Before that, though, the gear specialists had to separate the two planetary stages in the installed state. The entire job, including removal and reinstallation, was completed during the plant’s four-week wintertime production pause.

In many cases, a general overhaul would be desirable, but the prolonged downtime, or perhaps the lack of a good extraction option, makes it appear unfeasible. Consequently, repairs are often limited to in-situ mending and patching in order to fix acute damage and keep production going.
