Description
When your trusty Allis Chalmers starts burning oil, losing compression, or just doesn’t have the power it used to, it’s probably time for an engine rebuild. This basic engine kit contains sleeves, pistons & rings, pins, and an overhaul gasket set—the core components you need to get that orange machine breathing like new again. Engine bearings must be ordered separately, so you can choose exactly what condition your crank and rods need.
What You’re Getting
- Fresh cylinder sleeves that restore proper bore dimensions and seal out blow-by
- New pistons and rings engineered to handle the demands of farm work
- Wrist pins and related hardware for smooth piston operation
- Complete overhaul gasket set to seal up every joint and surface
- Tru-Power quality that matches or exceeds OEM specifications
Built for Real Farm Work
This kit is designed for 4-cylinder gas engines with 138 CID (3-3/8 inch standard bore) or 149 CID (3-1/2 inch standard bore), with 3-9/16 inch overbore supplied. These engines powered many of the popular Allis Chalmers utility and row-crop tractors that are still earning their keep on farms today, handling everything from cultivating to hay work.
Made to Last
Tru-Power has been making engine rebuild kits for decades, and they understand what it takes to survive under a tractor hood. The cylinder sleeves are precision-made to restore proper compression, while the pistons and rings are built to handle the heat and pressure of hard farm work without premature wear.
Good to Know
This is a basic kit, which means you’ll need to order main and rod bearings separately based on what your crank measurements tell you. That’s actually a good thing—it lets you get exactly the right bearing clearances instead of guessing. Most rebuilders appreciate having that control over the final tolerances.
