John Deere diesel injectors and injection pumps

John Deere tractors are built to work hard, but injectors wear and injection pumps eventually need replacing or rebuilding. We supply fuel injectors, injection pumps and related fuel system parts for a wide range of John Deere tractor models.

Fuel system signs on a John Deere tractor

• Hard starting, especially on cold mornings
• Black or white smoke from the exhaust
• Uneven idle or a shaking engine
• Fuel leaking at the injection pump
• A drop in power under load

Have your tractor model and serial number ready, plus the part number from the old injector or pump if you can read it.

John Deere parts we supply

• Diesel fuel injectors and nozzles
• Diesel injection pumps and repair parts
• Lift pumps, fuel lines, seals and fittings

Common questions

How do I find the right injector for my John Deere?

Give us the tractor model, year and serial number. If the old injector has a number stamped on it, read that out as well. We match the part before you order.

Should I replace all the injectors at once?

Usually yes. A single new injector next to old worn ones can leave cylinders unbalanced, so a matched set tends to run smoother.

Can you supply injection pump repair parts?

Yes. Depending on the model, a rebuild kit or seals may be enough. Call us and we will tell you whether a repair or a replacement pump makes more sense.
