The sleeve removal tools consist of two mandrels, each with tapered end, and a removal tool body with buttress threads at one end.
The mandrel is positioned up in the used sleeve with the tapered end down.
The removal tool body is brought up into the sleeve with the tapered end of the mandrel in the tool. As the mandrel is forced down, the buttressed threads on the tool expand and grab a hold on the sleeve, continue to press down on the mandrel and pull out the sleeve. The use of a press on the mandrel is recommended.
