- Robust and Durable Design
Built to withstand harsh conditions, the Kobelco 905 LC-2 is constructed using high-quality materials that ensure durability and long-lasting performance. The undercarriage is designed to handle heavy loads while maintaining stability, making the machine ideal for various construction and mining applications. Its tough exterior is built to resist wear and tear, even in the toughest working environments.
While the Kobelco 905 LC-2 is a reliable machine, there are several common issues that operators and fleet managers may encounter over time. Knowing how to troubleshoot these problems can save valuable downtime and repair costs.
- Hydraulic System Problems
One of the most common issues with the Kobelco 905 LC-2 is hydraulic system problems. This can manifest as sluggish or unresponsive hydraulics, poor lifting power, or uneven movements of the boom or bucket. Several factors can contribute to hydraulic system issues, including low hydraulic fluid levels, air trapped in the system, or faulty valves or pumps.
Troubleshooting Tip:
First, check the hydraulic fluid levels and top them up if needed. If the fluid is low, inspect for potential leaks in hoses, seals, or connections. Bleed the system if necessary to remove any trapped air. Additionally, inspect the hydraulic filters and clean or replace them if clogged. If these steps do not resolve the issue, it may be necessary to replace the hydraulic pump or valve.
- Engine Overheating
Overheating is another common problem with the Kobelco 905 LC-2, particularly when working in hot climates or during heavy-duty tasks. Overheating can be caused by a number of factors, including a dirty radiator, clogged cooling fins, low coolant levels, or a malfunctioning thermostat.
Troubleshooting Tip:
Start by checking the coolant levels and topping them up if necessary. Clean the radiator and cooling fins to remove any dirt or debris that may be blocking airflow. Check the condition of the thermostat and replace it if needed. It is also essential to check the water pump and ensure that it is functioning properly to maintain proper coolant circulation.
- Electrical Failures
Electrical issues, such as failure of the starter motor, alternator, or fuse, can cause the Kobelco 905 LC-2 to stop operating. A common issue is the failure of the alternator, which can lead to battery drainage and prevent the machine from starting.
Troubleshooting Tip:
Check the battery voltage and ensure that it is fully charged. Inspect the alternator for any signs of damage or wear. If the alternator is not charging the battery properly, it may need to be replaced. Additionally, check all fuses and wiring connections to ensure they are intact and free from corrosion.
- Undercarriage Wear
The undercarriage of the Kobelco 905 LC-2 is designed to withstand heavy loads, but excessive wear can occur due to rough terrain or improper maintenance. Worn-out tracks, rollers, or sprockets can lead to decreased stability, increased fuel consumption, and compromised performance.
Troubleshooting Tip:
Inspect the undercarriage regularly for signs of wear, such as worn tracks, loose bolts, or damaged rollers. If the tracks are excessively worn, consider replacing them. Lubricate the undercarriage components regularly to reduce friction and prevent premature wear. Keep the undercarriage clean from debris and mud, as buildup can lead to accelerated wear.
Routine maintenance is essential for keeping the Kobelco 905 LC-2 in top working condition and extending its lifespan. Below are some essential maintenance practices that will help ensure the machine operates smoothly:
- Regular Fluid Checks
Check and maintain the engine oil, hydraulic fluid, and coolant regularly. Ensure that all fluid levels are within the recommended range and top them up as needed. Use the correct grade of fluids as specified by the manufacturer to ensure optimal performance.
- Replace Filters on Schedule
The Kobelco 905 LC-2 has several filters, including the engine oil filter, hydraulic filters, and air filter. These filters should be replaced at regular intervals to prevent contamination and ensure smooth operation. Clogged filters can restrict fluid flow, leading to system inefficiencies and potential failures.
- Inspect and Clean Air and Fuel Systems
Clean the air filter periodically to ensure proper airflow to the engine. A clogged air filter can restrict the engine’s performance and lead to overheating or poor fuel efficiency. Additionally, inspect the fuel system for any leaks or blockages to prevent fuel-related issues.
- Check the Tracks and Undercarriage
Regularly inspect the tracks, rollers, sprockets, and undercarriage for signs of wear and damage. Ensure that the tracks are properly tensioned and lubricated. Clean the undercarriage to prevent debris buildup, which can accelerate wear.
- Lubricate Moving Parts
Lubricating the moving parts of the Kobelco 905 LC-2 is crucial for reducing friction and preventing excessive wear. This includes lubricating the boom, arm, bucket, and all pivot points. Follow the manufacturer’s recommendations for the type of lubricant and intervals for application.
The Kobelco 905 LC-2 is a highly efficient and reliable excavator that is well-suited for a wide range of applications in construction, mining, and earth-moving projects. By performing regular maintenance and addressing common issues such as hydraulic problems, engine overheating, electrical failures, and undercarriage wear, operators can ensure that their machines continue to perform at their best.
Understanding the key features of the Kobelco 905 LC-2, as well as the proper troubleshooting and maintenance practices, will help maximize its productivity, extend its lifespan, and ultimately save on repair costs. Proper care and attention to detail will ensure that the 905 LC-2 continues to be a valuable asset on any job site.
