The problem: Tool sticking in spindle on tool changes, manual or M6
I heard air leaking at the top of the drawbar, so I removed the sheet metal spindle cover. I found air leaking as shown in the picture.

So now I suspect one of the o-rings in the piston plate assembly. The thing is, I seem to recall that removing the inside plate is not fun. Something about needing to bleed the system after reassembly. And the two counterbores for the screws that attach it to the top are peened so that removing the screws is difficult. It's like a subtle "Danger: Do not enter!" sign. Is this going to be a big pain or do I just go for it?
