What did I do wrong with these keyless works?

Question

Hello again! from the Mockba bench! For those of you who haven't seen my previous posts, this is a 1950s Mockba watch made in the First Moscow Watch Factory. It's my first build, and I'm really excited that I've made it this far, but the keyless works appear to be an impasse. I would greatly appreciate your help!

I've assembled the keyless works, as seen in the attached pictures, but I cannot push the crown or pull it out at all.

 

Here's some details on what I did to assemble the keyless works:

 

1. Pushed in the crown all the way

2. Put the clutch lever in the groove of the clutch

3. Pushed the clutch outwards as far as it can, which also moved the clutch lever and the set lever

4. Wedged the lever spring against the clutch lever so it stores potential energy

5. Screwed down the cover plate, ensuring that the little peg sticking down from the arm of the cover plate is pressed against one of the notches (which I assume is for this purpose) of the set lever

 

Any idea why the whole thing seems to be firmly affixed, but so much that the crown cannot be pulled out at all? Thank you!

I haven't worked with this  ROEDA Watch movement but I Think you have to lift the detent spring to the other side of the pin on the setting lever.
I assume there also is somekind of spring too underneath the setting bridge which pushes on the yoke forward.

Yes, there is a spring that is pushing on the yoke lever, and I believe it has been placed properly.

 

I'm sorry, I didn't quite understand the part about the pin and the setting lever. Does this mean I have to screw down the cover plate when the crown is pulled out, so that the setting lever is in a different position?

I suggest making a habbit of taking pictures at each stage of strip down, for possible use during assembly, furthermore, posting such pictures in gallary goes to create a valuable data base of the kind.

I don’t see any sign of any oil or grease. It just might be its hard to set because of lack of lube. One other thing, check you have screwed in the correct length screws, if you have put in the wrong screw it could be fouling the setting lever. Have you oiled the cannon pinion? if not you might strip the teeth of the wheels when it comes to setting the hands.

I really wasn't sure what to lubricate, so I lubricated the crown a bit, along with the point where each wheel contacts the pivot. Are there other places I should lubricate?

Also, to be more specific, I'm unable to pull the crown out at all, it's not necessarily winding that is the issue. Could this be affected by a lack of lubrication as well?

Also, I am quite certain that I have put in the correct length screws... I recorded screw length on disassembly. The one that goes through the eyelet on the setting lever is a distinct screw, as I believe it's the screw that you use to release the crown from the movement.

    • Update I discovered the setting lever when crown is pulled all the way out does not engage because (see picture below) the post on my timing lever is gone so the lever was not secured at axis point which limited the range in which the lever could full extend. I ordered a new one should be here in a week. I will keep you updated, what I think happened is someone pushed the setting lever post to allow stem to insert or remove and they pushed it to hard and broke it.
    • There is a Jasco made Naphta sold in hw home improvement stores in the US. It's described as being the thinner for varnish and enamel. It also says that it cleans greasy, waxy, oily surfaces and machine parts. Would this be safe to use on watch parts including balance complete?
    • Hello everyone, My name is John but you can call me Jack. I am new the group here and have been a hobbyist repairer for the past 2 + years. I mainly stick with mechanical watches but from time to time I will tinker with old quartz Seiko watches which I love. A current project that I have been trying to get down is a Seiko 4336 8129. This watch has been fighting me from the start. Well the movement was dead due to a broken pivot on the motor. So I sourced a replacement movement. Next Crystal was cracked so I removed the broken glass but can't figure out how to take the top bezel ring off. I have some pics. This poor watch has had a rough life. I was trying to bring it back!! Thank you for reading my tale of woe!!  
    • I am looking for a camera with a macro function to photograph my work.  I had a 18 or 20 megapixel Sony point and shoot that worked great for super close pics, but lost it in a fire.  Dont remember the model but it was a pocket sized camera I could zoom and focus on pallet stones with excellent definition.   It was less than $200 US.   Now I can’t find a camera that will do the job for less than $500  Any suggestions?
    • Can you repair my Timex Rally also?
