I’m planning on taking a Vostok 2415 of mine apart for servicing. Having serviced a few 2409s I’m familiar with most of the process but I need info on how to tackle the parts of the automatic winding system. I’m always afraid of damaging things and of springs and the like flying into space. I browsed Ratfaced Git’s videos but he only takes a 2415 (and 2416B) somewhat apart. Any tips on videos or posts on how to proceed?
Thanks comrades and have a nice weekend!

Repair / Disassembly / Assembly: 22xx and 24xx
p. 10 post #97
In preparation for eventually servicing a 2416B movement, I’m servicing a 2414A (my first) to make myself familiar with the date complication. Before this, I’ve only been working on 2409 movements which I’m now beginning to feel pretty well familiar with and this made me notice an unexpected difference.
The watch I’m working on is a "scrap" Komandirskie that I picked up on eBay for a few dollars. As can be seen in the picture it has the 3AKA3 label on the dial.
What I wonder is if the difference I found is related to the fact that it is a 2414A movement or the fact that it is a 3AKA3 "version", or that the explanation is something entirely different?
So, the difference I found is that the cannon pinion, the seconds hand pinion, and the cylinder of the hour wheel is taller than that of the 2409 movement. For example here is a picture of the cannon pinion of the 2414A (right) and the cannon pinion of a 2409 (left) side by side.
My guess is that these parts need to be taller to make room for the date wheel, i.e. that it is a characteristic of the 2414A movement, and consequently, these parts (cannon pinion, seconds hand pinion, and hour wheel) are not interchangeable with the 2409 movement, no?
My next question concerns the hands. As can be seen in these pictures, the hands are rusty, and as can be seen on the dial, the underside of the hour hand has been scraping into the dial. I’d like to keep these hands but I need to get rid of the rust, at least on the underside of the hour hand. I’m afraid that if I try to scrape off the rust I’ll scrape off the corroded lume too. Any recommendation!? Out of curiosity, should I want to replace the hands, would standard 24xx hands fit?
As it's been a couple of days since I posted the above and no one has replied, I just want to add that I'm planning to dismantle one or two more 2414s in the coming months or so. I then hope to be able to conclude whether the taller cannon pinion, seconds hand pinion, and hour wheel is a characteristic of the 2414 or not. I'll report back then!

I'm happy to report that comrade schnurrp has confirmed that the cannon pinion, seconds hand pinion, and hour wheel of the Vostok 2414A and the Vostok 2409 are not interchangeable. Valuable information, so thank you very much!
(I'm sure this information is available elsewhere on the Internet, perhaps even here on WUS, but hopefully, this post will be useful to some future wannabe Russian watchmaker just like me )

Some Vostok 24xx Cannon pinion approx. heights:
2409: 2.09 millimetres.
2414A: 2.58 millimetres.
2415: 2.62 millimetres.
2415SE: 2.57 millimetres (Meranom's SE Amphibians).
I had a set of aftermarket hands recently where I was unable to get the seconds hand to mount on a 2409. There didnít seem to be enough depth on the tube.
I assumed that the problem was with the manufacturer but the above indicates it could potentially have been 2409 vs 2415/6 issue.
Has anyone else experienced this?
