SHEAFFER PLUNGER SHAFT GUIDE (D9)

This tool is intended to prevent you from going nuts while working on Sheaffer pneumatics (Plungers, Snorkels, and TouchDowns). This tool makes it unnecessary for you to poke the plunger shaft around trying to find the hole that goes through the rear of the barrel/seal while inserting the threaded tip of the plunger back through the seal. This operation is especially difficult since the plunger shaft length is close to the length of the barrel of the pen and your fingers don't fit into the barrel. This is almost an exact duplicate of the Sheaffer tool found in Sheaffer repair guy's tool kits. I say almost, because I embellished the design by making the business end long enough to go ALL THE WAY THROUGH the barrels so you can align the dimple (or, on newer models, a screw-on point) into the tip of the tool's shaft with the end of the plunger shaft and slide the shaft right through the seal without poking around blindly. The shaft of this tool is the same diameter as the plunger shaft, so the junction of the two shafts slides through the rear seal. And of course, in an application like this, silicone grease should be used.

A second improvement that I've made is that I've put a threaded hole in the end of the tool shaft where Sheaffer's design only had a dimple on the end. You can now screw this tool onto the pen's plunger shaft.

A third improvement is that there is a screw-on pointed tip that you can use to guide the shaft of the tool through the back of the seal and into the pen barrel. This is especially helpful after you've replaced the rear seal (say, with our RZ tool). JUST BE CAREFUL; THIS SCREW ON TIP IS SHARP. DON'T PUT YOUR HAND OR OTHER PARTS OF YOUR BODY IN THE PATH OF THE SHARP TIP!!! A NEW SEAL WILL REQUIRE SOME FORCE TO GET THE TOOL'S SHAFT THROUGH IT.

The screw-on point is the same diameter as the pen's plunger shaft; the putty shown on the tip below is there to keep the point from rolling while it was being photographed.

Our D9 tool, with the pointed, screw on tip removed, also fits through the hole in the tip of a snorkel sac protector to help push the front plug out of the sac protector. A lot of heat helps in this application.
