Figure 20: Tube Puller Insertion
7. 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.
8. Insert both ends of the tubes into the headers. Insert the lower tube-end into the bottom header first.
Then insert the top tube-end into the top header. Insert all replacement tubes before driving them.
9. Drive the upper and lower tube-ends. DO NOT drive the tube-ends down to the flange. With the driver
tool positioned on the flange, strike the end of the driver with hammer. After a few hits, the feel of the
strike will become solid. The tone will also change from a “Ting” sound to more of a “Tong” sound. This
indicates the tube has seated.
