Mk3s+ hotend mantainance/extruder disassembly?
I am in the process of upgrading my mk3s extruder to the mk3s+. I have discovered that my hotend is a mess from badly (not) torqued nozzle. I want to continue the assembly, but go back when I'm done to try to salvage the hotend (it printed fine before disassembly).
Is there a guide to getting the hotend that isn't just full extruder disassembly? It seems like Prusa changed the design to allow this, but I'm failing to find a particular article/guide.
E3D guide is good
The E3D hotend assembly guide is very good. Pay careful to the bit about screwing in the nozzle flush, backing it out to the desired < 1mm gap, THEN hand-tightening the heatbreak up against the nozzle. The important bit is that, when properly tightened, it should be impossible to tighten the nozzle flush up against the block.

As Bobstro said, be careful. This diagram illustrates on problem in edition to not getting nozzle against the heatbreak.
