Description

When you’re kicking up dust during harvest season or working in dry, gritty conditions, your tractor’s engine needs protection that can handle whatever Mother Nature throws at it. This complete oil bath air filter assembly uses the time-tested method of trapping dust and dirt in a pool of oil before it can damage your engine. It’s the same proven technology these Massey Ferguson tractors were built with, designed to keep working when paper filters would have given up long ago.

What You’re Getting

Complete assembly with oil bath cup, filter element, and all mounting hardware
Heavy-duty steel construction that stands up to vibration and harsh farm conditions
Washable, reusable filter element saves you money over time
Superior dirt-holding capacity compared to early paper filter designs
Authentic period-correct appearance that keeps your vintage tractor looking right

Built for Real Farm Work

This assembly fits your Massey Ferguson 135, 148, 230, 240, or 250—tractors that earned their reputation handling everything from cultivation and planting to hay production and general farm maintenance. These reliable workhorses were built when durability mattered more than fancy features, and they’re still earning their keep on farms today.

Made to Last

The oil bath design works by forcing dusty air to make a sharp turn over the oil surface, causing heavy particles to drop right into the oil where they stay trapped. Unlike paper filters that gradually restrict airflow as they load up with dirt, this system maintains consistent airflow—you just change the oil when it gets dirty.

Installation Notes

Mount the assembly securely using the provided hardware and fill the oil cup to the marked level with clean engine oil. Regular maintenance means draining the dirty oil, cleaning the filter element with solvent, and refilling with fresh oil every 50-100 hours depending on conditions. Keep an eye on that oil level—if it’s not cleaned regularly, those dust particles will turn your engine oil into liquid sandpaper.
