Description

When your Oliver tractor starts knocking or you notice oil pressure dropping, the crankshaft main bearings are often the culprit. These crucial components keep your crankshaft properly positioned and spinning smoothly inside the engine block. A worn bearing set means decreased power, increased oil consumption, and potential catastrophic engine failure if you keep pushing it. This standard-size main bearing kit gets your Oliver’s heart beating strong again.

What You’re Getting

Complete set of main bearings sized to original factory specifications
Precision-manufactured to maintain proper crankshaft clearances
High-quality materials that handle the heat and pressure of hard work
Standard sizing works with unground crankshafts in good condition

Built for Real Farm Work

This bearing kit is designed for Oliver tractors that have seen their share of long days and heavy loads. Whether you’re running an older Oliver row-crop tractor for cultivation work or using a utility model for loader duties around the farm, these bearings restore the engine’s foundation to handle whatever you throw at it.

Made to Last

TISCO builds these bearings to withstand the constant stress and vibration that comes with agricultural work. The materials and construction meet original equipment standards, so you’re getting the same quality that kept these tractors running for decades in the first place.

Good to Know

This kit is for standard-size applications where the crankshaft hasn’t been machined undersize. If your crank has been ground or you’re unsure about clearances, measure everything before ordering. During installation, check crankshaft condition carefully and verify proper oil clearances with Plastigage. Clean everything thoroughly—old bearing material and metal particles are engine killers.
