It has oil inside (usually they put way oil in those). I opened the lubrication hole yesterday and stuck an awl in.

It is hefty, but I can handle it. I screwed a lifting eye to it and can lift it with my shop crane or chain hoist or just push it from the shop cart onto the milling table. > Homing it might be done with a flag to pass thru the gap of an opto- > interrupter, then set on an index pulse from the motor.
