Abstract: An engine mount assembly for coupling an engine to an airframe. The engine mount assembly includes a torsion bar coupled between the engine and the airframe. The torsion bar includes an external spline. The engine mount assembly also includes a bell crank having a clamp forming an internal spline with the internal spline of the bell crank adapted to mate with the external spline of the torsion bar to secure the bell crank to the torsion bar such that the bell crank rotates with the torsion bar responsive to movements of the engine.
