Main Bearing Kit .020 Oversize for International Harvester Tractors

Description

When you’re hearing that telltale knocking from deep in your International Harvester’s engine, chances are your main bearings are telling you they’ve had enough. After years of hauling heavy loads, running PTO equipment, and putting in long days during planting and harvest, those main bearings take a beating. This .020 oversize bearing kit gives your IH tractor’s crankshaft the tight, reliable support it needs to run smooth and strong again.

What You’re Getting

• Complete main bearing set in .020 oversize to work with a properly turned crankshaft
• Precise fit that restores proper oil clearances and pressure
• Quality construction that handles the loads your IH engine dishes out daily
• Direct replacement for worn original bearings—no guesswork on fit

Built for Real Farm Work

This bearing kit fits a wide range of International Harvester tractors including the 100 and 200 series, Super A-1 and Super AV-1 series machines. Whether you’re running a utility tractor for loader work or a row-crop machine for cultivation and planting, these bearings handle the constant vibration and stress that comes with real farm work. They’re designed for engines that don’t get to take breaks when there’s work to be done.

Made to Last

TISCO builds these bearings to handle the punishment that farm engines dish out, with materials that resist oil breakdown and temperature extremes. The bearing material and construction are designed to withstand the constant expansion and contraction cycles your engine goes through during long workdays. You’ll get reliable performance that lasts season after season.

Good to Know

This is an oversize bearing kit, which means your crankshaft needs to be turned .020 under by a machine shop before installation. Check your crank journals with a micrometer to confirm you need .020 bearings—don’t guess. When installing, keep everything spotlessly clean and follow proper torque specs. A little assembly lube on the bearing surfaces makes initial startup easier on your freshly rebuilt engine.
