Description

When your International Harvester tractor’s engine starts knocking or showing low oil pressure, worn main bearings are likely the culprit. This .010 inch oversize main bearing kit gives you the precise fit needed after your crankshaft’s been turned, restoring proper clearances and getting your tractor back to reliable operation. No need to guess at measurements—this kit’s designed to handle the loads and stresses of real farm work.

What You’re Getting

Precision-sized .010 inch oversize bearings for proper crankshaft clearance after machining
Complete set of main bearings for thorough engine rebuild
Quality TISCO construction built to handle farm equipment demands
Direct replacement for original International Harvester main bearings

Built for Engine Rebuilds

This bearing kit is designed for International Harvester tractors that need a proper engine rebuild with a turned crankshaft. When your engine’s been running hard for years—pulling plows through tough ground, running PTO equipment, or handling heavy loader work—those main bearings take a beating. The .010 oversize specification means this kit’s made for crankshafts that have been machined to restore smooth surfaces.

Made to Last

TISCO builds these bearings to handle the constant stress and heat cycles that farm engines endure. The materials and construction are matched to original International Harvester specifications, so you get the durability needed for seasons of reliable operation. These aren’t cheap bearings that’ll fail when you need your tractor most.

Installation Notes

This is a precision rebuild job that requires proper machining and measurement. Make sure your crankshaft journals are turned to exactly .010 inch undersize before installing these bearings. Proper bearing clearance is critical—too tight and you’ll have lubrication problems, too loose and you’ll get knocking and premature wear. Always check bearing clearances with plastigage before final assembly.
