Hi guys
Do i need a special tool 07733-0020001?
or is there other way to remove the fly wheel?

Hieu.

Hi Hieu,
I built something out of 2 strips of metal and a couple of bolts to hold the flywheel in place, then all you need is a large bolt to screw in and pull/ push the flywheel off.
If you're local you're welcome to borrow it. There's probably someone close who has already done the same.
Just let us know where you are, I'm sure someone will come forward.

The Special tool is an M20 x 1.5 bolt. Remove the bolt thats in the middle of the flywheel and screw that one in to pop it off.

The bolts a bit of an odd thread.. not that uncommon but you may struggle to find one at your local store.

If you can't get them rick O sell them for a pound or two.
