Compac test indicator spare parts
Series 240 (horizontal model with single revolutions)

The same parts are used for Mercer and SPI test indicators made in Switzerland.

These are single revolution indicators. The hand is set at 5 o'clock and should make about 1-1/4 revolutions. The crystal needs to be inserted with a crystal press.

All parts are available for the models listed below. The parts drawing is generic and the actual parts may vary in appearance.

If you'd rather have us take a look at your indicator, please see page 30 for details.

*How do you tell new style from old style? The old style had black ball bearing cases. The new ones have shiny chrome cases. These can be seen near the front of the body. There's no need to dismantle anything: just take a look.

Disc omission will lead to trouble!

Look what happens when the protective hair spring disc is not installed. Need we say more?


 

**SPI 20-055-0 .00005" indicators use the same parts as model 245GA (.0001")
