It appears that the W107 uses a different tool than the Klann. Trying to force that shaft into the spring will allow you to get the plates engaged. Then, when you tighten the shaft, the spring, plates, and shaft all come out together.
Now, if you are successful in removing it with the Klann clone, I certainly would not use it to put the spring back in, because you'll never get the shaft out from inside the spring.
