Caterpillar 955 Track Compatibility: What Other Equipment Uses the Same Tracks?

[MikePhua]

The Caterpillar 955 series, including its iconic track loader, has been a staple in construction and heavy machinery for decades. Known for its durability and power, the CAT 955 is used in a variety of applications, from excavation to grading and lifting. One of the key components that contribute to its performance is the undercarriage, particularly the tracks.
However, many operators and fleet managers often find themselves in situations where they need to replace or maintain the tracks on their machines. A common question that arises is whether other equipment models use the same tracks as the 955. Understanding the compatibility of tracks between different machines can save time and money, especially when sourcing replacement parts or considering used equipment for parts.
Understanding the Caterpillar 955 and Its Track Specifications
The Caterpillar 955 is a well-known and versatile track loader that has been around for many years. It comes in several variations, including the 955L, 955K, and earlier models, all of which are distinguished by their track systems. The tracks on the 955 are part of the undercarriage system that helps distribute the machine’s weight, improving its performance in soft or uneven terrain.
Typically, the track size on the CAT 955 is a 320 mm width and features a pitch of 152.4 mm. This is considered a medium to heavy-duty track, suitable for a variety of earthmoving tasks. The 955’s undercarriage is designed to provide both stability and maneuverability, a key feature when working on construction sites with rough or loose soil.
For those looking to replace or repair their 955’s tracks, it’s important to know which other equipment models use the same dimensions and track system. This not only increases options for sourcing parts but also opens up the possibility of using equipment from other brands with similar track systems.
Equipment Models Using the Same Tracks as the CAT 955

1. Caterpillar 977 Series Track Loaders:
   The Caterpillar 977 series, including models like the 977K, 977L, and others, uses a very similar undercarriage system to the 955. These machines share the same track size and configuration, making them ideal candidates for track compatibility. The 977 is a larger machine compared to the 955, but the track system remains consistent across the two, making it a good source for spare parts.
   
2. Caterpillar 963 Track Loader:
   The Caterpillar 963 series track loaders, which are successors to the 955, also use similar tracks. While the 963 is a more modern and larger machine, certain models in the 963 series can use the same track size, providing another avenue for sourcing replacement tracks.
   
3. Caterpillar 941 and 943 Tracked Loaders:
   Older Caterpillar tracked loaders, like the 941 and 943 models, are another source for compatible tracks. These machines were produced around the same era as the 955, and their undercarriage systems often share components, including tracks. The 941 and 943 loaders are smaller than the 955, but they can still use tracks of a similar size and pitch.
   
4. International Harvester TD-25:
   Although not a Caterpillar machine, the International Harvester TD-25 bulldozer uses a track system that is compatible with the CAT 955. This model was produced during the same time period and was often used for similar tasks in construction and agriculture. Operators looking for more economical track options might consider sourcing tracks from the TD-25 for their CAT 955.
   
5. Komatsu D50A Crawler Tractor:
   The Komatsu D50A, another mid-range crawler tractor, also uses a similar track width and pitch to the CAT 955. While the track system isn’t identical, the compatibility in size makes it a good alternative for sourcing replacement parts.
   

Why Track Compatibility Matters
Track compatibility is more than just a convenience—it can significantly impact operational efficiency and cost-effectiveness. The main advantages of understanding which machines use the same tracks as the CAT 955 include:

• Cost Savings on Parts: By knowing other models that use the same tracks, operators and fleet managers can take advantage of used or aftermarket parts, reducing costs compared to buying new from the original manufacturer.
  
• Improved Parts Availability: Sometimes, certain models may have limited availability of parts due to age or model discontinuation. Knowing which other models share the same track system increases the chances of finding compatible parts from different sources.
  
• Easier Maintenance and Repairs: If a track failure occurs, having knowledge of which other machines share the same tracks allows for faster sourcing of replacement parts and minimizes downtime on job sites.
  

Challenges of Using Non-OEM Tracks
While using tracks from different equipment models can provide cost-saving opportunities, there are also challenges that operators should be aware of:

1. Quality Control: Aftermarket or used tracks might not always meet the same standards as OEM (original equipment manufacturer) parts. This can lead to faster wear, higher maintenance costs, or even performance issues.
   
2. Compatibility Issues: Although the tracks may have similar dimensions, small differences in design or fitment could lead to installation issues. It's important to ensure that the track links, sprockets, and other components align properly with the undercarriage system.
   
3. Warranty Concerns: Using non-OEM parts, especially if sourced from different brands or models, may void warranties or service agreements with the original manufacturer. Always check warranty details before choosing alternative parts.
   

Real-World Example: A Construction Site Solution
A construction company with a fleet of CAT 955 track loaders faced a significant repair issue when their machines’ tracks started showing signs of heavy wear. Rather than waiting for weeks for OEM parts to arrive, the company’s mechanic researched which other machines shared the same track specifications. They discovered that the CAT 977 and Komatsu D50A used similar tracks and were able to find a reliable used set from a nearby dealer.
By sourcing compatible tracks from different models, the company was able to minimize downtime and keep their project on schedule, all while saving money on parts. This case highlights the value of knowing the cross-compatibility of track systems and the importance of keeping a network of suppliers in mind.
Conclusion: Maximizing Efficiency with Track Compatibility
Understanding which equipment models use the same tracks as the CAT 955 opens up a range of possibilities for sourcing parts, reducing costs, and ensuring operational continuity. While the CAT 955 is a unique machine in its own right, several models share its track system, providing valuable alternatives for operators and fleet managers.
Whether you're dealing with maintenance on a CAT 955 or looking for cost-effective solutions for parts, exploring track compatibility across various models can help keep your equipment running smoothly and efficiently. By considering different manufacturers and models, operators can find reliable alternatives, saving time and money without compromising on performance.
