How to replace injector nozzles for your John Deere tractor?
Tools: Vice grips, diesel, solvent, toothbrush, wrench
Preparation
Identify the location of the injector nozzles to be replaced on your John Deere tractor and ensure the area is clean. It’s best 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 prepared for diesel to drip from the bottom of the injector when the nut is loosened. So it is wise to 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 inspect for damage. Clean the nozzle sealing surface on the injector body and check 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. Clean the threads of the entire fixing nut and injector thoroughly.
Injector nozzle replacement
Ensure compatibility whether you purchase OEM or aftermarket injector nozzles.
Carefully keep the needle inside the new nozzle during unpacking.
Clean the nozzle and needle with a light oil solution, ensuring free movement of the needle inside the nozzle.
Align the new nozzle with the relevant holes and positioning pins during installation. Carefully place the fixing nut on the nozzle and tighten it, avoiding contact with the nozzle tip.
Important: There may be some gap between the nozzle and the body, which is normal due to spring tension in the nozzle needle.
