The balancing washers were bolted on to the bulkhead not the ring gear.
The ring gear has nothing bolded on it. The ring gear appears to be
symmetric with bold holes. We will be checking the see if the ring
gear has a preferred bolt hole orientation when the prop gets back from
the prop shop.

The ring gear support is "symmetric" with regard to the bolt holes
(technically, they are nut holes...). But, one hole should have a
slightly larger ID to match a corresponding nut pressed in the crank
flange with a slightly larger OD. The other clue for proper
orientation are the timing marks on the ring gear support.

I would hope that the person/s that are maintaining your aircraft are
aware of this.
