Compac dial bore gage parts list
Model IA00A (.15 to .27") and model IA00 (3,75 to 6,75mm) measuring heads
—this page is for reference only—

These are the same parts used by Interapid, Alina and SPI dial bore gages made in Switzerland. All of these are discontinued and no longer available.

The parts drawing for the two smallest (.16" and .18") heads is shown to the right, above. These do not have centering devices.

Spare parts for these bore gages are no longer available from us, as we conserve stock for our own repairs. You are welcome to send repairs to us, if necessary.

Parts for the dial indicator for this bore gage are listed separately. For Compac dial bore gage repair service see page 30.

* The standard size original horizontal rack (.20-.26") is #044060. The larger diameters and lengths listed are available for repair purposes. They may not always be in stock.

** This contact is used for all .16", .20", 4 mm and 5 mm bore heads. The thickness of the contact is 0.55 mm. Contacts need to be cemented in place which is not an easy process.

 

damagedboregage
One of the quickest ways to lose your valuable measuring head is to try and fix it yourself!

The carbide contacts are glued in place and they can break off when you are rough with them. Use extra care when inserting into a bore; don't try to force it and pull it out carefully when done.

This customer, frustrated with repeated glueing attempts, resorted to a method of peening which permanently damaged the bore gage head. There is now nothing he can do but replace it.

Lesson learned?
