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.
When you're dealing with low compression, burning oil, or that tell-tale blue smoke coming from the exhaust, worn pistons are usually the culprit. A failing piston assembly doesn't just hurt power—it can damage other engine components and leave you stranded in the middle of harvest. This Iveco NEF turbo piston assembly gets your tractor engine back to full strength with proper compression and clean combustion. What You're Getting Complete piston assembly designed for turbocharged NEF engines—handles the extra heat and pressure Standard bore sizing that maintains original engine specs and performance OEM-quality construction that meets the same standards as your original parts Direct replacement—no machine work or modifications needed for installation Built to handle the high compression ratios of modern diesel engines Built for Real Farm Work This piston assembly fits a wide range of New Holland tractors from the compact T4000 series utility models up through the mid-size T5000 and T6000 row-crop machines, plus Case IH JX and Maxxum series tractors.

Made to Last NEF engines are known for their durability, and this piston assembly is built to the same standards. The turbo-rated design handles the increased cylinder pressures and temperatures that come with forced induction. Quality metallurgy and precision manufacturing ensure proper ring sealing and long service life, even under the demanding conditions of agricultural work. Good to Know This is a major engine repair that requires complete disassembly of the top end. You'll need the matching piston rings (part Q8094845) which are sold separately. Make sure to check cylinder bore condition and have it honed if needed. Proper torque specs and ring gap measurements are critical for a successful rebuild. If you're not comfortable with engine work, this is definitely a job for your mechanic.
