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