Both, the instruction states to remove the crankshaft bolt but the illustration shows the crankshaft pully puller in use. The same holding tool is used to keep the crankshaft from turning.
The diagrams are a little different in comparing your posts 7 & 11. In your post 11, it appears the pulley (for the accessory belt) has already been removed. Isn’t that the timing belt pulley I see, with the ridges (cogs) on it? I don’t recall having to remove that pulley.
