Which issue could result from improper caging of the case halves during assembly?

Improper caging of the case halves during assembly can lead to internal component damage. When the case halves are not properly aligned or secured, they can shift or move during operation. This misalignment can cause excessive wear on gears, bearings, and other internal components, as they may not meet their intended contact points or tolerances. Over time, this can lead to catastrophic failures, such as broken or chipped gears, which necessitate expensive repairs or complete replacements. Ensuring that the case halves are correctly caged maintains the structural integrity of the assembly, preventing misalignment and the subsequent damage that can occur to internal components. This is critical for the longevity and reliability of the machinery.

Other considerations such as fuel consumption or performance enhancement do not directly relate to the immediate physical integrity of the internal components caused by improper caging.
