St36 Center wheel
Question- I ordered a Center wheel for a ETA6497 (ST36) using the part number from the ETA 6497 Technical Communication sheet.
The new wheel had much taller Feathers on the wheel pinion than the original wheel and would not allow the wheel to turn with the Train barrel in place. Plus the new Center Wheel pinion feathers did not match the teeth on the mainspring barrel.
I checked the part number I used to order the new center wheel to ensure it matched the one from the technical sheet. It was correct.
Then I spent an hour looking for a technical Communication sheet for the ST36 movement to see if the part number could be different and looking for the correct Center Wheel that would fix the problem . Mostly my searches came up wth escape wheels or replacements movements.
Any advice or help would be greatly appreciated.
