Pilot Murex - I had done some minor repair on this pen for the original owner but have since then acquired it for my own collection. For the repair I did , a full disassembly was not necessary. I pulled the cap off yesterday and the section came loose with it. This is what I saw. Is this normally adhered to the inside of the section like an inner cap in a pen cap? I don't seem to be finding pictures of such a part over the feed as of yet. I also need to disassemble the feed and section which I assume will take heat. The notches on the black section piece and the notches(tabs?) on the metal aren't matching. I am thinking perhaps the section was torqued at some point in the past. EDIT - After using some common sense I have the feed and all separated. I'll get the sleeve back into the section and go from there. BUT, what is the partial ring piece technically called? It was on the feed end of the threaded "coupler" the feed was screwed onto. It doesn't seem like part of the ring is missing so I am guessing this is the full piece. I am amazed it didn't come off and disappear into the pen part triangle. The Saint of tiny pen parts must be on my side today.

I recently brought the clock back to life in my Murex Quartz. Fundamental problem was missing battery contacts, which I replaced with improvised parts. The LCD looks a bit suspicious, but it is working for now. LCD artifacts are mostly hidden under the face frame. Currently monitoring to see if it lasts. First step it to remove the clock unit from the cap. - This assumes that the inside of the cap is clean. - There are no retainers to remove - Unscrew the battery cover and remove the battery. - Stand the cap on end on a firm surface, battery end up. - With the eraser on a standard wooden pencil, push down on the floor of the battery compartment. - Once it starts moving, it slides right out of the opposite end. - As you will see the fairly robust plastic carrier takes the physical loads Step-by-step photos are at murex quartz clock unit The picture titles plus the labels I added on some of the pictures should explain it pretty well. If you are not familiar with pbase: just click on any image then use next and previous buttons. To return to the gallery level, click the gallery name at the top of the page. Select image size at bottom center. "Large" will probably work best. Most of the corrosion looks like simple surface verdigris rather than from acid - as from a leaking battery. A battery leak may have contributed to the missing battery contact, but the missing case contact, protected by the carrier is a mystery. Note: to press the unit back into the cap, you will need something narrower than the pencil, in order to fit it inside the open cylindrical end of the plastic carrier.
