Thank you Dr Chris and Mitza
The white gears would be easily replaced (ten tooth?) but that grey one will be problematic. I have not had much success gluing gears as the gap seems to remain causing slippage. Since it doesn't work very good now and knowing my own skills...I would try cutting that grey gear off at its base, locking the metal axle in a rotary tool and using an X-Acto blade making a precise cut and super gluing a new gear to it but thats just me. No guarantee that this will work but if it doesn't work...it wasn't going to work anyway. Of course finding an exact gear would be perfect.
Curious why all the axles are pitted. Are you in a northern area where the weather changes a lot from winter to summer and this was stored in a non-temperature controlled area?
As Chrisjo says, I would grease the axles where they all come in contact with their plastic bearings. But before doing that maybe it will work satisfactory with just replacing all the split white gears.
