Description
When you start hearing that telltale knocking sound during startup or under load, there’s a good chance your piston pin bushings are telling you they’ve had enough. This connecting rod bushing is what provides the smooth bearing surface between your connecting rod and the wrist pin, transferring power from your pistons to the crankshaft. When bushings wear out, you’ll hear that telltale metallic knocking – especially when the engine’s cold or under load. This honeable bushing gets your 6-cylinder turbocharged diesel engine back to running smooth and quiet.
What You’re Getting
- Honeable design lets you customize the fit for your exact piston pin specifications
- Durable construction built to handle the demanding loads of turbocharged diesel operation
- Precision bore that ensures proper oil clearance once machined to size
- Direct replacement for connecting rods marked R57303 or R67320
- Six bushings needed for complete engine rebuild
Built for Real Farm Work
This bushing is designed for John Deere’s 466 CID 6-cylinder turbocharged diesel engines that power serious farm equipment. These are the workhorses that run loader tractors, heavy tillage rigs, and other demanding applications where consistent power delivery matters. Whether you’re moving dirt, pulling heavy implements, or running long hours in the field, these engines need bushings that can handle the punishment.
Made to Last
Engine bushings take incredible punishment – they deal with combustion pressures, heat cycles, and the constant reciprocating motion of pistons firing thousands of times per hour. This bushing is manufactured to handle those conditions while providing the precise bearing surface your connecting rods need for thousands more hours of reliable operation.
Installation Notes
These bushings come ready to install but require final honing to achieve the exact bore diameter for your piston pins. Any competent machine shop can handle this work – just make sure they understand your final specifications. Since you need six bushings for the complete engine, it’s smart to do them all at the same time to ensure consistent clearances throughout.
