Description

When your classic Allis Chalmers starts losing compression or burning oil, worn piston rings are usually the culprit. You’ll notice the telltale blue smoke on startup, oil consumption between changes, and maybe that rough idle that wasn’t there before. This complete piston ring set gets your 201 or 226 cubic inch four-cylinder gas engine back to sealing tight and running clean.

What You’re Getting

Complete set of rings for all 4 cylinders – no guessing about quantities
Includes three 1/8 inch compression rings and one 3/16 inch oil ring per cylinder
Standard 4 inch bore size fits original cylinders without machine work
Quality construction designed to handle the demands of farm work
Direct replacement for original equipment – no modifications needed

Built for Vintage Allis Workhorses

These engines powered many of the classic orange Allis Chalmers tractors that built the reputation for reliability we still respect today. Whether you’re keeping a vintage B, C, CA, or WD running for farm work or restoration, these are the same displacement engines that pulled plows and powered implements across countless acres. The 201 and 226 CID motors were workhorses that farmers depended on day after day.

Made to Last

Farm equipment from this era was built to run for decades, and these replacement rings are designed with the same durability in mind. The ring materials and construction handle the temperature swings and constant use that come with tractor work, giving you the compression and oil control you need to keep your vintage machine productive.

Installation Notes

Ring installation requires careful attention to ring gaps and proper piston orientation. Make sure to check ring end gaps before installation and file if needed. A ring compressor tool makes the job much easier and prevents cracked rings during piston installation.
