Need help for a Maho 700 year of manufacture 1978.

I am looking for help dismantling a maho 700 with a damaged cnc controller with quite a few parts missing. It has a hydraulically activated spindle x,y,z axis drive. Since it is a salvage purchase which came with no documentation I would appreciate any help. I am stuck removing the x axis y axis box fixed to the right side of the table. Planning to drive all the directions using independent drives.
