EB 8800 - lubrification of pallet fork pivots

Question

Hi all

 

Just finished service of a EB8800. This is the most basic version of it, with only one jewel in the hairspring pivots.

 

I would usually not lubrificate the pallet fork pivots (and did not on this one) given there is no friction, but since this one is metal on metal, should apply a bit of 9010 to the pivot ends of the pallet fork?

 

Many thanksb0c980a9f2e8a4cc43eeae50f3666859.jpg

Yes you should. Metal against metal is not good and will create wear. Only the tiniest amount is needed other wise it will create drag. So small the amount you can hardly notice it. A good tip also is oil just a few teeth of the escape wheel and not the pallet pins, the rotation of the wheel and action of the pallets will distribute the oil.
