Description

When your IH tractor starts knocking or you notice metal shavings in the oil, it’s time for new main bearings. A worn crankshaft that’s been turned .020″ oversize needs bearings to match, and running the wrong size will ruin your freshly machined crank in no time. This TISCO builds these bearings to handle the punishment that comes with hard farm work, giving you the precision fit you need to get your engine running smooth again.

What You’re Getting

Complete set of main bearings sized for .020″ oversize crankshaft journals
Precision-manufactured to OEM specifications for proper oil clearances
High-quality bearing material that stands up to heavy loads and long hours
All bearings needed for a complete main bearing replacement job

Built for Real Farm Work

This bearing set fits International Harvester tractors that have had their crankshafts turned .020″ oversize during a rebuild. Whether you’re putting a Farmall back together or rebuilding an IH utility tractor, these bearings give you the same quality that came from the factory. They’re designed to handle the constant loads of field work, from plowing and disking to loader operations and PTO work.

Made to Last

TISCO builds these bearings to handle the punishment that comes with rotary cutter work. They’re designed to keep running smooth even under heavy loads and high temperatures. The bearing material and construction are engineered to maintain proper oil film thickness and resist wear, keeping your engine running reliably season after season.

Installation Notes

Make sure your crankshaft journals measure exactly .020″ oversize before installing these bearings. Take your time during installation to clean out any old grease and debris, and don’t forget to pack the new bearings properly. Check your oil clearances with Plastigage to ensure everything fits correctly before final assembly.
