Question about a sketch

Hello
I'm making a part, and I'm stuck in a place where I have a dimension, but I don't understand what the dimension defines it. It is the one with a radius of 85.

Hello

For me, R of 0.85 between the fixing lugs and the main cylinder (Ø74).
It seems that the 0 was not noted...

Kind regards

I have to say, that's a big 85 radius there!
