Trilogy SF unscrewed Feedneck

[devilzcall]

So I'm still struggling with the feedneck on my Trilogy SF (non-pro), which I have read, and looks like it is attached via threads. However I can't get the thing to budge even when clamping it down in my vice.
I know the basic trilogies have fixed/plain feednecks, but the piece on my trilogy does look a bit different, and there is a visible separation between the bit that's pressed into the body and the stovepipe.
Even If I could get it loose I probably wouldn't find a replacement clamping Feedneck for those particular threads, but It drives me nuts that I can't find a single documented case of someone screwing the Feedneck off their Trilogy Pro or SF.

I can confirm with firsthand experience that Trilogy SFs do have threaded feednecks. It's actually a 2 piece feedneck, where there's a threaded adapter that goes into the body and then a cocker/timmy threaded feedneck goes on top of that. Here's a pneumatic assist pump I built using a Trilogy Competition SF a few years ago. Note that it has a CCM feedneck:




All of the SF bodies have threaded feednecks. None of the mechs (including the Pro) had threaded feednecks.

Heat it first. People replace these all the time, they use cocker/timmy threaded feednecks.
