Description
When your Case 1490 or 1494 starts sounding like a freight train instead of the smooth-running diesel workhorse it should be, that's your muffler telling you it's time for a replacement. A blown-out or rusted-through muffler doesn't just make for an uncomfortable ride—it affects exhaust flow and engine performance while making those long days in the field a lot harder on your ears.
What You're Getting
- Vertical oval body design that matches your tractor's original configuration perfectly
- Precision-sized 2-1/4 inch inlet and outlet diameters for proper exhaust flow
- 44-inch overall length with proper shell and pipe dimensions for exact factory fit
- Heavy-duty construction built to handle diesel exhaust temperatures and farm conditions
- Direct replacement that uses your existing mounting hardware and connections
Built for Real Farm Work
This muffler fits both the 1490 and 1494 diesel tractors—reliable workhorses that powered through countless acres of tillage, planting, and harvest work throughout the '70s and '80s. These tractors were built for long days handling heavy implements, and they need exhaust components that can keep up with that demanding work schedule.
Made to Last
Farm mufflers face constant temperature swings, road dust, moisture, and vibration from field work. This replacement is built with materials that resist the rust-through and heat damage that eventually claim original equipment. The internal baffling is designed specifically for diesel exhaust characteristics, providing effective sound reduction while maintaining the proper back pressure your engine needs.
Installation Notes
This is a direct replacement that bolts right in place of your original muffler using existing clamps and mounting points. Before installation, check your exhaust pipe condition—after decades of farm work, clamps and gaskets often need attention too. A little penetrating oil on old exhaust hardware makes removal much easier, and new clamps ensure a leak-free installation.
