Mitutoyo Spare Parts
Mitutoyo does not sell parts directly to end users. It will be necessary to place your order through a dealer such as Long Island Indicator Service.
While we stock all the items commonly used for repairs we can't possibly list all of them here. However, a couple of items are on the most frequently requested list. See if what you're looking for is here. For other types of Mitutoyo parts, see page 72.
Detailed parts breakdowns and parts lists are available for most models at the Mitutoyo web site.
Be aware of model and code numbers!
As Mitutoyo gages, calipers and micrometers evolve, the manufacturer adds new suffixes such as -20, or -30. This little detail must not be overlooked when ordering parts. On older gages it is also important to look for the serial number since parts can be different. The model number is always printed somewhere on Mitutoyo gages. On digimatic calipers you will find it on the label on the back of the gage. It is easier to look for the hyphenated code number than the rather confusing model number.
This schematic drawing is representative of the Digimatic calipers allowing you to identify the parts by name. Waterproof models will have some parts not shown here. You will immediately notice that the caliper frame with the jaws, and the beam are not available as spare parts. If these are damaged, you'll have to send them for repair or replace the calipers.
Reading unit assembly 09GZA253 includes the "works" but not the battery nor the battery cover.
Most of the time, the plastic cover, with the buttons and glass, is not sold separately. Although, for some models (you will see the items listed below) the cover can be ordered separately from the reading unit.
In most cases, replacing the reading unit couldn't be easier. There are four screws that hold it in place, from behind. You will probably have to remove the sticker with all the model information that covers the back of the caliper. Use a razor blade and a little solvent to pry the sticker off (watch your fingers!). You may want to re-use it when you're done. A small Philips screw driver undoes the unit. Then you may have to remove the roller hook which is also held in place by another screw. Now the old unit just lifts off. After the new one is screwed in place, you'll want to put the battery and battery cover back on. You will need the old battery cover because new units don't include these. There may be enough sticky gum left on the label that you can just glue it back on. Otherwise, some two-sided tape, or a bit of silicon will do the trick. You will probably be pleased as punch with your own efforts.

Sorry, we can not ship parts to Canada or Mexico or any other country which has its own Mitutoyo distributorship.
