Abstract: A method of installing a seal in a bore of a component includes, among other things, slidably orienting the component in a support fixture. The method includes securing a base plate to the component. The method includes arranging the seal onto a pusher. The method also includes inserting the pusher into a hole in the base plate. The method further includes installing a hub onto the base plate and over the pusher. The method further includes rotating a rod relative to the hub to advance the pusher and seat the seal in the bore.

Abstract: A seal testing tool for use with a bearing housing of a gas turbine engine including: a first end surface; a second end surface opposite the first end surface; and a boss extending away from the first end surface. The boss extending from a proximal end located at the first end surface to a distal end located opposite the proximal end. The boss includes: a passageway extending from the distal end to the second end surface through the boss; an external surface extending from the proximal end to the distal end; and a seal groove in the external surface located at the proximal end of the boss.

Abstract: Aspects of the disclosure are directed to a first device coupled to a bearing compartment structure, a second device coupled to an engine case structure, and a controller. The controller is configured to: issue a command to one of the first device or the second device to generate a signal, obtain data from the other of the one of the first device or the second device, where the data is based on the signal, process the data to determine that a skew exists between the bearing compartment structure and the engine case structure in an amount that is greater than a threshold, identify at least one torqueing device to activate based on processing the data, and cause the at least one torqueing device to activate to cause the bearing compartment structure and the engine case structure to align within the threshold amount.
