Description

When your Allis Chalmers engine starts knocking or running rough, worn rod bearings are often the culprit. These critical engine components take a beating from constant pressure and heat, especially in older 201 and 226 cubic inch gas engines that have been working hard for decades. This undersized bearing kit gives you a second chance at restoring your engine to smooth operation without breaking the bank on a full rebuild.

What You’re Getting

Complete set of .020 undersized rod bearings engineered to fit after crankshaft turning
TISCO quality construction that meets or exceeds OEM specifications for durability
Precision-machined bearings that provide proper oil clearance and smooth operation
Complete kit contains all the rod bearings needed for your 4-cylinder engine rebuild

Built for Real Farm Work

These bearings are designed for the 201 and 226 cubic inch 4-cylinder gas engines found in many classic Allis Chalmers tractors. Whether you’re restoring a vintage orange machine for weekend farm work or keeping an old reliable running for daily chores, these engines were workhorses in their day and can be again with proper bearing replacement.

Made to Last

Rod bearings live in one of the toughest environments inside your engine – constant pressure, high temperatures, and metal-to-metal contact with only a thin film of oil for protection. TISCO builds these bearings with materials that can handle the stress and provide years of reliable service when properly installed and maintained.

Installation Notes

This is an undersized bearing kit, which means your crankshaft journals need to be turned .020 down by a qualified machine shop before installation. The good news is that turning the crank is often more cost-effective than replacing it, and these bearings will restore proper clearances for smooth, quiet operation. Always check your connecting rod condition and torque specs during installation.
