Which is NOT a task involved in preparing for precision alignment?

Checking fluid levels, while important in overall equipment maintenance, is not a task specifically involved in the precision alignment process. Precision alignment focuses on ensuring that rotating machinery components are aligned correctly to prevent excessive wear and tear, reduce vibration, and improve efficiency.

Tasks directly involved in this process include cleaning the work area to provide a safe and unobstructed environment for alignment work, preparing shims which are necessary for adjusting the alignment of machinery components, and removing any components like taper pins, jacking screws, or coupling bolts that may obstruct proper alignment. These steps facilitate a more accurate alignment procedure, ensuring that every factor affecting alignment is addressed.

In contrast, checking fluid levels does not directly contribute to the alignment accuracy; it pertains more to the overall operational readiness and maintenance of the equipment rather than the specific alignment task at hand.
