The replacement of the air filter for an excavator is a crucial part of its maintenance. Here are the correct steps for replacing the air filter :

  1. With the engine turned off, open the rear door of the cab and the filter cover.
  2. Remove and clean the rubber vacuum valve located under the air filter housing cover. Inspect the sealing edge for any wear and replace the valve if necessary.
  3. Disassemble the outer air filter element and inspect for any damage. Replace the filter element if damaged.

When replacing the air filter, it is important to note the following points:

  1. The outer filter element can be cleaned up to six times, but it must be replaced after that.
  2. The inner filter element is a disposable item and cannot be cleaned. It needs to be replaced directly.
  3. Do not use damaged sealing gaskets, filter media, or rubber seals on the filter element.
  4. Avoid using fake filter elements as they may have poor filtering performance and sealing, allowing dust to enter and damage the engine.
  5. Replace the inner filter element if the seal or filter media is damaged or deformed.
  6. Inspect the sealing area of the new filter element for any adhering dust or oil stains and clean them if necessary.
  7. When inserting the filter element, avoid expanding the rubber at the end. Ensure that the outer filter element is pushed straight and gently fit into the latch to avoid damaging the cover or filter housing.

In general, the lifespan of the excavator's air filter depends on the model and operating environment, but it typically needs to be replaced or cleaned every 200 to 500 hours. Therefore, it is recommended to replace or clean the excavator's air filter at least every 2000 hours or when the warning light comes on to ensure the normal operation and extend the service life of the excavator.

Please note that the replacement method for different types of excavator filters may vary. Therefore, it is advisable to refer to the excavator's operating manual or consult a professional for accurate replacement steps and precautions before proceeding with the replacement.
