Complete Engine Overhaul Kit for Allis Chalmers B Series and C/CA Series Gas Tractors

Description

When your old Allis starts burning oil, losing power on hills, or making noises it never used to make, it’s telling you the engine needs more than just fresh filters and oil. If you’ve been nursing along one of those reliable B series or C/CA tractors for years, you know they’ll run forever with the right care. This complete overhaul kit gives you everything needed to bring that 125 cubic inch four-cylinder gas engine back to like-new condition without having to hunt down parts from three different suppliers.

What You’re Getting

• Complete rebuild components including sleeves, pistons, rings, pins, cam bearings, and valves for a thorough restoration
• Full gasket set, valve springs, guides, and keys so you’re not stuck waiting for one missing piece
• Both standard 3-3/8 inch bore and 3-7/16 inch overbore supplied so you can match your cylinder condition
• Quality Tru-Power components that meet original factory specifications
• Everything organized and packaged together—no more ordering parts piecemeal

Built for Real Farm Work

This kit fits the popular B series tractors that have been the backbone of small farms for decades, along with the C and CA series models that followed. These were the workhorses used for everything from cultivating row crops to running hay equipment and doing general farm chores. The 125 CID engine was known for its reliability and smooth operation when properly maintained.

Made to Last

Farm engines need to handle dust, heat, cold starts, and long days under load. This Tru-Power kit uses quality materials and precise manufacturing to restore your engine to original performance standards. The components are built to handle the steady work these tractors were designed for, season after season.

Good to Know

This is a complete overhaul kit, so plan on having the block machined and doing a full teardown. You’ll need to order engine bearings separately to complete the rebuild. Having both bore sizes included gives you flexibility depending on what your cylinders measure out to. Take your time with the assembly—these engines will reward careful work with years of dependable service.
