How to replace the air filter of Loader Liugong 856?

Oct 30, 2025

As a supplier of the Loader Liugong 856, I understand the importance of maintaining this powerful piece of machinery. One crucial maintenance task is replacing the air filter. A clean air filter ensures that the engine receives clean air, which is essential for optimal performance, fuel efficiency, and longevity. In this blog post, I'll guide you through the process of replacing the air filter of the Loader Liugong 856.

Why Replace the Air Filter?

Before diving into the replacement process, let's briefly discuss why it's necessary to replace the air filter regularly. The air filter's primary function is to prevent dust, dirt, and other contaminants from entering the engine. Over time, the filter becomes clogged with these particles, which restricts the airflow to the engine. A restricted airflow can lead to a variety of problems, including reduced power, decreased fuel efficiency, and increased engine wear. By replacing the air filter at the recommended intervals, you can keep your Loader Liugong 856 running smoothly and efficiently.

Tools and Materials You'll Need

  • New air filter: Make sure you have the correct air filter for your Loader Liugong 856. You can find the appropriate filter by referring to the machine's manual or consulting with a Liugong dealer.
  • Socket wrench set: You'll need a socket wrench to remove the bolts that hold the air filter housing in place.
  • Safety glasses and gloves: Protect your eyes and hands from dust and debris during the replacement process.
  • Clean cloth: Use a clean cloth to wipe down the air filter housing and surrounding areas.

Step-by-Step Guide to Replacing the Air Filter

Step 1: Prepare the Machine

  • Park the Loader Liugong 856 on a level surface and engage the parking brake.
  • Turn off the engine and allow it to cool down completely. This will prevent you from getting burned and reduce the risk of fire.
  • Put on your safety glasses and gloves to protect yourself from dust and debris.

Step 2: Locate the Air Filter Housing

The air filter housing is typically located on the side of the engine compartment. It's a large, rectangular or cylindrical box with a lid that's held in place by bolts or clips. Refer to the machine's manual if you're having trouble finding the air filter housing.

Step 3: Remove the Air Filter Housing Lid

  • Use a socket wrench to remove the bolts or clips that hold the air filter housing lid in place.
  • Carefully lift the lid off the housing and set it aside. Be careful not to drop any debris into the housing.

Step 4: Remove the Old Air Filter

  • Reach into the air filter housing and grasp the old air filter.
  • Pull the old air filter out of the housing and inspect it for signs of damage or excessive dirt. If the filter is severely clogged or damaged, it's definitely time for a replacement.

Step 5: Clean the Air Filter Housing

  • Use a clean cloth to wipe down the inside of the air filter housing. Remove any dust, dirt, or debris that may have accumulated in the housing.
  • Pay special attention to the sealing surfaces of the housing to ensure a proper seal when the new filter is installed.

Step 6: Install the New Air Filter

  • Take the new air filter out of its packaging and make sure it's the correct size and type for your Loader Liugong 856.
  • Carefully insert the new air filter into the housing, making sure it's properly seated and aligned.
  • Double-check that the filter is installed correctly and that there are no gaps or spaces around the edges.

Step 7: Replace the Air Filter Housing Lid

  • Place the air filter housing lid back on the housing and align it with the bolt holes or clips.
  • Use a socket wrench to tighten the bolts or clips securely. Make sure the lid is firmly in place to prevent any air leaks.

Step 8: Test the Machine

  • Start the engine and let it run for a few minutes. Listen for any unusual noises or vibrations that may indicate a problem with the air filter installation.
  • Check for any signs of air leaks around the air filter housing. If you notice any leaks, stop the engine and tighten the bolts or clips further.

Additional Tips and Considerations

  • Follow the manufacturer's recommendations: Refer to the Loader Liugong 856's manual for the recommended air filter replacement intervals. These intervals may vary depending on the operating conditions and environment.
  • Inspect the air intake system: While you're replacing the air filter, take a moment to inspect the air intake system for any signs of damage or wear. Check the hoses, ducts, and connections for cracks, leaks, or loose fittings.
  • Keep a spare air filter on hand: It's a good idea to keep a spare air filter in your inventory in case you need to replace it unexpectedly. This can save you time and downtime if the air filter becomes clogged or damaged while you're on the job.

Replacing the air filter of your Loader Liugong 856 is a relatively simple maintenance task that can have a significant impact on the machine's performance and longevity.
