Description
When your trusty Allis Chalmers starts blowing smoke or burning oil faster than it burns fuel, it’s time for more than just a tune-up. This complete overhaul kit brings everything you need to rebuild that 125 cubic inch four-cylinder gas engine from the ground up, getting you back to the field work that pays the bills.

Built for Real Farm Work
This kit fits the classic Allis Chalmers tractors with the 125 CID engine found in the 1B Series, B Series, B125 Series, B15 Series, C Series, and CA Series models. These are the orange machines that built American agriculture—utility tractors perfect for everything from cultivating to hay work to running the PTO for all sorts of farm tasks.
Made to Last
Tru Power Engine Kit quality means you’re getting components built to handle the demands of farm life. The pistons and rings are engineered for the compression ratios and operating conditions these engines were designed for, while the gaskets use materials that stand up to heat cycles and vibration.
Installation Notes
This is a complete overhaul kit, so plan on having your engine out of the tractor and on a stand. The overbore pistons give you options if your cylinders need work, and having both sizes means you can choose the right fit for your block’s condition. A good machine shop can help determine which bore size you need.
