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.
Claims1
A bearing puller alignment tool for installing ball bearings in an aircraft part having one opening in an angularly oriented wall surface, said tool comprising a shaft with threads on each end thereof, a pair of flanges slidable along said shaft, a lip disposed on the inner face of each of said flanges at its outer circumference to cause pressure to be applied only to the outer ring of the ball bearings when the bearings are pulled into position, a thrust washer positioned on each end of said shaft adjacent the outer faces of said flanges to minimize the effect of friction when the bearings are pulled into position, a collar on the inner face of each of said flanges for holding said bearing, the inside diameter of said bearings fitting over the outside diameter of said collars, and a nut on each end of said shaft in engagement with the threads thereon whereby the tightening of said nuts produces a corresponding inward movement of said flanges and bearings causing said bearings to be pulled into position in the aircraft part along a straight line regardless of the angularly oriented wall in the aircraft part.
