| How is the axial clearance indicator used on a turbine? |
| A) The axial clearance indicator is inserted in the depth gauge well until it rests on the reference boss, and the reading is noted. |
| B) After the axial clearance indicator is screwed into contact with the rotor, shims are placed in the clearance well, and the thickness is measured. |
| C) The arm of the axial clearance indicator is pushed so contact is made with the end of the rotor, and the reading on the scale is noted. |
| D) A bridge gauge is placed across the bearing, and the gap between bridge and rotor is measured by the axial clearance indicator. |
