1. Unscrew the nut on the lower contact bolt of the traction relay and disconnect the output of the stator windings from it.
2. Turn away nuts of fastening of the traction relay and remove it.
3. For the ST-221 starter, loosen the screw securing the tightening protective tape on the cover 11 (see fig. Starter parts) from the collector side and remove the tape 9 with the gasket. Turn out screws of fastening of plugs of brushes and remove brushes.
4. At the starter 35.3708, unscrew the screws and remove the protective cover 3 (see fig. Details of the back of the starter 35.3708). Unscrew the screws securing the stator winding leads to the brush holders, remove the springs 2 and brushes 1. Remove the lock washer 4.
5. Starter ST-221 (see fig. Starter parts) unscrew the nuts of the tie rods 16 (on the starter 35.3708 unscrew the coupling bolts) and disconnect body 15 with cover 11 from cover 1 with anchor 17. Unscrew tie rods from cover 1. Detach the manifold side cover from the housing.
