Injector cup pressing tools

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.

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.
