After disassembling the starter, you should check:
- the condition of the brushes, their wear, and the freedom of movement of the brushes in the brush holders;
- the pressing force and position of the brush springs;
- a type of collector that should be cleaned with a rag soaked in gasoline or trichloroethylene and sanded with fine-grained sandpaper;
- condition of self-lubricating bearing bushings; if replacement is necessary, new bushings should be soaked in engine oil (SAE 30 or 40 viscosity) for at least 20 minutes before installing them in the starter.
Checking the electromagnetic starter
1. Disconnect the ground wire from the battery and all wires from the electromagnetic starter.

2. Connect the battery with a 3 W test lamp connected in series to the housing and the power connector of the electromagnetic starter winding (1 - threaded contact for connecting the wire from the battery, 2 - threaded contact to the starter motor, 3 - power connector of the electromagnetic starter winding).
3. If there is no break in the winding, the light bulb should light.

4. To check the starter contacts, connect the battery with a 12–21 W test lamp connected in series to the threaded contacts of the electromagnetic starter and an additional wire to the power connector of the electromagnetic starter winding (1 - threaded contact for connecting the wire from the battery, 2 - threaded contact to the starter electric motor, 3 - power connector of the electromagnetic starter winding).
5. When connecting an additional wire to the power connector of the electromagnetic starter winding, the electromagnetic starter should operate and the light should come on.
