This TISCO main bearing set gets your International Harvester back to running smooth and strong, protecting that crankshaft investment and giving you the reliability you need when the work can’t wait.

Built for Real Farm Work
This bearing set is designed for the International Harvester tractors that built America’s farms – from the smaller utility models handling chores around the farmstead to the bigger row-crop machines pulling through heavy clay or corn stubble. Main bearings support the crankshaft and handle the tremendous loads created when your engine’s pistons fire under full power.
Made to Last
These aren’t cheap bearings that’ll give you trouble next season. TISCO manufactures these to handle the constant stress of farm work – whether you’re pulling a loaded manure spreader up a hill, running a PTO-driven baler all day, or pushing snow with a blade. The precision tolerances ensure proper oil flow and heat dissipation that keeps your engine running right.
Installation Notes
This is a job for someone comfortable with engine work or your trusted mechanic. You’ll need to pull the oil pan and remove the crankshaft to install these properly. While you’re in there, it’s smart to check your connecting rod bearings too – they often wear at similar rates. Have your crankshaft checked for out-of-round or scoring before installing new bearings.
