sorry dude, wrong. leave the tranny on the clutch side. you want to pull the primary drive gear ,but leave the clutch and kickstart idler gear installed. this will keep the tranny in place inside the case.
pull the left side (ignition side) off then pull the crank out of the right side. but this will make it a little difficult to get the crank bearing out of the clutch side half, because the shift forks and drum might wanna fall out while you're pounding out the bearing. also, you prob wanna get a full seal kit. the countershaft seal will most likely get torn up during the split.
as for splitting the cases, it's SO easy w/ the right tools, but if you don't wanna buy them, you can get the cases split w/ a rubber mallet, though it'll be a little harder to get the crank out of the second half.....but it would be pretty hard to try to get the crank back into the new bearings. you can try sweating it in, or try fabbing a puller w/ some allthread and a pvc or conduit pipe. just gotta figger out a way to attach the allthread to the crank threads.
