If the crystal needs replacement, this is a good time to do it. When putting the needle on, be sure that it is the correct side out, and pointing the direction you desire for the unloaded unit. Take care to put the wave spring, washer, and face back before putting the needle on. Reassembly is the reverse of disassembly.Д¬are should be used pressing the needle back onto the shaft to avoid damage tot he needle or bending the shaft. The point of a needle may be used to apply oil to the pivot points. The procedure is the same as lubricating a watch.

The tip of a needle is used, and any visible excess should be wicked off using a lint free swab. VERY little is needed, or grime will re-accumulate. The spindle, pin, and helical barrel should all be cleaned.ДЄfter cleaning, a fine mechanism oil or watch oil should be applied to the working surfaces: where the spindle passes through the body, where the spindle passes through the inner frame, and where the pin contacts the helical groove.

The grime is cleaned using a fine tip, lint free swab (available from many hobby shops for painting models, or from industrial suppliers for cleaning precision parts and optics) using a naptha, kerosene, or other light solvent. The score in the barrel does not affect the operation in this case, as there are no burrs that interfere with the pin. In this example, grime is visible on the spindle, causing rough, sticky operation. There is a washer and a wave spring under the face to support it, and they will lift out. Once the needle is removed, the face can be worked past the retainers and removed, exposing the mechanism. If you need more information, there are a number of videos showing different techniques, but it must be done with care to avoid bending the shaft. The needle is then carefully removed using a watch hand puller or hand removal levers.
