The JDG10631 Electronic Injector Sleeve Puller is a precision service tool designed for the removal of injector sleeves (cups) from John Deere 4045 and 6068 diesel engines, including 9.0L platforms equipped with Electronic Unit Injectors (EUI). This tool is engineered to safely extract injector sleeves that are often carbon-seized, corrosion-bound, or tightly press-fit into the cylinder head.
Injector sleeves are critical to engine operation, providing a sealed interface between the injector and cylinder head to maintain fuel delivery integrity and coolant isolation. Improper removal methods—such as prying or using incorrect pullers—can damage the cylinder head bore, resulting in coolant leaks, poor injector sealing, and costly repairs. The JDG10631 puller is specifically designed to grip and extract sleeves with controlled force, minimizing the risk of damage to surrounding components.
This professional-grade tool allows technicians to perform sleeve removal with precision, repeatability, and efficiency, making it an essential addition to any agricultural, industrial, or heavy-duty diesel service operation working on John Deere engines.

Why It Matters
Injector sleeves must maintain a proper seal between fuel and coolant systems while ensuring accurate injector positioning. Damage during removal can lead to:
-
Coolant contamination of fuel
-
Fuel leakage into the cooling system
-
Loss of injector sealing and performance
-
Expensive cylinder head replacement
The JDG10631 Injector Sleeve Puller provides the correct tool for safe, efficient sleeve removal—helping technicians maintain engine reliability, performance, and longevity.
