When your engine starts marking its territory with oil spots or you catch that distinctive whiff of burning oil around the flywheel area, it’s time to address that worn rear main seal. This packing material creates a tight seal between the crankshaft and the rear main bearing cap, keeping oil where it belongs—inside your engine instead of leaking into the clutch housing or dripping on the ground.
What You’re Getting
- Durable packing material designed to handle crankshaft movement and engine heat
- Proper compression characteristics that create a reliable seal without binding
- Resistant to engine oil and temperature extremes from cold starts to heavy loads
- Direct replacement that installs with standard tools and techniques
Built for Real Farm Work
This packing works in Massey Ferguson tractors where the rear crankshaft seal needs attention. Whether you’re running a utility tractor for daily chores or a bigger machine for serious field work, a properly sealed rear main bearing keeps oil from contaminating your clutch and transmission components while preventing costly oil loss.
Made to Last
Engine sealing has come a long way, but sometimes the tried-and-true packing method is what your particular tractor needs. This material is engineered to compress properly during installation and maintain its sealing properties even as it adjusts to normal crankshaft movement and thermal cycling from engine operation.
Good to Know
Installing rear main packing typically requires splitting the tractor between the engine and transmission, so it’s often done during clutch work or other major repairs. Clean all surfaces thoroughly and follow proper torque specifications on the bearing cap bolts. Take your time getting the packing positioned correctly—rushing this job usually means doing it over.
