An assembly for removing a bushing is provided including a mandrel having a size and shape similar to the bushing and a receiver having a hollow interior cavity. A fastener extends through an opening formed in both the mandrel and the receiver. A socket attachment has a first opening configured to removably couple to a first end of the fastener and a second opening configured to removably couple to a torque delivery tool. A biasing mechanism arranged adjacent a second end of the fastener is configured to generate a biasing force to drive the mandrel against a bushing in response to a coupling of the socket attachment and the fastener.

Method and assembly for extracting press fit bushings

An assembly configured to prevent damage to an object during manufacture thereof is provided including a first housing having a substantially hollow interior. An exposed first planar surface of the first housing includes an inlet port and a plurality of small openings formed about the periphery. The inlet port, the hollow interior, and the plurality of small openings form a fluid flow path through the assembly. A second housing similar in size and shape to the first housing, has an exposed second planar surface. An intermediate layer is arranged between the first housing and the second housing. A cross-section of the intermediate layer is configured to change shape in response to a compression force applied thereto by the first housing and the second housing to form a seal separating an exterior portion of the objection exposed to the plurality of small openings from an interior surface of the object.
