On an illustration the starter (the 5-cylinder engine) in the disassembled kind is shown

1 – the holder of brushes;
2 – an anchor;
3 – a reducer;
4 – the case of the bearing involving;

5 – the case

7 – a bearing cover;
8 – a lock washer, an adjusting washer and a sealing lining.

Engine start


  1. At ignition key turn in position Start a food arrives on the plug 50 involving relays, located from above on a starter.
  2. Thus the inclusion lever enters a starter gear wheel on spiral coils into gearing with a gear wreath of a flywheel of the engine.
  3. Only after full gearing of a gear wheel the involving relay includes 30 food of the accumulator completely arriving from the plug and then the starter strongly scrolls the engine.
  4. The engine of a starter and gear wheel are connected among themselves through a reducer. Therefore the electric motor rotates much faster, than a gear wheel.
  5. When the engine is started – the gear wheel again leaves gearing with a flywheel.

Starter removal


  1. To disconnect a wire of "weight" from the accumulator, danger of occurrence of short circuit otherwise is great.
  2. To remove the bottom protection of a motor compartment (the head body Elements).
  3. To lift the car in front on the right and to fix.
  4. To remove all wires from the involving relay.
  5. To remove starter fastening in front in a movement direction (there where it is).

  4. To remove both screws (or nuts hairpins) from a back cover of the case and to uncover.
  5. To measure length of brushes – the minimum length of 8 mm.
  6. For replacement of brushes to disconnect a fixing plate from the involving relay.
  7. Again to collect a starter, thus загерметизировать a case cover, fixing screws and a bearing cover.

Removal of the involving relay


  1. To remove a starter.
  2. To disconnect a wire from a starter.
  3. To unscrew three screws on a fixing flange of the involving relay.
  4. A few to wring out involving relay and to take out an eye from the lever of inclusion of a starter.
