Description

When you’re rebuilding that 466 turbo, every little bushing matters—especially the piston pin bushings. These small but critical components control how the piston pin moves inside the connecting rod, and if they’re worn or damaged, you’ll get knocking, power loss, and eventually catastrophic engine failure. This replacement bushing gets your connecting rod assembly back to proper clearances so your engine runs smooth and strong.

What You’re Getting

Precision-made bushing that restores proper piston pin clearance in the connecting rod
Works specifically with connecting rod marked R71074 for perfect fitment
Quality TISCO construction built to handle the forces of a turbocharged diesel
Direct replacement—no modifications needed during your engine rebuild

Built for Real Farm Work

The 466 cubic inch 6-cylinder turbocharged diesel was a workhorse engine used in many John Deere tractors and combines. Whether you’re rebuilding the engine in a combine that’s been harvesting corn for decades or refreshing a tractor engine that’s pulled implements through thousands of acres, these bushings restore the precision your engine needs. Six bushings are used per engine, one in each connecting rod assembly.

Made to Last

Engine rebuilds aren’t something you want to do twice, so every component needs to be right. This bushing is manufactured to handle the constant hammering of a diesel engine under load, with materials and tolerances that match original specifications. The smooth bore finish ensures proper oil flow around the piston pin while maintaining the tight clearances needed for reliable operation.

Good to Know

Installing piston pin bushings requires proper tools and techniques—they need to be pressed in and then reamed to final size for correct pin clearance. Always check connecting rod condition during rebuild, as bent or cracked rods will destroy new bushings quickly. Replace all six bushings during your rebuild even if only some look worn—it’s cheap insurance for your investment in a fresh engine.
