An apparatus for servicing an engine cylinder head of an internal combustion engine includes a mounting portion adapted to be removably attached to the engine cylinder head. The apparatus additionally includes a support portion for radially supporting the cam sprocket. The support portion is generally cylindrical in shape and adapted to align with the cam shaft. The apparatus is intended to maintain the radial position of a cam sprocket during removal of the cam shaft. The mounting portion preferably includes a pair of apertures adapted to align with a pair of apertures in the cylinder head. Further, the mounting portion is generally planar and the support portion extends substantially parallel to a plane defined by the mounting portion. A method of servicing an engine cylinder head having a cam sprocket mounted for rotation on a cam shaft includes the general steps of providing a sprocket mounting member, removably attaching the sprocket mounting member to the engine cylinder head, radially supporting the cam sprocket on the sprocket mounting member, removing the cam shaft from the engine cylinder head and maintaining a radial position of the cam sprocket.
