Description
When you’re doing routine maintenance or adding oil to top off between changes, you need an oil filler cap that seals tight and stays put. A worn or cracked cap lets in dust and moisture while letting out oil vapors, which can contaminate your engine oil and create messy spills around your tractor. This replacement cap keeps everything sealed up proper so you can focus on the work at hand.
What You’re Getting
- Secure threaded design that won’t vibrate loose during field work
- Tight seal prevents dust and moisture from getting into your engine oil
- Durable construction handles the temperature swings and rough conditions on the farm
- Direct replacement for your original cap – no modifications needed
Built for Real Farm Work
These caps fit the legendary Massey Ferguson tractors that have been workhorses on farms for decades, from the popular 135 that was produced by the hundreds of thousands to the larger models used for crop cultivation, hay production, and livestock operations. Whether you’re running a compact utility tractor or one of the bigger row-crop machines, this cap does the same job the factory original did.
Made to Last
Farm equipment caps take a beating from constant removal during oil checks, exposure to engine heat, and the inevitable bump from tools or loader attachments. This one’s built with materials that stay flexible through temperature changes and resist cracking from UV exposure and vibration.
Installation Notes
Installation is as simple as unscrewing the old cap and threading on the new one. If your old cap has been on there a while and seems stuck, a little penetrating oil around the threads helps with removal. Make sure the sealing surface is clean before installing the new cap for the best seal.
