ABSTRACT:
A universal clamp for use in sealing the surface ports of an engine part possessing a fluid circulating jacket such as a cylinder head so that the part may be subjected to fluid pressure testing, which includes, a mounting member adapted to be positioned in an engine cylinder head bolt hole, consisting of an actuation element which extends through a fixed sleeve portion and is threadedly interconnected with a wedging sleeve portion for axial movement with respect to the fixed sleeve so as to engage the wedging and fixed portions and force them into wedging engagement with a portion of the wall of the bolt hole, thereby securing the clamp. Slotted arms are slidably and rotatably mounted on the mounting member so as to be radially adjustable to allow sealing of ports positioned at varying distances from the mounting member. Screw members threadedly interconnected with the arm members secure plug or other sealing structures thereby sealing the ports.
