Paddle Wheel Shaft / Hub RepairBack to
||American Classic Voyages|
The mated or contact areas between the shaft and hub on this steam boat paddle wheel would receive extreme wear from corrosive fretting. The wear was so severe that the metal was worn more than .125". The previous method of repair was to simply drive wedges between the shaft and hub in an effort to stabilize.
The complete repair areas were first roughened and cleaned using needle guns. All surface areas were then chemically cleaned using Cleaner Blend 300. The hubs were positioned on the shaft using wedges. The hub position was locked using a variety of positioning clamps. Titanium Putty was mixed and transferred into caulking guns. The mixed Titanium Putty was injected between the hub and shaft though injection port holes. Titanium Putty effectively filled all worn contact areas and voids. Titanium Putty has extremely high compressive strength (18,800 P.S.I.), and is non corrosive. An ideal solution for a unique problem saving thousands of dollars. This application is ABS documented and approved.
