Question

Quizplus · Accepted Answer

The alignment should be done at operating temperature to ensure accurate alignment under normal operating conditions. Aligning at room temperature and then operating at a higher temperature can cause misalignment, leading to premature wear and failure of the motor and driven mechanism. Alignment does not need to be repeated after running for one minute or heating with a torch, but it should be checked again after several days of operation to ensure that alignment has not shifted due to settling or other factors.
