Hi Robert, thanks for the reply.
I got it half way with the heat, but can't go any further.
Any advice on lube?

Be careful when powering up the heater when it isn't connected to the thermocouple, the software will not stop heating it if it does not know that it actually gets hot.
Tighten two M6 nuts onto the thread. To form a locknut.
Then put a soldering iron tip against the aluminium block, and heat it up.
Grip the "locknut" assembly and screw out the brass piece.
To do this you really need a small vice to hold the thing in the jaws. Hold the thing at an angle on the
corners or the heat from the iron will just go straight into the vice.
Once you suceed, apply copper grease to the threads before re-assembly. This will prevent it
sticking again, although the grease will smell for a few hours of printing as it burns off, leaving
just the copper particles in the gap.

I just finished replacing my hotend last night. I couldn't get my thermocouple or heater out of the old block while cold, when hot they both slid out of there easily. So, maybe try heating it up (with the heater halfway in it'll still heat up) and try again.
