A disposable oil filter containment sheath is provided for use during oil changes for combustion engines. The sheath has a closed bottom, a cylindrical sidewall, and an open top. The resilient sheath is rolled to an initial collapsed position for placement on the bottom of an oil filter mounted on the engine, and it is partially unrolled along the filter. The filter can then be loosened to allow oil to drain into the sheath for capturing a reservoir. After the filter is removed from the engine, the sheath is completely unrolled and tied at the top so as to fully enclose and contain the oil filter and oil. The sheath and its contents are then ready for disposal.

A fan drive gear system for a turbofan engine is disclosed and includes a gear assembly and a front center body. The front center body is an annular case that supports the gear assembly. The front center body includes a passage portion that defines a portion of a core flow path, a forward flange configured for attachment to a first case structure forward of the front center body, and a gutter portion disposed on a radially inner side of the front center body for collecting lubricant exhausted from the geared assembly.

An oil scavenge system of a rotatable machine having an axis of rotation is disclosed. The oil scavenge system comprises a sump housing, a scavenge conduit, a bearing, and a squeeze film damper. The sump housing is arranged about the axis and at least partly defining a sump. The sump housing has a radially inner surface for directing the flow of oil and defining a collection orifice. The scavenge conduit is in fluid communication with the collection orifice and a downstream location remote from the sump. The bearing is disposed within the sump. The squeeze film damper is positioned proximate the bearing. The squeeze film damper comprises an annular channel and a supply line. The supply line supplies oil to the annular channel. The squeeze film damper further comprises a discharge line. The discharge line is axially aligned with and discharges toward an inner wall of the scavenge conduit.
