A compressor may include a shell and a housing fixed within the shell. A compression mechanism may be supported by the housing and may include an orbiting scroll member and a non-orbiting scroll member that are meshingly engaged to form a series of compression pockets. A retaining assembly may include an axial retention member and a rotational retention member, each of which is engaged with the non-orbiting scroll member to limit axial translation and rotation of the non-orbiting scroll member relative to the housing.
