The ATC W93658900700 Injector Cup Removal & Installation Tool is a precision-engineered service tool designed for safe and efficient removal and installation of injector cups in Detroit Diesel DD5 engines. Injector cups (also known as injector sleeves) are critical components that seal the interface between the fuel injector and the cylinder head, ensuring proper fuel delivery, combustion efficiency, and coolant isolation.
During service, injector cups can become carbon-seized, corroded, or tightly press-fit into the cylinder head. Attempting removal with improper tools can result in head damage, distorted cups, or sealing surface failure, leading to coolant leaks or injector misalignment. This tool is specifically designed to eliminate those risks by providing positive engagement and controlled extraction force.
The ATC W93658900700 utilizes a 2 part expanding jaw design that securely grips the injector cup from within, allowing technicians to remove or install the cup without slipping or damaging the bore. This same design ensures proper alignment during installation, helping seat the new cup evenly and to the correct depth.
Built for professional use, this tool is ideal for diesel repair facilities, fleet maintenance operations, and engine rebuild shops servicing Detroit Diesel DD5 platforms.
