5801507557 NOZZLE ( GENUINE )

The 5801507557 Fuel Injector Nozzle is a CNH Genuine high-precision component designed for the Case 570 SV and Case 570 ST backhoe loaders.

This nozzle controls the fine atomization and delivery of diesel fuel into the combustion chamber, ensuring efficient burning, strong engine power, lower fuel consumption, and reduced emissions.

A high-quality injector nozzle is essential for proper engine performance, especially for machines operating under heavy-duty or continuous workloads.

Function of the Fuel Injector Nozzle

The injector nozzle is responsible for:

• Atomizing diesel fuel into fine particles

• Ensuring optimal fuel spray pattern

• Delivering fuel at the correct pressure and timing

• Maintaining stable combustion

• Improving engine power and throttle response

• Reducing black smoke and excess fuel burn

A worn or damaged nozzle will cause incomplete combustion and engine performance issues.

Key Features & Benefits

• CNH Genuine Part — perfect fit and OEM-level precision

• High-pressure resistant construction

• Accurate spray pattern for efficient fuel burning

• Improves engine power, torque, and acceleration

• Reduces fuel consumption

• Minimizes black smoke and exhaust emissions

• Durable materials for long service life

� Symptoms of a Faulty Injector Nozzle

Replace the nozzle if you notice:

• Hard starting or delayed ignition

• Excessive black smoke from the exhaust

• Engine shaking or rough idling

• Loss of power or slow acceleration
