The JDG10014 Injector Sleeve Removal Tool is a John Deere Servicegard tool designed for removing electronic injector sleeves from the cylinder head on John Deere diesel engines.
Injector sleeves on these engines are installed with an interference fit and are exposed to heat cycling, coolant contact, and combustion forces. Over time, this can cause sleeves to seize in place, making removal difficult without proper tooling.
The JDG10014 is engineered to securely engage the sleeve and apply controlled pulling force, allowing technicians to extract the sleeve cleanly without damaging the cylinder head bore.
This is critical because the sleeve bore must remain:
- Smooth and undamaged
- Properly sized for new sleeve installation
- Free of scoring or distortion
Improper removal methods—such as prying or chiseling—can lead to:
- Bore damage or scoring
- Improper fit of replacement sleeves
- Coolant or fuel sealing failures after reassembly
The JDG10014 ensures sleeves are removed:
- Straight and evenly from the bore
- Without damaging sealing surfaces
- Ready for accurate installation of new sleeves

Why It Matters
Injector sleeve removal is one of the most damage-sensitive steps in cylinder head service.
Common issues from improper removal include:
- Scored or oversized bores
- Poor sealing of new sleeves
- Repeat repairs due to leaks
The JDG10014 ensures sleeves are removed correctly, preserving the integrity of the cylinder head and allowing for reliable sleeve replacement.
