Built for Real Farm Work
This piston fits the 172 CID diesel engines found in Ford 801, 901, and 4000 series tractors—machines that earned their reputation pulling plows, running PTOs, and handling the heavy lifting on farms across the country. These are some of the most dependable diesel tractors Ford ever built, and they’re still putting in honest work today.
Made to Last
Diesel engines run hotter and generate more pressure than their gas counterparts, so pistons take a real beating. This TISCO piston is engineered to handle the combustion pressures and thermal cycling that come with diesel operation. The 5-ring design provides superior sealing to keep compression where it belongs and oil where it should stay.
Good to Know
This is a rebuild-quality piston, so make sure your cylinder bore is within spec before installation. If you’re doing a complete rebuild, you’ll want to check connecting rod condition and measure cylinder taper while you’re in there. A good shop manual and proper measuring tools make all the difference in getting the job done right.
