Resetting a Satrrett Caliper?

I Have a 120A-6 EDP64514 6" dial caliper that had gotten the 0 shifted to about the three O'Clock position. Somehow a piece of crud got between the wheel and gear and made it skip some teeth. I know that I can simply rotate the dial face and move the zero to the three O'Clock position. But that bugs me. I have a cheaper 6" caliper that came with instructions and a shim for taking care of this problem. I bought the Starrett calipiers new, but for the life of me I can't remember if instructions came with it or if they did where in the world they are now. I spent a frustrating 30 minutes searching around the Starrett website but couldn't find a link to owners manuals/instructions.
Can anyone point me in the right direction on this?
Thanks

Call them Jim and ask for help. They have or had a tech support.
 
Hi Al,
Long time no hear. Yep, I'll give them a call, but I have to wait until Monday morning. Figured I might get some advice over the weekend on the forum.

If you have no luck

with Starrett, contact Long Island Indicator Service. I have had a few items repaired by them. One of the items was the 120A. It was not worth the money to have it repaired.
 
Lesser brands

With lesser brands of calipers, I have been able to correct this condition. What I did was remove the "stop" from the end of the caliper, and then slid the moving portion of the caliper completely off the "rack". Then you can turn the gear to any position you want with a small pick, and slide it back together. When you get the needle back to where you want it, re-install the "stop" on the end of the calipers.

Take a small paper clip and and open it up so it is double lenght and strait. Open the caliber up half way, then slide the paper clip between the rack and into the back of the dial till it stoppes then close the caliber slowly till you fell resistance and a slight bump, then remove the clip and close calibers. If not back to zero it may be half way and if so try again.

Thats the way i've reset mine, it may seem crude but it works. If this doesn't make sence let me know and maybe a phone call will do it. thanks.
 
I had a set of 6" Mittoyo calipers and they came with a flat copper"setting tool" that you slide in from the Jaw side of the caliper under the rack, rotate the dial to -0- and close the caliper. As Mike L. states you can use a small pieece of shim stock or a tiny number drill or a paper clip. All the tool does is raise the pinion so it doesn't turn when the slide is moved.

Hey All,
The paper clip trick worked!! My less expensive calipers also came with a thin copper shim, but it just wasn't long enough for the Starrett. But the paper clip did the same thing, It took a couple of tries but now the 0 is back at 12 O'clock. I'll stick a paper clip into the case with some masking tape for future use.
Thanks for all the help.
