Less Than One Minute Maintenance: Change Out an Excavator Cab Filter

Written by Luis Montes Updated On  October 9, 2023

An arrow points to the location of the cab air filter on a Cat 314E mini excavator

Changing a cabin air filter will take 1 minute, more or less.

You probably won’t even need tools to do it.

In this case, we’ll replace the filter on a Cat 314E Excavator. The air filter is behind an exterior panel on the left-hand side. Other makes and models have the cab filter behind the seat (Caterpillar 320, Bobcat E85, Kubota KX080) or underneath the floor mat (Komatsu PC210LC-11, Hitachi ZX210LC-6, Volvo EC220E).

There’s a video version available on the Tekamo HD YouTube channel:

How To Change the Cabin Filter

Heavy-duty mechanic removes the cab air filter from an excavator

Pull and lift the worn filter to remove it.

Notice the filter has a clean side and a dirty side. Keep it in mind when installing the new filter.

Compare the new filter against the old one to ensure you have the model.

Heavy-duty mechanic installs a new cabin air filter on a Cat 314E excavator

To install the new external filter, lock the bottom tabs in the compartment, and because it’s friction fit, just push the filter in.

Close the panel, and you’re good to go.

When Should You Change the Cabin Air Filter

Frequency varies depending on the equipment manufacturer: every 50, 250, 500, or 1000 hours. Check your operator’s manual.

Also, pay attention to these signs indicating the cab filter is clogged:

  • Reduced airflow.
  • Dust or debris buildup.
  • Odors from exhaust fumes or other contaminants.
  • Allergy or Respiratory Symptoms.

Unlike changing the cabin air filter, most maintenance tasks on the John Deere 35G require heavy-duty tools. At Fortis HD, you’ll find top-tier HD tools to keep your heavy equipment in peak condition. Check them out.
