In this article, we explore the key features of the John Deere 855 Trackloader, common problems that operators may encounter, and the best practices for keeping it in peak condition.
What is the John Deere 855 Trackloader?
The John Deere 855 is a tracked loader designed for handling tough jobs in construction, mining, and forestry applications. It is built to provide superior performance in a range of terrains, including soft and uneven ground, where wheeled loaders might struggle. With its rubber tracks, it offers enhanced traction and stability, making it a popular choice for operators working on soft soil, muddy surfaces, or other challenging environments.
Key Features of the John Deere 855 Trackloader:
Common Issues with the John Deere 855 Trackloader
Despite its durability, the John Deere 855 Trackloader can experience several issues over time, particularly with its complex hydraulic and drivetrain systems. Below are some of the common problems that operators might face:
1. Hydraulic System Leaks
Hydraulic systems are crucial for the performance of trackloaders, and leaks can significantly reduce performance. Leaks may occur in the hydraulic hoses, pumps, or cylinders. Common symptoms of a hydraulic leak include:
Improper track tension is another issue that can affect the performance of the John Deere 855. If the tracks are too loose or too tight, it can cause excessive wear, poor traction, and potentially even damage to the undercarriage. Symptoms of improper track tension include:
Engine issues, such as poor starting or a lack of power, can arise due to several factors, including:
4. Electrical Failures
Electrical problems are common in older machinery and can manifest as faulty sensors, dead batteries, or malfunctioning starter motors. Symptoms include:
Understanding how to troubleshoot common problems is essential for maintaining the performance of the John Deere 855 Trackloader. Here are some steps to help diagnose and resolve common issues:
Step 1: Inspect the Hydraulic System
If you notice issues with the loader’s lifting capacity or fluid leaks, perform a visual inspection of the hydraulic hoses, cylinders, and pumps. Look for any visible signs of wear, cracks, or fluid leakage. Additionally, check the hydraulic fluid levels and clean the filter regularly to ensure smooth operation. If the problem persists, a hydraulic system pressure test may be required to pinpoint the issue.
Step 2: Check Track Tension
To check the tension on the tracks, raise the loader and inspect the slack in the track. The track tension should be within the manufacturer’s specifications. If the tracks are too loose, adjust the tension accordingly to ensure proper operation. Be sure to check for wear patterns on the tracks and sprockets as well, as this can indicate imbalances or damage.
Step 3: Perform Engine Maintenance
For engine-related issues, first ensure that the air filter is clean and free from debris. If the loader is hard to start, check the battery voltage and connections. Inspect the fuel system for clogs and clean the fuel injectors regularly. In case of a more serious issue, consider performing a compression test to check the engine’s overall health.
Step 4: Diagnose Electrical Failures
For electrical issues, start by checking the fuses and wiring. A blown fuse or corroded connector could be the culprit. If there’s still no power, consider testing the alternator, starter motor, and battery. Electrical failures can sometimes be resolved with minor repairs, but more extensive problems may require professional attention.
Preventive Maintenance Tips for the John Deere 855
To avoid major breakdowns and extend the life of the John Deere 855 Trackloader, regular maintenance is key. Here are some preventive maintenance tips:
1. Regular Fluid Checks
Hydraulic fluid and engine oil should be checked and changed according to the manufacturer's recommendations. Keeping the fluid levels at the proper level ensures that the loader operates smoothly without strain on the components.
2. Track and Undercarriage Inspections
The tracks and undercarriage are vital for the 855’s ability to perform in rough terrain. Regularly inspect the tracks for wear, cracks, and tension, and adjust as necessary. Keep the undercarriage free of dirt and debris, as this can cause damage to the tracks.
3. Clean the Radiator
To prevent overheating, clean the radiator regularly to ensure that air can flow freely. This is particularly important if the loader is used in dusty environments or hot conditions.
4. Follow the Manufacturer’s Maintenance Schedule
Adhering to the John Deere 855’s recommended maintenance schedule is the best way to avoid preventable problems. Regular servicing by a professional technician ensures that the loader is in top condition and can perform at its best.
Conclusion
The John Deere 855 Trackloader is a powerful and reliable piece of equipment that can handle a wide range of construction and earthmoving tasks. Like all machinery, it requires proper care and attention to maintain its performance and avoid common issues such as hydraulic leaks, track tension problems, and engine malfunctions.
By performing regular inspections and maintenance, operators can ensure that the 855 continues to deliver excellent results in tough conditions. When troubleshooting problems, always start with basic checks like fluid levels, wiring connections, and engine performance. With the right approach to maintenance and care, the John Deere 855 Trackloader will continue to serve operators efficiently for many years to come.
