Description
When your old TEF20’s engine starts showing its age with blue smoke, loss of power, or that telltale rattle of worn pistons, it’s time for a complete piston replacement. The Ferguson TEF20, often called the “Little Grey Fergie,” revolutionized farming in the 1940s and 50s with Harry Ferguson’s three-point hitch system. This complete piston assembly with rings brings your faithful workhorse back to its original smooth-running performance.
What You’re Getting

- Standard motor size for original bore specifications
- Quality construction designed to handle the demands of daily farm work
- Rings properly gapped and ready for installation
- Direct replacement that restores compression and power
Built for Real Farm Work
These 20-horsepower workhorses handled everything from plowing small fields to powering sawmills and hay balers. Your TEF20 might be running a bush hog, pulling a hay rake, or operating a PTO-driven piece of equipment around the farm. This piston assembly ensures your tractor keeps delivering reliable power for whatever job comes next.
Made to Last
This piston is built to the same specifications that made these tractors legendary for their durability. The included rings provide proper compression sealing while allowing the piston to move smoothly in the cylinder. Quality materials resist wear and maintain their seal through thousands of hours of operation.
Installation Notes
Engine work requires splitting the tractor and removing the engine, so plan accordingly. While you’re in there, it’s smart to check cylinder bore condition and consider having it honed if needed. Make sure to properly gap the rings and use proper assembly techniques – clean everything thoroughly and follow proper torque specifications. Consider replacing other engine seals and gaskets while you have access.
