Abstract
An assembly for a wind turbine, comprising a shaft extending within a main shaft housing. A radially outer portion of the shaft includes at least one engagement formation. A retention mechanism is moveable radially between a radially inward position in which the retention mechanism can engage the at least one engagement formation, such that rotation of the shaft is constrained, and a radially outward position in which the retention mechanism cannot engage the engagement formation, thereby allowing rotation of the shaft.
