Olsson Block installation woes -- old nozzle won't loosen

Posted (edited) · Olsson Block installation woes -- old nozzle won't loosen

I recently purchased an Olsson Block for my UM2 (and am really excited about it!) but in disassembling my printer for the new nozzle, I ran into trouble with this step: https://ultimaker.com/en/support/18016-disassembling-the-hot-end

Specifically, the hot end did not drop down. It is very much stuck to the isolator. I have turned it as much as I can, but am now leaving marks and deformations on the isolator by trying to turn it more.

What can I do?

Also, as a side note, I was looking for a PTFE ring to remove, and it appears there isn't one: I can't find it anywhere. Is that cause for concern?

    Latest UM2 had a spare stainless steel coupler as a spare part with them. That is probably the easiest way. Otherwise try to unscrew it HOT and some people also used WD40. If everything goes wrong you may get a spare stainless steel coupler from your Ultimaker dealer/distributor or maybe more easily from 3dSolex.

    Has the isolator moved up from the metal plate? As in, is there a space between the bottom metal plate of the head and the ring with holes in it? If so, you need to wiggle the hotend around so that it sinks down again.

    That happened to me as well, try wiggling the spring while loosing it. Also be careful when pulling the temperature sensor because it's really sensitive and you'll end up changing it if you pull it hard.
