Abstract
A seal compression tool is disposed at a readily accessible location externally of the cylindrical casing of a gas turbine engine, and has a camming surface thereon effective to interengage and axially shift the turbine nozzle of the gas turbine engine. Such axial shifting uniformly and controllably compresses a static seal carried between the turbine nozzle and the casing at a remote, relatively inaccessible location inside the gas turbine engine.
