How To Add Hydraulic Fluid To Excavator? Explained

Excavators are crucial heavy equipment used for various construction and excavation tasks. They are designed to handle the toughest digging jobs and are powered by hydraulic systems that operate the arm, bucket, and other components. To keep the excavator running smoothly and efficiently, it’s essential to maintain the hydraulic system properly. One important aspect of maintenance is adding hydraulic fluid when needed.

Locate the hydraulic tank and remove the cap to add hydraulic fluid to an excavator. Check the fluid level and add the appropriate type of hydraulic fluid if needed. Replace the cap and run the engine to circulate the fluid. Repeat until the desired level is reached.

Adding hydraulic fluid to an excavator can seem like a daunting task, especially for those who are new to operating heavy equipment. However, it is a straightforward process that can be easily accomplished by following simple steps. 

In this article, we will provide a detailed guide on how to add hydraulic fluid to an excavator, including the necessary tools and safety precautions. By the end of this article, you will clearly understand how to keep your excavator’s hydraulic system functioning at its best.

Identifying The Location Of The Hydraulic Tank

When adding hydraulic fluid to an excavator, one of the first steps is identifying the location of the hydraulic tank. The hydraulic tank is where the hydraulic fluid is stored and distributed throughout the hydraulic system. Adding or changing the hydraulic fluid without access to the hydraulic tank is impossible.

The location of the hydraulic tank can vary depending on the make and model of the excavator. However, it is usually located near the back of the excavator and can be identified by a cap on top of the tank. In some cases, the hydraulic tank may be hidden behind other components, so it’s important to refer to the excavator’s manual or seek guidance from a professional if unsure of the location.

Once you have located the hydraulic tank, it’s important to take note of any safety precautions or instructions provided by the manufacturer before proceeding with adding hydraulic fluid. This will help prevent any accidents or damage to the equipment during the process.

Choosing The Right Type Of Hydraulic Fluid

Choosing the right type of hydraulic fluid is crucial when adding fluid to an excavator’s hydraulic system. The wrong type of fluid can cause damage to the system, resulting in costly repairs and downtime.

To choose the correct hydraulic fluid for your excavator, it’s important to refer to the manufacturer’s manual. The manual will provide information on the type of hydraulic fluid recommended for the excavator and the quantity required. Using the recommended fluid type is essential, as using the wrong type can cause damage to seals and other components in the hydraulic system.

Different hydraulic fluids are available, including mineral-based, synthetic-based, and biodegradable. Each type has its own set of advantages and disadvantages. For example, mineral-based fluids are less expensive but have a shorter lifespan compared to synthetic-based fluids. Biodegradable fluids are environmentally friendly but can be more expensive.

It’s important to also check the viscosity grade of the hydraulic fluid, which refers to the fluid’s resistance to flow. The correct viscosity grade is critical for proper hydraulic system function. If unsure of which viscosity grade to use, refer to the manufacturer’s manual or seek guidance from a professional.

Precautions To Take Before Adding Hydraulic Fluid

Before adding hydraulic fluid to an excavator, it’s essential to take some necessary precautions to ensure safety and avoid damage to the equipment. The following are some of the precautions to take:

• Turn off the engine and let it cool down: Before adding hydraulic fluid, turn off the engine and let it cool down. This prevents hot hydraulic fluid from spilling out and causing injury.
• Wear protective gear: Wear protective gloves, safety glasses, and other protective gear to prevent contact with the fluid or other harmful materials.
• Clean the area around the hydraulic tank: Ensure that the area around the hydraulic tank is clean and free from debris. This prevents contaminants from entering the hydraulic system.
• Check the fluid level: Before adding hydraulic fluid, check the fluid level to ensure that it’s not already full. Overfilling the hydraulic tank can cause damage to the system.
• Use the recommended type of hydraulic fluid: Use only the recommended type of hydraulic fluid as specified in the manufacturer’s manual. Using the wrong type of fluid can cause damage to the hydraulic system.

Step-By-Step Guide To Adding Hydraulic Fluid

Adding hydraulic fluid to an excavator’s hydraulic system can be simple if you follow the correct steps. Here is a step-by-step guide to adding hydraulic fluid:

1. Locate the hydraulic tank: Locate the hydraulic tank by referring to the manufacturer’s manual or seeking guidance from a professional.
2. Remove the cap: Remove the cap on the hydraulic tank to access the fluid reservoir.
3. Check the fluid level: Check the fluid level to determine if it’s low and requires topping up.
4. Add the hydraulic fluid: Add the recommended type into the tank until it reaches the recommended level.
5. Replace the cap: Replace the cap on the hydraulic tank.
6. Start the engine: Let it run for a few minutes to circulate the new hydraulic fluid.
7. Check the fluid level again: Check the fluid level again and add hydraulic fluid if needed.
8. Secure the cap: Secure the cap on the hydraulic tank and ensure it’s tight.

Checking The Fluid Level And Ensuring Proper Circulation

Checking the fluid level and ensuring proper circulation are important steps in adding hydraulic fluid to an excavator. Here’s what you need to know:

After adding hydraulic fluid to the excavator’s hydraulic tank, it’s important to check the fluid level again to ensure it’s correct. Here’s how to check the fluid level:

• Turn off the engine and let it cool down.
• Remove the cap from the hydraulic tank and check the fluid level using the dipstick or sight glass.
• If the fluid level is too low, add hydraulic fluid until it reaches the recommended level.

Once the fluid level is correct, it’s essential to ensure proper circulation throughout the hydraulic system. Here’s how to ensure proper circulation:

• Start the engine and let it run for a few minutes.
• Engage the hydraulic system by operating the excavator’s arm, bucket, or other components.
• Check for any signs of leakage or unusual noises in the hydraulic system.
• Repeat checking the fluid level and ensuring proper circulation until there are no signs of issues.

Maintaining The Hydraulic System For Optimal Performance

Maintaining the hydraulic system is critical for ensuring the optimal performance of an excavator. Here are some tips for maintaining the hydraulic system:

• Regularly check the hydraulic fluid level and condition: Check the hydraulic fluid level and condition regularly and top up or change the fluid as needed.
• Keep the hydraulic system clean: Keep the hydraulic system clean by regularly removing any debris or dirt that may clog the system.
• Use the recommended hydraulic fluid: Use only the recommended type of hydraulic fluid as specified in the manufacturer’s manual.
• Replace hydraulic filters: Replace the hydraulic filters regularly to ensure the hydraulic fluid remains clean and free from contaminants.
• Address issues promptly: Address any issues with the hydraulic system promptly to prevent further damage and ensure optimal performance.

Follow the manufacturer’s maintenance schedule: Follow the manufacturer’s maintenance schedule to ensure that the hydraulic system is properly maintained and serviced.
