Hello All,

Is there a special tool - or perhaps special instructions - to remove the hour tube bushing on this caliber? Almost fifty years repairing clocks, including Atmos, and there's still much to learn. :)

Thanks.

A long pin punch should do it. Put the wheel on an anvil and tap it out. I use a socket for this. I forget the size, but obviously one that is only slightly bigger than the wheel. This provides support against the plate while putting no pressure on the wheel. You want to use the largest punch that will cleanly fit in the tube. Too small and you risk damaging the bushing.
