Description
When you’re working in dusty conditions—whether it’s harvest season, cultivating dry ground, or running hay equipment—your Ford’s engine needs proper protection. This 7-inch oil bath air cleaner assembly is the same type that came on your 4000, 4100, or 5000 series tractor from the factory, designed to handle the kind of dust that would choke a paper filter.
What You’re Getting
- Complete 7-inch diameter assembly that mounts directly to your existing air intake
- Oil bath design that captures dust particles in oil instead of clogging like paper filters
- Consistent airflow even in extremely dusty conditions—just change the oil when it gets dirty
- Heavy-duty construction built to handle the vibration and temperature swings of farm work
- Direct replacement for original Ford equipment—no modifications needed
Built for Real Farm Work
While modern tractors use paper filters, oil bath cleaners remain incredibly effective for their intended purpose. As dusty air enters, it’s forced to make a sharp turn over the oil surface, causing heavier particles to drop into the oil. This assembly fits Ford 4000 and 5000 series tractors built from 1965-1974, plus the 4100 models from 1975-1981—tractors that were built when equipment was expected to work in the dustiest conditions.
Made to Last
Your Ford was built tough, and this air cleaner matches that durability. The housing is constructed to handle years of field use, temperature changes, and the constant vibration that comes with tractor work. Unlike paper filters that clog and restrict airflow, oil bath cleaners maintain consistent airflow—critical for keeping your engine running at peak performance.
Installation Notes
Installation is straightforward but attention to detail matters. Clean the air intake pipe thoroughly before mounting the new assembly. Fill the oil cup to the marked level with the same grade oil used in your engine – overfilling reduces effectiveness and can cause oil to be sucked into the engine.
