550 Rotor Pinion question

My 751 movement runs but stops randomly and I believe it's because of the worn rotor pinion.
I came across these videos which I assume it's @Archer


Is there a way to replace this safely without a Horia tool? Not sure how tight these are connected to the oscillating weight, but was hoping I could do this on my own. Thanks in advance!

A staking tool can be used to do this job. If you don’t have a staking tool, that could be a problem.

Thanks for the reply. Could you send me some links that I should look into?

Do you mean links that show how to replace the rotor bearing gear without appropriate tools? If that is your question, then no I can’t recommend any links.

Oh I meant links to the tool itself as I'm not quite sure which tools you're referring to. Thanks.

Go to Google, and search for “watchmaker’s staking tool”.

How do you plan to ream out the new pinion to fit the axle?

Hmm, I was hoping to gently press it down with force but as I'm typing this sounds like a bad idea. I'll take it to my watchmaker.

This is not a DIY job...

Not that Al needs my support but my watchmaker always tells me that there is risk even when he inserts a bushing. If the watchmaker is concerned... then step away from the watch!
