A gear drive is located in the drive housing. If voltage is supplied to the starter through the ignition switch, the traction relay located in the starter housing pushes the gear along the steep thread to the flywheel ring gear. As soon as the gear reaches the stop to the spindle, there is a mechanical connection with the flywheel. The starter motor can now bring the engine up to the required RPM. If the engine is started, the gear is accelerated by the engine. For some time, it rotates faster than the starter and disengages, which leads to the termination of the connection between the starter and the engine.
Since a large current is required to start the internal combustion engine, the condition of the wire connection should be checked during vehicle maintenance. Rusted contacts must be cleaned and lubricated with protective grease used to protect battery terminals.
Attention! The procedure is given on the example of vehicles with a gasoline 8-cylinder engine without turbocharging.
Withdrawal
1. Disconnect the wire terminal «masses» (-) from the negative pole of the battery.
Attention! If the radio has an access code, then when the battery is disconnected, this code is deleted. Once the battery has been connected, the radio can only be switched on by entering the appropriate code or by using the services of an AUDI workshop or the radio manufacturer. Therefore, before disconnecting the battery, check and write down the entered code.
2. Remove the engine protection cover (see arrows in illustration).
12.2. Remove the engine cover (see arrows)
