Description

When your Massey Ferguson or other diesel tractor starts running rough, smoking, or losing power, there’s a good chance it’s time to look at the fuel injectors. These precision components are the heart of your diesel’s fuel system, and when they wear out or get clogged, everything suffers. This replacement injector nozzle gets your Perkins AD3.152 or AD4.203 engine back to spraying fuel the way it should.

What You’re Getting

Precision-machined nozzle that delivers the exact fuel spray pattern your engine needs
Direct replacement for worn or damaged original nozzles—no modifications required
Built to handle the high pressures and temperatures of diesel injection systems
Proper hole size and spray angle to match your engine’s combustion chamber design

Built for Real Farm Work

This nozzle fits the reliable Perkins diesel engines that powered thousands of Massey Ferguson tractors through the decades. Whether you’re running a classic MF 135 for hay work, a 765 for heavy field operations, or industrial equipment with these proven engines, this is the same quality component that kept these machines running strong from the factory.

Made to Last

Injector nozzles take a beating from constant high-pressure fuel flow and combustion heat. This one’s manufactured to original specifications with hardened steel construction that resists wear and corrosion. The precise internal passages maintain proper fuel atomization even after years of hard use.

Good to Know

Installing injector nozzles requires removing and disassembling the injector assembly—it’s a job for someone comfortable with diesel fuel systems. If you’re doing the work yourself, make sure everything’s spotless before reassembly, and consider replacing the injector seals while you’re at it. A clean fuel system means longer nozzle life.
