yeah, splitting the case may involve special tools often, like a crankshaft puller, clutch puller, flywheel puller, even crankcase splitter (cause the ball bearings are a press fit into crankcase) but the job can still sometimes get done without busting the crankcase or something.. there's some models of saw that have threaded holes on one side that are used with regular screws to "push" crankcase apart.. but most times just had to spend a few hours with a soft mallet, blocks of wood, propane torch, and dry fuel & oil tanks (or a fire extinguisher handy) so unless you want to invest in the tools needed (which Ive seen can cost as much as $250 for something you could build easily if you have a welder and some machinist skills) or the time (could take several patient hours moving things by thousandths of an inch at a time), you may find it a challenge not worth taking.. (not to mention the cost of new crank assembly and new jug kit which if you go OEM will cost you more than just buying a whole new saw)
