ABSTRACT:
A scissor-type jack is used to separate the yoke that holds a drill boot. The jack or separator is expanded to bend the yoke outward thereby allowing the drill to disengage from the yoke. A replacement boot or the repaired boot is installed in the yoke and the separator contracted until the boot reengages the yoke. The separator expands and contracts responsive to the rotation of a hexagonal head that can be rotated by a conventional socket using a ratchet.
