Well so much for the notches in the harmonic balancer. Useless they would seem. I can feel the bolt I have to remove, but its closer to crank then the notches allow to get at. If the notches were maybe a half inch deeper it would work. So not sure which half-brained engineer designed this thing, but getting the water pump out is back to being a total pain.
So back together it goes for now with deep loathing for german engineers.
I did do some more searching online too, indeed the balancer must come out on the 560.
