Description

When your Allis Chalmers starts knocking or you notice metal shavings in the oil, it’s usually the rod bearings calling for attention. These hardworking components take a beating keeping your connecting rods and crankshaft happy, and when they wear out, the whole engine suffers. This complete rod bearing kit gives you everything needed to get your 301 cubic inch diesel running smooth and quiet again.

What You’re Getting

Complete set of standard-size rod bearings for all six cylinders
Precision-manufactured to OEM specifications for proper clearances
High-quality bearing material that handles the heat and pressure of diesel operation
Ready to install—no machining or modifications needed

Built for Real Farm Work

This kit works with Allis Chalmers tractors powered by the 301 CID diesel engine, typically found in larger row-crop and utility models from the era when Allis built some seriously tough machines. Whether you’re plowing, cultivating, or running a PTO-driven implement, this engine was designed to handle long days and heavy loads.

Made to Last

TISCO builds these bearings to handle the punishment that comes with diesel engine operation. The bearing material is formulated to withstand the higher compression ratios and combustion pressures of diesel fuel, while the precision tolerances ensure proper oil clearance for reliable lubrication.

Installation Notes

This is definitely an engine-out job that’s best left to an experienced mechanic or machine shop. Check your crankshaft journals for wear or scoring before installing new bearings—if the crank needs work, now’s the time to do it. Engine bearings must be ordered seperately from overhaul kits, so make sure you’ve got everything you need before starting the job.
