Hi all just started stripping my engine to replace a damaged first gear and inspect the mains etc. Cylinder off, clutch casings off, flywheel removed along with all the casings bolts and the casings have opened up slightly. Is it possible to split the engine without taking all the clutch side to pieces. The casings have already opened up about 1mm pretty easy but obviously I don't want to force it, I'm awaiting delivery of a cluch hub holder to remove the clutch basket side, but it seems it might be possible to pop one half of the casings away and leave the crank still in the bearing on clutch side cheers. 

I'll answer my own question. no the clutch basket must come off because its attached to the gearbox main axle . For anybody considering splitting cases you will definitely need an impact wrench.
