Beschreibung
Zusammenfassung:	The engine has an auxiliary gearbox (12) connected mechanically to a shaft (30) of the engine for driving auxiliary machines. An air starter (10) having an oil enclosure is mounted on the gearbox, where the oil enclosure and the gearbox are communicated with each other such that lubricating oil in the starter is distributed from the gearbox. The oil enclosure is pressurized by an air source e.g. bearing's pressurization enclosure, that is independent from the gearbox. An air return conduit (43) is connected on a wall (124) of the gearbox.
