If it is like a superdream then there are three things to remove.
1 - The damper rod bolt. As above at the bottom of the forks there will be a 6mm AF ccap head to undo. Do this before removing the spring but after draining the oil or the whole thing turns.
2 - The spring. after removing the stantion and draining there will be a 14?mm af allen piece in the top of the forks. undo this gently as it will spring a little once undone. it is a very fine thread so will take a while to undo. It should come easly so don't force it.
3 - Dust cap, retainer and oil seal. Pull off the outer dust cap, this will reveal the oil seal at retainer. The retainer is usually a type od circlip, so using circlip pliers remove this gently. Once removed extend the forks violently in your hands, bashing the stantion against the oil seal. Repeat this until the oil seal, and fork stantion pop out.
Hope this makes sence.
