Product Details

Caterpillar D9N Bulldozer Master Link Technical Specifications

Specification	Details
Compatible Models	Caterpillar D9N, D9R, D9T Bulldozers
Material	35MnB Alloy Steel (Forged and Heat-Treated)
Pitch	240 mm (9.45 inches)

The main function of the Bulldozer Master Link for Caterpillar D9N

The main function of this master link is to serve as a removable connecting link (split master link) in the track chain assembly of the bulldozer.

In simple terms, it allows the track chain to be easily opened and closed, so operators or technicians can:

Install or remove the entire track chain quickly without disassembling the whole system
Perform repairs, adjustments, or track replacement with minimal downtime

It is bolted together (split design) to provide a strong, secure connection that withstands heavy pulling forces, shocks, and extreme working conditions (such as mining, construction, and earthmoving), while keeping the track aligned and functioning smoothly.

The difference between dry chain and lubricated chain

Key Features

Split Design for Easy Installation: Allows quick assembly and disassembly without special tools, minimizing field downtime.
High-Strength Alloy Steel Construction: Made from 35MnB or equivalent forged steel with heat treatment for HRC 50-58 hardness, offering excellent tensile strength and impact resistance.
Precision Engineering: Press-fit or slip-fit compatibility with sealed and lubricated track chains, ensuring smooth operation and reduced friction.
Corrosion-Resistant Finish: Advanced surface treatment to withstand harsh environments, including abrasive soils and wet conditions.
OEM Compatibility: Matches Caterpillar specifications, including pin diameter, plate thickness, and link height for perfect fit.

Compatibility and Applications

This Master Link is specifically engineered for Caterpillar D9N bulldozers but offers cross-compatibility with D9R and D9T models in similar track chain configurations. It integrates seamlessly with lubricated track link assemblies (e.g., OEM 199-5525). Suitable for:

Heavy-duty mining operations
Large-scale construction sites
Earthmoving and land clearing projects

Verify compatibility with your specific track chain pitch and part numbers for optimal performance. Not compatible with smaller Caterpillar models like D6 or D7 series.

Dozer Track Chain

We stock track chain to fit the smallest excavator to the largest D11N Cat Dozer. Track chains and track groups are available to fit all makes and models of excavators and dozers.Track chains are also available for other tracked machinery. Types of Dozer Track Chains – Dry Chains vs. Lubricated Chains When considering dozer track chains, there are two primary types: dry chains and lubricated chains. Dry chains have a lower initial cost compared to lubricated chains and are effective at keeping dirt and debris out, thereby reducing wear from contaminants. However, they require regular external lubrication to minimize wear, and without lubrication, the friction between pins and bushings can lead to faster wear. On the other hand, lubricated chains offer internal lubrication, which reduces friction and wear, resulting in a longer lifespan and lower maintenance compared to dry chains. They are ideal for heavy-duty applications where maintenance intervals are longer. The disadvantages of lubricated chains include a higher initial cost and the potential for seal failure over time, which can lead to the loss of internal lubrication.

Dozer Undercarriage Parts

Dozer undercarriage parts refer to the various components that make up the undercarriage system of a bulldozer, such as track chains, track shoes, sprockets, idlers, and rollers. These parts are crucial to the performance and durability of the bulldozer, as they support the weight of the machine, provide traction and stability, and enable it to move over various types of terrain. Regular inspection, maintenance, and timely replacement of worn or damaged undercarriage parts are essential to ensure the safety, efficiency, and longevity of the bulldozer.

Bulldozer Chain

Bulldozer chain is responsible for transmitting the power from the engine to the track, allowing the bulldozer to move forward and backward. It also helps to distribute the weight of the bulldozer evenly over the ground, providing stability and preventing sinking in soft terrain. Regular inspection and timely replacement of worn or damaged track chains is critical to ensure the safety, efficiency, and longevity of the bulldozer.

Bulldozer Idler

A Bulldozer idler is an essential component of the undercarriage system on a bulldozer. It is located at the front of the track frame and guides the track chain in its rotating motion. The front idler consists of a frame, a shaft, and a set of idler wheels that support the track chain and maintain proper tension. The idler wheel is typically made of high-strength steel and features a wear-resistant surface to ensure durability and long service life. The front idler assembly is designed to withstand the rigors of heavy-duty construction and can be customized to fit different types and models of bulldozers. The reasons why the bulldozer idler require heat treatment processes include the following points: Improving Wear Resistance and Hardness: The idler experience friction against the track links during operation, so they need to possess high wear resistance and sufficient hardness to withstand prolonged wear and impact. Heat treatment methods, such as induction hardening, can significantly enhance the surface hardness and wear resistance of the idler wheels. Enhancing Mechanical Properties: Heat treatment not only increases the hardness of the material but also improves its fatigue resistance and toughness. This is particularly important for heavy machinery like bulldozers, which often operate under harsh working conditions and require materials that can withstand repeated loads and impacts. Optimizing Material Performance: Different heat treatment processes can be optimized for specific materials to achieve the best mechanical properties. For example, by adjusting the temperature and duration of quenching and tempering, the microstructure of the material can be controlled, resulting in better overall mechanical performance. Preventing Deformation and Cracking: Internal stresses may develop during the heat treatment process, potentially leading to deformation or cracking of the workpiece. An appropriate heat treatment program can help mitigate these risks, ensuring the dimensional stability and integrity of the workpiece.
