Description
When your trusty International is blowing black smoke or making more noise than a freight train, it’s time to replace that worn-out muffler. A properly working muffler keeps your exhaust quiet, reduces back pressure on the engine, and helps your diesel run cleaner. This vertical muffler is built to the same specs as what came on your tractor from the factory.
What You’re Getting
- Direct replacement vertical muffler that bolts right up to your D310 engine
- Proper inlet and outlet sizing for optimal exhaust flow and performance
- Heavy-duty construction designed to handle the heat and vibration of diesel operation
- Round body design that fits the original mounting configuration
- 40-inch overall length provides the right exhaust path and clearance
Built for Real Farm Work
This muffler fits International Harvester 706, 756, 2706, and 2756 tractors equipped with the D310 diesel engine. These versatile mid-range tractors were workhorses in their day, handling everything from cultivation and planting to loader work and PTO applications. Whether you’re running implements, pulling equipment, or doing general farm chores, this muffler keeps things running smooth and quiet.
Made to Last
Tractor mufflers take a beating from extreme heat, moisture, and road debris. This replacement is built with heavy-gauge steel and proper baffling to handle the constant thermal cycling and vibration that comes with diesel operation. The welded construction and quality materials mean it’ll hold up season after season.
Installation Notes
This is a direct bolt-on replacement that uses your existing mounting hardware. Before installing, check that your exhaust pipe connections are in good shape and replace any gaskets or clamps that look worn. The vertical orientation keeps the outlet pointed up and away from the operator area.
