Scoop of work:

• Inspection Propulsion gearbox, Jahnel Kestermann, PGVC-630-435

Bearing pos. 1 of the input shaft, shows a gray dull appearance. No further damages were observed. However no information about the running hours of the gearbox were available.

The main engine running hours are exceeding the recommended gearbox running hours.

If the gearbox hasn’t been overhauled in the past, GBS recommend to replace the bearings during an overhaul. This to avoid an un planned, destruction repair. Please be aware no indications of significant wear is observed, however the condition of the expended bearing lifespan can change rapidly.
