Proper fuel atomization is critical for diesel engine power, fuel efficiency, and emissions compliance. For the John Deere 4045 engine family, the RE529118 fuel injector GP (also referenced as 529118 injector AS) is a precision-engineered component that delivers the correct fuel quantity and spray pattern to each cylinder. Whether you are troubleshooting misfires, excessive smoke, or poor fuel economy, this OEM-grade injector assembly restores engine performance to factory specifications.
Engineered for John Deere 4045 PowerTech™ Engines
The RE529118 fuel injector is a unit injector (mechanical or electronic depending on the 4045 variant) that combines the pumping and injection functions into a single assembly. It is designed to withstand extreme pressures (up to 20,000+ PSI) and precise timing control. This injector GP ensures complete combustion, reduced emissions, and smooth operation across all load ranges – from idle to full throttle.

OEM Calibration: Each injector AS meets John Deere flow and pressure specifications – no need for additional coding on most mechanical 4045 engines.
-
Durable Construction: High-grade steel and hardened internals resist wear from low-sulfur diesel and biodiesel blends.
-
Direct Replacement: Plug-and-play fit with correct sealing washers and O-rings included (verify with your kit).
Symptoms of Failing Fuel Injectors
-
Rough idle or engine misfire
-
Excessive white, black, or blue smoke
-
Loss of power under load
-
Increased fuel consumption
-
Fuel knock or abnormal combustion noise
-
Hard starting or extended cranking
-
Oil dilution (fuel in engine oil)
Installation Recommendations
-
Replace all injectors as a set for balanced performance (or at least cylinders on the same bank).
-
Use new sealing washers and O-rings (often sold separately or in a kit).
-
Clean injector bores thoroughly before installation.
-
Torque injector hold-down bolts to John Deere specifications (typically 45-55 Nm).
-
Prime fuel system and check for leaks after installation.
-
On electronic 4045 variants, perform injector coding if required (consult service manual).
