Removal Tool (Threaded Body & Mandrel) Cummins 250, l-1- & M-11 Copper Sleeve

This Complete Removal Tool is specifically designed for removing copper injector sleeves from Cummins 250 series engines. This set includes a mandrel 415-6132-29 with a tapered end and a tool body 415-6132-51 with buttress threads. When used together with a press, the tool expands to grip the sleeve, allowing for its mechanical extraction.

The [415-6132-50] Complete Removal Tool is the designated assembly for the efficient and effective removal of copper injector sleeves from Cummins 250 series engines. This complete tool set comprises two essential components that work in tandem to extract the old sleeves:

• Mandrel 415-6132-29: This mandrel features a tapered end and is designed to be inserted into the used copper injector sleeve. It is also applicable to Cummins 220, L-10, and M-11 series engines.
• Tool Body 415-6132-29: This tool body is equipped with buttress threads at one end and is designed to slide over the mandrel. It is applicable to Cummins 250, L-10, M-11, and Small V series engines.

The removal process using this complete tool [415-6132-50] involves the following steps:

1. The tapered end of the mandrel 415-6132-29 is positioned inside the used copper injector sleeve.
2. The tool body 415-6132-29 is then brought up into the sleeve, so 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, the buttress threads on the tool body expand outwards, securely gripping the inner surface of the copper injector sleeve.
4. 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 strongly recommended to provide the necessary controlled and consistent force for this extraction process.

This Complete Removal Tool set is an indispensable tool for preparing Cummins 250 series engines for either injector seat repair or the installation of new injector sleeves. By providing both the gripping mandrel and the pulling tool body in one complete set, it ensures a reliable and effective method for removing old copper sleeves.

Note: This complete set consists of one Mandrel and one Tool Body.
