6)
When the temperature of the bellows (3) and the shaft collar (5) rises to a point that will cause the solder
to melt and flow into the joint, discontinue heating with the torch and apply solder (2) to form an even-
continuous fillet around the bellows and shaft collar.
NOTE
In steps (7) through (12), refer to figure 4-29.
(7)
Position the sleeve bushing (3) onto the shouldered shaft (1) and up against the bellows (5). Preheat the
sleeve bushing and bellows with the torch. Periodically remove the flame of the torch from the area
being heated and apply solder (2) to the joint of the sleeve bushing and the bellows. If the solder does
not melt into the joint, remove solder and reapply heat from the torch.
