A method for repairing a gear (2) having a number of damaged teeth (4, 4′, 4″), wherein the method comprises the step of removing material from the gear (2) hereby providing a pocket structure (28, 28′, 28″, 28′″), wherein said material includes at least one damaged tooth (4, 4′). Said method further comprises the step of providing a segment (12, 12′, 12″, 12′″) to be inserted into the pocket structure (28, 28′, 28″, 28′″), wherein the segment (12, 12′, 12″, 12′″) has a geometry that fits the geometry of the pocket structure (28, 28′, 28″, 28′″). The method comprises the step of radially inserting the segment (12, 12′, 12″, 12′″) into the pocket structure (28, 28′, 28″, 28′″) and attaching radially extending attachment structures (60, 60′) through at least a portion (18, 18′) of the segment (12, 12′, 12″, 12′″) and further into at least a portion (32, 32′) of the underlying structure (64) of the gear (2).
