      All:

      Does the oil cup of a hole jewel go toward the cap jewel side or toward the pinion side?

      Thanks!

        Towards the cap.

        Regards

          I should clarify, and say the jewel in a capped setting pair has a flat bottom (towards the gear) and curved top towards the cap.

          If you have a flattish jewel with a reservoir it may be a plain plate jewel, not meant for capping.

          There is a good diagram here
          en.wikipedia.org/wiki/Jewel_bearing
          that might help.

          Regards

          Peter
