How to disassemble print head/gantry (A5)?

I've been trying to get my A5 working for years but kept putting it on the back burner. Recently I've had a bit more free time and have been putting in the effort to fix this thing but everything keeps going wrong. I broke the screw that goes into the block trying to unscrew it and it's too short to use pliers and I can't get it out with a power drill and easy-out bits. I'm thinking I need to remove the whole head part and put in some penetrating oil to get the screw out. Any thoughts, tips, helpful advice? Thank you for your time.

Do not forget to haet it up before!! There might be bits of molten plastic in threads, whose are holding it really tight when cold
For removal you have to unscrew Z motors, remove thread screws, linear guides and then you can manipulate with X axis freely. remove all cables and you have free hotend block. This is how I replaced bearings on X axis(for bottom bearing you need this procedure, as it is enclosed inside block.Top, bigger bearing is screw fixed by metal block)
