Dial indicator (BMW X3 E83)

The dial indicator is designed to measure linear dimensions using absolute and relative methods, to determine the magnitude of deviations from a given geometric shape and the relative position of surfaces. Indicators with a measuring range of 0-2 mm are available in two versions:

ICh - with the movement of the measuring rod parallel to the scale;

IT - with the movement of the measuring rod perpendicular to the scale.

The indicators are mounted either by a connecting sleeve with a diameter of Sh7, or by a 5 mm thick eye with a connecting hole with a diameter of 5 mm.

The uses of the hour indicator are quite varied and are therefore not described here. Specific cases of using the device are described in the repair manual (for example, measuring the axial play of the engine crankshaft, measuring the runout of the brake disc, etc.).
