Good evening, I’m about to replace the ZR on a MX5 NB, now the belt disc has to go down, but I can’t get off the central screw on the KW… the 4 M6 screws just came down, but now this screw has to go down. I’ve already tried with a impact screw, but he probably didn’t have enough power.. then I tried with a counter holder & violence, and there’s one of the rods (the counter holder) broken off and the screw didn’t move I Ch will try it with a stronger impact wrench, but does someone have another idea? Except as suggested in other threads with a self-made counter holder that you attach to the 4 M& screws… because if you use force on the 4 M6 screws like that, they certainly don’t have a good PS: the pulley looks like in the attachment (in the photo 2 of the 4 nuts are still on it, now they are out) (the mother must definitely down, since the Simmerring also to be replaced) Grus
