Yanmar Tractor Air Filters: How to Clean, Check, and Replace

Yanmar Tractor Air Filters: The Basics

A properly maintained air filter is essential to maximizing your tractor’s performance and lifespan. It protects your tractor by removing harmful particulates before the air enters the engine. 

Though standard maintenance on a Yanmar tractor calls for checking your air filter every 100 hours, this can vary depending on your operating environment. For the most detailed information, always consult your operation manual.

Cleaning Your Tractor’s Air Filter

Fortunately, air filters are easy to access, clean, and replace on Yanmar tractors. Depending on your model, your tractor may have a single filter or both an inner and outer filter. Either way, the cleaning process is going to be very similar. Here’s what you need to know:

  • Start by removing the filter from your tractor. Take the single filter or outer filter and gently blow compressed air from inside the filter to the outside. Your air pressure should be no higher than 30 psi, as too much pressure can damage the filter.
  • If your outer filter has oil or carbon deposits, you can often still clean it. To do this, immerse the filter in a detergent solution for about 15 minutes. Then, carefully wash the filter several times in water. Finally, give it a rinse with clean water and allow it to dry completely.
  • Before you reinstall an air filter you’ve cleaned, always inspect for damage first. Simply shine a flashlight inside and visually identify any issues. Should you find damage, it’s best to replace the filter with a new one from your local Yanmar dealer.
  • If your tractor has an inner and outer air filter, the inner filter should be replaced whenever the outer filter is cleaned. The inner filter is disposable and not meant to be serviced. Using compressed air will cause severe damage.

Replacing Your Tractor’s Air Filter

Replacing the air filter in your Yanmar tractor is a quick and simple process. Here’s how to do it:

  1. Park your tractor on flat, stable ground and allow the engine to cool. 
  2. Open the tractor’s hood and remove the lid of the air filter canister.
  3. Remove the outer filter, leaving the inner filter in place. Wipe down the canister with a clean towel or rag.
  4. Remove the inner filter, replacing it with a clean new filter.
  5. Slide the outer filter back into the canister and secure the lid.
  6. Close the hood of your tractor and the job is complete.
