I'm somewhat puzzled how this thing comes totally apart and how the thimble turns the main gear. I purchased this on ebay. When I received it, it had hesitation when turning but seemed accurate. I tried to take it apart to see if it was dirty or another issue. However, once I backed out the thimble and threaded it back in, it stopped spinning the digits. I then took it apart more and tried to adjust the digit gear mechanism thinking it had become detached from the main gear. It somewhat works, but does stop rotating the main gear which causes the numbers to stop advancing. I can literally push a screwdriver very lightly on the main gear while turning the thimble, and that little bit of force causes it to stop spinning. Basically the tension of the digit gear mechanism is enough to cause the main gear to stop spinning while the thimble moves smoothly. Not sure what causes the needed tension between the main gear and the thimble shaft.
I tried to register on Starrett's site to see the 3D exploded view, but all their 3D links come back with some generic "You have a pending request in queue. It should be resolved soon."
Anyone have a clue how to tear this down further or what might be the issue?
