Removing Spindle Head on Maho MH-400E

How to remove spindle head on Maho MH-400E very easy with no heavy lifting. I did the same on my older mill an Anayak a few years ago when I retrofitted it. I need to get inside the head and remove the angular drive that connects to the orginal gearbox, It makes an anoying sound when I drive the head directly on the spindle with an timing belt and an AC servo motor. There will soon be an video for the servo motor mounting and testing.
