Who is responsible for retiming locked train gears?

The responsibility for retiming locked train gears falls to OEM (Original Equipment Manufacturer) personnel. These individuals possess specialized knowledge and training directly related to the equipment as designed by the manufacturer. They are familiar with the specific tolerances, characteristics, and timing mechanisms of the gears as established in the original design specifications. This expertise enables them to conduct the precision work required to ensure that the gears operate correctly and efficiently.

In contrast, other personnel may not have the in-depth knowledge of the original design and timing specifications needed for this task. While engineering personnel may understand general principles, they may not have the specific insights into the OEM's guidelines. Maintenance personnel are primarily focused on routine upkeep and repair, and inspection personnel's role is typically to assess the condition and functionality rather than perform retiming adjustments. As such, the specialized training and knowledge of OEM personnel make them the correct choice for this responsibility.
