Over the years, the 966B has been praised for its solid performance, ease of maintenance, and longevity, making it a sought-after option on the used equipment market.
Specifications and Features of the CAT 966B
The CAT 966B is a medium-sized wheel loader with a standard operating weight of approximately 17,000 pounds, though this can vary slightly depending on attachments and configuration. It is powered by a diesel engine, which has a power output of about 150 horsepower. This power allows the 966B to handle heavy lifting, digging, and material handling tasks with ease.
Key specifications of the 966B include:
  • Engine Type: Diesel
  • Horsepower: 150 hp
  • Operating Weight: Around 17,000 lbs
  • Bucket Capacity: 3.0 to 4.0 cubic yards (depending on configuration)
  • Max Lift Height: 10-12 feet
  • Max Bucket Breakout Force: 18,000 lbs
  • Tipping Load: 10,000-11,000 lbs
  • Transmission: Powershift
  • Loader Arm Type: Z-bar
The 966B's bucket capacity can be adjusted based on the specific needs of the operator, providing versatility for different applications. Its lift height and breakout force are designed to allow efficient loading, unloading, and material handling. Additionally, the Powershift transmission offers smooth shifting and durability, making the loader more efficient and easier to operate.
Performance and Handling
The CAT 966B is built to tackle demanding tasks with ease. Whether moving large volumes of dirt, sand, gravel, or aggregate, the 966B is known for its strong performance in various environments.
The Z-bar linkage system on the loader arm allows the operator to achieve a high lift height and strong breakout force, which is essential for digging and lifting heavy materials. The lifting and dumping action is powerful, ensuring that materials can be loaded or unloaded efficiently. The machine is particularly noted for its stability when handling large, heavy loads, thanks to its well-designed hydraulics and robust undercarriage.
In terms of fuel efficiency, the CAT 966B offers a balance between power and economy. While older models may not have the advanced fuel-saving technologies found in newer loaders, its well-engineered diesel engine ensures that operators can complete tasks without excessive fuel consumption.
Advantages of the CAT 966B
  1. Reliability: One of the standout features of the 966B is its reliability. Many operators report that with regular maintenance, these machines can run for thousands of hours without major breakdowns. This makes the 966B a good investment for both long-term use and resale.
  2. Ease of Maintenance: The CAT 966B has been designed with serviceability in mind. Access to major components like the engine, hydraulics, and cooling systems is relatively easy, allowing for efficient servicing and repairs. This ease of maintenance reduces downtime, ultimately improving productivity.
  3. Versatility: The CAT 966B can be fitted with a variety of attachments, including forks, buckets, and grapples, to perform a range of tasks beyond just material handling. This makes the machine suitable for construction sites, quarries, and even scrap yards.
  4. Operator Comfort: Although the 966B is an older model, it still provides a relatively comfortable operating environment. The operator's cabin is spacious, and controls are easy to reach, making the machine suitable for long hours of work.
  5. Proven Track Record: Many operators and fleet owners appreciate the CAT 966B for its long-standing reputation in the field. Its durability and consistent performance have earned it a place in numerous fleets worldwide.
Common Issues and Troubleshooting
While the CAT 966B is known for its durability, like any piece of machinery, it can experience issues, especially if it's an older model. Some of the most common issues reported by operators include:
  1. Hydraulic Leaks: Hydraulic components in the 966B, particularly the cylinders and hoses, may experience leaks over time. Regular inspections are needed to ensure the system is functioning optimally.
  2. Engine Overheating: Some operators have reported overheating issues, particularly if the cooling system is not maintained properly. Regular checks of coolant levels and the radiator are essential.
  3. Transmission Problems: Given the age of many CAT 966B models, transmission issues can arise, especially with the Powershift system. Regular fluid changes and careful monitoring of the transmission system can help mitigate these problems.
  4. Wear on the Bucket: The bucket, being a frequently used component, can experience wear, especially when handling abrasive materials. Replacement or welding may be necessary for continued optimal performance.
Final Verdict: Is the CAT 966B a Good Machine?
The CAT 966B is widely considered a reliable and capable machine that holds its value well, especially in the used equipment market. For those in the construction or mining industries, it offers solid performance and longevity. While it may not have the advanced technology and fuel efficiency of newer models, its rugged design and ease of maintenance make it a good option for those looking for a dependable wheel loader.
When considering purchasing a CAT 966B, prospective buyers should pay attention to the condition of the machine, especially with respect to its engine, hydraulics, and transmission.
