Description

When you’re rebuilding an International Harvester engine or dealing with excessive piston noise and wear, these piston pin bushings are a critical component you can’t overlook. The piston pin connects the piston to the connecting rod, and these bushings provide the smooth bearing surface that keeps everything moving properly. Without good bushings, you’ll get metal-on-metal contact that destroys pistons, pins, and rods fast.

What You’re Getting

Set of 4 bushings for complete engine rebuild – one for each piston/rod assembly
TISCO quality construction that meets OEM specifications for durability
Precision-machined inner diameter for smooth piston pin operation
Proper clearances that maintain oil film while preventing excessive play

Built for Real Farm Work

These bushings fit International Harvester engines found in tractors that have powered American farms for decades. Whether you’re rebuilding a Farmall that’s been in the family for years or fixing up a project tractor, these bushings restore the tight tolerances your engine needs for reliable operation and long life.

Made to Last

Engine rebuilds aren’t something you want to do twice, so these bushings are made from materials that can handle the constant loading and unloading that happens thousands of times per minute. They’re designed to work with proper oil pressure and maintain their dimensions even under the heat and stress of hard pulling in tough conditions.

Installation Notes

Installing piston pin bushings requires specialized tools and machine shop work – they need to be pressed into the connecting rods and then honed to final size for proper pin clearance. Most farmers take their rods to a machine shop for this work as part of a complete engine rebuild. Always replace all four bushings at once, even if only some look worn.
