Product Details

Dozer undercarriage parts

Caterpillar D10 master links product technical specifications:

Product Name: Heavy Duty Master Track Link (Split Link)

OEM Part Number: 4680109

Compatible Equipment: Caterpillar D10, D10T, D10T2, D10N, D10R Bulldozers

Why Choose Our 4680109 Master Link?

1. Superior Forging & Metallurgy

We use premium alloy steel (35MnB) forged to exacting standards. Unlike cast alternatives, our forged links eliminate internal porosity, providing the structural integrity required for bulldozer undercarriage parts operating in rocky or abrasive terrains.

2. Deep Case Hardening (52-58 HRC)

To combat external wear, our links undergo an automated induction hardening process.

Surface Hardness: 52-58 HRC.
Effective Case Depth: Up to 12mm, ensuring the link resists "mushrooming" and abrasive wear over thousands of service hours.

3. Precision "Split Link" Design

The 4680109 is a serrated split-style master link. Our CNC machining ensures that the serrated teeth mate perfectly, preventing "walking" or loosening of the track shoe bolts under high torque—a common failure point in low-quality aftermarket parts.

The differences between dry track chains and lubricated track chains

First, you can easily distinguish between lubricated track chains (oil chains) and dry track chains by appearance: lubricated chains have a grease fitting (oil fill hole) on the track pin, while dry chains do not.

Second, lubricated chains are typically equipped with master links, and although dry chains may also include master links for easier installation in some cases, this is not the primary difference between the two.

Third, some high-end lubricated track chains incorporate PPR technology (Positive Pin Retention).

For many large bulldozers, PPR-equipped lubricated track chains are strongly recommended or even standard, including:

Caterpillar: D8T, D9T, D10T, D11T
Komatsu: D275, D355, D375, D475

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.
