Product Overview
A four-injector service set for selected John Deere diesel engine families. John Deere uses different pencil-injector calibrations across naturally aspirated and turbocharged engine codes, so the engine suffix and original injector number are more important than displacement alone.
Uneven combustion, difficult cold starts, haze/smoke, injector knock and poor power can develop as nozzles wear or stick. Replacing injectors should follow fuel-quality checks and, where applicable, pop-pressure/calibration requirements.
Key Features & Performance
- Meters and atomizes fuel for consistent cylinder combustion.
- Relevant to hard-start, smoke, rough-running and weak-cylinder diagnosis.
- Engine code and injector reference are critical fitment checks.
Specifications & Reference Numbers
- Quantity: 4 injectors
Before You Order
Verify the exact engine code and the number marked on an original injector. Do not choose solely by “3029/4039/4045/6059/6068” displacement family.
