Description
When your 8N or NAA tractor starts burning oil or losing compression, nine times out of ten it’s the piston rings that have given up the ghost. You’ll notice blue smoke out the exhaust, oil consumption going through the roof, and that familiar loss of power that tells you it’s time to dig into the engine. This individual piston ring gets your classic Ford tractor back to running the way it should—sealing combustion pressure where it belongs and keeping oil in the crankcase.
What You’re Getting
- Single replacement ring designed specifically for Ford’s reliable 120 cubic inch flathead engine
- Quality cast iron construction that handles the heat and pressure cycles of farm work
- Proper tension and fit to restore compression and reduce oil consumption
- TISCO manufacturing for dependable performance you can count on
Built for Real Farm Work
This ring fits the workhorse engines found in Ford 8N tractors from 1948-1953 and NAA models from 1953-1955. These tractors earned their reputation doing everything from cultivating row crops and mowing hay to running PTOs for feed mills and sawmills. Whether you’re restoring a classic 8N for weekend projects or keeping an NAA running for daily chores, this ring helps maintain the reliable power these engines are known for.
Made to Last
Ford’s flathead four-cylinder was built tough, and this replacement ring matches that durability. The cast iron material withstands the constant expansion and contraction that comes with engine heat cycles, while maintaining proper sealing against the cylinder wall. It’s designed to handle the steady, long-running operation that farm tractors demand.
Good to Know
This is sold as an individual ring, so you’ll want to measure your pistons and order what you need for your particular rebuild. Most folks doing a proper overhaul will replace all rings at once, but sometimes you just need one to finish up a job. Check your cylinder bore condition before installation—worn cylinders may need attention before new rings will seal properly.
