ABSTRACT:
The tool is useful for the replacement of the lateral control torque tube bearings on high performance aircraft. The bearings are pulled into position into the bulkhead in a straight line thereby preventing them from becoming jammed because of the angle of the bulkhead surface into which the bearings are to be installed. The tool self-aligns the bearings without putting pressure on the bearing race thereby preventing the possibility of damage to the bearing and since the use of a shoulder driver and hammer are no longer required, damage to the bearing and/or aircraft is virtually eliminated.
