description

RE546776 common rail fuel injector is the core fuel injection component of John Deere 8350 4045T diesel power system. It precisely controls injection timing, fuel delivery, injection rate and atomization quality under high common rail pressure, meeting fuel supply requirements of 4045T engine under frequent heavy load changes. The injector body is forged from high-strength alloy steel with excellent pressure resistance and wear resistance. Core components including nozzle, needle valve and control valve are ultra-precisely machined to micron-level clearance, effectively preventing oil leakage and valve sticking faults. Every finished injector passes full bench tests including idle & full load injection quantity and sealing inspection, ensuring excellent injection accuracy and consistent batch performance. Direct plug-and-play replacement without modifying engine fuel pipeline. It solves common failures such as weak power, unstable idle speed, black smoke and high fuel consumption, suitable for tractor maintenance and engine overhaul.

advantage

• **Agricultural Heavy Load Custom Calibration**
Professional calibration for John Deere 4045T engine farm working conditions, perfectly adapts to frequent start-stop, heavy traction and variable load operations such as plowing and harvesting, with stable fuel injection and no power attenuation.
• **Micron-level Precision Atomization Technology**
Adopts imported 6-hole precision nozzle, uniform and fine fuel atomization. It solves the problems of insufficient combustion, black smoke and carbon deposition of agricultural machinery engines, effectively improves combustion efficiency, increases power by 5%-8%, and reduces comprehensive fuel consumption.
• **Wear-resistant and Durable Core Structure**
The injector body is integrally forged with high-strength alloy, and the needle valve and control valve are processed with ultra-precision micron technology. It has strong pressure resistance and anti-clogging performance, effectively avoids common faults such as oil leakage, valve sticking and poor fuel injection, and greatly extends the service life.
• **Strict Factory Bench Testing**
Each injector undergoes idle speed, rated load, overload fuel injection volume and sealing leakage full-item testing. The fuel injection error is controlled within 1%, with stable batch consistency and strong interchangeability.
• **Plug-and-Play High Cost Performance**
Fully compliant with OEM original size and installation standards, no pipeline modification, no debugging required for direct replacement. Effectively solves common faults such as weak power, unstable idle speed, high fuel consumption and exhaust blue smoke, reducing equipment maintenance costs.

FAQ 

Q1: What equipment and engines is the RE546776 injector suitable for?
A1: It is specially adapted to John Deere 8350 tractor, matching 4045T diesel engine. It is fully interchangeable with 095000-6480/6481/6482, RE529149 and other models. Please confirm the engine model before installation to avoid mismatch.

Q2: What failures can this injector solve?
A2: It can effectively repair common faults of agricultural machinery engines, such as weak acceleration, unstable idle speed, difficult cold start, black smoke/blue smoke from exhaust, excessive fuel consumption and engine power drop.

Q3: Is coding and calibration required after installation?
A3: Factory pre-calibrated, plug and play without complicated coding. If multiple injectors are replaced at the same time or the ECU has historical fault codes, it is recommended to clear codes appropriately for better idle stability and fuel economy.
