Master the Maintenance: A Comprehensive Guide on How to Change Hydraulic Fluid in New Holland Skid Steer

Maintaining your New Holland skid steer is crucial for optimal performance and longevity. One of the essential maintenance tasks is changing the hydraulic fluid. This guide will walk you through the process step-by-step, ensuring a smooth and efficient fluid change.

Why Change Hydraulic Fluid?

Hydraulic fluid plays a vital role in your skid steer‘s operation, transmitting power from the engine to the hydraulic system. Over time, this fluid degrades due to several factors:

• Contamination: Dust, dirt, and water can enter the system, contaminating the fluid and reducing its effectiveness.
• Heat: The hydraulic system generates heat during operation, leading to fluid breakdown and oxidation.
• Wear and Tear: As the hydraulic components wear down, microscopic metal particles can contaminate the fluid.

Dirty or degraded fluid can cause:

• Reduced Performance: Slower response times, decreased lifting capacity, and sluggish operation.
• Component Damage: Friction and wear caused by contaminated fluid can damage hydraulic pumps, motors, and other components.
• System Failure: Severe contamination can lead to complete system failure, resulting in costly repairs.

Required Tools and Materials

Before you begin, gather the necessary tools and materials:

• New Hydraulic Fluid: Refer to your New Holland skid steer’s operator manual for the recommended type and viscosity of hydraulic fluid.
• Drain Pan: A large capacity drain pan to collect the old fluid.
• Wrench Set: A set of wrenches, including a socket wrench for loosening and tightening bolts.
• Funnel: A funnel to pour the new hydraulic fluid into the reservoir.
• Gloves: Protective gloves to avoid skin contact with hydraulic fluid.
• Safety Glasses: Eye protection to prevent fluid splashes.
• Clean Rags: For wiping spills and cleaning surfaces.
• Optional: Hydraulic fluid pump (for easier filling).

Preparation and Safety

• Park the Skid Steer on a Level Surface: Ensure the skid steer is parked on a level surface and the parking brake is engaged.
• Shut Off the Engine and Disconnect Battery: Turn off the engine and disconnect the battery to prevent accidental operation.
• Allow the System to Cool: Let the hydraulic system cool down before proceeding. Hot fluid can cause burns.
• Wear Safety Gear: Always wear safety glasses, gloves, and appropriate clothing while working with hydraulic fluid.
• Locate the Hydraulic Reservoir: The hydraulic reservoir is typically located on the side or rear of the skid steer.

Draining the Old Fluid

1. Locate the Drain Plug: The drain plug is usually located at the bottom of the hydraulic reservoir.
2. Place the Drain Pan: Position the drain pan underneath the drain plug to collect the old fluid.
3. Loosen the Drain Plug: Use a wrench to loosen the drain plug.
4. Drain the Fluid: Allow the old hydraulic fluid to drain completely into the drain pan.
5. Tighten the Drain Plug: Once the fluid has drained, tighten the drain plug securely.

Filling the Reservoir

1. Locate the Fill Port: The fill port is typically located on the top of the hydraulic reservoir.
2. Remove the Cap: Carefully remove the fill cap.
3. Pour the New Fluid: Use a funnel to pour the new hydraulic fluid into the reservoir.
4. Check the Level: Refer to the markings on the reservoir to ensure the fluid level is within the specified range.
5. Replace the Cap: Securely replace the fill cap.

Running the System

1. Connect the Battery: Reconnect the battery.
2. Start the Engine: Start the engine and allow it to run for a few minutes.
3. Operate the Controls: Operate the skid steer‘s controls to circulate the new fluid throughout the system.
4. Check for Leaks: Inspect the hydraulic system for any leaks.
5. Top Off the Fluid: If necessary, top off the fluid level in the reservoir.

Post-Fluid Change Maintenance

• Dispose of Old Fluid Properly: Dispose of the old hydraulic fluid according to local regulations.
• Clean Up: Clean up any spills or drips with a clean rag.
• Record the Change: Keep a record of the date and fluid type used for future reference.

Concluding Thoughts: A Fresh Start for Your Skid Steer

Changing the hydraulic fluid in your New Holland skid steer is an essential maintenance task that ensures optimal performance, extends the life of your machine, and prevents costly repairs. Following these steps will enable you to complete the process safely and efficiently. Remember, regular maintenance is key to keeping your skid steer running smoothly and productively.

Questions We Hear a Lot

Q: How often should I change the hydraulic fluid in my New Holland skid steer?

A: Refer to your skid steer‘s operator manual for specific recommendations. Generally, it’s advisable to change the fluid every 250-500 hours of operation or annually, whichever comes first.

Q: Can I use any type of hydraulic fluid in my skid steer?

A: No, it’s crucial to use the specific type and viscosity of hydraulic fluid recommended by New Holland for your skid steer model. Using the wrong fluid can damage the hydraulic system.

Q: What should I do if I notice a leak in the hydraulic system?

A: If you notice a leak, immediately stop operating the skid steer. Contact a qualified mechanic to diagnose and repair the leak.

Q: Is it safe to change the hydraulic fluid myself?

A: While changing the hydraulic fluid is a relatively straightforward task, it’s important to have a good understanding of the process and safety precautions. If you’re unsure, it’s best to consult with a qualified mechanic.

Q: What are some signs that my hydraulic fluid needs to be changed?

A: Some signs that your hydraulic fluid needs to be changed include:

• The fluid is discolored or cloudy.
• The fluid has a burnt odor.
• The skid steer operates sluggishly or experiences reduced lifting capacity.
• The hydraulic system makes unusual noises.
• You notice leaks in the system.
