How to remove Canon pinion from center wheel

[Buf]

Hello everybody. 

I am new to all this. I am trying to disassemble a Lorsa 238 GA movement. But I cannot remove the canon pinion from center wheel. 

Is there a special tool? I don't want to ruin anything, so  I stopped as soon as I was not able to take it out with tweezers.

So I ask.

Many thanks in advance

Tools to remove canon pinions are available.  The key element is to remove it straight up not to pull at an angle .

 

I have bid on several on EBay and failed to win the auction, so I use tweezers.  Not ideal, but one must what one must.

Good Luck,

RMD

You can tighten a pin-vice(stem holder) over the canon section of it  and pull straight out.

rduckwor advice to avoid pulling out at angle is solid.

Good luck

Second best tool to remove a canon pinion is a presto hand removing tool, IMHO.

There's a presto tool for removing canon pinions - it doesn't have a centre push like the hand removing tools.

I just bought another from ebay, as I'm modifying one to remove a 6 spoke train wheel.

Less risk of pulling out at an angle with this.

Here is my video on watchmaker small tools. At 6min in I show a cannon pinion removal tool. Works great and you can pick one up at Daveswatchparts.com
