You would remove flywheel and casing bolts and use case splitter or 3 legged puller to separate engine cases. Take lots of pictures for assembly reference. Best to source a repair manual before any further disassembly. You can easily cause a lot of damage in motor by using improper disassembly methods. Good luck to you.
