When replacing the packing, the pieces closes to the piston rod will be the ARAMID FIBER (yellow in color) with the remainder being the woven FIBERGLASS.
Many Pile Hammer mechanics have a tendency to tighten the Packing Gland too tight. A little steam or air leaking through the Packing is not objectionable. The oil mixed with the escaping air or steam will lubricate the Packing and Piston rod.
Note: Tip date 1 April 1985. This was the last of the Vulcan Offshore Tips actually “issued” but one additional was prepared and sent selectively. This is an update to Offshore Tip #3.
