The John Deere 820-2010 Crawler Loader, a machine from the early 1960s, remains an iconic piece of heavy equipment for its robust design and reliable performance. This crawler loader, equipped with a diesel engine, was used in a variety of construction, farming, and industrial applications. However, as with any piece of older machinery, maintenance and repairs can become challenging, especially when dealing with issues like track removal. In this article, we will explore the typical issues faced when removing tracks from this vintage model and offer practical solutions for overcoming these challenges.
History and Development of the John Deere 820-2010 Crawler Loader
Introduced in the 1960s, the John Deere 820-2010 Crawler Loader was designed for a range of tasks that required mobility, durability, and lifting power. It was part of Deere's push into the crawler loader market, where it would compete with similar models from companies like Caterpillar and Case. The 820-2010 featured a heavy-duty construction, powered by a 4-cylinder diesel engine that delivered impressive torque for its time.
With its hydraulic system and versatile track design, the 820-2010 became a popular choice for operators working in construction, mining, and even road-building. The machine’s ability to efficiently transport materials, excavate, and load made it a staple in heavy equipment fleets across the country. Over time, the John Deere 820-2010 became a reliable, albeit outdated, piece of equipment.
Despite the advancements in machinery technology since the 1960s, the 820-2010 crawler loader remains valued for its reliability and solid engineering. The challenges of maintaining and repairing such vintage machines, however, often arise due to a lack of readily available parts and the technical know-how needed for specific tasks like track removal.
Challenges in Removing Tracks from the John Deere 820-2010 Crawler Loader
Track removal is one of the more intricate tasks when dealing with a crawler loader. For the John Deere 820-2010, the process can be particularly difficult due to the age of the machine and its design. Some common issues faced by operators trying to remove the tracks include:

1. Rust and Corrosion: Over the years, exposure to harsh working environments can lead to severe rust and corrosion of the track components. This can cause the pins and bushings, which are essential for removing and replacing the tracks, to seize up. Rusted parts make it difficult to loosen and remove bolts, and can also lead to the breakage of essential components during the removal process.
   
2. Misalignment of Track Components: If the machine has been used extensively or improperly maintained, the track components (such as the sprockets, idlers, and rollers) may become misaligned. Misalignment can complicate the removal process, making it harder to disconnect the tracks and separate them from the machine.
   
3. Worn Track Components: Worn or damaged tracks, especially on a machine that has seen many years of use, can make removal difficult. If the tracks are excessively worn, they may no longer fit properly, and the tension in the track can be inconsistent, leading to further challenges when trying to remove them.
   
4. Aging Hydraulic Systems: The John Deere 820-2010 relies on its hydraulic system to loosen certain track components and tension. Over time, the hydraulic system may lose efficiency or develop leaks, which can affect the removal process.
   
5. Lack of Proper Tools: Specialized tools are required to remove the tracks on the John Deere 820-2010, such as a track jack, track pins, and specialized wrenches. Without the proper equipment, the job becomes much harder and more time-consuming. Operators who lack access to these tools may find themselves stuck in the middle of the task, especially if the tracks are particularly stubborn.
   

Steps to Overcome Track Removal Issues
While track removal on the John Deere 820-2010 can be tricky, there are several steps that operators can take to simplify the process and ensure that the job is done safely and effectively.

1. Prepare the Machine Properly: Before beginning track removal, ensure the machine is parked on level ground and the parking brake is engaged. Position the crawler loader in a way that allows for easy access to the track area. If the machine is in poor condition or the tracks are heavily rusted, you may need to use an engine hoist or jack to raise the loader slightly to relieve tension on the tracks.
   
2. Use Penetrating Oil: For rusted and corroded parts, penetrating oil such as WD-40 or PB Blaster can help loosen stubborn bolts and parts. Apply the oil to all critical areas, such as the track pins, bolts, and rollers. Allow the oil to sit for several hours, or even overnight, to ensure it has time to break through the rust and corrosion.
   
3. Inspect and Replace Worn Parts: Before attempting track removal, take the time to inspect the condition of the track components. If there is significant wear on the sprockets, rollers, or track pads, it may be worth replacing these components before attempting removal. Additionally, check for any misalignment that could hinder the process.
   
4. Loosen Track Tension: Use a track tensioning tool to relieve the tension in the track. This step is crucial for allowing the track to be removed without unnecessary resistance. If the track is too tight, it may be difficult or even dangerous to attempt removal. Once the tension is released, the track should slide off more easily.
   
5. Use the Right Tools: A track jack, track pin removal tool, and appropriate wrenches are essential for this process. Ensure that all tools are in good working condition before starting the removal. If you are missing any specific tools, consider renting or purchasing them from a reputable dealer.
   
6. Work in Phases: Track removal is a methodical process. Work slowly, and remove one component at a time. Starting with the track pins, carefully loosen and remove each pin. Once the pins are removed, the track should come off more easily.
   

Preventing Future Track Removal Issues
After successfully removing the tracks, it’s important to take steps to prevent future issues from arising. Here are a few recommendations:

1. Regular Maintenance: Keep the hydraulic and track systems well-maintained to prevent premature wear or damage. Regular inspections will ensure that any potential issues are addressed early on, saving time and money in the long run.
   
2. Lubrication: Regularly lubricate the track components, including the pins, rollers, and sprockets, to prevent rust and corrosion from building up. This will make future track removal easier and extend the lifespan of the machine.
   
3. Protective Coatings: Consider applying a protective coating to the track components to prevent rust and corrosion, especially if the equipment is used in harsh environments.
   

Conclusion: The John Deere 820-2010 Crawler Loader and Track Maintenance
The John Deere 820-2010 crawler loader, while an older machine, continues to be an essential piece of equipment in many industries. Its durability, combined with proper maintenance, ensures that it can serve its purpose for many years. Track removal, though challenging, can be tackled with the right tools, techniques, and a little patience. By following proper procedures and maintaining the loader regularly, operators can avoid the frustration of track removal issues and extend the overall lifespan of this classic piece of machinery.
