Final answer:
The correct option is a) Use a different size cotter pin The correct practice when a castle nut does not align with the cotter pin hole is to align the cotter pin hole with the next available castellation.
Explanation:
When installing a castle nut, and the nut castellation does not align with the cotter pin hole in the bolt within the torque range, the acceptable practice is to align the cotter pin hole with the next available castellation. This is preferable to using a different size cotter pin, adjusting the torque range, or using a different bolt, as it ensures the nut is secured within the specified torque values while allowing for the use of the safety cotter pin. It is crucial for maintaining the integrity of bolted connections in mechanical applications.
