Introduction
Hydraulic oil is a vital part of any heavy equipment, and the CAT 955L loader is no exception. Whether you're using it for digging, lifting, or grading, ensuring the hydraulic system is properly lubricated with the right hydraulic oil is crucial for its performance and longevity. Improper oil choice or insufficient oil can lead to inefficiency, increased wear and tear, and even major system failures. So, what type of hydraulic oil should you use in your CAT 955L, and how much do you need to ensure optimal performance?
This article will explore the best hydraulic oil options for the CAT 955L, how to determine the right amount, and provide tips for maintenance to keep your hydraulic system running smoothly.
Understanding the Role of Hydraulic Oil
Hydraulic oil acts as both a lubricant and a power transfer medium in hydraulic systems. It not only helps power the hydraulic components—such as the cylinders and pumps—but also plays a role in cooling, rust prevention, and keeping the system free from contaminants. Therefore, using the right oil is key to maintaining the integrity of the hydraulic system.
The hydraulic system in the CAT 955L, like other construction machinery, requires oil that can withstand high pressure and variable temperatures while providing excellent lubrication. Using the wrong oil, or not having enough oil in the system, can cause hydraulic failure, decreased efficiency, and potential damage to the pumps and seals.
What Kind of Hydraulic Oil Should You Use for the CAT 955L?
When selecting hydraulic oil for the CAT 955L, there are several factors to consider. The primary considerations include oil viscosity, additives, and manufacturer specifications.
1. Viscosity:
Viscosity is a measure of how thick or thin the oil is, and it directly impacts how well the oil can flow through the hydraulic system. The CAT 955L operates under various temperature conditions, so you need to choose a hydraulic oil with the right viscosity grade to ensure proper fluid flow.
For the CAT 955L, the recommended viscosity grade typically falls in the range of ISO 46 to ISO 68, depending on the operating temperature. In colder environments, a lower viscosity oil such as ISO 46 is preferable because it flows more easily in lower temperatures. In hotter climates or more demanding applications, ISO 68 might be more appropriate for its thicker consistency, which can help prevent oil breakdown under higher operating temperatures.
2. Oil Additives:
Hydraulic oils often come with a variety of additives designed to improve performance. These additives might include anti-wear agents, corrosion inhibitors, and foam suppressants. For the CAT 955L, it's essential to use an oil that includes anti-wear additives, especially because hydraulic systems are subject to high pressure and constant wear.
Additionally, consider oils with additives that help with oxidation resistance, as these can protect your hydraulic components from breakdown and help extend oil life. Always check the manufacturer’s recommendations for specific additive requirements, as using an oil without the proper additives can lead to premature wear and failure.
3. Manufacturer Recommendations:
CAT recommends using oils that meet or exceed the specifications outlined in the machine’s service manual. For the 955L, Caterpillar often suggests using oils like the CAT HYDO 10, which is a highly recommended hydraulic oil for Caterpillar machines. However, there are many reputable brands that meet these specifications, including Mobil, Shell, and Chevron. Always check the label to ensure compatibility with the CAT 955L's hydraulic system.
How Much Hydraulic Oil Does the CAT 955L Need?
The amount of hydraulic oil your CAT 955L loader requires depends on several factors, including the size of the hydraulic system, the presence of any leaks, and whether you're performing a complete oil change or just a top-up.
1. Oil Capacity:
The hydraulic oil capacity of the CAT 955L varies depending on the specific configuration of the machine, but on average, it is around 60 to 70 liters (approximately 15 to 18 gallons). This includes the oil needed for the main hydraulic reservoir and any additional lines or components that are part of the system.
If you are performing a full hydraulic oil change, it’s important to consult the owner's manual for your specific machine model to determine the exact oil capacity. Never overfill the hydraulic reservoir, as this can cause pressure issues and damage to the hydraulic pump.
2. Checking and Maintaining Oil Levels:
Regularly checking and maintaining the proper oil level is crucial to ensure the efficient operation of the hydraulic system. Here’s how to check and maintain oil levels:
Low or contaminated hydraulic oil can lead to reduced efficiency and potential failure of your hydraulic system. Some signs that your oil levels or quality may be an issue include:
Changing hydraulic oil is an essential maintenance task that can prolong the life of your machine and keep it running smoothly. Here’s a step-by-step guide to changing hydraulic oil in the CAT 955L:
Maintaining the hydraulic oil in your CAT 955L is a critical task to ensure optimal performance and longevity of your equipment. Choosing the right hydraulic oil, whether it’s ISO 46 or ISO 68, with the proper additives, is essential for smooth operation. Regularly checking the oil levels and changing the oil at the recommended intervals can save you time and money by preventing damage to the hydraulic system.
By following the manufacturer’s guidelines and using high-quality hydraulic oil, you’ll keep your CAT 955L loader performing efficiently and effectively, making it a valuable asset for years to come.

2. Checking and Maintaining Oil Levels:
Regularly checking and maintaining the proper oil level is crucial to ensure the efficient operation of the hydraulic system. Here’s how to check and maintain oil levels:
- Park the machine on level ground: Always check hydraulic oil levels when the machine is on level ground to ensure an accurate reading.
- Check the oil level regularly: Use the hydraulic oil dipstick or sight gauge to monitor the oil level. If the oil level is low, top it up with the recommended hydraulic fluid. It's always a good idea to keep spare oil on hand for topping up.
- Monitor for leaks: If you find that you are consistently topping up the hydraulic oil, there might be a leak in the system. Check the hoses, cylinders, and seals for any signs of leakage. Regular maintenance and repairs will help prevent further oil loss and avoid system failure.
Low or contaminated hydraulic oil can lead to reduced efficiency and potential failure of your hydraulic system. Some signs that your oil levels or quality may be an issue include:
- Erratic or sluggish movement of the hydraulics: If the loader’s arms, bucket, or other hydraulic components are moving slowly or unevenly, this could be due to insufficient or contaminated oil.
- Unusual noises: Grinding, whining, or excessive noise from the hydraulic pump or motor may indicate that the oil is too low or contains air, moisture, or debris.
- Increased operating temperatures: Hydraulic oil that is old or contaminated may lose its ability to dissipate heat properly, causing higher-than-normal operating temperatures in the hydraulic system.
Changing hydraulic oil is an essential maintenance task that can prolong the life of your machine and keep it running smoothly. Here’s a step-by-step guide to changing hydraulic oil in the CAT 955L:
- Drain the old oil: First, position the loader on a level surface and place a drain pan underneath the hydraulic reservoir. Remove the drain plug and let the old oil drain completely. Ensure the machine is off and cool before starting the process.
- Replace the filter: While the oil is draining, it’s a good idea to replace the hydraulic oil filter. This helps ensure that the new oil remains clean and free from contaminants.
- Refill with the correct oil: Once the old oil has been drained and the filter replaced, refill the hydraulic system with the recommended hydraulic oil, using the correct amount as specified in the owner’s manual.
- Check for leaks: After filling, inspect the system for any leaks, particularly around the filter and drain plug.
- Test the system: Start the loader and run the hydraulic system through its full range of motion. Check for any unusual noises or issues in the hydraulic operation.
Maintaining the hydraulic oil in your CAT 955L is a critical task to ensure optimal performance and longevity of your equipment. Choosing the right hydraulic oil, whether it’s ISO 46 or ISO 68, with the proper additives, is essential for smooth operation.
