.22lr Hammer Screw removal

[MiniCoyote]

Hello Everyone,

I am having a difficult time trying to remove the hammer screw.  I understand it is a left thread screw (righty loosy, lefty tighty) but cannot get the thing to budge.  Even soaking in Liquid Wrench, heat, hammer taps cannot get this screw un-threaded.  For those who have disassembled their .22lr, was there difficulty with this as well?

Hi mini
I have had some apart.
Never any problems.

Welcome to the asylum.

  Welcome and heat it up with a pencil point soldering gun .

Glad I sent mine back to NAA for hammer work.  I didn't know it is a LH thread.  I would have surely boogered it up good.

Helllo Everyone,

Finally got the darn thing undone.  The last time it was opened was for when I had sent it back to NAA to fix a broken main string.  Not sure if thread-locker was used by their technicians.  However, the new hammer is installed and works as expected. 

OV-1D, I heated it up and then soaked the threaded-side with Liquid Wrench while tapping the screw head between each re-application of LW.  After about an hour of soak time (and destroying two flat-head bits) I finally got it loose.

To anybody wishing to take one of these guns apart themselves prepare for a mechanical challenge.  It wasn't too difficult but did take time without having any specialized tools.

I find no problems getting one apart. It is the getting them back together that is problem.
