Abstract
A bearing lubrication tube for an APU is mounted on a bearing to permit expansion and contraction of the tube along its length while preventing rotational movement of the tube. The bearing lubrication tube is held by a bracket attached to a flange outside the engine. The bracket includes a double hex ring with the outer hex ring engaging the bracket and an inner hex ring engaging the tube to prevent rotation of the tube. A cover on the bracket maintains the double hex ring in position.
