Which of the following is not true about aligning a conveyor system for maintenance?

The statement regarding alignment being checked before an initial run-in period is not accurate. In practice, alignment should indeed be carried out during the installation phase, and it is essential to ensure that all components are correctly aligned before the system goes into its initial run. This step helps to prevent undue wear and tear on the equipment, reduces the risk of failures, and ensures that the system operates efficiently from the outset.

On the other hand, other statements are true in highlighting key aspects of maintaining and aligning conveyor systems. For instance, ensuring that all components are aligned so that shafts remain parallel and sprockets are in the correct line is crucial for the proper functioning of the system. Additionally, using a laser alignment tool is a well-regarded practice in aligning larger systems, as it provides a high level of precision. Lastly, having the drive and driven sprockets aligned to each respective sprocket on the opposite shaft is fundamental to maintaining the overall efficiency of power transmission in the system.
