Built for Real Farm Work
This kit is designed specifically for Allis Chalmers tractors equipped with the 201 cubic inch flat head four-cylinder gas engine. These engines powered many of the utility and row-crop models that you’ll find working small farms, handling loader work, running hay equipment, and pulling implements. The flat head design was known for its simplicity and durability—easy to service and built to run for decades.
Made to Last
TISCO has been manufacturing quality engine rebuild components for years, and they understand what it takes to handle the demands of farm use. The sleeves are cast iron construction that matches OEM specifications, while the pistons feature the proper flat-top design with quality aluminum alloy that handles heat and pressure cycles. These aren’t shortcuts—they’re the same quality parts professional engine rebuilders rely on.
Good to Know
This is an overbore kit, so your cylinders will need to be bored to 4-1/8 inch by a qualified machine shop. The overbore gives you room to clean up cylinders that have seen years of faithful service and gets you back to proper compression and oil control. Make sure to have your block pressure tested and decked while you’re at it—it’s the right time to do it properly.
