    Abstract: coating a silicon sealant to a predetermined uniform thickness over the thermal insulation of the motor case and nozzle assembly; fastening a plurality of spacing bolts having threaded ends into the corresponding threaded spacing holes of the nozzle flange; aligning the nozzle assembly with the motor case such that an end of the after dome flange of the motor case is positioned over the first O-ring; maintaining the interior of the motor case at a primary vacuum pressure to move voids from the silicon sealant; applying a secondary vacuum pressure higher than the primary vacuum pressure to the interior of the motor case to move the nozzle assembly toward the motor case; and fastening the high strength bolts into the threaded holes of the motor case.
