LTMX Crankcase Splitter

This purpose made tool features three legs that swivel independently. The legs are slotted to accept the bolts used to hold the tool to the crankcase whilst the pressure screw pushes on crank to ease the cases apart. Once split the tool will also push the crankshaft from the remaining crankcase. Perfect for all vertically split crankcase engines. 

Why risk damaging the cases with bodge methods especially as the cases and frame probably have matching numbers?
