Abstract : A balance weight supported by a spring clip is inserted inside the low turbine shaft of a jet engine at the proper position and frictionally engages an inner bulkhead in the form of an 'anti-oval plug'. The clip is provided with a threaded opening to receive the threaded end of an elongated rod whereby the clip is inserted within the shaft and installed at the desired location after which the rod is unscrewed from the clip and withdrawn, leaving the weight in place on the anti-oval plug.
