What kind of failure does Tech B associate with part Y as indicated in the figure?

Brinelling failure is characterized by permanent indentations or “brinell” marks in a hard surface, typically caused by excessive loads or repeated impact stress. This type of failure occurs in bearings and is essential to diagnose because it can significantly affect component performance. When the parts are subjected to higher than rated loads, even if briefly, they can suffer from this type of failure, leading to abnormal wear and reduced lifespan.

In the context of the figure referenced, if Tech B associates part Y with this condition, it indicates that the appearance or symptoms of the failure align with brinelling characteristics. Indicators may include visible indentations on bearing surfaces or unusual wear patterns that result from contact stress exceeding the materials' capacity to withstand it.

Understanding this type of failure is crucial for diagnosing issues in manual transmission systems and ensuring proper maintenance and replacement of affected components. This awareness helps in implementing preventive measures, such as using appropriate lubrication and maintaining correct load specifications to prevent recurrence.
