What common procedures are applicable to all alignment techniques?

The correct answer emphasizes the critical practices in machinery alignment to ensure precision and reliability. Stabilizing end-float and torqueing all bolts evenly are foundational procedures in alignment techniques. Stabilizing end-float helps to eliminate any unwanted movement of the shafts during operation, which can lead to misalignment and potentially cause damage or increased wear on the equipment. Properly torquing all bolts evenly is essential because it ensures that all parts of the machinery are secured evenly, which helps maintain consistent alignment and prevents future misalignment caused by uneven stresses or shifts due to loose components.

In contrast, using a single dial indicator for measurement does not provide sufficient data for accurate alignment, as it limits the scope of measurement and may not capture all potential misalignment issues. Rotating shafts independently while aligning can create discrepancies in measurement because the alignment condition may change with each independent rotation, leading to less accurate assessments. Measuring at only one point on the shaft ignores the potential for angular misalignment and variations along the length of the shaft, which can result in incomplete alignment checks and potential functionality problems.

Thus, the choice about stabilizing end-float and evenly torquing bolts is fundamental across all alignment techniques for maintaining the integrity and performance of machinery.
