Mitutoyo Indicator Spare Parts
for Mitutoyo dial indicators, test indicators and Mitutoyo Digimatic indicators

 

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. Although some parts are user replaceable, most parts will require special tools as well as experience in repairs.

Be advised that we can not offer refunds for parts you may have ordered in error.

 

Be aware of model numbers!

As Mitutoyo gages, calipers and micrometers evolve, the manufacturer adds new suffixes such as -30 or -50. This little detail must not be overlooked when ordering parts. The model number is always printed somewhere on Mitutoyo gages, if not on the dial. The most recent models of dial indicators will have the letter S attached to the number.

  • -10 models have jeweled bearings. This does not affect any other parts when ordering.
  • -60 models are waterproof. Some parts are likely to be different from the standard models.
  • indicator model numbers ending in SSN are designed for Sunnen bore gages (they have a custom stem diameter). Parts will be the same as the models ending in plain S.
  • Most digimatic indicators have the letter B attached to their model number, such as 543-262B. This means the indicator has a standard, flat back and nothing more.

     

Mitutoyo dial thickness gage

The new style lifting levers have a plastic mount which breaks pretty easily. Obviously no one bothered to field test these new models, or they'd have noticed. The mount isn't available separately, so you'll have to buy the new style lifting lever, which is easily installed. The old style lifting levers were all metal, but they won't fit on the new gages (with some exceptions such as model 7328S). When looking for parts, pay particular attention to the letters F or S which may be part of the model number. Also, refer to the photo at the bottom of this page.

How to place an order:

newarrow8a51aTake note of the part numbers and quantities and proceed to page 187 for prices and ordering.

*Illustrated notes


New style "S" indicators have a
3-piece bezel clamp which attaches to the indicator's dovetails located on either side of the body.

You may want to order all 3 parts of this clamp (dovetail bracket #21AAB161, bezel clamp #21AAB163, and bezel clamp screw #101214) as shown here.

This clamp can not be used with the old style indicators.

CAA149
Mitutoyo bezel and crystal assembly 21ACC149 comes as one unit. A clear plastic crystal is glued atop the black plastic bezel. The o-ring which holds this unit in place on the indicator is not included and must be bought separately. You will have best results if you replace the o-ring whenever you replace the bezel/crystal assembly.

Bezels and crystals are model specific. Be sure to check the listing above to order the correct item for your model.

For further instructions and tools for crystal insertion see page 15.

CZA003
*Hands
(pointers) have a small hole that has to be press-fit over the shaft of the center pinion. For that reason, the holes are always a little undersize.

You may find that reaming the hole with a very fine reamer is called for (see photo). If you try to tap the hand onto the center pinion otherwise, you may end up breaking or bending the shaft. This is a task better left to pros with proper tools.

You can order miniature reamers on page 31.

 

Mitutoyo902794
Lifting lever 902794 includes the screw which fits into the top of the spindle. It does not include the screw which mounts the lever to the indicator body. On most models, this lever can be mounted for left or right handed use.

Lifting levers are model specific. Before ordering, be sure to check the parts list.
