Description

When you’re doing an engine rebuild or dealing with worn piston pin bushings, this honeable bushing gives you the flexibility to machine it to exact specs for your specific John Deere diesel engine. Whether you’re working on that older tractor that’s put in decades of hard work or trying to get precise clearances on a rebuilt engine, having bushings you can hone to size saves trips to the machine shop and ensures a proper fit.

What You’re Getting

Honeable design lets you machine to exact clearances for your specific application
Works across multiple John Deere diesel engines from 254 CID up to 404 CID
Quality TISCO construction that meets OEM specifications
Bushings sold individually so you can order the exact quantity needed

Built for Real Farm Work

This bushing fits a range of John Deere diesel engines including the 254 CID 4-cylinder (4 bushings needed), 270 CID 4-cylinder (4 needed), and both the 381 CID and 404 CID 6-cylinder engines (6 bushings each). These are the engines found in many of the workhorse John Deere tractors that have been the backbone of American farms for decades. Whether it’s powering a utility tractor or a larger row-crop machine, proper piston pin bushings are critical for engine longevity.

Made to Last

TISCO engineered these bushings to handle the constant stress and heat cycles that diesel engines endure. The material is selected specifically for its wear characteristics and ability to maintain proper clearances under load. Since these are honeable, you can achieve the precise fit that factory engines had when new, which means better oil control and longer engine life.

Installation Notes

The honeable design means you’ll need to machine these to final size after installation – this isn’t a drop-in replacement. Work with a competent machine shop that understands piston pin clearances, as proper fitment is crucial for engine performance and longevity. Always replace all bushings in the engine at the same time to ensure even wear patterns.
