Description

When your International Harvester engine starts knocking or losing oil pressure, chances are it’s time for new main bearings. This kit gives you everything you need to restore that tight, quiet operation that keeps your tractor running strong through long days in the field. Main bearings are what keep your crankshaft centered and supported—when they wear out, you’ll know it.

What You’re Getting

Complete set of .010 inch oversize main bearings for proper clearance on worn crankshafts
TISCO quality construction that meets or exceeds original equipment standards
Precision-manufactured bearings designed to handle the loads and stresses of farm work
Direct replacement for original International Harvester bearing sets

Built for Real Farm Work

This kit fits International Harvester engines in the 100 series, 200 Series, Super A-1 Series (prior to S/N 310300), Super AV-1 Series (prior to S/N 310300), and Super C Series tractors. Whether you’re running a Farmall through harvest or pulling a plow in spring, these bearings handle the demanding conditions that come with real farm work.

Made to Last

Engine work isn’t something you want to do twice. TISCO builds these bearings to handle the punishment that comes with tractor work, designed to keep running smooth even when you’re working in dusty conditions. The .010 oversize specification means they’re engineered for crankshafts that have been machined to remove wear and restore proper clearances.

Good to Know

This is precision work that requires proper tools and measurement. The .010 oversize bearings are specifically for crankshafts that have been turned .010 inch undersize to clean up wear. Make sure your crank has been properly machined and measured before installation. A clean work area and torque wrench are essential for proper bearing installation.
