Abstract
Liquid shim injection devices and methods for injecting liquid shim material into a gap between adjacent components of an assembly. The liquid shim injection devices comprise a body, which comprises an injection shaft, a liquid shim conduit defined within the body and configured to channel liquid shim material within the injection shaft, and a fluid-permeable region formed along the injection shaft, an actuated fluid seal operably coupled to the injection shaft and configured to be selectively conformed among a plurality of conformations, and a fluid seal actuator assembly configured to transition the actuated fluid seal among the plurality of conformations. Methods comprise inserting the injection shaft into a bore that extends through the adjacent components of the assembly, forming a fluid seal between the liquid shim injection device and an interior component of the assembly, and flowing the liquid shim material from the liquid shim injection device into the gap.
