a cup support mandrel disposed to position on a distal end of the tool, the cup support mandrel comprising an internally threaded bearing end configured to form a seat for receiving a bearing, the bearing configured to translate the rotational movement applied to the drive member into a pressing motion on the cup support mandrel, the cup support mandrel further comprising a gasket end, the gasket end comprising a gasket for gripping and retaining the injector cup; and a bridge configured to help segregate the tool from the cylinder head, the bridge comprising a pair of bridge supports for adjustably regulating the elevation of the tool. ## Claims ### Claim 1 A tool for manipulating an injector cup in relation to a cylinder head, the tool comprising: a drive member disposed to extend from a proximal end of the tool, the drive member configured to rotatably manipulate the tool; a cup support mandrel disposed to position on a distal end of the tool, the cup support mandrel comprising a bearing end, the bearing end configured to form a seat for receiving a ball bearing, the ball bearing configured to translate the rotational movement of the drive member into a pressing motion on the cup support mandrel, the cup support mandrel further comprising a gasket end, the gasket end comprising a gasket for grip and retention; and a bridge disposed approximately between the drive member and the cup support mandrel, the bridge configured to elevate the tool, the bridge comprising a pair of bridge supports for adjustably regulating the elevation of the tool above the cylinder head. ### Claim 2 (depends on 1) The tool of claim 1, wherein the drive member comprises a bolt. ### Claim 3 (depends on 1) The tool of claim 1, wherein the drive member is disposed in generally perpendicular relationship with the bridge. ### Claim 4 (depends on 1) The tool of claim 1, further including a drive member head disposed to join with the drive member, the drive member head configured to enable rotation of the drive member. ### Claim 5 (depends on 1) The tool of claim 1, wherein the drive member head has a generally hexagonal shape. ### Claim 6 (depends on 1) The tool of claim 1, wherein the cup support mandrel has a generally cylindrical shape. ### Claim 7 (depends on 1) The tool of claim 1, wherein the bearing end is internally threaded. ### Claim 8 (depends on 1) The tool of claim 1, further including a bearing sleeve configured to at least partially encapsulate the bearing for stabilizing positioning of the bearing. ### Claim 9 (depends on 1) The tool of claim 1, wherein the gasket comprises an O-ring. ### Claim 10 (depends on 1) The tool of claim 1, further including a nut and at least one washer configured to help adjust position and distance between the drive member and the cup support mandrel. ### Claim 11 (depends on 10) The tool of claim 10, wherein the nut is internally threaded. ### Claim 12 (depends on 11) The tool of claim 11, wherein the at least one washer comprises a pair of lock washers. ### Claim 13 (depends on 1) The tool of claim 1, wherein the bridge comprises a bottom wall, a top wall spaced-apart from the bottom wall and multiple sidewalls extending between the bottom wall and the top wall. ### Claim 14 (depends on 1) The tool of claim 1, wherein the bridge comprises a drive member aperture disposed to pass through a cross sectional region of the bridge, the drive member aperture configured to enable at least partial passage of the drive member. ### Claim 15 (depends on 1) The tool of claim 1, wherein the bridge comprises a plurality of threaded apertures disposed to pass through a cross sectional region of the bridge, the plurality of threaded apertures configured to enable at least partial passage of the pair of bridge supports. ### Claim 16 A tool for manipulating an injector cup in relation to a cylinder head, the tool comprising: a drive member disposed to extend from a proximal end of the tool, the drive member configured to rotatably manipulate the tool, the drive member comprising a drive member head configured to provide a surface for rotating the drive member; a cup support mandrel disposed to position on a distal end of the tool, the cup support mandrel comprising a bearing end, the bearing end configured to form a seat for receiving a ball bearing, the ball bearing configured to translate the rotational movement of the drive member into a pressing motion on the cup support mandrel, the cup support mandrel further comprising a gasket end, the gasket end comprising a gasket; a bearing sleeve disposed on the bearing end, the bearing sleeve configured to at least partially encapsulate the ball bearing for stabilizing the ball bearing; a nut and at least one washer configured to help adjust position and distance between the drive member and the cup support mandrel; and a bridge disposed approximately between the drive member and the cup support mandrel, the bridge configured to elevate the tool, the bridge comprising a pair of bridge supports for adjustably regulating the elevation of the tool above the cylinder head, the pair of bridge supports comprising a pair of bolts, the bridge further comprising a plurality of threaded apertures disposed to pass through a cross sectional region of the bridge, the plurality of threaded apertures configured to enable at least partial passage of the pair of bridge supports, the bridge further comprising a drive member aperture disposed to pass through a cross sectional region of the bridge, the drive member aperture configured to enable at least partial passage of the drive member. ### Claim 17 (depends on 16) The tool of claim 16, wherein the drive member comprises a bolt. ### Claim 18 (depends on 16) The tool of claim 16, wherein the drive member is disposed in generally perpendicular relationship with the bridge. ### Claim 19 A method for manipulating an injector cup in relation to a cylinder head with a tool, the method comprising: providing an injector cup pressing tool for controllable pressing of an injector cup into a cylinder head; retaining, within a gasket, the injector cup in a cup support mandrel; centering the injector cup over the cylinder head; restricting contact between a drive member and the cylinder head with a bridge; manipulating a pair of bridge supports for adjusting the elevation of the tool relative to the cylinder head; rotating the drive member in a direction conducive to installing or removing the injector cup; and translating, through a ball bearing, the rotational movement of the drive member into a pressing force on the cup support mandrel.
