mainspring arber

[gdjones321]

I have a chffoo china 9805 movement with a bad mainspring arbor,[it won’t catch the mainspring hole] it is worn from slipping.
Would anyone know where I could go to locate one, checked all the places I know?
Any help would be greatly appreciated.

I dont know where you could get a replacement but if you are capable of drilling a hole and tapping it, it wouldnt be a difficult repair?

Those Chefoo 9805 movements are not hard to work on and you can replace that hook. I have worked on a couple of these and you won’t find wheels for these unless you happen to find a whole movement on like ebay. It could be you need to check the inner coil and make sure it is coiled fairly tightly around the arbor. I can’t remember if those hooks punch out or have to drilled as I haven’t worked on one in a while.
