The Bobcat 870 is a versatile and reliable skid steer loader known for its ability to perform a wide range of tasks in construction, agriculture, and landscaping. Like many heavy equipment machines, it is equipped with an air conditioning (A/C) system to ensure operator comfort during long hours of operation, especially in harsh working conditions. One of the most important aspects of maintaining the A/C system is ensuring that it is properly charged with the right amount of refrigerant. In this article, we will take a detailed look at the refrigerant capacity of the Bobcat 870, its importance, and how to maintain the A/C system for optimal performance.
What is Refrigerant and Why Is It Important?
Refrigerant is a substance used in air conditioning systems to absorb and release heat. In the case of the Bobcat 870, the refrigerant circulates through the system to remove heat from the cabin, keeping the operator cool and comfortable. The refrigerant works by passing through an evaporator and condenser, where it changes from a gas to a liquid and back again, effectively removing heat from the air.
Without the proper amount of refrigerant, the A/C system will not function efficiently, leading to poor cooling performance, increased wear on the compressor, and potential system failure. This makes understanding and maintaining the correct refrigerant level a crucial part of keeping the Bobcat 870 operating smoothly.
Refrigerant Capacity of the Bobcat 870
The refrigerant capacity of an A/C system refers to the amount of refrigerant required to fill the system to its optimal operating level. For the Bobcat 870, the recommended refrigerant capacity is typically specified in ounces or pounds. For this particular machine, the refrigerant capacity is usually around 2.6 pounds (approximately 41.6 ounces) of R-134A refrigerant.
Signs of Insufficient Refrigerant
If the A/C system in your Bobcat 870 is not cooling as effectively as it should, it may be due to a low refrigerant charge. Some common signs that indicate a refrigerant problem include:
How to Check and Recharge the Refrigerant on the Bobcat 870
Before attempting to recharge the refrigerant in your Bobcat 870, ensure that you have the necessary tools and knowledge. Here’s a step-by-step guide on how to check and recharge the A/C system:
1. Check the A/C System Pressure
The first step is to use an A/C manifold gauge to check the pressure of the refrigerant in the system. The gauge will provide a reading of the high and low pressure sides of the A/C system. Compare these readings to the recommended pressure ranges for R-134A refrigerant, which are usually provided in the operator’s manual.
2. Locate the Service Ports
The Bobcat 870’s A/C system will have two service ports—one on the low-pressure side and one on the high-pressure side. The low-pressure side is typically the one used for adding refrigerant.
3. Attach the Refrigerant Canister
Using the appropriate hose and adapter, connect the refrigerant canister to the low-pressure service port. Be sure to use R-134A refrigerant for this process, as it is the recommended refrigerant for the Bobcat 870.
4. Add Refrigerant
Start the engine and turn on the A/C system to the maximum cooling setting. Begin adding the refrigerant slowly into the system, while monitoring the pressure readings on the manifold gauge. Do not overfill the system, as this can cause damage to the compressor and other components.
It is important to follow the recommended refrigerant capacity (2.6 pounds or 41.6 ounces) to ensure the A/C system works optimally. Overcharging or undercharging can lead to performance issues.
5. Check for Leaks
After recharging the refrigerant, inspect the system for any signs of leaks. You can use a leak detection dye or a simple soap solution on the connections to check for leaks. If a leak is found, it must be repaired before recharging the system again.
6. Test the A/C System
Once the refrigerant is added and the system is leak-free, test the A/C to ensure it is cooling effectively. Check that the compressor is running smoothly and that the system is maintaining proper pressure.
Maintaining the A/C System for Longevity
To ensure the longevity and efficiency of the Bobcat 870’s A/C system, regular maintenance is essential. Here are a few tips to keep the system in top condition:
Maintaining the proper refrigerant level in the Bobcat 870’s A/C system is crucial for ensuring the comfort and productivity of the operator. By understanding the recommended refrigerant capacity, recognizing the signs of low refrigerant, and following proper maintenance procedures, you can extend the life of your A/C system and avoid costly repairs. Regularly checking and recharging the refrigerant, along with performing routine inspections, will keep your Bobcat 870 performing at its best in all conditions.

If the A/C system in your Bobcat 870 is not cooling as effectively as it should, it may be due to a low refrigerant charge. Some common signs that indicate a refrigerant problem include:
- Weak Cooling Performance: If the air coming from the vents is not as cold as it should be, it may indicate that the refrigerant level is low.
- Longer Cooling Time: It takes longer than usual for the cabin to cool down, or it doesn’t cool down at all.
- Compressor Clutch Cycling: The compressor clutch may cycle on and off rapidly, which is a sign that the system is struggling to maintain the proper pressure.
- Frost Build-Up: Excessive frost or ice may form on the A/C lines or evaporator coils, indicating that the refrigerant is not circulating properly.
