There was a post from Lulzbot support on here that said it was beyond the scope of the average person.
“Disassembling the hexagon hot end (for nozzle swaps, etc) is something we cannot recommend either. We use a torque wrench to 30in lbs of torque, and a high temp thread locker rated to 2100f. If these guidelines are followed on re-assembly (tools we can’t expect customers to have) leaking will occur. This can not only affect quality, but the automatic bed leveling process as well.”
The rest of the thread made it sound really easy though, and you seem to back that claim up. It also sounds like the thread locker isn’t needed for the nozzle itself. I assume I’d just need something like this and other than that it’s pretty straightforward.
