Mitutoyo Spare Parts
Dial Calipers series 504 and 505

 

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, particularly those which might be considered "user replaceable" are on the most frequently requested list. See if what you're looking for is here. Mind you, specialty tools may be required to perform any repairs.

If you email us a request for specific parts, be sure to include the model number of the Mitutoyo gage. For some reason, they call this the Code Number. Most Mitutoyo tools have hyphenated code numbers such as 505-123. Include the manufacturer's part number if you have it, or be as descriptive as possible. For example: "the small, black, plastic, rectangular piece with two little plugs sticking out one side... etc."

For other parts: see page 72

  • Digimatic digital calipers ... page 189
  • Digimatic indicators, dial indicators and test indicators ... page 162

 

Be aware of model numbers!

As Mitutoyo gages, calipers and micrometers evolve, the manufacturer adds new suffixes such as -20, -30 or -50 and letters such as "F" and "S". 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.

There are some early models (roughly pre-1980) which may have the same model or code number. However, they had unique parts which are no longer available. We can not be held responsible if you attempt to buy parts for these antiques, and they don't fit.

 

Are you looking to install your own crystal?

Be advised: to install a new crystal in your dial calipers you will need a crystal press. These Mitutoyo caliper crystals are slightly oversized. The crystal press will cause them to become dome shaped and this is what keeps the crystals in place, in a groove inside the bezel. For details on crystal insertion and tools required, see page 15. An alternative solution is to buy the bezel and crystal already assembled (see parts lists below).

 

Some common terminology: (parts for different models may actually look a bit different than those shown in this generic drawing)

ThumbRoller

movementparts


Use this drawing to help identify movement parts. This is a generic drawing and parts may have a slightly different appearance. Buying the complete movement assembly makes for a much easier repair but individual components can also be ordered.

No.8 ... movement assembly (consists of the following)

  • 8-1 ... base plate
  • 8-2 ... top plate
  • 8-3 ... plate screw
  • 8-4 ... pinion assembly (all metal)
  • 8-5 ... pinion backlash assembly (plastic)
  • 8-6 ... center pinion

The slider stop is the plastic end piece (shown right). The color of the plastic may be black or grey. It will have two pegs which press-fit into the openings on the beam. Check the part numbers carefully since there are several variations. In some instances, these are made of metal and involve two screws for mounting.

Please inquire about dial caliper parts not shown on this list.

* note that there are some very old models (pre-1980) which used different parts even though Mitutoyo gave them the same model or code number. Those parts are long obsolete. Make sure you have the more current models.

Notes:

The bezel clamp (141863 and 130366) for model 505-626-50 and 505-627-50 is discontinued but you can use clamp 05BAA112 as a substitute. It works perfectly. The original clamp for the old model engaged the coined edge of the bezel. The newer one engages the smooth diameter on the underside of the bezel, and does so on the older bezel as well. It is actually an improvement. (With thanks to Mr. B. Allenbaugh for this discovery and other customers for verification.)

 

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.
