The Bobcat 863G, a popular model in the skid steer loader category, has proven to be a reliable workhorse on construction sites, farms, and landscaping projects. However, like all machines, it has its quirks, and users often encounter specific issues that need addressing as they accumulate hours of use. In this article, we explore two common concerns related to the Bobcat 863G with 2,500 hours of operation, discussing potential causes, troubleshooting steps, and maintenance tips to keep the machine running efficiently.
Understanding the Bobcat 863G
Before diving into the specific issues, it’s important to understand what makes the Bobcat 863G a versatile and capable machine. The 863G is a part of Bobcat’s G-series line of skid steer loaders, known for their durability, powerful hydraulics, and high lifting capacity. The 863G, equipped with a 75 horsepower engine and a rated operating capacity of 2,500 pounds, is often used for tasks such as material handling, digging, grading, and landscaping.
With 2,500 hours of usage, the machine is approaching the point where more intensive maintenance may be required, depending on its condition. At this stage, users may encounter issues related to general wear and tear or specific mechanical problems that need to be addressed.
Issue 1: Hydraulic System Concerns
One of the most common issues faced by Bobcat 863G owners as the machine ages is related to the hydraulic system. The 863G’s hydraulic system is crucial for powering the lift arms, auxiliary hydraulics, and other key components. Over time, as the machine racks up operating hours, users may notice a decrease in hydraulic performance or even complete failure if not properly maintained.
Some of the key symptoms that point to hydraulic issues include:
Another issue that Bobcat 863G owners often encounter is related to the electrical system. With 2,500 hours on the clock, wear on electrical components such as the alternator, battery, and starter motor can start to manifest.
Common symptoms of electrical problems include:
To extend the lifespan of the Bobcat 863G and minimize the risk of major breakdowns, it’s essential to keep up with routine maintenance. Here are some key maintenance tasks that should be performed regularly:
In a real-world example, a Bobcat 863G owner faced recurring hydraulic issues after the machine reached 2,500 operating hours. The operator initially noticed that the loader arms were slower than usual and that the auxiliary hydraulics were not functioning as expected. After performing a thorough inspection, it was discovered that the hydraulic filter had become clogged, restricting fluid flow. After replacing the filter and topping up the hydraulic fluid, the machine’s performance improved significantly. However, the operator also noted that air had trapped in the system, which caused some erratic operation. After bleeding the system, the machine was restored to full functionality.
Conclusion: Keep the 863G Running Strong
The Bobcat 863G is a reliable and powerful machine, but like all heavy equipment, it requires regular maintenance and prompt attention to any issues that arise. By addressing hydraulic and electrical problems early and performing routine maintenance, owners can extend the life of their 863G and avoid costly repairs. With the right care, the Bobcat 863G can continue to be a valuable asset for years to come, tackling jobs with the same reliability it had when first purchased.

The 863G’s hydraulic system is crucial for powering the lift arms, auxiliary hydraulics, and other key components. Over time, as the machine racks up operating hours, users may notice a decrease in hydraulic performance or even complete failure if not properly maintained.
Some of the key symptoms that point to hydraulic issues include:
- Slow or Unresponsive Lift Arms: If the loader arms are slow to raise or lower, it may indicate a problem with hydraulic fluid levels, a clogged filter, or air in the hydraulic lines.
- Leaking Hydraulic Fluid: Leaks around the hydraulic hoses, fittings, or cylinders can cause a drop in fluid levels, leading to reduced performance and potential damage to the hydraulic pump.
- Erratic Operation of Auxiliary Hydraulics: The auxiliary hydraulic system, responsible for powering attachments, may begin to function unpredictably, indicating a fault in the hydraulic control valve or pump.
- Check Fluid Levels: Always start by checking the hydraulic fluid levels. Low fluid is often the cause of sluggish or unresponsive operation. Ensure that the fluid is clean and at the correct level as per the Bobcat 863G manual.
- Inspect for Leaks: Inspect the hydraulic hoses, connections, and cylinders for visible leaks. Small leaks can quickly escalate into bigger problems, so timely repairs are necessary.
- Replace Filters: Over time, hydraulic filters can become clogged with debris, reducing fluid flow and performance. Regularly replace filters according to the manufacturer’s recommendations.
- Bleed the System: Air trapped in the hydraulic lines can cause erratic operation. If you suspect air is trapped in the system, follow the proper procedure to bleed the system.
- Check the Hydraulic Pump: If the hydraulic pump is showing signs of failure, it may need to be rebuilt or replaced. This can be a costly repair, so it’s essential to address issues early.
Another issue that Bobcat 863G owners often encounter is related to the electrical system. With 2,500 hours on the clock, wear on electrical components such as the alternator, battery, and starter motor can start to manifest.
Common symptoms of electrical problems include:
- Intermittent Starting Issues: If the machine struggles to start, especially on cold mornings, the issue could be related to the battery, starter motor, or the ignition system.
- Battery Drain: A battery that discharges too quickly or fails to hold a charge may indicate a faulty alternator or poor wiring connections.
- Blown Fuses or Circuit Breakers: If certain functions of the machine, such as lights or auxiliary hydraulics, stop working, it could be due to a blown fuse or tripped circuit breaker.
- Test the Battery: Use a voltmeter to test the battery’s voltage. A healthy battery should read between 12.6 to 12.8 volts when the machine is off. If the voltage is low, it may be time to replace the battery.
- Check the Alternator: The alternator should charge the battery when the machine is running. If the battery voltage is low even after the engine is running, the alternator may be faulty.
- Inspect Wiring and Connections: Look for loose or corroded connections, especially around the battery and starter motor. Poor connections can lead to intermittent electrical issues.
- Test the Starter Motor: If the engine turns over slowly or fails to start at all, the starter motor may be worn out. A technician can test the starter motor and replace it if necessary.
- Replace Fuses: If electrical functions stop working, check the fuses and circuit breakers. Replace any blown fuses with the correct amperage to restore functionality.
To extend the lifespan of the Bobcat 863G and minimize the risk of major breakdowns, it’s essential to keep up with routine maintenance. Here are some key maintenance tasks that should be performed regularly:
- Change Engine Oil and Filters: Regular oil changes help keep the engine running smoothly and prevent premature wear. Follow the recommended intervals in the owner’s manual.
- Grease the Loader Arms: The loader arms and other pivot points should be greased regularly to prevent friction and wear. This helps extend the lifespan of the hydraulic system and maintains smooth operation.
- Clean the Air Filters: Dirty air filters can reduce engine efficiency and lead to increased fuel consumption. Clean or replace the air filters as needed.
- Inspect Tires or Tracks: Depending on whether your 863G is equipped with tires or tracks, regular inspection for wear and tear is essential. Proper tire pressure or track tension ensures optimal performance.
- Check for Loose Bolts: Over time, bolts and fasteners can loosen due to vibration. Check and tighten any loose bolts to avoid structural issues.
