Description
When your International Harvester tractor starts knocking or you hear a rhythmic tapping from the engine, there’s a good chance your piston pin bushings are worn out. These little bronze bushings might be small, but they do one of the most critical jobs in your engine—they let the piston pin move smoothly inside the connecting rod while handling thousands of combustion cycles every minute. When they wear out, that smooth operation turns into metal-on-metal contact that’ll wreck your engine fast.
What You’re Getting
- Precision-machined bushing that fits exactly like the original factory part
- Bronze construction that handles heat and provides proper lubrication properties
- Exact bore specifications to maintain proper clearances with your piston pin
- Quality that meets or exceeds OEM standards for long-lasting performance
Built for Real Farm Work
This bushing fits the 4-cylinder gas engines found in International Harvester’s workhorse tractors—the 100 series, 200 Series, Super A-1, Super AV-1, and Super C models. These are the tractors that built American agriculture, from cultivating corn to hay operations to general farm duties. Whether you’re running an old Super C on the back forty or keeping a Farmall 200 running for daily chores, this bushing helps keep that reliable engine ticking.
Made to Last
Engine rebuilds aren’t something you want to do twice, so this bushing is made from quality bronze alloy that can handle the constant hammering of piston forces and the heat cycling of hard farm work. The material composition and machining tolerances are designed to work with your existing piston pin for proper oil film thickness and smooth operation.
Installation Notes
This is an engine-out job that requires pressing the old bushing out of the connecting rod and pressing the new one in—definitely not a barn floor repair. Most engine shops will hone the bushing to final size after installation to ensure perfect fit with your piston pin. Always replace all bushings during an engine rebuild, not just the worst ones.
