Exhaust Manifold Stud for Massey Ferguson 5400, 6400, and 7400 Series Tractors

Description

When you’re pulling into the shop and hear that ticking exhaust leak getting louder as the engine heats up, chances are you’ve got a broken manifold stud. It’s one of those parts that doesn’t look like much, but when it fails, it can shut down your whole operation. This exhaust manifold stud is engineered to handle the extreme heat and constant expansion cycles that make the originals crack and snap off in the head.

What You’re Getting

• Precision-threaded stud built for the high-stress exhaust environment
• Heat-resistant materials that won’t weaken from constant thermal cycling
• Direct replacement that threads into the original holes without modification
• Proper length and thread pitch to secure the manifold correctly

Built for Real Farm Work

This stud fits across Massey Ferguson’s workhorse lineup—from the utility 5400 series tractors you use for loader work and hay hauling, up through the big 6400 and 7400 series machines that power through heavy tillage and harvest operations. These tractors handle serious farm duties where exhaust integrity affects both performance and operator comfort. Whether you’re running Perkins or SISU engines, reliable exhaust mounting is critical for keeping power where it belongs.

Made to Last

Exhaust manifold studs take more abuse than most people realize—they’re constantly expanding and contracting with temperature changes while holding a heavy cast iron manifold against engine vibration. This stud is built to handle the constant heating and cooling cycles with precision construction that matches OEM specifications and proper materials to resist thermal stress. The threading won’t strip out under torque, and the steel won’t become brittle from heat exposure.

Installation Notes

Remove the old manifold carefully—those studs love to snap off after years of heat cycling. Clean all mating surfaces thoroughly and check for cracks in the head before installing. Always use new gaskets and studs—don’t try to reuse the old hardware. If you’ve got a broken stud in the head, address it properly with extraction tools before installing the replacement. A little anti-seize compound on the threads makes future service much easier.
