View of a gimbal bearing lock.

Picture 5 of 6.

Four of these locks, arranged around the periphery of the gimbal bearing, immoblized the gimbal bearing during shipment, handling, and storage of the engine.

This gimbal bearing lock is located just counter-clockwise of the 9:00 position on the gimbal bearing.
