Working on these pump guns is a pain in the neck as you always have to drive out, and drive back in, that annoying roll pin.

I have offered a nice Shoulder Bolt solution for some time now, but decided to offer this clevis pin idea, too.

The pins are offered in both a long and short version. I have removed a bit of the material in the "short" version to make a more streamlined look.

That's the only difference. It's only about 1mm on each side. The long version looks more substantial, the short version looks streamlined. Buyer's choice.

Both the pin and rings are included. Replacement rings are available, if needed.

Also available is a 3/16" drill bit. The bit is not needed. You can force the pin through the main tube, but cleaning the hole with the bit does make the job a bit easier.

Also, for full disclosure, I did take a bit of sandpaper to the very tip of the P1322 plastic pump arm in the photos. Makes for a cleaner look.
