Evaluating the Case 850G Crawler Dozer: Performance and Common Issues

[MikePhua]

The Case 850G crawler dozer, introduced in the late 1990s, is a mid-sized machine designed for heavy-duty tasks such as land clearing, grading, and construction. Known for its durability and simplicity, the 850G has garnered a reputation for reliability. However, like any piece of machinery, it is not without its challenges. This article delves into the performance of the Case 850G, highlighting its strengths and addressing common issues reported by operators.
Performance and Design
The Case 850G is equipped with a hydrostatic transmission system, offering smooth and responsive control. Its power shift transmission allows for seamless gear changes, enhancing operational efficiency. The dozer's undercarriage is designed for durability, capable of withstanding the rigors of demanding job sites. Operators have noted the machine's balanced weight distribution and effective blade control, contributing to its overall performance.
Common Issues and Troubleshooting

1. Hydraulic Pump Failures
   A recurring issue with the 850G is hydraulic pump failure. Operators have reported instances where the hydraulic pump ceased to function, leading to a loss of power and functionality. Regular maintenance and timely replacement of worn components are essential to prevent such failures.
   
2. Electrical System Glitches
   Some operators have experienced electrical issues, particularly with the wiper system. These problems often stem from faulty wiring or malfunctioning switches. Thorough inspection of the electrical system and replacement of defective parts can resolve these issues.
   
3. Starting Difficulties
   Starting problems, such as the engine shutting off unexpectedly or failing to start, have been reported. These issues are often linked to faulty ignition switches or neutral safety switches. Regular inspection and maintenance of these components can mitigate such problems.
   
4. Transmission Overheating
   Instances of transmission overheating have been noted, particularly when the dozer is operated in high-load conditions. This can lead to reduced performance and potential damage. Ensuring proper fluid levels and regular maintenance of the transmission system can help prevent overheating.
   

Maintenance Recommendations
To ensure the longevity and optimal performance of the Case 850G crawler dozer, operators should adhere to the following maintenance practices:

• Regular Fluid Checks: Monitor and maintain appropriate levels of hydraulic and transmission fluids.
  
• Component Inspections: Conduct routine inspections of the hydraulic pump, electrical system, and ignition components.
  
• Timely Replacements: Replace worn or faulty parts promptly to prevent further damage.
  
• Operator Training: Ensure that operators are adequately trained to handle the dozer, reducing the risk of operator-induced issues.
  

Conclusion
The Case 850G crawler dozer remains a reliable and efficient machine for various heavy-duty tasks. While certain issues have been reported, adherence to regular maintenance and prompt attention to potential problems can significantly enhance the dozer's performance and lifespan. Operators who invest time in proper upkeep will find the 850G to be a valuable asset on the job site.
