America is a land of do-it-yourselfers. If you want to give caliper repair a try yourself, here are some of the spare parts you may need. Important: some parts are different for the old (120) and the new (120A) dial calipers. Pay particular attention to the presence or absence of the alphabetic character after the model number. You'll find the model number stamped on the front end of the calipers. Understandably, some parts are different for the 6-inch, 9-inch and the 12-inch models as well. 
A BIG word of caution! These parts will only work with the American made model 120 and 120A calipers. They will not fit the Starrett 1202 calipers made in China. But, you already knew that. |
