When your old John Deere tractor starts knocking or running rough, worn piston pin bushings are often the culprit. These little bushings might not look like much, but they’re what keep your pistons moving smoothly in their cylinders. When they wear out, you get that unmistakable rapping noise that tells you it’s time for an engine rebuild—and this bushing is a critical piece of that puzzle.
What You’re Getting
- Precise fit bushing that restores proper piston pin clearances in your engine
- Quality construction that handles the heat and pressure of gas engine operation
- Direct replacement for worn original bushings—no machining required
- Sold individually so you can order exactly what your engine needs
Built for Classic John Deere Power
This bushing works in several of John Deere’s workhorse gas engines from the classic era. The 201 and 227 CID four-cylinder engines powered many utility tractors, while the 301 and 340 CID six-cylinder engines ran the bigger row-crop machines that did the heavy lifting on farms. These engines were built to last, and with the right parts, they’ll keep running for decades more.
Made to Last
Engine rebuilds aren’t something you want to do twice, so this bushing is made from quality materials that can handle the constant movement and heat cycles inside your engine. The bore is precision-sized to work with your piston pins, and the outside diameter fits snugly in the connecting rod without being too tight.
Installation Notes
Installing these bushings requires engine teardown and proper machining tools—this isn’t a weekend job in the barn. Your machine shop will need to press out the old bushings, check bore sizes, and install the new ones with the right clearances. Make sure to replace all the bushings in the engine, not just the obviously worn ones.
