heat round the main bearing on fly side an locating dowel at bottom of gearbox ,nxt to filler hole .on really stubborn cases you can use a punch on end of dowel to break the gasket seal ,but only til cases just crack apart a pencil line width .an also put clutch an flywheel nuts back on flush to end of crank an using a soft hammer wallop end of crank to move it side to side an crack gasket seal .it helps to hold kickstart 1/4 turn down aswell to stop quadrant catching on cases an run heat along gasket line to encourage it to give up its grip. its just patience , heat ,wallop , more heat ,wallop ,etc ,they will split .

if its got wheels n makes a noise I wanna play with it, skateboards included coz "skate-punks rule",
Just tried again, tapped all around the casings where they meet with a rubber mallet, heated up the flywheel bearing and still won't split! How much heat can you use on the casings? I don't want to damage the casings or crank if possible.
