Rebuilding the front forks on my '84 200M. Decided to take pics and try and provide some info on the process for those who may need it. Will update as I progress.
First, I recommend you download the factory service manual and print out the section on the front end.
Once the forks are on the bench, you need to loosen the Allen bolt in the bottom of the fork. This is what keeps the damper and fork assembly together. Mine were.stuck and corroded, before I touched them I soaked them for about 2 or 3 weeks in Hagens brew (50/50 mix of diesel fuel or ATF and Acetone). A small impact carefully applied with a 6mm allen socket is useful to break them loose. Loosen but do not remove.
Next step is to depress the inner fork cap and remove the circlip. This will allow the inner springs to come out. This is most easily accomplished by the use of a hydraulic press to compress the spring **JUST ENOUGH** to where the clip is visible. Sometimes some penetrating oil can help free the cap up, they get stuck with grime and age. The clip can then be removed with a pick.
Once the cap is off, the springs can easily be removed. I suggest a clean drain pan be used to dump the springs into so as not to loose pieces. Pay attention to the thrust washer between the 2 springs.
Picture below shows all the components on the bench,, and tools required for the job.
Updates to follow as I progress......
