This two-piece pin is made of super-strong grade 12 alloy steel. The pin fits a 3/32" hex, the 12-point socket of the nut fits a 3/16" hex wrench, no hex wrenches or other tools included. These parts have a durable black-oxide finish, the pin-shaft is polished raw steel. The pin has a shoulder that stops the nut at 3/4" which is the same as the outside tube diameter, this prevents the front of the tube from expanding when force is applied to the pump-lever and also prevents over-compressing the front of the tube. This is the strongest and most stable pin design available in the industry.

IMPORTANT, the following two paragraphs are critical for installing a solid pivot-pin :

The hole in the unmodified factory USA tube is 3/16" slip-fit on the left side and 3/16" press-fit on the right side. This solid pin requires a 3/16" slip-fit on both sides. A standard 3/16" drill bit can be used to enlarge the hole to the correct size. The hole on the left side is usually large enough to fit the drill bit to line up straight with the right side to keep them aligned correctly. The sharp edges of the holes inside the tube should be deburred after drilling to avoid damaging the valve and piston seals. This can be done with a small round hobby file or a 2" x 2" piece of 300-400 grit sandpaper rolled tightly into a tube to use as a file. Insert the file through the outside of the hole at an angle and file lightly around the inside edge until it is dull all the way around, do this to both holes, then file or sand the inside surface around the holes reaching in from the front of the tube to make sure everything is smooth. Do not remove a lot of metal, just enough to dull the sharp edge and smooth the internal area around the…
