This fuel injector is a direct replacement unit designed for John Deere Engine. It delivers a precise atomized fuel spray into the combustion chamber for efficient burning. When an injector fails, the affected cylinder runs lean — or doesn’t fire at all — which puts extra stress on the remaining injectors and can damage the catalytic converter over time.

Signs You Need a Replacement

If your equipment is showing any of these symptoms, the injectors & nozzle may be the cause:

• Black or gray exhaust smoke — especially noticeable under load or acceleration
• Rough or uneven idle — the engine shakes or vibrates at low RPM
• Engine misfire or hesitation — stumbling when you step on the throttle
• Poor fuel economy — filling up more often for the same work
• Knocking or nailing sound — metallic noise from the engine under load
• Fuel smell in engine oil — diesel leaking past the injector seat into the crankcase

Replace as a Set

Replacing injectors as a set is the standard practice. Mixing old and new injectors creates uneven spray patterns — the new unit works harder and burns out faster. On multi-cylinder engines, a single failing injector can reduce total output by 20 to 30 percent. When you pull the old injectors, inspect the seats and copper sealing washers. If the seats are pitted or the washers are crushed, replace them before installing the new units.

Frequently Asked Questions

Will this fit my John Deere 4045?
Yes. This part is designed to fit the John Deere 4045, 6068, 120D, 130G among other models listed in the compatibility table above. Verify your specific model and engine code before ordering to ensure the correct fit.

Can I cross-reference RE546783 with RE531210?
Yes. Both RE546783 and RE531210 are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions. This replacement fits all applications listed for either number.

My vehicle is a 5000 model — is it covered?
The compatibility range for this part includes 5000-6320. The 5000 model year falls within this range, but you should still verify the engine code and body type match. Mid-year production changes sometimes mean two vehicles from the same model year use different parts.

What are the common failure signs on a John Deere engine?
On John Deere engines, watch for black exhaust smoke under load, rough idle, misfire codes (P0300 series), and loss of power. A single failing injector can reduce engine output by up to 25%. If you notice fuel in the engine oil, the injector seat seal is likely compromised — replace it immediately to prevent crankcase contamination.
