The Bobcat 863C HP-3 is a versatile skid steer loader designed for heavy-duty construction, landscaping, and agricultural tasks. While these machines are reliable, they can experience performance issues due to wear, misuse, or maintenance neglect. One of the recurring problems reported by users involves performance drop-offs and mechanical failures. In this article, we’ll explore the common issues associated with the Bobcat 863C HP-3, provide troubleshooting tips, and suggest practical solutions to help keep the machine running efficiently.
Overview of the Bobcat 863C HP-3
The Bobcat 863C HP-3 is a high-performance, radial-lift skid steer loader that was engineered to deliver outstanding lifting capacity, stability, and speed for various applications. Bobcat is a well-established name in the heavy equipment industry, known for its innovation in compact machinery. The 863C is equipped with a 68 horsepower engine and a 2,400-pound rated operating capacity. It's commonly used in construction sites, agricultural fields, and for landscaping projects.
Like other models in the Bobcat series, the 863C HP-3 offers superior maneuverability, impressive lifting capabilities, and a wide range of attachments that allow operators to tackle diverse jobs. However, with consistent use, operators might experience performance issues that can impact the machine’s efficiency.
Common Issues and Solutions
Below are some of the most common issues faced by Bobcat 863C HP-3 operators, along with recommended solutions.
1. Loss of Hydraulic Power
One of the most frequently reported issues with the Bobcat 863C HP-3 is a loss of hydraulic power. This can lead to slow operation of the lift arms, slower bucket movements, or the inability to use attachments efficiently. The problem may be caused by a few different factors:

• Low Hydraulic Fluid Levels: If the hydraulic fluid level is low, the hydraulic system won’t perform effectively. Check the fluid reservoir regularly and top off the hydraulic oil if necessary.
  
• Worn Hydraulic Pump or Motor: Over time, the hydraulic pump or motor may wear out. If this is the case, you might need to replace these components. Ensure that you use high-quality hydraulic oil to prevent excessive wear on the system.
  
• Clogged Hydraulic Filters: Hydraulic filters can become clogged with debris, reducing the system’s performance. Regularly inspect and replace the hydraulic filters as part of your maintenance routine.
  

Solution: Start by checking the hydraulic fluid levels and topping up as needed. If the problem persists, inspect the hydraulic pump, motor, and filters. Replace any components that appear damaged or worn out. Regular maintenance is critical to prevent this issue.
2. Engine Stalling or Overheating
Another issue often experienced by 863C HP-3 owners is engine stalling or overheating. This can be frustrating and may lead to downtime if not addressed quickly. Several factors can contribute to engine overheating or stalling:

• Dirty Air Filters: If the air filter is clogged with dust and debris, the engine can’t receive the necessary airflow to operate efficiently. This can lead to engine overheating and stalling.
  
• Cooling System Blockages: The radiator or cooling system might be clogged with dirt or debris, restricting airflow and causing the engine to overheat.
  
• Fuel System Problems: A failing fuel filter or clogged fuel lines can restrict the flow of fuel to the engine, causing stalling or poor performance.
  

Solution: First, inspect and replace the air filter if necessary. Clean the radiator and ensure that no blockages are present in the cooling system. Finally, check the fuel system for any issues with the filter or lines and address them as needed. Regular cleaning and maintenance of these components will help prevent overheating and stalling issues.
3. Uneven Ground Clearance and Poor Stability
While the Bobcat 863C HP-3 is designed to be stable and durable, some users report issues with uneven ground clearance or instability, especially when operating on sloped or uneven terrain. This can affect the loader’s performance and safety.

• Tire Wear: Worn-out tires can cause uneven ground clearance, making it difficult for the machine to maintain stability. Regularly check the tires for wear and replace them when necessary.
  
• Improper Weight Distribution: Uneven loading or improper attachment balancing can lead to instability. Ensure that loads are evenly distributed and that the center of gravity remains stable during operations.
  
• Suspension Issues: If the suspension system or shocks are damaged, it can affect the overall stability of the loader.
  

Solution: Regularly inspect the tires for wear and replace them if necessary. Make sure that attachments are balanced properly and the load is evenly distributed to maintain stability. Check the suspension components and replace any worn-out parts to ensure smooth and safe operation.
4. Electrical System Failures
Electrical issues are another common problem with the Bobcat 863C HP-3, particularly with the starter motor, alternator, or battery system. Common electrical failures include:

• Battery Drainage: The battery may lose charge or fail to start the engine due to age, poor connections, or an electrical drain from other components.
  
• Fuses and Relays: If the fuses or relays are blown, various electrical systems in the loader might malfunction, including lights, control panels, or the ignition system.
  

Solution: Begin by inspecting the battery, checking for corrosion on the terminals, and ensuring it is fully charged. If the battery is old, it may need to be replaced. Additionally, inspect the fuses and relays and replace any that are blown. Keep the electrical connections clean and tight to prevent further electrical issues.
5. Faulty or Sticking Joystick Controls
The Bobcat 863C HP-3 is equipped with joystick controls that manage various functions, such as lifting, tilting, and operating attachments. However, users sometimes report that these joysticks can become faulty or stick, making it difficult to control the loader accurately.

• Dirt or Debris in Joystick Mechanism: Over time, dust, dirt, and grime can accumulate in the joystick control mechanism, causing it to stick or become less responsive.
  
• Worn or Damaged Joystick Components: If the internal components of the joystick are worn or damaged, it could lead to erratic or non-responsive behavior.
  

Solution: Regularly clean the joystick controls and the surrounding area to remove any dirt or debris that may have accumulated. If the issue persists, inspect the internal components for wear and tear. Replacing worn-out parts will restore proper functionality to the joystick controls.
Conclusion
The Bobcat 863C HP-3 is a powerful and reliable skid steer loader, but like all machines, it requires regular maintenance and care to ensure optimal performance. Common issues such as hydraulic power loss, engine stalling, overheating, poor stability, electrical failures, and joystick malfunctions can be addressed with routine checks and appropriate solutions. By staying proactive with maintenance, ensuring proper lubrication, and replacing worn-out components, operators can keep their 863C HP-3 running efficiently and reduce the risk of costly downtime.
