The disk stack repair insert can comprise a first replacement disk segment defining a first groove pattern comprising first grooves; and a second replacement disk segment defining a second groove pattern comprising second grooves, the first replacement disk segment coupled to the second replacement disk segment, wherein the first groove pattern and the second groove pattern define a fluid passageway therebetween. ## Claims ### Claim 1 A repaired disk stack comprising: a disk stack comprising a plurality of original disks joined together in a stacked configuration, the disk stack defining an outer surface defining an outer width and an inner surface defining an inner width that is less than the outer width, a first fluid passageway formed between a pair of adjacent original disks, an insert opening formed laterally through the disk stack from the outer surface to the inner surface; and a disk stack repair insert positioned in the insert opening, the disk stack repair insert comprising a plurality of replacement disk segments, a second fluid passageway formed between a pair of adjacent replacement disk segments. ### Claim 2 (depends on 1) The repaired disk stack of claim 1, wherein: a first one of the pair of adjacent replacement disk segments defines a first groove pattern; a second one of the pair of adjacent replacement disk segments defines a second groove pattern; and the first groove pattern confronts the second groove pattern to define the second fluid passageway. ### Claim 3 (depends on 1) The repaired disk stack of claim 1, wherein: the first fluid passageway extends from an inner surface of the disk stack to an outer surface of the disk stack; the second fluid passageway extends from an inner insert surface of the disk stack repair insert to an outer insert surface of the disk stack repair insert; fluid is configured to flow through the first fluid passageway from the inner surface to the outer surface; and fluid is configured to flow through the second fluid passageway from the inner insert surface to the outer insert surface. ### Claim 4 (depends on 1) The repaired disk stack of claim 1, wherein: the disk stack comprises a pair of solid opposing boundary sidewalls that do not intersect the first fluid passageway; each of the replacement disk segments defines a pair of solid opposing edges that do not intersect the second fluid passageway; and each of the solid opposing edges of the of the replacement disk segments abuts a corresponding one of the solid opposing boundary sidewalls of the disk stack. ### Claim 5 (depends on 1) The repaired disk stack of claim 1, wherein the disk stack repair insert fits seamlessly within the insert opening and is sealed with the disk stack by welding. ### Claim 6 (depends on 1) The repaired disk stack of claim 1, wherein the disk stack is a substantially cylindrical disk stack, the original disks are substantially annular original disks, and the disk stack repair insert is a substantially arcuate disk stack repair insert. ### Claim 7 (depends on 1) The repaired disk stack of claim 1, wherein: each of the original disks defines an original disk bore; the original disk bores define an elongated disk stack inner bore through a center of the disk stack; and a disk stack axis extends centrally through the disk stack inner bore. ### Claim 8 (depends on 7) The repaired disk stack of claim 7, further comprising a plug movably positioned within the disk stack inner bore. ### Claim 9 (depends on 7) The repaired disk stack of claim 7, wherein: an inner insert surface of the disk stack repair insert extends radially inward from an inner surface of the disk stack; and an outer insert surface of the disk stack repair insert extends radially outward from an outer surface of the disk stack. ### Claim 10 A repaired disk stack comprising: a disk stack comprising a plurality of original disks joined together in a stacked configuration, a first fluid passageway formed between a pair of adjacent original disks, an insert opening formed through the disk stack; and a disk stack repair insert positioned in the insert opening, the disk stack repair insert comprising a plurality of replacement disk segments, a second fluid passageway formed between a pair of adjacent replacement disk segments; wherein: a first one of the pair of adjacent replacement disk segments defines a first groove pattern; a second one of the pair of adjacent replacement disk segments defines a second groove pattern; and the first groove pattern confronts the second groove pattern to define the second fluid passageway. ### Claim 11 A repaired disk stack comprising: a disk stack comprising a plurality of original disks joined together in a stacked configuration, a first fluid passageway formed between a pair of adjacent original disks, an insert opening formed through the disk stack; and a disk stack repair insert positioned in the insert opening, the disk stack repair insert comprising a plurality of replacement disk segments, a second fluid passageway formed between a pair of adjacent replacement disk segments; wherein: the disk stack comprises a pair of solid opposing boundary sidewalls that do not intersect the first fluid passageway; each of the replacement disk segments defines a pair of solid opposing edges that do not intersect the second fluid passageway; and each of the solid opposing edges of the of the replacement disk segments abuts a corresponding one of the solid opposing boundary sidewalls of the disk stack. ### Claim 12 A repaired disk stack comprising: a disk stack comprising a plurality of original disks joined together in a stacked configuration, a first fluid passageway formed between a pair of adjacent original disks, an insert opening formed through the disk stack; and a disk stack repair insert positioned in the insert opening, the disk stack repair insert comprising a plurality of replacement disk segments, a second fluid passageway formed between a pair of adjacent replacement disk segments; wherein: each of the original disks defines an original disk bore; the original disk bores define an elongated disk stack inner bore through a center of the disk stack; a disk stack axis extends centrally through the disk stack inner bore; and the repaired disk stack further comprises a plug movably positioned within the disk stack inner bore. ### Claim 13 A repaired disk stack comprising: a disk stack comprising a plurality of original disks joined together in a stacked configuration, a first fluid passageway formed between a pair of adjacent original disks, an insert opening formed through the disk stack; and a disk stack repair insert positioned in the insert opening, the disk stack repair insert comprising a plurality of replacement disk segments, a second fluid passageway formed between a pair of adjacent replacement disk segments; wherein: each of the original disks defines an original disk bore; the original disk bores define an elongated disk stack inner bore through a center of the disk stack; a disk stack axis extends centrally through the disk stack inner bore; an inner insert surface of the disk stack repair insert extends radially inward from an inner surface of the disk stack; and an outer insert surface of the disk stack repair insert extends radially outward from an outer surface of the disk stack.
