Abstract: A method of aligning and duplicating alignment includes welding a washer over a larger opening in a hinge once in an aligned position relative to a vehicle door. The door is mounted into an alignment fixture and the hinges are installed over threaded studs extending from the door. The washer is placed onto the threaded stud and tightened against the hinge, covering the larger opening in the hinge. The larger opening in the hinge allows movement of the hinge relative to the door for alignment. The washer defines an opening with a smaller opening sized to provide relatively little clearance for the threaded stud, and thereby maintain alignment between the door and hinge. The washer is permanently attached by a welding operation to allow duplication of door hinge alignment during reassembly.

Abstract: A pressure vessel having a removable closure head in a high radiation environment is closed by placing the closure head having a flange over and spaced from the flange of a pressure vessel body containing fissile material. The closure studs are installed in closure stud holes of the pressure vessel body flange. Transition nut members of hydraulic nut assemblies are threaded onto the closure studs. Hydraulic hoses are connected between the hydraulic nut assemblies and a pressure source. The pressure source simultaneously pressurizes the hydraulic nut assemblies to simultaneously apply a uniform force to the closure studs sufficient to seat the spaced apart closure head flange on the pressure vessel body flange and to elongate the closure studs. The hydraulic nut assemblies are locked in place over the closure head flange while the force is applied to the closure studs and the closure studs are elongated.
