Angelus 240

[omgiv]

Hi Guys,

 

It has been a while since I have been able to post.  I currently have an Angelus 240 movement on my bench.  I have managed to fix a few of the  issues with it but it still suffers from a keyless works issue.  I believe that the pilot hole where the stem enters the mainplate has become worn, as is the hole for the hub of the stem.  The pilot hole itself doesn't look enlarged.  Just worn from the end of the square turning against the plate.  The hole for the hub has worn so much that the set lever doesn't hold the stem when it is pulled to set the time.  I was wondering what the best route would be to fix the movement.  I have attached a couple of pictures and will try to upload a video showing the play in the mainplate.  Thanks in advance for any advice and help!!!

I would check the stem the pictures I have seen for a cal.240 stem dont look like the one you have it may be why the setting lever does not engage with the stem.

Here is a photo of the stem. wis1971 could be right. First make sure you have the correct stem.

Most often the pilot hole bushing was damaged deliberately to use a wrong stem.

Now and then on my workbench:

Thanks guys for the help.  I am not overly familiar with this movement and finding genuine parts is rather difficult.  I did a comparison shot of the stem I have to the one oldhippy posted and it does indeed look different.  I will try to see if I can find a reliable genuine stem before doing anything drastic.  Thanks for the advice!

Thought I would just give you guys and update and thank you for the help.  I was able to find a new stem and the new stem does indeed work.  The only problem was the threads were larger than the crown I had.  My gauge stops at 1.20mm so I am guessing the stem was 1.40mm.  The crown I have accepted 1.20mm stems.  I cut down the stem on my lathe and rethreaded it.  Thank you again for all of the help!!!!
