Coldworking sleeve removal tools and methods
A sleeve removal tool for removing a split sleeve embedded in a structure includes a main rod, a nose cap, a housing, and a nut. The main rod includes a main threaded portion and a neck portion. The nose cap is configured to removably couple to the neck portion of the main rod and to removably couple to a flare of the split sleeve embedded in the structure. The housing includes a non-marking foot. The housing is configured to at least partially surround the main rod. The nut is configured to be threaded onto the main threaded portion of the main rod, wherein threading the nut onto the main threaded portion of the main rod forces the housing against the structure and forces the main rod away from the structure, thereby removing the split sleeve from the structure.
1 . A sleeve removal tool for removing a split sleeve embedded in a structure, the sleeve removal tool comprising:
a main rod comprising a main threaded portion and a neck portion;
a nose cap configured to:
removably couple to the neck portion of the main rod; and
removably couple to a flare of the split sleeve embedded in the structure;
a housing comprising a non-marking foot, the housing configured to at least partially surround the main rod; and
a nut configured to be threaded onto the main threaded portion of the main rod, wherein threading the nut onto the main threaded portion of the main rod forces the housing against the structure and forces the main rod away from the structure, thereby removing the split sleeve from the structure.
2 . The sleeve removal tool of claim 1 , wherein the housing is tubular in shape.
3 . The sleeve removal tool of claim 1 , further comprising a washer that is installed around the main threaded portion of the main rod between the nut and the housing.
4 . The sleeve removal tool of claim 1 , further comprising a pin that is configured to be removably coupled to the neck portion of the main rod, the pin comprising a diameter that permits the pin to be inserted into the split sleeve.
5 . The sleeve removal tool of claim 1 , wherein the main rod comprises an anti-rotation aperture on an end of the main rod opposite the neck portion.
6 . The sleeve removal tool of claim 1 , wherein the nose cap comprises a groove configured to accept the flare of the split sleeve.
7 . The sleeve removal tool of claim 1 , wherein:
the main threaded portion of the main rod comprises a first diameter; and
the neck portion of the main rod comprises a second diameter that is smaller than the first diameter.
8 . A sleeve removal tool for removing a split sleeve embedded in a structure, the sleeve removal tool comprising:
a main rod;
a nose cap configured to:
removably couple to the main rod; and
removably couple to a flare of the split sleeve embedded in the structure;
a housing configured to at least partially surround the main rod; and
a nut configured to be threaded onto the main rod, wherein threading the nut onto the main rod forces the housing against the structure and forces the main rod away from the structure, thereby removing the split sleeve from the structure.
9 . The sleeve removal tool of claim 8 , wherein the housing is tubular in shape.
10 . The sleeve removal tool of claim 8 , further comprising a washer that is installed around the main rod between the nut and the housing.
11 . The sleeve removal tool of claim 8 , further comprising a pin that is configured to be removably coupled to the main rod, the pin comprising a diameter that permits the pin to be inserted into the split sleeve.
12 . The sleeve removal tool of claim 8 , wherein the main rod comprises an anti-rotation aperture on an end of the main rod opposite the nose cap.
13 . The sleeve removal tool of claim 12 , wherein the anti-rotation aperture comprises an aperture for an allen wrench.
14 . The sleeve removal tool of claim 8 , wherein the nose cap comprises a groove configured to accept the flare of the split sleeve.
