Z-motor removal

[johnbrophy]

I have a prt alpha in desperate need of new pinions and though the x and y motors were a breeze i can't see a way to remove the z motor without fully disassembling the z car. There are holes in the beam but they dont align with the heads of the bolts i need to get to. Any advice would be greatly appreciated

there are holes covered by stickers on the back of the z plate the router or spindle is attached to. you have to move the z up or down to align the holes with the bolt heads can't remember what size allen they use. there are three of them.
