The International 175C excavator is a versatile machine widely used in construction and heavy-duty operations. Despite its reliability and solid performance, over time, users may encounter various issues. This article will explore some common problems faced by International 175C owners and provide solutions to address them.
Common Issues
The International 175C excavator is a reliable and powerful machine for various construction tasks. However, like all machinery, it may experience issues as it ages. By conducting regular maintenance, promptly diagnosing and addressing problems, and following recommended solutions, owners can significantly extend the lifespan of their equipment. Proper care and early detection of issues will ensure the International 175C continues to perform efficiently for years to come.
Common Issues
- Engine Starting Difficulties
Some users have reported issues with starting the engine, particularly in colder conditions or after prolonged periods of inactivity. This problem is typically related to insufficient battery voltage, fuel system issues, or malfunctioning starting systems.
- Low Hydraulic Pressure
The hydraulic system is crucial to the excavator’s performance. Low hydraulic pressure can lead to sluggish operation and unresponsive digging. Common causes include hydraulic fluid leaks, pump malfunctions, or issues with control valves.
- Electrical System Problems
Electrical problems in the cab, such as abnormal instrument panel readings, sensor failures, or electrical shorts, can prevent proper operation. These issues may also make it difficult for the operator to get accurate machine status information.
- Transmission Issues
Transmission problems often manifest as difficulty in shifting, unsteady transmission, or loss of power. These issues are typically related to the hydraulic system, clutch, or gearbox.
- Engine Starting Difficulties
Start by checking the battery voltage to ensure it is sufficiently charged. If the battery is low, recharge it or replace it with a new one. Next, inspect the fuel system to ensure the fuel pump and filters are not clogged, especially in cold weather. In colder climates, consider using low-temperature fuel to improve cold starts. Additionally, check the starter motor and battery wiring for any issues.
- Low Hydraulic Pressure
When hydraulic pressure is low, first check the hydraulic fluid level to ensure it is sufficient and that no leaks are present. Then, inspect the hydraulic pump to ensure it is operating properly. A pressure test may be needed to check the pump's performance. Leaks in the hydraulic control valves and pipes are also common issues that should be addressed by replacing any worn or damaged components.
- Electrical System Issues
If you encounter electrical problems, begin by inspecting the battery and wiring connections. Ensure the battery is fully charged and the wiring is secure. Check the instrument panel for any error codes or abnormal readings. Perform a full inspection of the electrical system, focusing on sensors and control units. Timely replacement of faulty components will help prevent further issues. Regular cleaning and inspection of electrical connectors are also recommended to avoid poor connections.
- Transmission Issues
For transmission problems, start by checking the hydraulic system. Ensure the hydraulic fluid is at the correct level and that the pump and valves are functioning properly. If the hydraulic system is not the issue, the problem may lie with the clutch or gearbox. Worn clutches or insufficient lubrication in the gearbox can cause transmission failures. Replacing worn parts or adding lubrication can help resolve transmission-related problems.
- Regular Inspections and Maintenance
Regular maintenance and inspections are essential to avoid unexpected failures. Regularly check the engine, hydraulic system, electrical system, and transmission. Follow the manufacturer’s recommendations for oil changes, fluid replacements, and filter maintenance to keep the machine running smoothly.
- Proper Operating Practices
Operators should adhere to correct operating procedures to reduce the risk of breakdowns. Preheat the engine and hydraulic system before operation, especially in cold weather. Avoid overloading the machine, and ensure that the workload is balanced to reduce wear on parts. Always follow the manufacturer’s operating guidelines.
- Address Small Issues Early
Small issues can lead to major breakdowns if not addressed promptly. If you notice minor issues like hydraulic fluid leaks, electrical faults, or small engine problems, take immediate action to fix them. This will help prevent larger and more costly repairs down the road.
