Description
When your old International Harvester starts smoking, burning oil, or just doesn’t have the power it once had, it’s time for a complete engine rebuild. This overhaul kit gives you everything you need to bring that 123 cubic inch gas engine back to life. Whether it’s your dependable Super A cultivating or your Super C running the hay baler, this kit gets you back to full power without the guesswork of hunting down individual parts.
What You’re Getting
- Complete rebuild solution—sleeves, pistons, rings, valves, gaskets, bearings, and all the small parts you’ll need
- Stepped-head pistons designed for the overbore option if your cylinders need extra cleanup
- Fresh valves, springs, and guides to get your engine breathing right again
- Quality rod and main bearings to handle the load these tractors were built for
- Complete gasket set seals everything up tight from oil pan to head
Built for Real Farm Work
This kit fits the workhorses that built American farms—the 100 and 200 series tractors, plus the Super A-1 and Super AV-1 models (before serial number 310300) and Super C series. These were the tractors doing row work, cultivating, mowing, and powering everything from post hole diggers to feed grinders back when farms were smaller and every tractor had to do it all.
Made to Last
Tru Power has been rebuilding farm engines for decades, and this kit includes all the quality components you’d expect. The sleeves are built to handle the heat cycles and loads these engines see, while the gaskets use materials that won’t give up after a few seasons of hard work.
Good to Know
This is a complete teardown and rebuild project—plan on having the tractor down for a while and make sure you’ve got a clean workspace. The stepped-head pistons give you flexibility to clean up worn cylinders with an overbore if needed. If you’re not comfortable with a full engine rebuild, this is definitely a job for an experienced mechanic who knows these old Internationals.
