Description
When your tractor’s engine starts burning oil or you notice blue smoke at startup, it’s usually the piston rings telling you they’ve had enough. This 0.40mm oversize ring set is designed specifically for NEF Iveco engines, giving you the perfect solution when your cylinders have been bored out during an engine rebuild.
What You’re Getting
- Complete ring set with all compression and oil control rings for one cylinder
- 0.40mm oversize to fit freshly bored cylinders perfectly
- Non-turbo specification rings built to handle the demands of naturally aspirated NEF engines
- Quality construction that seals tight and handles the heat cycles of farm work
Built for Real Farm Work
These rings are made for the workhorses in your fleet – from utility tractors handling daily chores to mid-size machines pulling implements through tough conditions. The NEF engine family powers everything from compact tractors to mid-range row crop machines, and this ring set keeps them running strong season after season.
Made to Last
NEF engines are known for their reliability, and these rings are built to match that reputation. The materials and tolerances are designed to handle the temperature swings, dust, and constant operation that come with farm life. You’ll get the compression you need and the oil control that keeps your engine clean.
Good to Know
This is a 0.40mm oversize set, so make sure your machine shop has bored your cylinders to the right specification. Most engine rebuilders know the NEF platform well, but it’s always worth double-checking the bore size before ordering. Each set handles one cylinder, so order accordingly for your engine configuration.
