Abstract
An integrated drive generator includes a housing having generator. Center and input housing portions are secured to one another. The center housing portion is sealed relative to the generator input housing portion with seal plates. A hydraulic unit is mounted to the center housing portion. The center housing portion includes first and second parallel surfaces. A machined surface is parallel to and recessed into one of the first and second surfaces in an area of the hydraulic unit. A method of assembling an integrated drive generator includes the steps of providing a bore in a center housing portion, pressing a bearing liner into the bore, with a portion of the bearing liner extending proud of a surface of the center plate, and machining the surface around and adjacent to the bearing liner to provide a machined surface parallel to the surface.
