The Case 125B Excavator stands as a testament to Case Construction Equipment's commitment to delivering robust and reliable machinery for the construction industry. Manufactured from 1985 to 2015, this model has been a staple in various heavy-duty applications, from urban construction sites to rural infrastructure projects.
Development and Evolution
Case Construction Equipment, a division of CNH Industrial, traces its origins back to 1842. Over the decades, the company has been at the forefront of innovation in construction machinery. The 125B model was introduced as part of Case's efforts to provide versatile and powerful excavators capable of handling a wide range of tasks. Its design incorporated feedback from operators and advancements in hydraulic technology, ensuring efficiency and durability.
Technical Specifications
The Case 125B Excavator is equipped with a Deutz BF6L913 diesel engine, delivering 134 horsepower at 2,200 RPM. This powertrain is complemented by a two-speed hydrostatic transmission, allowing for smooth transitions between different operational speeds. The machine's operating weight is approximately 24,250 lbs (11,000 kg), making it suitable for both heavy lifting and precise digging operations.
Key specifications include:

• Maximum Digging Depth: 19 ft (5.8 m)
  
• Bucket Capacity: 0.87 cubic yards (0.67 m³)
  
• Hydraulic Flow: 41 GPM (155 L/min)
  
• Track Length: 14 ft 8 in (4.47 m)
  
• Track Width: 30 in (0.76 m)
  

These features enable the 125B to perform effectively in various soil conditions and construction scenarios.
Performance and Capabilities
The Case 125B Excavator is designed for versatility and efficiency. Its hydraulic system offers a maximum breakout force of 154 kN, allowing it to handle tough materials and challenging digging tasks. The machine's maximum horizontal reach is 10.15 meters, providing operators with extended reach capabilities for tasks such as trenching and material handling.
The 125B's design emphasizes operator comfort and control. The spacious cab offers excellent visibility and is equipped with ergonomic controls, reducing operator fatigue during extended work periods. Additionally, the machine's undercarriage is designed for stability, ensuring safe operation on uneven terrain.
Maintenance and Longevity
Maintaining the Case 125B Excavator is straightforward, thanks to its user-friendly design and readily available parts. Regular maintenance, such as checking hydraulic fluid levels, inspecting the undercarriage, and servicing the engine, is essential to ensure the machine's longevity and optimal performance.
Operators have reported that with proper maintenance, the 125B can remain operational for thousands of hours. For instance, a 1990 model with approximately 4,500 hours on the clock was still in good working condition, demonstrating the machine's durability over time.
Common Issues and Troubleshooting
Like all machinery, the Case 125B Excavator may encounter issues over time. Common problems reported by operators include hydraulic system malfunctions and engine performance issues. For example, some users have noted that when curling the bucket in and holding a pressure of 2,700 to 2,840 psi, the engine should maintain a minimum of 2,150 RPM. Failure to do so may indicate issues with the hydraulic system or engine performance.
To troubleshoot such issues, it's recommended to start by checking the bucket's performance and then proceed to test the main relief valves. Ensuring the engine operates at the correct RPM during load conditions is crucial for diagnosing potential problems.
Market Presence and Usage
The Case 125B Excavator has been widely used in various sectors, including construction, agriculture, and municipal projects. Its versatility and reliability have made it a popular choice among contractors and operators. The machine's ability to handle diverse tasks, from digging and lifting to material handling, has contributed to its enduring presence in the market.
Conclusion
The Case 125B Excavator exemplifies Case Construction Equipment's dedication to producing high-quality, durable machinery. Its combination of power, versatility, and operator comfort makes it a valuable asset for a wide range of construction and heavy-duty applications. With proper maintenance and care, the 125B can continue to serve operators effectively for many years, underscoring its status as a reliable workhorse in the construction industry.
