I do not know. It was removed for an upgrade 5+ years ago.

The gymbal and rotor bearings might need replacing (i.e overhaul) but there's absolutely nothing to adjust or "calibrate". FWIW, a DG can easily be tested for proper operation, just spin it up with the appropriate pressure drop and see how fast it precesses.
