Removal Tool (Threaded Body & Mandrel) Cummins C&J Copper Sleeve

This Removal Tooling Set is designed for removing copper injector sleeves from Cummins C&J and Sm/V engine series. This set includes a specific mandrel and a split tool body with buttress threads. When the mandrel is pressed into the tool body, it expands to grip the sleeve, allowing for mechanical extraction using a press. The complete set consists of one Mandrel and one Tool Body.

This Removal Tool Set (Mandrel & Threaded Body) Cummins C&J and Sm/V Copper Sleeve Removal Tools provides the necessary components for the initial stage of servicing Cummins C&J and Sm/V engine series – the removal of old injector sleeves. This tool set is specifically engineered to extract copper injector sleeves from these engine types efficiently and effectively.

The complete set consists of a tapered mandrel and a removal tool body with buttress threads, designed to work together:

1. The appropriate mandrel (specific to the C&J and Small/V series) is positioned inside the used injector sleeve with its tapered end facing downwards.
2. The removal tool body (also specific to the C&J series and featuring buttress threads) is then brought into the sleeve, aligning it so that the tapered end of the mandrel is inside the tool body.
3. Downward force is applied to the mandrel, typically using a press. As the tapered end of the mandrel is pressed further into the tool body, it causes the buttress threads on the tool body to expand outwards.
4. This expansion creates a strong and secure grip on the inner surface of the copper injector sleeve.
5. Continued downward pressure on the mandrel then effectively pulls the injector sleeve, now tightly held by the expanded tool body, out of the engine casting. The use of a press is highly recommended to provide the necessary controlled and consistent force for this extraction process.

This Removal Tool Set (Mandrel & Threaded Body) is an essential tool for preparing Cummins C&J and Small/V engine series for either injector seat repair or the installation of new injector sleeves. Its mechanical design, utilizing the tapered mandrel for expansion and the buttress threads for grip, ensures reliable removal of the old copper sleeves.
