Abstract: A retention assembly for a gas turbine engine is provided. The retention assembly may include a bolt, a spacer, a housing, a fitting component, and a conduit assembly. The housing may define at least one receiving aperture sized to receive a second portion of the shaft. The fitting component may define a first through-hole and a second through-hole sized for a first portion of the shaft and the second portion of the shaft to extend therethrough. The conduit assembly may include a conduit for securing to the fitting component such that the first through-hole is open to the conduit. The bolt, the spacer, the fitting component, and the housing may be arranged with one another to define a captive clearance fit such that a first clearance space is defined between a first surface of the second through-hole and the first portion of the bolt.

Abstract: The present disclosure relates generally to a manifold including a plurality of manifold channels disposed therethrough, each manifold channel including a manifold channel opening, and a seal plate, including a plurality of seal plate apertures disposed thereon, operably coupled to the manifold, wherein the seal plate includes at least one seal plate channel extending between at least two of the plurality of seal plate apertures.

Abstract: A clamp assembly includes a grommet with a non-circular aperture with a multiple of crush apertures defined at least partially around the non-circular aperture. A method of supporting a wiring harness within a clamp assembly for a gas turbine engine includes installing a wiring harness through a non-circular aperture with a multiple of crush apertures defined in an arc at least partially around a major axis of the non-circular aperture; and compressing the grommet to compress the multiple of crush apertures to retain the wiring harness within the non-circular aperture.

Abstract: A fuel/oil manifold includes first and second manifold flanges and a manifold tube. The first and second manifold flanges are located in non-parallel planes with respect to one another. The manifold tube is connected at a first end to the first manifold flange and at a second end to the second manifold flange and includes at least one turn between the first and the second end that includes a non-zero tube bend radius defined as the ratio of a turn radius to a diameter of the manifold tube.
