Description
When your Ford tractor’s engine starts using oil or lacks the compression it used to have, worn pistons are often the culprit. This 3.9 inch standard bore piston is part of the complete rebuild solution for Ford’s 172 cubic inch engines, giving you the tight seal you need to get back to full power and efficiency in the field.
What You’re Getting
- Standard 3.9 inch bore diameter that matches original factory specifications
- Three compression rings for optimal cylinder seal and oil control
- Includes wrist pin and locks for a complete installation
- Quality TISCO construction built to handle the demands of farm work
- Direct replacement that fits like the original piston
Built for Real Farm Work
This piston fits Ford’s 172 cubic inch, 4-cylinder engines with 3.9 inch bore found in 800, 801, 900, 901, and early 4000 series tractors from 1963-1964. These are the utility tractors that handle everything from loader work around the barn to running rotary cutters and finishing mowers – machines that need reliable power you can count on season after season.
Made to Last
Farm engines work harder than most, dealing with dust, temperature swings, and long hours under load. This piston is manufactured to OEM standards with proper ring groove clearances and durable materials that stand up to the heat and pressure of continuous operation. The three-ring design provides excellent compression while controlling oil consumption.
Good to Know
This is a standard bore piston, so your cylinders need to be in good shape or freshly bored to standard size. If you’re doing a complete rebuild, it’s commonly paired with EAF6055D sleeves and EAF6149A rings in complete overhaul kits. Check your cylinder bore measurements before ordering – if the bores are worn beyond standard limits, you’ll need an oversized piston or sleeve kit instead.
