Key Specifications
- Engine: The 125B is equipped with a Deutz BF6L913 diesel engine, delivering approximately 134 horsepower at 2,200 RPM. This engine provides the necessary power for demanding tasks.
- Operating Weight: The excavator has an operating weight of around 24,250 lbs (11,000 kg), making it suitable for a range of applications without compromising mobility.
- Hydraulic System: The hydraulic system operates at a flow rate of 41 GPM (155 L/min), ensuring efficient operation of the boom, arm, and bucket.
- Dimensions: The standard operating length is 32 ft 3 in, width is 10 ft 3 in, and height is 10 ft 7 in. These dimensions contribute to its stability and reach.
- Bucket Capacity: The 125B can accommodate buckets ranging from 0.76 m³ to 1.43 m³, depending on the specific model and configuration.
Despite its reliability, the Case 125B may encounter certain issues over time. Operators have reported slow hydraulic functions, which can be attributed to several factors:
- Hydraulic Pump Wear: Over time, the hydraulic pump may experience wear, leading to decreased performance. Operators have noted that the machine operates slowly despite everything working, suggesting a potential pump issue.
- Hydraulic Fluid Contamination: Contaminants in the hydraulic fluid can cause blockages and reduce efficiency. It's essential to regularly check the fluid for cleanliness and replace it as needed.
- Hydraulic Leaks: Leaks in the hydraulic system can lead to a loss of pressure and slow operation. Inspecting hoses and connections for signs of wear or damage is crucial.
- Air in the Hydraulic System: Air trapped in the hydraulic lines can cause erratic movements and reduced power. Bleeding the system can resolve this issue.
To ensure the longevity and optimal performance of the Case 125B:
- Regular Fluid Checks: Monitor hydraulic fluid levels and quality. Use the recommended Tenneco oil, known for its blue color, to maintain system integrity.
- Routine Inspections: Regularly inspect hoses, seals, and connections for signs of wear or leaks.
- Scheduled Replacements: Replace filters and fluids at intervals specified in the operator's manual to prevent contamination and ensure smooth operation.
The Case 125B excavator remains a valuable asset in the construction industry due to its durability and performance. By adhering to recommended maintenance practices and promptly addressing any issues, operators can maximize the lifespan and efficiency of this machine.
