Description

When you see coolant leaking onto the ground under your tractor or notice white smoke coming out the exhaust, you know it’s time for a head gasket job. A blown head gasket can turn your reliable workhorse into an expensive paperweight, but this complete gasket set gets everything you need to seal up your AR engine and get back to farming. No more mixing coolant with oil or losing compression when you need power most.

What You’re Getting

Complete set includes all gaskets and seals for a proper top-end rebuild
Quality construction that handles the heat and pressure of hard farm work
Precision-fit seals that stop leaks between the head and block
Includes intake and exhaust manifold gaskets for a complete job
Note: Individual head gasket is available separately as part 63414

Built for Real Farm Work

This gasket set works with the 4-cylinder engines in your MF 4200 and 4300 series tractors, including the 4235 and 4335 models. It also fits the AR engines in Massey Ferguson 8900 series telehandlers like the 8925, 8926, 8937, and 8939. Whether you’re running a compact utility tractor for livestock work or operating a telehandler for hay and feed operations, these engines see plenty of stress from heavy loads and long hours.

Made to Last

AR engines are known for their reliability, but when gaskets fail, they fail completely. This set uses quality materials that can handle the thermal cycling and combustion pressures these engines produce. The gaskets are designed to maintain their seal through countless heat-up and cool-down cycles, so you won’t be doing this job again anytime soon.

Installation Notes

When installing, always clean the block threads thoroughly and use a thread chaser to clean the holes. Apply a small amount of engine oil to the threads before torquing, and follow the factory torque sequence exactly. Most experienced mechanics recommend replacing head studs anytime you have the head off, especially on older engines. Take your time with surface prep—a clean, flat surface is critical for gasket life.
