Description
When you’re hearing blow-by whistling past worn rings or noticing blue smoke on startup, it’s time to get your Allis Chalmers back to running clean and strong. This piston ring set works with classic Allis Chalmers tractors including the B, C, CA, G, WC, WD, and WD45 models that came with the reliable 266 cubic inch four-cylinder gas engine. A good ring set like this one restores compression and keeps oil where it belongs—in the crankcase, not burning in the combustion chamber.
What You’re Getting
- Complete ring set for four pistons with 4-1/8 inch overbore specification
- Three compression rings per cylinder at 3/32 inch thickness for proper sealing
- One oil control ring per cylinder at 1/4 inch for effective lubrication management
- Quality TISCO construction that’s built to handle the demands of farm work
Built for Real Farm Work
This ring set is designed for the workhorse 266 CID four-cylinder engines that powered so many reliable Allis Chalmers tractors through the decades. Whether you’re running a WC on hay equipment, using a WD45 for cultivation work, or keeping a vintage CA running for light farm duties, these rings restore the power and efficiency your tractor had when it first rolled off the line.
Made to Last
TISCO has been making quality tractor parts for decades, and these rings are no exception. They’re manufactured to handle the heat cycles, dirt, and long hours that come with farm life. The overbore specification means they’ll work properly in cylinders that have been machined to restore proper clearances.
Good to Know
This is an overbore ring set, so make sure your cylinders have been properly machined to 4-1/8 inch bore diameter before installation. If you’re doing the work yourself, take your time with ring installation—they’re precision parts that don’t like being forced. A ring compressor tool makes the job much easier and prevents damage to the rings during piston installation.
