Its not the easiest of jobs, and some tooling is required, all is commercially available, but depends on your basic skills and facilities as they can be manufactured simply. Fork strip down topic is well documented on this forum.
The seal holders can be sourced in stainless for not much more the chromed steel, that the route I went.
The two tools required are a device for removing the seal holders, this is a hollow tube which fits over the fork stanchions and has two tangs to locate into the slots in the seal holders. The other tool is to aid assembly of the forks back into the steering yokes, this has a male thread to screw into the fork stanchions, people use an old fork top and weld some threaded rod to it. This tool can be substituted by the use of a round dowl, this is screwed into the stanchion thread. The bike needs to be lifted high at the front, tie some rope around the yokes and lift up via the yokes.
