I did straighten the washer.
The nut is still tight.

Washer straightened? Nuts partially approved?

I could not remove the clutch hub today.
First, I fixed the piston pin to loose the nut, when I turned ratchet something was loosen.
But when I continue to turn the ratchet the clutch center hub rotates together.
Do I need to fix the clutch center hub to loose the nut?

I need the service jig like the picture?

It's locking the nut.
" . . Do I need to make it straight when I loose the clutch net? . . " Yes

Please see the arrows in the picture.

You mean clutch basket ribbing?
