In this article, we’ll provide an in-depth look at the Case 850C, including its specifications, common issues, maintenance tips, and what to expect when purchasing a used model.
Introduction to the Case 850C
The Case 850C is part of Case's long-running line of C-Series dozers. It was designed for a variety of applications, from material handling and grading to site preparation and heavy lifting. This machine is particularly known for its efficiency, ability to handle challenging terrains, and excellent maneuverability on tight job sites. While newer models in the Case 850 line have evolved with enhanced technology, the 850C remains a popular choice due to its mechanical simplicity and proven performance.
The 850C was produced in the 1980s and 1990s, with a reputation for offering reliable power and efficient operation. As a used machine, it can be found at a fraction of the price of new dozers, making it an attractive option for many who are looking for cost-effective machinery that still delivers the performance they need.
Key Specifications of the Case 850C
The Case 850C is equipped with a range of specifications that make it a versatile machine for a wide range of heavy-duty tasks. Some of the standout features include:

• Engine: The Case 850C is powered by a Case 504D engine, a 4-cylinder, 4.4-liter diesel engine. It delivers approximately 80 horsepower, providing ample power for most construction tasks. The engine is known for its durability and ease of maintenance.
  
• Operating Weight: The operating weight of the 850C typically falls between 15,000 to 16,500 pounds, depending on the configuration. This makes it heavy enough for tough tasks but still light enough to remain mobile in smaller spaces.
  
• Hydraulic System: The dozer comes equipped with a closed-center hydraulic system, offering better efficiency and smoother operation for attachments and other hydraulic-powered tools.
  
• Transmission: The 850C features a hydrostatic transmission system, providing smooth and reliable power transfer. The hydrostatic drive also allows for easy speed adjustments, making it user-friendly in various terrain.
  
• Blade Types: The Case 850C can be equipped with various blade configurations, including a U-blade or Straight Blade, depending on the specific needs of the job site. The size of the blade is crucial for determining the machine's productivity in terms of material handling and grading.
  

Common Issues with the Case 850C
Despite its reputation for reliability, the Case 850C, like all heavy equipment, can experience issues over time, especially when it’s used heavily or not properly maintained. Below are some of the most common issues owners of the 850C might face:

• Hydraulic System Failures: Over time, the hydraulic system may experience leaks, reducing the efficiency of the loader’s attachments. The hydraulic pump or valves may need to be replaced or repaired.
  
• Engine Overheating: As with many older machines, engine cooling issues can arise, leading to overheating and potential engine damage. Regular maintenance of the cooling system, including the radiator, hoses, and coolant levels, is crucial to prevent this problem.
  
• Transmission Problems: The hydrostatic transmission can wear down over time, especially if the machine is used extensively for heavy-duty tasks. Symptoms of transmission issues include poor acceleration or loss of power to the tracks.
  
• Undercarriage Wear: The undercarriage, including the tracks, rollers, and sprockets, can wear out after prolonged use, particularly if the machine is used on rocky or abrasive surfaces. Regularly inspecting and maintaining the undercarriage is essential to keeping the 850C running smoothly.
  
• Electrical Issues: Wiring problems or faulty sensors are common in older machines. These can cause a variety of electrical malfunctions, from starting issues to more complex problems affecting the machine’s performance.
  

Tips for Maintaining the Case 850C
Proper maintenance is essential for ensuring the longevity and performance of the Case 850C. Here are some important tips:

• Regularly Inspect the Engine and Hydraulic System: Check the engine oil, coolant levels, and hydraulic fluid regularly to ensure everything is functioning as expected. Clean air filters can prevent engine overheating and improve fuel efficiency.
  
• Track and Undercarriage Maintenance: Regularly inspect the undercarriage for signs of wear, such as loose tracks or worn-out rollers. Addressing these issues early can help prevent more expensive repairs down the line.
  
• Transmission Fluid Changes: Transmission fluid should be changed according to the manufacturer's recommended intervals. This ensures smooth operation of the hydrostatic transmission system.
  
• Electrical System Check: Inspect the electrical system for any loose wires, corroded terminals, or faulty fuses. A well-maintained electrical system helps prevent unexpected breakdowns.
  
• Avoid Overloading: Avoid pushing the Case 850C beyond its capacity. Overloading the machine can cause excessive wear on both the engine and the hydraulic system.
  

What to Consider When Purchasing a Used Case 850C
If you’re in the market for a used Case 850C, there are several factors to keep in mind to ensure you get the best value for your investment:

• Check the Hours: The number of hours on the machine’s meter can give you a good indication of its usage. However, it’s not the only factor to consider—how well the machine has been maintained plays a huge role in its condition.
  
• Inspect for Leaks and Damage: Look for any visible leaks, especially in the hydraulic system. Check the condition of the tracks, blade, and undercarriage, as these parts can be expensive to repair or replace.
  
• Request Maintenance Records: Ask for any available maintenance records to get an idea of how the machine has been cared for. A well-maintained machine will typically run longer and require fewer repairs.
  
• Test the Machine: Before purchasing, it’s important to test the machine in action. Make sure the transmission operates smoothly, the engine runs without issue, and the hydraulic system functions as expected.
  

Conclusion
The Case 850C remains a dependable and efficient dozer, especially for those who are looking for a machine that can handle a variety of tasks without breaking the bank. With proper maintenance and care, the 850C can provide many more years of reliable service. Whether you're using it for construction, landscaping, or farming, this dozer’s solid performance makes it a great investment for those who need power and versatility on the job site. By staying on top of regular maintenance and being mindful of common issues, you can ensure your Case 850C runs smoothly for years to come.
