How to Change Hydraulic Fluid The Right Way

Hydraulic fluid is a vital component of any hydraulic system. It helps to transmit power, lubricate components, and keep the system clean. Over time, however, hydraulic fluid can become contaminated or break down, leading to reduced performance and even system failure. That’s why it’s important to periodically change the hydraulic fluid in your system.

Changing hydraulic fluid is not a difficult task, but it does require some care and attention to detail. Here’s a step-by-step guide on how to change hydraulic fluid:

  1. Identify the type of hydraulic fluid you need. Different hydraulic systems require different types of fluid, so it’s important to use the correct type for your system. Consult your owner’s manual or the manufacturer’s website to determine the correct type of fluid for your system.
  2. Gather your tools and materials. You’ll need a drain pan, a filter wrench, a new filter, and the correct type of hydraulic fluid. You may also want to have a funnel and some clean rags on hand.
  3. Warm up the hydraulic system. If your hydraulic system has been in use, it’s a good idea to warm it up before changing the fluid. This will help to loosen any contaminants that may be present in the fluid, making it easier to drain.
  4. Drain the old fluid. Locate the drain plug on the bottom of the hydraulic reservoir. Using a drain pan to catch any spills, remove the plug and allow the old fluid to drain out. If your system has multiple reservoirs, repeat this process for each one.
  5. Replace the filter. The filter is responsible for removing contaminants from the hydraulic fluid as it circulates through the system. To replace it, first, locate the filter housing and remove the old filter using a filter wrench. Then, install the new filter, making sure to tighten it securely.
  6. Refill the system with new hydraulic fluid. Use a funnel to carefully pour the new hydraulic fluid into the reservoir, being careful not to overfill. If your system has multiple reservoirs, refill them all.
  7. Test the system. Once you’ve refilled the system with new fluid, start it up and run it for a few minutes to circulate the new fluid. Then, check for any leaks or other issues. If everything seems to be working properly, you’re all set!

Changing hydraulic fluid is an important part of maintaining your hydraulic system. By following these steps, you can help ensure that your system is operating at its best and avoid costly repairs down the road.


Safety precautions to follow when changing your hydraulic fluid

There are a few precautions you should keep in mind when changing hydraulic fluid:

  1. Use the correct type of fluid. Different hydraulic systems require different types of fluid, so it’s important to use the correct type for your system. Using the wrong type of fluid can damage your system and reduce its performance.
  2. Wear protective gear. Hydraulic fluid can be dirty and potentially hazardous, so it’s a good idea to wear gloves and other protective gear when handling it.
  3. Dispose of old fluid properly. Hydraulic fluid can be harmful to the environment, so it’s important to dispose of it properly. Check with your local authorities for guidelines on how to dispose of hydraulic fluid in your area.
  4. Follow the manufacturer’s recommendations. Your hydraulic system may have specific recommendations for changing the fluid, so be sure to follow them to ensure optimal performance.
  5. Be careful when handling heavy equipment. If you’re working on a hydraulic system that is part of a larger piece of equipment, be sure to follow all safety guidelines and use caution when handling the equipment.

By following these precautions, you can help ensure a safe and successful hydraulic fluid change.
