Air Cleaner Features
1. Check the Restriction
Check the restriction of the air cleaner with a Donaldson filter service indicator, service gauge, or a water manometer.
Replace the filter only when the restriction level has reached the maximum recommended by the engine or equipment manufacturer or on a regular service schedule.
2. Gently Remove the Old Filter
Switch the engine off. Handle the dirty filter gently, until it is clear of the air cleaner housing. Accidental bumping will shake dirt loose inside the filter housing.
3. Clean the Inside of the Housing
Always clean the inside of the housing. Dirt left in the air cleaner housing can potentially damage your engine.Use a clean, damp cloth to wipe every surface clean. Ensure that the outlet tube sealing area is clean and undamaged.
4. Visually Check the Inside Before Fitting the New Filter
Always clean the gasket sealing surface. An improper gasket seal is one of the most common causes of engine contamination. Make sure that all hardened dirt ridges are completely removed, both on the bottom and top of the air cleaner housing.
Check for uneven dirt patterns. Your old filter has valuable clues to dust leakage or gasket sealing problems. A pattern on the filter’s clean side is a sign that the old filter was not firmly sealed or that a dust leak exists. Identify the cause of that leak and rectify it before installing a new filter.
5. Inspect the New Filter Before Installation
Check the new filter but don’t install if it appears damaged. Check that the gasket is easily compressible and springs back promptly when finger pressure is released.
6. Install the New Filter
It is important to change the new supplied cover gasket with each filter service. Ensure that the filter is the correct size for the housing and install the filter, making sure the gasket seats evenly for a perfect seal. Without a proper seal, dirty air can by-pass the filter.
7. Ensure Air-tight Fit on All Connections and Ducts
Check that all clamps and flange joints are tight, as well as the air cleaner mounting bands. Attend to any leaks immediately to avoid dirt entering your engine directly. If the vehicle is fitted with air brakes, it is important to check the clean air supply hose which feeds the air brake compressor.
