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.
