Engine Main Bearing Kit for International Harvester Tractors

Description

When you start hearing that deep knocking sound from your International Harvester’s engine, especially after it’s warmed up or under load, your main bearings are telling you they’ve had enough. These bearings are what keep your crankshaft properly positioned and spinning smoothly—and when they wear out, you’re looking at serious engine damage if you don’t address it quickly. This standard-size main bearing kit gives you the precision-manufactured bearings your IH engine needs to keep running strong for years to come.

What You’re Getting

• Complete set of standard-size main bearings designed for precise crankshaft fit and proper oil clearance
• Quality materials and precision manufacturing that deliver the same reliable performance as original equipment
• Direct replacement for worn original bearings—no machine work required for standard installations
• Professional-grade construction that handles the heat, pressure, and constant rotation of farm work

Built for Real Farm Work

This bearing kit fits International Harvester tractors across multiple series including the reliable 100 and 200 series, plus Super A-1 and Super AV-1 models. Whether you’re running a utility tractor for chores around the farm or putting hours on a larger row-crop machine during planting and harvest, these bearings handle the demanding conditions that come with agricultural work.

Made to Last

Farm engines take a real beating from constant operation under heavy loads, temperature swings, and varying oil conditions. These replacement bearings use quality materials and precision manufacturing to deliver reliable performance, with proper design to keep oil where it belongs even in demanding field conditions.

Installation Notes

This is a job for someone comfortable with major engine work—you’ll need to remove the oil pan and likely the engine to access the main bearing caps. The bearings are a direct replacement with no modifications needed for proper fit, but use proper bearing installation tools to avoid damage during assembly and always clean the crankshaft and bearing caps thoroughly before installation. Check your crankshaft journals for wear or scoring while you’re at it—damaged journals will quickly destroy new bearings.
