Bobcat 863G: A Comprehensive Overview and Troubleshooting Guide

[MikePhua]

The Bobcat 863G is a compact, versatile skid steer loader that has become a staple in construction, landscaping, and other demanding industries. Known for its robust build and ability to perform in tight spaces, the 863G is a go-to machine for operators needing high-performance capabilities in a smaller, more maneuverable package. However, like all equipment, it is prone to certain issues, particularly with its hydraulic and engine systems. This guide will explore common problems, provide solutions, and offer tips for maintaining the Bobcat 863G to ensure it performs at its best.
The Bobcat 863G: An Introduction
Manufactured by Bobcat Company, a leader in the compact equipment industry, the 863G was designed to provide powerful lifting, digging, and material handling capabilities while maintaining a compact form. The G-series models of Bobcat's skid steer range are known for their improved hydraulic systems, more refined control features, and better overall durability.
With a rated operating capacity of 2,400 pounds and a lifting height of over 11 feet, the Bobcat 863G is suited for a variety of applications, from construction and landscaping to snow removal and forestry. Its vertical lift path allows it to handle large loads in tight areas, making it highly efficient for jobs requiring precision and heavy lifting in confined spaces.
Common Problems with the Bobcat 863G
While the Bobcat 863G is a reliable machine, owners and operators often encounter specific issues that can affect its performance. Some of the most common problems include:
1. Hydraulic System Issues
The hydraulic system is at the heart of the Bobcat 863G’s performance, powering everything from the lifting arms to the attachments. Common issues include:

• Slow or Weak Hydraulic Performance: If the machine struggles to lift or operates at reduced power, it may be due to low hydraulic fluid levels, clogged filters, or a worn hydraulic pump.
  
• Hydraulic Leaks: Over time, seals, hoses, or fittings may degrade, leading to hydraulic fluid leakage. This can result in loss of power or, in severe cases, total system failure.
  

Solution:

• Ensure that the hydraulic fluid is at the proper level and check for leaks in the system.
  
• Replace any worn hoses or seals and clean or replace the hydraulic filters to improve system performance.
  
• If the hydraulic pump is worn, it may need to be replaced, especially if the machine is used frequently or in demanding conditions.
  

2. Engine Power Loss
Some operators report issues with the Bobcat 863G’s engine, including stalling or a noticeable loss of power during operation. This could be caused by several factors:

• Fuel System Problems: A clogged fuel filter or air filter can restrict fuel flow, leading to poor engine performance.
  
• Air Intake Issues: A dirty or blocked air filter can cause the engine to operate inefficiently, resulting in a lack of power.
  
• Fuel Quality: Low-quality or contaminated fuel can also impair engine performance.
  

Solution:

• Regularly replace the air and fuel filters to ensure proper airflow and fuel delivery.
  
• Use high-quality fuel and make sure the fuel tank is free from contaminants.
  
• Inspect the fuel system for leaks or issues and perform regular engine maintenance to prevent performance degradation.
  

3. Electrical Problems
Electrical issues can sometimes arise, leading to problems such as starting failure, malfunctioning lights, or inoperative controls. Common causes include:

• Battery Issues: A weak or dead battery can prevent the machine from starting or cause erratic electrical behavior.
  
• Corroded Terminals: Corrosion on battery terminals or other electrical connections can interfere with proper power flow.
  
• Faulty Wiring or Fuses: Broken or damaged wiring and blown fuses are common causes of electrical failures.
  

Solution:

• Check the battery charge and replace it if necessary. Clean the terminals and ensure a good connection.
  
• Inspect the electrical wiring and fuses for any signs of wear, corrosion, or damage.
  
• If the issue persists, consult a professional to test the electrical system and identify potential faults.
  

4. Track or Wheel Issues
For models of the Bobcat 863G that use tracks, track issues can arise over time, especially when operating in rough terrain or under heavy load. Common issues include:

• Track Slippage or Wear: If the tracks become loose or excessively worn, they can cause reduced traction and efficiency.
  
• Suspension Problems: Issues with the suspension system can lead to an uneven ride, further stressing the machine’s frame and leading to other mechanical problems.
  

Solution:

• Inspect the tracks regularly for wear and ensure that they are properly tensioned. Adjust or replace the tracks if needed.
  
• Check the suspension components for damage and lubricate them regularly to keep them operating smoothly.
  

Maintaining the Bobcat 863G for Longevity
To avoid common issues and ensure that your Bobcat 863G operates efficiently for years, regular maintenance is essential. Here are some key maintenance tasks:
1. Regular Fluid Checks and Changes
Hydraulic fluid, engine oil, and coolant should be checked regularly. Replace the oil and hydraulic fluid at recommended intervals, and always use the proper grades and types of fluid for the machine.
2. Filter Maintenance
Air filters and fuel filters should be cleaned or replaced as needed to maintain engine performance. Clogged filters restrict airflow or fuel supply, leading to decreased power and potential engine damage.
3. Track and Tire Maintenance
If your Bobcat 863G uses tires, ensure they are properly inflated and inspect them regularly for signs of wear or punctures. For track models, keep track tension and alignment in check to prevent unnecessary wear.
4. Cleaning the Machine
Debris, mud, and dust can accumulate in and around the Bobcat 863G during operation. Clean the machine regularly to prevent overheating, wear on parts, or debris interfering with moving components.
Conclusion
The Bobcat 863G is a powerful, versatile machine that offers exceptional performance in various industries. However, like any piece of machinery, it requires regular maintenance and care to ensure it continues operating at its best. By addressing common problems such as hydraulic issues, engine power loss, and electrical faults, operators can extend the lifespan of their 863G and avoid costly repairs. Regular servicing and adherence to manufacturer guidelines will help ensure that this robust skid steer loader remains a reliable workhorse for years to come.
Whether you're using the Bobcat 863G for heavy lifting, digging, or material handling, proper attention to detail and routine upkeep will maximize its effectiveness and minimize downtime.
