Clevite John Deere 404 CID Eng 4.250in Bore Piston Pin Bushing

When you're rebuilding the engine in your John Deere with a 404 CID engine, getting the connecting rod and piston pin fit just right is crucial. This piston pin bushing from Clevite is designed to be pressed into the connecting rod, creating a precise bore for the piston pin to rotate within. A worn or improperly sized bushing can lead to excessive play, noise, and premature engine wear, so using a well-built replacement is key to a solid rebuild.

This bushing is made to fit a 4.250 inch bore, which is specific to the 404 CID John Deere engine. Clevite is a well-known name in engine bearings and components, and this bushing is made to meet the demands of engine rebuilding. Proper installation involves pressing this bushing into the connecting rod, and then reaming or honing it to the exact piston pin diameter for a perfect fit. This ensures the connecting rod moves smoothly and without excessive friction against the piston pin.
