Now I don't like disagreeing with people but the use of Loctite 660 or the older version found over here Loctite 601 can only be classed as a temporary running repair, because its main function is a retainer/bonder for close fitting cylindrical parts. very useful for keeping keys in keyways permanent fit for bearings and bushes in holes or housing and requiring a great deal of heat to break its bond. If used as a just an adhesive on the barrel hook its bond starts to break down at the open edges and a shim fitted this way will eventually fail sometimes very quickly.
