Description
When you’re working on older tractors—whether it’s that reliable Massey Ferguson 135 you bought years ago or a restored Case 530—keeping the air intake system sealed up tight is what keeps those engines running strong. If dust particles enter the engine and mix with oil, they work like sandpaper to wear out components. This pre-cleaner cover is the lid that goes on top of your oil bath air cleaner bowl, sealing everything up and making sure the system works like it should.
What You’re Getting
- 7-inch diameter cover that fits standard oil bath pre-cleaner systems
- Includes brass mounting nut that won’t rust or seize up over time
- Proper fit ensures good sealing to prevent unfiltered air from bypassing the system
- Direct replacement for worn or missing covers across multiple vintage tractor brands
Built for Real Farm Work
These covers fit legendary machines that served as the backbone of agricultural operations for decades, handling everything from field cultivation and planting to harvesting and material handling, particularly popular for mixed farming operations where tractors were designed for reliability in dusty conditions. Whether you’re running a Cockshutt 570 for hay work, using an International for loader duties, or keeping that old Allis Chalmers D17 earning its keep around the farm, this cover keeps your oil bath air cleaner doing its job.
Made to Last
These covers are built to handle the constant temperature changes, vibration, and exposure that farm equipment faces. The included brass nut won’t corrode like steel hardware can, so you’ll actually be able to remove it for service years down the road. The metal construction stands up to the heat and chemicals that old tractors generate.
Installation Notes
This cover simply threads onto your existing pre-cleaner bowl with the brass nut. Make sure all connections are tight to prevent air leaks and maintain optimal filtration efficiency. If your old cover has been missing for a while, check that the bowl threads are clean and not damaged before installing the new one.
