Mauser K98k trigger group

[Litwa]

Hi, I want to remove a trigger group from a mauser reciever to replace it with a new one and its completely stuck, tried pushing the pin out with a hammer and a nail or pointy metal object to no avail. Is there any way to remove a part that's so rusted and stuck without drilling it? And if I have to drill it, do I have to use a special drillbit or an ordinary one would work? And I can see (it's hard to see on the pics but its there) a broken spring inside the trigger group so I would like not to damage it more. I would really appreaciate your advice on this matter. Pics attached show trigger group in question but I wasn't sure what to photograph. Thanks in advance for any help!
Best regards,
Litwa

Why do you want to put a new part on a rusted and pitted rifle? It's hardly going to improve its looks is it?

I don't really care about looks I just want to have a working trigger, and the replacement one is not in the best shape either. I just want the mechanisms to function.

I've removed these a few times in the past on some of the project K98s I used to have. A hammer and pin always did the trick, but they were not in relic condition like this. I know this may seem very obvious, but have you used any type of lubricating oil? I would completely saturate the pin in something like WD40 and then give it another go.

I assume you're trying to fit this barrel & receiver to a stock, and for display purposes you want a more intact trigger. Personally, I would leave a relic like this alone, and display it as it sits. But it is your call.

Sadly for me, I'm pretty sure I used half a can of WD40 trying to get this trigger off. I'll try putting it in a vice and trying with more force, and also which side do I try to push it out on? The one with the bolt stop or the other side?

Hello,

Try using fire, making it warm/hot and then squeezing it out...

[Litwa]

Do you mean boiling it or putting it in an acual fire?

[TheGoon]

Heat it up with a torch if that's possible then give it a good hit when it's really hot, if that doesn't work use a cobalt drill bit to drill it out

[Litwa]

Welp, I've tried boiling it then spraying wd40 and trying to get it out and now I've tried heating it up with a torch to no avail maybe I'll figure out something else in the future but for now I won't drill it
