132k5 Help needed to adjust clearance between needle and hook

[Constabulary]

There is so much cast iron you will not overheat it with a heat gun, not even even with a gas blow torch.... you don´t want it "red glowing" just hot enough that the bushing can break free when you tap it.

Is there probably a 2nd screw holding the bushing?

May be a second screw holding the bushing C but should not be.  In my opinion, the bushing should be flush with the right side of the cast piece it is in.  Looks like it can go about 1/8" from left to right!

Sorry for late answer, I have been away for a few days. So I compared both machines and the bushing is moving on my 132k10, in both direction, when gently taping on it, once screw #4 is loose.

There isn't any second screw. The second hole is where comes the bobbin case retainer ratchet I had to remove in first place in order to access screw #4.

Both machines are identical twins for this mechanism. So my guess is @Constabulary is right, probably some rust I will have to stress with heat to unlock that bushing. I'll try that and keep you informed.
