How to Replace Injector Nozzles for Your John Deere Tractor?
Tools Required
- Vice grips
- Diesel
- Solvent
- Toothbrush
- Wrench
Preparation
Identify the location of the injector nozzles to be replaced on your John Deere tractor and make sure the area is clean. It's advisable to work on a metal workbench.
Removal
- After removing the injectors from the engine, clean them with a toothbrush and soak them in a lightweight solvent for cleaning.
- Use vice grips to secure the injector and carefully remove the nozzle and injector clamp nut. Handle the return oil nipples carefully to avoid bending or breaking them.
- Loosen the injector clamp nut using a 15mm wrench or deep socket. Be aware that diesel may drip from the bottom of the injector when the nut is loosened, so have tissues or towels ready for cleaning.
Cleaning and Inspection
- Use solvent and a toothbrush to clean carbon buildup around the nozzle fixing nut and check for damage.
- Clean the nozzle sealing surface on the injector body and inspect for any damage.
- Check the installed nozzle positioning pins for integrity.
- Remove the plastic cap at the injector inlet and blow air into the injector with an air hose. Immediately reinstall the protective cap after blowing air.
- Thoroughly clean the threads of the entire fixing nut and injector.
Injector Nozzle Replacement
- Whether you purchase OEM or aftermarket injector nozzles, ensure compatibility.
- When unpacking, carefully keep the needle inside the new nozzle.
- Clean the nozzle and needle with a light oil solution to ensure the needle can move freely inside the nozzle.
- During installation, align the new nozzle with the relevant holes and positioning pins. Carefully place the fixing nut on the nozzle and tighten it, avoiding contact with the nozzle tip.
- Note: There may be some gap between the nozzle and the body, which is normal due to the spring tension in the nozzle needle.
How Much Does a New Injector Nozzle Cost?
Depending on your equipment brand, type, and model, the price of a new aftermarket injector nozzle with OEM quality ranges from $10 to $460. These are the costs for a DIY replacement. If you've consulted repair companies, you'll notice the high labor costs. Check the injector nozzle catalog to find the parts you need.
