Description

When you’re hearing that telltale knocking from deep in your engine or noticing oil pressure dropping on your International Harvester tractor, it’s likely time for new rod bearings. This TISCO rod bearing kit gives you the .020 inch bearings you need to restore proper clearances and get your engine running smooth again. Don’t wait until that knocking gets worse—worn rod bearings can destroy a crankshaft and turn a manageable repair into a major overhaul.

What You’re Getting

Complete set of .020 inch oversize rod bearings designed for proper clearance on a slightly worn crankshaft
TISCO quality construction that meets or exceeds original equipment specifications
Direct replacement for worn factory bearings without requiring machine work to the connecting rods
Precision-engineered bearing material that handles the heat and stress of farm work

Built for Real Farm Work

This kit fits International Harvester 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 with 4-cylinder gas engines. These are the workhorses that have been pulling plows, running loaders, and powering PTO equipment on farms for decades. Whether you’ve got a Farmall A pulling a cultivator or a Super C running a hay mower, reliable rod bearings are essential for keeping your tractor in the field.

Made to Last

TISCO builds these bearings to handle the constant hammering and heat cycling that farm engines endure. The bearing material is formulated to work with the oil pressures and temperatures of these older engines, providing the protection your crankshaft needs while maintaining proper oil clearances for reliable lubrication.

Installation Notes

This is a .020 oversize bearing kit, which means your crankshaft journals need to be turned .020 under standard size by a qualified machine shop before installation. While you’ve got the engine apart, check your connecting rods for straightness and the rod bolts for stretch. A torque wrench is essential for proper reassembly—these older engines are particular about bearing clearances and bolt torque specifications.
