Description
When your exhaust manifold starts cracking or developing leaks, you’ll notice it right away—increased engine noise, exhaust fumes creeping into the cab, and that telltale ticking sound that gets worse under load. A compromised manifold doesn’t just make your tractor louder; it affects engine breathing and can lead to performance issues that’ll have you scratching your head. This replacement manifold gets your Perkins engine breathing properly again and eliminates those troublesome leaks that make long days in the field even tougher.
What You’re Getting
- Heavy-duty cast construction that handles the extreme heat cycles your engine puts it through daily
- Precision-engineered ports that maintain proper exhaust flow for optimal engine performance
- Direct OEM replacement design—mounts right up with your existing hardware and gaskets
- Quality materials that resist the thermal stress and corrosion that destroy cheaper manifolds
Built for Real Farm Work
Your Massey Ferguson 390T, 398, or 698T is likely handling everything from heavy tillage work to hay operations where consistent engine performance matters. These mid-horsepower tractors are workhorses on grain farms and livestock operations, often running loaded implements that keep the engine under stress for hours. Whether you’re pulling a disc, running a baler, or handling loader work, proper exhaust flow is critical for maintaining power and keeping engine temperatures where they should be.
Made to Last
Exhaust manifolds take a beating in agricultural applications—constant temperature swings from cold starts to full-power operation, vibration from heavy implements, and exposure to dust, moisture, and chemicals. This manifold is built specifically for these demanding conditions with robust casting that maintains structural integrity through thousands of heat cycles.
Good to Know
Always use a new exhaust manifold gasket during installation and make sure all mounting surfaces are clean and flat. While many experienced farmers handle manifold replacement themselves, the work involves hot exhaust components and proper torque specifications are critical for preventing leaks. If you’re not comfortable with the job, having it done by a qualified mechanic familiar with Perkins engines is money well spent.
