special tools?

Hey guys I'm going to start rebuilding a yz400f and was wondering if I needed to get special tools like a flywheel puller or crank case separator. Or is there a way to do it without special tools.

Yes, you need a flywheel puller.


I use a 3-prong steering wheel puller to split cases.

You can get a pretty nice case splitter from tusk for a low price, you will need a flywheel puller, and a clutch holder is also nice to have.
