Does anyone know of a detailed description or video about how to change the MM castle gate? I'm particularly stuck about how to remove the front face of the castle. I got the whole gate/motor assembly loose from the bottom, and removed that moat trough. But the assembly can't pull straight down because there's that metal flap that goes right through the gate opening. It seems like I need to remove the castle front so the the whole assembly can move forward around the metal flap.
Looking at the bottom of the playfield, it looks like there's a screw coming down under the left side of the castle, but I don't see any way to get to the screw head at the top.
Or maybe I'm going about this all wrong. Any help would be appreciated!
