Default Splitting the Crankcase Advise

So I'm going to split the crankcase on my 2000 600 to replace the crank bearings and seals. Any advise on tear down and reassembly? I figured if I don't try I'll never learn.

Not too hard. Just make sure you have a clutch puller and flywheel puller. You won't be able to split the case without taking the flywheel and stator off.

dont pry on the case halfs, unless there are pry spots (gaps, that stick out that dont effect the mating surface at all, meant for prying on) If there are none you can tap on the halves, with a rubber or plastic mallet. make sure to grease the inner lip of the seals before re assembling. Also be sure to make sure that the pins line up with the crankcase halves.

I have the clutch puller and fly wheel puller so I should be good there. How hard are the bearings to replace. Also any good advise on putting back together.

The outer bearings wouldn't be to bad if you have a press. You need special tools to do the center bearings as you need to press the crank apart, and orientate it when putting it back together.

I'm getting there but anyone have a good easy idea to get the studs out of the top of the case? I'm decided to have the the case and jugs "decked" just smoothed out a little.

If you deck the case you could/will run into a bearing crush issue. So make sure before you put it together.

I changed the base gaskets last year and one was not sitting right. I had a small leak in the cylinder and I figured if I have everything opened up and the local shop has time why not get a good fit. Plus it will be free. So why not get th top of the case and the bottom of the jugs cleaned up.
