Description

When you’re rebuilding an International Harvester engine and you notice that telltale knock or rattle at idle, worn piston pin bushings are often the culprit. These small but critical bushings sit inside the connecting rod and provide the smooth bearing surface that lets the piston pin move freely while keeping everything tight and properly aligned. Replace them now and you’ll save yourself from more expensive engine damage down the road.

What You’re Getting

Precision-manufactured bushings that restore proper piston pin clearance and eliminate engine knock
Quality TISCO construction built to handle the heat and pressure inside your engine
Direct replacement design that fits like the original factory bushings
Set of four bushings—exactly what you need for a complete four-cylinder engine rebuild

Built for Real Farm Work

This bushing is part of complete engine overhaul kits that include pistons, rings, pins, retainers, and all the gaskets needed for International Harvester tractors. Whether you’re restoring a classic Farmall for weekend farming or rebuilding the engine in your daily-use utility tractor, these bushings are essential for getting your International running smooth and quiet again.

Made to Last

Engine bushings take tremendous abuse from constant heat, oil, and the forces of combustion. TISCO builds these bushings to handle the demanding conditions inside your International’s engine, using materials that maintain proper clearances even after thousands of hours of operation.

Good to Know

Installing piston pin bushings requires specialized tools and machine shop work—this isn’t typically a job for the farm shop. Your machinist will need to bore the bushings to the correct inside diameter to match your piston pins. Since you need four bushings per engine, this part number gives you exactly what you need for one complete rebuild without having to order extras.
