These machines, originally designed for efficient earth-moving operations, remain popular even in modern-day applications due to their durability and reliability.
This article provides an in-depth look into the Caterpillar 955 and 933 Traxcavators, exploring their features, common issues, and best practices for maintenance and troubleshooting. Whether you're a seasoned operator, a collector, or someone looking to purchase or restore one of these iconic machines, this guide will offer valuable insights.
History and Overview of the Caterpillar 955 and 933 Traxcavators
The Caterpillar 955 and 933 models were designed in the mid-20th century and became instrumental in many construction projects worldwide. Both machines belong to the "Traxcavator" line, a blend of tractor and excavator, making them ideal for digging, lifting, and hauling operations. The "955" model, often referred to as the "small crawler loader," was particularly valued for its compact size, strong engine, and ability to operate in confined spaces.
The 933, a slightly smaller and less powerful version, also gained recognition for its versatility in small-to-medium-sized construction tasks. These models were typically equipped with a loader bucket or an excavator arm, depending on the requirements of the job.
Key features of the 955 and 933 include:
While the Caterpillar 955 and 933 are generally known for their longevity, like all machinery, they can experience a few issues over time. Below are some of the most common issues with these models and how to address them:
1. Hydraulic System Leaks
One of the most common issues reported with older Caterpillar Traxcavators is leaks in the hydraulic system. These leaks typically occur in the hoses, cylinders, or valves, and they can severely impact the machine's performance. Weak hydraulics can result in slow bucket movement or difficulty lifting heavy loads.
Solution: Regular inspection of hydraulic hoses, seals, and cylinders is crucial. Replace any worn or damaged parts and ensure that hydraulic fluid is topped up and clean. Using high-quality hydraulic oil can also prevent contamination.
2. Engine Overheating
Older models like the 955 and 933 can face overheating issues due to blocked radiators, damaged cooling systems, or low coolant levels. Overheating can cause the engine to lose power and may lead to irreversible damage if not addressed in a timely manner.
Solution: Keep the radiator and cooling system clean by regularly removing debris or dirt that may clog the system. Always monitor the coolant levels and replace the coolant at regular intervals. If overheating persists, check the radiator for any cracks or leaks.
3. Transmission Problems
Transmission issues, such as slipping gears or difficulty shifting, are common in older machines. These problems are often caused by worn-out components in the transmission system, low transmission fluid, or contamination of fluid.
Solution: Regularly check and maintain the transmission fluid levels. Flush the transmission fluid if it appears dirty or contaminated. It's essential to address any issues with the transmission promptly, as a failure to do so can result in a costly repair.
4. Electrical Failures
Electrical problems, including dead batteries, faulty alternators, and worn-out wiring, are often reported in older equipment like the 955 and 933. These issues can prevent the machine from starting or cause erratic electrical behavior during operation.
Solution: Inspect the electrical system regularly, paying attention to the battery charge, alternator condition, and the condition of electrical wiring. Clean the battery terminals to prevent corrosion and replace the battery if it shows signs of wear.
Maintenance Tips to Extend the Life of Your Traxcavator
To keep your Caterpillar 955 or 933 in top shape, regular maintenance is essential. Here are some best practices for maintaining these machines:
Although the Caterpillar 955 and 933 Traxcavators are no longer in production, they remain relevant in niche applications and are considered collectible by some heavy equipment enthusiasts. These machines continue to serve in smaller, specialized operations, particularly in environments where newer, larger equipment cannot access or operate efficiently.
For example, contractors who work in confined spaces, such as urban construction sites or narrow trenches, may still rely on the compact size and maneuverability of the 955 and 933. Additionally, these machines are often seen in restoration projects, where enthusiasts work to preserve their historical significance.
Conclusion
The Caterpillar 955 and 933 Traxcavators represent an era of construction machinery that prioritized durability, versatility, and reliability. While these models are no longer in production, they remain valuable assets for those who understand their unique strengths and limitations. Proper maintenance and regular inspection can ensure that these machines continue to perform reliably for years to come, whether in active service or as part of a collector’s restoration project.
For anyone looking to purchase a used Traxcavator or maintain one, understanding these machines’ history and common issues is vital. When properly cared for, the Caterpillar 955 and 933 can continue to serve their owners, proving that even older equipment can remain a valuable tool on the job site.

Key features of the 955 and 933 include:
- Crawler Tracks: Both models use durable crawler tracks, which provide enhanced traction on soft or uneven surfaces, reducing the risk of getting stuck and enabling better mobility on job sites.
- Hydraulic Systems: They were equipped with hydraulic systems that powered the loader or backhoe attachments, providing superior digging and lifting capabilities.
- Engine Power: Both the 955 and 933 were powered by robust Caterpillar engines designed for long-lasting performance. The 955, for example, boasted a 95 horsepower engine, while the 933 had a slightly smaller engine to suit lighter tasks.
- Versatility: These machines could be used for a variety of construction tasks, including digging, loading, and grading. The ability to swap out attachments, such as backhoes, buckets, or even specialized equipment, made them indispensable for contractors.
