Abstract
A tapered sleeve bolt removal tool for removing a tapered sleeve bolt includes a stop sleeve configured to be coupled to a threaded end of a bolt of the tapered sleeve bolt. The stop sleeve has a stop shoulder configured to abut against a bottom of a sleeve of the tapered sleeve bolt. The stop sleeve has a lateral dimension less than or equal to a lateral dimension of the sleeve to allow the stop sleeve to be removed through an opening with the bolt and the sleeve. A bolt extractor having a bolt engagement feature is configured to engage an extraction shoulder of the bolt. The bolt extractor is pulled in an extraction direction to pull the bolt, the stop sleeve and the sleeve to simultaneously remove the sleeve and the bolt from the opening in the component.
