Description
When it’s time for a major engine rebuild on your Allis Chalmers, you want to do it right the first time. Nothing’s more frustrating than tearing into your engine for a rebuild only to find you’re missing critical parts halfway through the job. This complete overhaul kit takes the guesswork out of rebuilding your 226 cubic inch gas engine—everything you need comes in one box.
What You’re Getting
- Complete valve train rebuild with new intake and exhaust valves, springs, guides, and keys
- Fresh cylinder sleeves with matching pistons and rings for like-new compression
- Full gasket set that seals everything up tight and keeps oil where it belongs
- Cam bearings included so your camshaft runs smooth and quiet
- Standard 4-inch bore with 4-1/8 inch overbore option gives you flexibility for different rebuild scenarios
Built for Real Farm Work
This kit fits the 170 Series and D17 Series Allis Chalmers tractors—reliable orange machines that have been earning their keep on farms for decades. These 4-cylinder gas engines were built to handle everything from field work to loader duty, and with this rebuild kit, yours will be ready for many more seasons of dependable service.
Made to Last
Every component in this Tru-Power kit meets or exceeds original equipment standards. The sleeves are precision-machined for proper cylinder wall finish, the pistons are matched to the rings for optimal seal, and the valve train components are built to handle the heat and stress of hard work. This isn’t a budget rebuild—it’s a quality restoration.
Good to Know
This is a late crank application kit, so make sure your engine matches before ordering. The kit comes with everything for the top end and cylinders, but you’ll want to check your main and rod bearings separately. Having fresh oil pump and water pump seals on hand isn’t a bad idea either when you’re this deep into the engine.
