Starter clutch dissassemble is under control ))
Some advises to those who afraid to do it yourself - just dont be. The only thing you need is to follow the manual and videos to know how it can be done.
Also you will need a special removal tool. I had no luck with handmade one (smaller one on image), all applied force had been bending the bolts and rotor won't came out.
Instead, with a more serious puller, I took off the rotor in a second, just by applying the force by hand.
It is possible only when the main screw has such a big thread.
