they are very ez to split, remove the jugs, remove the stator and clutch cover, pull the clutch and all the hardware, remove the flywheels and stator and unscrew the screws on the top of the case and fill the halfs over and remove the nuts on the bottom, use a rubber mallet to wack the cases and they should come apart.
