Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The track chain and track shoe assembly for Komatsu D155 bulldozers is a critical undercarriage component designed to provide reliable ground traction, load-bearing strength, and durability in the harshest working conditions. Built with premium alloy steel and engineered to match OEM specifications, this track link assembly ensures that the bulldozer maintains stability and efficiency during heavy-duty earthmoving, mining, and construction operations.
Materials and Heat Treatment
To withstand extreme wear and heavy loads, the chain links and track shoes are manufactured from 40Mn, 35MnB, or 35SiMn high-strength alloy steel. Each component undergoes advanced forging, quenching, and tempering to achieve optimal hardness, typically reaching HRC 48–56 in wear surfaces while retaining core toughness. This balance prevents premature cracking while ensuring extended service life.
- Track Chain Links: Forged and precision-machined to achieve accurate pitch dimensions and strong bearing capacity.
- Pins and Bushings: Produced with alloy steel and subjected to induction hardening to resist wear and elongation.
- Track Shoes: Manufactured with deep heat-treated surfaces to handle abrasive ground conditions.
Key Features and Advantages
- OEM-Compatible Design: Perfect fit for Komatsu D155 bulldozers and interchangeable with original assemblies.
- Extended Wear Life: Hardened pins, bushings, and shoes reduce maintenance intervals.
- Superior Ground Grip: Wide and reinforced track shoes provide strong traction in muddy, rocky, or sandy terrain.
- Cost-Effective Replacement: Ensures long service life while reducing undercarriage operating costs.
Manufacturing Process
The Komatsu D155 track chain and track shoe assembly is manufactured through a rigorous production process:
- Raw Material Selection – Strictly sourced alloy steel with consistent chemical composition.
- Forging and Machining – Each link, pin, and bushing is forged and CNC machined for dimensional accuracy.
- Heat Treatment – Advanced induction quenching and tempering to enhance wear resistance.
- Assembly and Press Fitting – Pins and bushings are press-fitted with precise interference to prevent oil leakage and elongation.
- Track Shoe Installation – Shoes are bolted securely to chain links with high-strength track bolts and nuts.
- Quality Testing – Final assembly undergoes load tests, hardness checks, and dimensional inspection.
Track Link Forging & Machining
The track links are manufactured using high-strength 35MnB steel and undergo precision heat treatment to improve surface hardness and internal toughness. This process enhances resistance to impact, wear, and deformation, ensuring reliable performance under heavy-duty working conditions.
Track Link Assembly with Pins & Bushings
Each track link is carefully assembled with pins and bushings under controlled conditions to ensure proper fit and alignment. Accurate assembly minimizes internal friction and ensures smooth chain movement, which is critical for the durability of Komatsu D155 undercarriage systems.
Surface Induction Hardening Process
During this stage, the track chain undergoes induction hardening, visible through high-temperature sparks. This process significantly strengthens the wear surfaces of the links, pins, and bushings, improving abrasion resistance and extending the overall service life of the track chain.
Anti-Corrosion Coating & Painting
After final inspection, the track chain is treated with anti-corrosion coating and painted to protect against rust and environmental damage during storage and transportation. This coating also improves product appearance and ensures readiness for immediate installation upon delivery.
Application Scenarios
The D155 bulldozer track chain and track shoe assembly is engineered for use in:
- Mining Operations – Handling abrasive rocks and high-impact digging.
- Road and Dam Construction – Offering stability on uneven ground.
- Forestry and Land Clearing – Ensuring strong grip on muddy or soft soil.
- Quarrying and Heavy Earthmoving – Withstanding constant impact and load cycles.
Compatibility and OEM Reference
This track chain and shoe assembly is suitable for:
- Komatsu Bulldozer Models: D155A, D155AX, D155AX-6 and similar series.
- OEM Part Numbers: 17A-27-77110, 175-32-02563 (Chain track plate assembly).

Maintenance Recommendations
To maximize the lifespan of your Komatsu D155 track chain and shoe assembly:
- Regularly inspect pins and bushings for wear and measure chain pitch elongation.
- Maintain proper track tension to reduce stress on links and rollers.
- Lubricate bushings if applicable (depending on sealed/lubricated type).
- Replace track shoes when the grouser height is significantly worn down.
