    alternating heating..and cooling may break the bond    (btw did you try soaking a while  with a release agent or simple WD-40)

    try heat on the cam  (if using a torch stop the flames!!!  ………. then  freeze the crankshaft with a can of keyboard spray cleaner from the Dollar store… held upside down  the contents with blast out and  freeze anything !

    if no result ……………. heat up the shaft and freeze the cam

     

    lots of theory on heating or freezing  circular shapes…like a cam ….. does it expand or shink if heated… or freezed  🙂
