It might be my eyes, but where I have shown your operating arm with red arrow below, it looks like it is not going up to the stop.

If you look at my machine below, the arm comes to rest on the green stop. Does yours, or is there a gap? If so, what happens if you try and lift the operating arm up highlighted in yellow? Does it move?

Yes, your mechanism is from a later machine, probably either a Nevada or Sheerline type. It has a nylon bush on the operating arm lever and nylon star wheels on the reels. I guess swapped in the past.

I just posted a picture from the front of the machine as requested.
I also add a picture with what's going on with the machine right now.

I added a spring between E and E, so the little lever comes up now and the coin can fall into the slot.
Actually, the coin doesn't fall into the slot; it falls on rod D-D (that rod is sticking through the coin slot hole 1cm when the machine is at rest).
When I move lever B a little bit backwards, the coin falls through into the slot.
When I move lever B a little bit more backwards, I bypass the coin mechanism, so A and A do not bind anymore and I can cock the machine and it cycles as it should.
When I move lever C a little bit up, as soon as the coin fell into the slot A and A do not bind anymore and I can cock the machine.
So, why do A and A still bind when I pull the handle?

You never answer either of my questions. The issue you have is that the coin detector lever you describe should not be poking through the hole and block the coin and is pulled back when the operating lever returns to the stop I asked about

[john279]

I'm sorry treefrog, our answers crossed.
On one of my pictures that I took today, I can see that the arm is not all the way up.
I'll check tomorrow morning why the arm is not going all the way up.

This is likely to be the issue, as when it returns all the way up the coin check lever will pull back.

I've worked on quite a few mechs that jammed because of a loose coin falling into the works, I pretty much look for that first thing before getting too into it.

I dont believe this is the problem,but,the machine looks from the photos to be a little too clean,there seems ,from the photos at least, to be be no oil anywhere,of course you dont want any grease,and no heavy oil but a little light oil is needed on the moving parts that dont come into contact with coins. perhaps we just cant see the oil in the photos

[treefrog]

Certainly coins could be causing a problem if they are on edge on the top of the coin tube which is full, as if the coin overflow lever cannot move forward because a stack of coins are on end at the top of the tube the lever will stop the rest of it returning to its finished state. Have a look at the lever below. Is it free, as it will move forward as the main operating lever lifts up?

[john279]

Guys,
I'll check those things tomorrow... I think the lever pointed by the red arrow is free. Also like to know what the function of B is (it's spring operated, no clue what it's for).

[treefrog]

This is part of the coin detector part of the mechanism. As the operating lever is operated, B moves towards the coin, if no coin is detected or a washer is used it will pass through without operating the coin lever that allows play.
