ABSTRACT

A seal removal jig is used for removing a seal portion from a casing of a
rotary machine. The seal removal jig includes a jig body pushed up from below
in a vertical direction by a jack, and a jig fixing portion that detachably
fixes the jig body to an end surface of the seal portion. The jig body
includes a jig contact portion that is contactable with an end surface of an
upper half seal portion or a lower half seal portion in a circumferential
direction about an axis of the rotary machine; and a jig protrusion protruding
outward in a radial direction with respect to the jig contact portion and
pushed up from below in the vertical direction by the jack. The ratio of a
first distance to an outside diameter of the upper half seal portion or the
lower half seal portion is 0.01 or more and 0.1 or less.
