17:12. Replacement of a rope of the drive of a speedometerOn cars of the SAAB brand two types of mechanisms of the drive of a speedometer are established. The cars manufactured till 1987 were equipped with ordinary trosikovy drives which carried out rotation of a speedometer remotely, by means of a rope with the rotating flexible internal shaft.
Uncertain, changeable indications of a speedometer, such as pulling of an arrow or its gallop, usually result from wear of a driving rope of a speedometer.
The cars released after 1987 are equipped with the electronic sensor on the place of a driving gear wheel. This device measures the speed of rotation of the main transfer of transmission and will transform information to the electric signal sent then in the speedometer module on an instrument guard. The signal is also used as introduction information of the electronic actuation device of a control system of the engine (and, there where are available - the electronic actuation device of a tempostat, the traveling computer and the electronic actuation device of the traction control system).
Installation into placeInstallation of a rope of the drive of a speedometer is into place carried out as it should be, the return to a removal order. Carry out laying of a new rope in the forward panel in the same way as laying of old was carried out, watching that it did not concern moving components. Avoid formation of hard loops on a rope as loops worsen efficiency of rotation of the core of a rope.
