The old style bezels and associated parts are no longer available: specifically the chrome bezel (#530-71), the tolerance markers (#530-80), the ring with crystal (#530-78) and the retaining ring (#530-082). It's been more than 10 years since these parts were replaced with a color coded bezel and a snap-on crystal. However, the bezels for the bore gage indicators are different from the regular dial indicators. The colored bezels for the bore gage have 6.2mm high rims. The regular indicator bezels are larger, at 8.2mm. You can also recognize the bore gage bezels because they’ve been turned down and portions of the coloration are removed in the process. These are the new parts (check the list above for pricing): - bezel (blue) .0005" #041950
- bezel (red) .0001" #041952
- snap-on crystal #041329
- tolerance marker L #041451
- tolerance marker R #041452
- O-ring for crystal #042257
** 042000 is the conical screw which is used to attach the indicator to the measuring head. The new screws are 6 mm long but some older bore gages used 5 mm screws. It's easy to strip the thread by overtightening this screw since the indicator body is brass, so use caution. It could be a costly mistake. You will notice, upon closer examination, that this parts list also includes parts for the metric dial bore gages. Please e-mail us if you have any questions. |
