RE: CD transport gear problem

Man, I hate to toss something for the loss of a 0.50$ part.....
But I've got to agree. That plastic? Will probably shatter like glass.

Might be time to start over?

But that being said? Remove drive band and store it. Look UNDER the pully which needs to be removed first and see if you have room to install a puller. You'll have to MAKE such a puller which pulls UP on the gear and presses DOWN on the center shaft as you apply force.....Not rocket science.
I built suck a device many years ago using a desk chair which had a long lead-screw down the center. Worked fine....and I held it together with tie wraps.....

The reason I say that? I see a SAME nut inside the other / broken gear. Use ONLY tools that fit.
The plastic needs perfect fit wrenches....I would NOT use pliers......

Now that I take a SECOND LOOK with magnifier? That shaft is threaded for a couple MM. Holding the gear, UNSCREW the nut on top? But only if it looks like a seperate piece. I can't tell from this image.

Power of Google. Actually found this gear on the net - eduardoo 16:32:13 05/05/23 (1)
Very interesting. Someone actually sells such a thing.
I also found the service manual of a CD player with the same transport.
Looking at the picture, the gear that needs replacing is item 11, and the pulley covering it is item 12 next to it in the pic. Seeing how it goes in (looks like a force fit), does anyone have an idea as to the best way of pulling them out for repair? The thing is that, as seen in my original pic, the metal stub seems to "click" over the hole? Wonder how I should approach this
Thanks.

  I look in detail at #36, the axle to which #12 is attached.
  
  Is that at the TOP intended to be threads?
  
  I don't see any 'nuts' or circlips in the assembly......which may indicate 'press fit'......
  
  It should be possible to fabricate a puller which presses Down on the shaft while pulling up on the gear from most of the underside.
  
  Your local repair shop might be able to assist or give proper advice.
  
  I'd really like to take a look at this, up close and personal!
