If you cock the hammer in a model 62, how much rear travel can the trigger have when you then pull it? Mine seems to barely have enough room to move back, which causes releasing the hammer to be a bit of a challenge. If I fiddle with the trigger I am able to free the hammer, but that does not seem to be how it wanted to be fired.

Suggestions?
 
It sounds like something is blocking the trigger. Have you given the trigger group a thorough cleaning? Lots of crud can accumulate there. My 62 has a little less than1/4" between the trigger and the back of the guard but it is still plenty of movement to release the sear.
 
Kp321, I will tear it apart again to clean and let you know. With that said, how do you lock the hammer spring in the hammer rod to remove it? I know the rod has a hole like a M92 lever action, but while in the lever action rifle I can cock the hammer to slide the rod such the hole is in the "disassembly position" I do not seem to be able to do that in the M62, leading me to be aggressive with my punch. Putting it back I did use a strong paperclip in the hole.
 
Quick measurement but I must warn it is in mm: I measured the distance between the front of the trigger closest to the rear when hammer is cocked and then when I pull it as far back as I can (as if to release the hammer, which is not in the mood to do so). Both against the same vertical position in the trigger guard. The difference is 0.23mm.
 
Sounds like someone recut the engagement notch (sear) on your M62. You might have to replace the hammer.
 
How to know if the notch is boink? Here are the hammer and trigger from the only time I took the rifle that much apart:

Kp321, best way I can describe the trigger travel is this:

  1. At the hammer down position (fired), trigger has no freeplay. Right now trigger is some 2.5mm ahead of rear trigger guard (inside measurement).
  2. Start pulling hammer back.
  3. At the "safe" position, trigger moves a bit forward. It is a bit but very obvious. Now trigger moved forward so it is 4.8mm ahead of rear trigger guard (inside measurement as before).
  4. Bring hammer to fully cocked. Distance is now 3.8mm.
  5. Cock the hammer, so the above distance is now 2.5mm at fully cocked. But, hammer does nothing; it is not released or even move back a bit as it would in a revolver whose hammer is about to be released.
  6. I have very little hammer travel but if I pull it back to as far as it can go (you can't see it), the trigger resets back to the 3.8mm position.
  7. To fire I then have to push the back of the hammer forward while trigger is at the 2.5mm position. That will cause hammer to drop; trigger will not move and we are back to step 1.

Outside of what looks like file use on the hammer it is hard to get a perspective of the relationship between the hammer and the trigger without having another good set to compare this to. Look for example at your photo as it is showing the present engagement. Now imagine what would happen if one of the engaged lips breaks off. (particularly the one on the trigger) . Then someone recuts the notch to create a new engagement just like it was, but now the location has moved and the relationship of the hammer and trigger change, and the hammer is in a different location of travel when the two are engaged . That's what I think has happened in this case, and most like the trigger notch. I really can't be certain so don't take my word as gospel . In my early post I mentioned the hammer - I should have said hammer, or trigger, or both.
 
I do agree that without a part that is known to work, it is hard to figure out if this one isn't. I will look for replacement parts (if just so I can compare and assuming they too, if used, have not been bubbafied) and see if we can solve this mystery.
