1st sorry for my poor and mistakefull English,but I'm a self teaching people.
Well,I'll try to tell you about crankshaft splitting,but some things need to be clear before. This shaft is a composite one,so your work is both side needed.
You can use a normal pin bench press to push out the connecting pin ( which is one only for all crankshaft) from the each side,living the pin and all the rest were it is.
Different if you need to disassemble totally the item.
In any case are enough two a 10 or 12 mm rectangular plates to hold the part when you press the pin out.
The best is warm by hot air the pin area during operation.
Much more difficult is after recomposition,make the perfect centering of alla the crankshaft,which is a very handly experience work.
That the reason why I suggest You to ask to a workshop were they do this work,expecially because a very little difference....make the difference.
But in any casa write me about the problem and step by step I will try to help you.
Try to take a look about how the item is composed here were a free spare parts catalog is.
