Standard Gage dial bore .0001" indicator
Spare Parts List


Model D1-20241-B-1 for gage size 2 through 6

These indicators and dial bore gages are discontinued. Most parts are no longer available.

(For Standard dial indicator gage size 0 through 1 see page 172.)

 

The dial indicator portion of these bore gages is made by Kafer (Germany) although the bore gage may be labeled "made in Switzerland." The parts for the indicator fit directly into the bore gage housing. For that reason, the indicator alone can not be purchased separately. But, the entire indicator units (housing, indicator and handle) are available (see page 71). See below for older indicators not made in Switzerland.

Standard dial indicator model D1-20241-B-1 (.0001") does not have a revolution hand. The main hand goes around 3-1/2 times. It is preset at 10 o'clock.

The manufacturer claims the accuracy for this indicator is ± one graduation per total travel, and repeatability is 1/5 graduation.

The front of the indicator consists of:

  • dial #B-24122
  • hand #5.2006
  • spacer #5.2345
  • o-ring #5.2706
  • plastic crystal #5.2101
  • retaining ring #3.1003
  • bezel #020128/7

The movement consists of the following components:

These parts do not apply to the old Poughkeepsie model no. D1-20241-B (made in USA) nor do they apply to the newer Dorsey brand bore gage indicators.

Repair hints: if the hand on the indicator shifts as much as 1/4 turn when you press on the sides of the case, then 9 out of 10 times it is due to loose screws on the brass plate which you will find underneath the movement. This requires careful disassembly and should only be attempted by skilled hands. We assume that vibration loosens these screws. In some cases, they are almost completely disengaged.

 

Are you looking to replace the entire indicator?

 

The unit consits of the indicator, its housing and the handle. This may be a better way to deal with broken equipment than trying to find parts. This new unit, made by Dorsey Metrology, can also replace the old "made in Poughkeepsie" indicator. Take a look at page 71 for information.

Maybe it is time to move on to something else? Consider this Mitutoyo dial bore gage set:


Mitutoyo 511-932 Dial Bore Gauge, 0.7"-6" Range, 0.0001" Graduation, +/-0.0008" Accuracy



 

Poughkeepsie model D1-20241-B and D1-20211-B

 

The following parts are for the dial indicators for Bore Gage size 2 through 6 only. These older models were made in Poughkeepsie, New York. It will say so on the dial face. They are completely different from the current models and parts are not interchangeable between the two. Only the following Poughkeepsie parts are still available.

The following parts can be ordered on page 156.

 

Order no.

Item

X1-33163 [$]

crystal #660 (requires press for insertion)

X2-82156 [$]

bezel clamp screw (screw only)

Q: Is it also possible that crystals will shrink over time, thereby falling out? We cannot get this one to stay in as it is definitely small.

A: Yes, the crystal can shrink with time especially when certain chemical fumes or unusual temperatures are involved. You will want crystal #660 but it has to be installed with a crystal press. If you do not have a press, please send us the bore gage indicator or the bezel alone and we will install it.
