Description

When you’re working those older Case IH tractors hard and notice exhaust noise or smoke where it shouldn’t be, a cracked or warped exhaust manifold is usually the culprit. This part collects all that hot exhaust gas from your engine’s cylinders and routes it safely out through the exhaust system—when it fails, you’ll know it right away from the extra noise and fumes creeping into the cab.

What You’re Getting

Heavy-duty cast iron construction that stands up to the extreme heat cycles these old tractors dish out
Precise port alignment ensures proper exhaust flow and prevents back-pressure that robs power
Quality casting with smooth surfaces that seal tight against head gaskets
Direct OEM replacement that bolts right up without modifications or adapters

Built for Real Farm Work

This manifold fits a wide range of those reliable Case IH utility tractors from the 1970s and 80s. Whether you’re running a 275 on the farm lot, a 354 for hay work, or one of the bigger 434s for field cultivation, these tractors were built to work every day. The manifold has to handle all that heat from long hours under load while dealing with the constant vibration and temperature swings that come with farm life.

Made to Last

These manifolds are cast from quality iron that’s designed to expand and contract with engine heat without cracking. The mounting surfaces are machined flat so your gaskets seal properly, and the ports are sized to match your engine’s exhaust valves for smooth gas flow. This isn’t some cheap aftermarket piece—it’s built to the same specs as what came on your tractor originally.

Good to Know

When installing, always use new exhaust manifold gaskets and check that your mounting studs aren’t damaged or stretched. Clean all the old gasket material off both surfaces with a scraper—any leftover bits will cause leaks. Tighten the bolts evenly in a crisscross pattern to avoid warping, and don’t forget to reconnect your exhaust pipe with a new gasket there too.
