Description
Nothing ruins your day like oil dripping on hot engine parts or that telltale smell of burning oil while you’re trying to get work done. When your rocker cover gasket starts to fail, you’ll see oil pooling around the valve cover or coating the side of your engine block. This rubber gasket creates the seal between your rocker cover and cylinder head, keeping oil where it belongs and dirt where it doesn’t.
What You’re Getting
- Precision-molded rubber construction designed specifically for 4-cylinder Phaser engines
- Heat-resistant compound that handles the temperature swings of daily farm work
- Proper thickness and flexibility to maintain a tight seal through engine vibration
- Direct replacement design that fits exactly like the original factory gasket
Built for Real Farm Work
This gasket fits your Massey Ferguson tractors equipped with the reliable Perkins 1004.4 four-cylinder engine. Whether you’re running a 3075 for hay work, a mid-range 4200 series for row crop farming, or a 6100 series for heavy field operations, that engine sees everything from early morning starts in cold weather to long summer days under full load. The rocker cover gasket takes the brunt of oil pressure and engine heat while keeping everything sealed tight.
Made to Last
This isn’t just any rubber gasket – it’s engineered for the specific requirements of agricultural diesel engines. The compound resists oil degradation, temperature extremes, and the constant heating and cooling cycles that come with tractor work. It maintains its flexibility even after years of service, so you won’t be doing this job again next season.
Installation Notes
Clean both mating surfaces thoroughly before installation – any old gasket material or oil residue will cause leaks. A light coating of clean engine oil on the gasket helps with installation and prevents tearing. Tighten the rocker cover bolts evenly in a crisscross pattern to the proper torque specification – over-tightening can distort the gasket and cause leaks.
