Starrett dial caliper series 120 and 120A
Spare parts list for 6", 9" and 12" Starrett dial calipers


Starrett 120A-6 Dial Caliper, 0-6" Range

We are 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.

For some instructions and tips on repairs of these dial calipers, please take a look at page 44.

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. The letter "A" will tell you that you have a new style model. 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.

PT27366

PT27366 (Item #27 in the drawing) is the black plastic end stop. It has two plastic pegs which get pushed into the openings on the beam. If you need to slide the beams apart, you will have to remove this plastic stop. If the old stop broke off, you will first have to remove the plastic stumps which may still be in the beam. The 12" models use a different, larger end stop. See below.

Notes: the bezel is now plastic and sooner or later you may have to replace it. This is easy to do. It comes with a crystal already installed. Unfortunately, metal bezels are no longer an option with Starrett calipers.
