Before adjusting motor position during a shaft alignment, what should you remove?

• A. Dial Indicator
• B. Torque Wrench
• C. Vibration Sensor
• D. Lubricant

Answer: (A)

Dial indicators are used to measure how far the shafts are misaligned, but they should be removed before you move the motor to adjust its position. Moving the motor while the indicator is attached can damage the sensitive probe or give false readings, since the indicator may be struck or bent during shifting. Detach the indicator, make the positional adjustments, then reattach to re-check and fine-tune the alignment within tolerance. The other items—torque wrench, vibration sensor, and lubricant—aren’t part of this immediate adjustment step: a torque wrench tightens hardware, a vibration sensor monitors condition, and lubricant is for lubrication, not for guiding the adjustment.
