination.

General Duty Track: Suitable for general earthmoving and balanced operating conditions.

Heavy-Duty Track: Designed for more demanding applications where increased wear resistance and durability are required.

For example, Caterpillar’s official catalog includes link assemblies with different specifications such as 49 sections and 215.9 mm pitch and 44 sections and 215.9 mm pitch, demonstrating why the exact machine configuration must be confirmed before ordering.

Fitment Verification

To identify the correct Caterpillar bulldozer track link assembly, please provide:

• Caterpillar machine model
• Serial number
• Original track link part number
• Number of links per side
• Track pitch
• Track shoe width
• Bushing outside diameter
• Master-link configuration
• Photos of the existing track chain

This information helps confirm the correct link assembly and prevents compatibility issues caused by differences between undercarriage configurations.
