The Bobcat 863, a popular skid-steer loader, is known for its versatile and rugged performance across a variety of construction, landscaping, and material handling tasks. One of the essential components of the Bobcat 863 is the chain case, which is responsible for housing the drive chains and ensuring smooth operation of the machine. Proper lubrication of this component is crucial to maintaining its efficiency and longevity.
In this article, we’ll dive into the importance of selecting the right oil for the chain case, the role it plays in the overall performance of the machine, and the best practices for maintaining the Bobcat 863’s chain case to ensure optimal performance.
What is a Chain Case and Why is It Important?
The chain case in a skid-steer loader like the Bobcat 863 is a sealed housing that holds the drive chains. These chains transfer power from the engine to the wheels or tracks of the machine, enabling it to move and operate efficiently. The chain case is constantly subjected to pressure, friction, and heat, so proper lubrication is necessary to reduce wear and ensure smooth operation.
When lubricated correctly, the oil inside the chain case reduces friction between the chains and other internal components, prevents corrosion, and helps dissipate heat generated during operation. Without proper lubrication, the chain and components inside the chain case can wear out quickly, leading to costly repairs or replacements.
Choosing the Right Oil for the Bobcat 863 Chain Case
Selecting the right oil for the Bobcat 863’s chain case is critical to ensuring the longevity and smooth operation of the loader. The oil must provide adequate lubrication while withstanding the high pressures and temperatures the chain case experiences during operation.
1. Manufacturer Recommendations
The most reliable source of information regarding the appropriate oil type is the Bobcat 863’s operator’s manual. Manufacturers typically recommend specific oils that are formulated to work optimally with the loader’s chain case components. Following these recommendations helps avoid damage to the machine and ensures that warranty requirements are met.
For the Bobcat 863, the chain case typically requires a multi-viscosity oil designed for high-load applications. A commonly recommended oil type for Bobcat machines is Bobcat hydraulic oil or oils that meet Bobcat's specifications, such as ISO VG 46 hydraulic oil, although some models may require a different grade. The oil’s viscosity is important because it determines how well the oil can flow at different temperatures.
2. Oil Type: Synthetic vs. Conventional
There are two main types of oil available for the Bobcat 863 chain case: synthetic oil and conventional (mineral) oil.
Chain case oils often contain various additives designed to improve performance and protect against wear. Some of the most common additives include:
How to Change the Oil in the Bobcat 863 Chain Case
Changing the oil in the chain case of the Bobcat 863 is a relatively simple maintenance task that can help ensure the longevity of the loader’s drive components. Here’s a step-by-step guide to changing the oil in the chain case:
Step 1: Gather the Necessary Tools and Materials
You will need the following materials:
The chain case on the Bobcat 863 has a drain plug that allows you to drain the old oil. You’ll typically find this plug on the lower side of the chain case housing. Refer to the operator’s manual if you’re having trouble locating it.
Step 3: Drain the Old Oil
Place the container under the chain case and remove the drain plug. Allow the oil to drain completely into the container. Be sure to dispose of the old oil in accordance with local regulations.
Step 4: Inspect the Oil
Once the oil has drained, inspect it for signs of contamination or unusual debris. Dirty or contaminated oil may indicate an issue with the chain case, such as excessive wear or damage. If the oil is thick or sludgy, it may be time to clean or replace parts of the chain case.
Step 5: Refill with Fresh Oil
Using the funnel, refill the chain case with the recommended oil. Be sure not to overfill the chain case. Check the operator’s manual for the exact oil capacity. Once the oil is filled, replace the drain plug securely.
Step 6: Check for Leaks
Start the Bobcat 863 and run it briefly to ensure that the chain case is properly lubricated. After running the machine, check around the drain plug and the oil fill cap for any leaks. If you notice any leaks, re-tighten the fittings and recheck.
Maintaining the Chain Case for Longevity
To ensure that the Bobcat 863 continues to operate smoothly, regular maintenance is essential. Here are some additional tips for maintaining the chain case:
Maintaining the proper oil levels and choosing the right oil for the chain case on your Bobcat 863 is essential for ensuring the equipment's longevity and performance. Regular oil changes, proper maintenance, and the right oil choice can significantly extend the life of the chain case and reduce the risk of expensive repairs. By following the recommended guidelines and taking proactive care of your Bobcat 863, you can keep it running smoothly for years to come, ensuring maximum productivity on the job site.

2. Oil Type: Synthetic vs. Conventional
There are two main types of oil available for the Bobcat 863 chain case: synthetic oil and conventional (mineral) oil.
- Synthetic Oil:
Synthetic oils are man-made and offer superior performance in extreme conditions. They tend to perform better in high temperatures and can offer increased protection against wear and corrosion. Synthetic oils also maintain their viscosity better than conventional oils, providing more consistent lubrication over time. For operators working in harsh conditions or in very cold or very hot environments, synthetic oil is a great option.
- Conventional Oil:
Conventional oils, derived from natural petroleum, are often less expensive than synthetic oils but may require more frequent changes due to their lower performance in extreme temperatures. They are still a viable option for operators working in moderate climates and can provide adequate lubrication for general use.
Chain case oils often contain various additives designed to improve performance and protect against wear. Some of the most common additives include:
- Anti-wear agents: These chemicals form a protective layer on metal surfaces, reducing friction and minimizing wear over time.
- Corrosion inhibitors: Help prevent rust and corrosion from forming on internal components of the chain case, especially when the machine is exposed to moisture.
- Oxidation inhibitors: These help slow the breakdown of oil under high-temperature conditions, extending the oil's life and preventing sludge buildup.
- Anti-foam agents: Prevent the formation of foam in the oil, ensuring proper lubrication even under high-stress conditions.
