The starter housing houses the drive, poles and collector. An anchor, a collector, and a brush holder are located in the body of the poles and the collector. The brush holder contains carbon brushes, which are wear parts and wear slowly but constantly. With a large wear of the brushes, the normal operation of the starter is not ensured.
The drive gear is located in the front of the housing. When voltage is applied to the starter through the ignition switch, the traction relay is activated and the toothed gear is displaced along the oblique thread along the shaft until it stops in engagement with the flywheel ring gear. This ensures that the engine can be rotated from the starter at a sufficient number of revolutions. When the internal combustion engine starts, the starter gear begins to rotate faster from the engine and disengages from the flywheel, breaking the mechanical connection between the starter and the engine.
