Description

When your engine’s running rough or you’re hearing that telltale knocking sound, it’s time to take a serious look at those rod bearings. These little workhorses take a beating, spinning thousands of times per minute while supporting the connecting rods that transfer power from your pistons to the crankshaft. A worn bearing set can turn a reliable tractor into an expensive headache real quick.

What You’re Getting

Complete set of connecting rod bearings for all four cylinders in your 125 CID engine
Precision-manufactured to OEM specifications so everything fits and works like it should
Quality materials that can handle the heat and pressure of hard farm work

Built for Real Farm Work

This bearing kit is designed specifically for Allis Chalmers tractors with the 125 cubic inch 4-cylinder gas engine. Whether you’re running an older compact tractor for loader work around the farmyard or using it for lighter field operations, these bearings will help keep your engine running smooth and strong for years to come.

Made to Last

Engine bearings are one of those parts where quality really matters. These TISCO bearings are built to handle the constant stress and heat cycles that come with farm work, from cold morning starts to long days in dusty fields. The materials and manufacturing meet OEM standards so you know they’ll hold up.

Good to Know

Installing rod bearings requires pulling the oil pan and removing the connecting rod caps, so it’s definitely an engine-out or major teardown job. While you’re in there, it’s a good time to check your main bearings, rings, and other wear items. Make sure to torque everything to spec and use fresh oil and filters when you fire it back up.
