Loosen tube-ends. Insert tube puller between the tube-end and header. Apply pressure to the
puller and strike the side of the tube two or three times with a hammer to help loosen the tube-

with several blows with a hammer on the end of the handle. Alternate with downward blows to

5.
Prepare the headers and replacement tubes. Before placing a new tube into the header, clean
the holes by wiping gently with emery cloth to be sure that there are no burrs. Clean the
replacement tube-ends of any rust or debris. With a small brush, apply a thin coating of gray
pipe dope around the inside of the hole. Pipe dope may also be applied to the tube-end. Cutting
oil may be mixed with the pipe dope for easier application.
