omega 565 shim prob

[gary17]

Hey

Been working on this omega 565 it kept slipping when it was being wound.

I have found something i think may be causing it to slip bit, but i am unsure. Please see pics.

Is this shim supposed to be under the crown wheel as it seems to hold the crown wheel to high, so makes it slip when being wound with the crown gear.

I can not find any exploded pics of the 565 only part charts.

Also the other donor watch (omega 565) also has the same shim fitted.

Any one know anything that might help me.

cheers

Hi Gary  I have attched the tech sheets  Part Numbers 470-1101,   470-1102  550-1103 relate to the parts you are having problems with1101 is the crown wheel    1102  crown wheel core    1103 is the crown wheel seat.   first on is the core  then crown wheel then seal with screw    550- 1100 is the ratchet wheel

picture 4 looks correct but make sure the crown wheel is the correct way up.       cheers

That is correct. Make sure the wheel fits onto the square of the arbor. Check that there is no wear in the hole that the arbor goes through. Also check for wear on the teeth of both wheels .  Are you using the correct screw here? See photo
