Generator
Dismantling | 1. Remove the four coupling bolts.  | 2. Insert a flat blade screwdriver between the two front cover and the yoke of the stator and remove the cover. |
 |  | Do not insert a screwdriver too deep, as this may damage the stator windings The back cover can be removed with difficulty, because it uses the ring, locking the outer ring of the rear bearing. To facilitate the removal of the rear cover its soldering heat capacity of 200 watts. Do not use a hair dryer to heat, as this may damage the unit diodes. |
|
 | 3. Secure the rotor is in the grip of the pulley up. | Replace the jaws soft protectors to avoid damage to the generator components. |
|
4. Remove the pulley nut, then remove the spring washer, a pulley and the spacer.
5. Remove the front cover and two washers.
6. Remove the rotor from the vise.
7. Remove the screws that secure the brush holder, the rectifier and nuts Terminal B.
8. Remove the stator and the back cover.
9. Separate the slinger from the brush holder.  | 10. Desolder three wires from the diode and remove the stator. | When otpaivanii make sure that heat of soldering was not passed diodes. On exert great efforts to diodes. |
|
11. The separation of the rectifier from brush holder Unsolder two plates are soldered to the rectifier. |
|
Check Rotor |  | 1. An ohmmeter measure resistance between contact rings. If the resistance is extremely low, so there is a short circuit in the rotor winding. If the conductivity does not appear, there is a breakage in the rotor winding, and the need to replace the rotor. Resistance: 3.1 ohms |
 | 2. An ohmmeter check up conductivity between the contact ring and the anchor of the rotor. In the presence of conductivity, replace a rotor. |
|
|
Stator |  | 1. An ohmmeter check up conductivity between the wires of the stator coils. In the absence of conductivity, replace the stator. |
 | 2. An ohmmeter check up conductivity between the stator coils. In the presence of conductivity, replace the stator. |
|
|
Check rectifier unit |  | 1. Check for continuity between the positive pole of the rectifier and the output terminal of the stator coil. The ohmmeter should show conductivity in one direction only. If the conductivity is available in both directions, then broken and the rectifier diode must be replaced. |
 | 2. Check for continuity between the negative pole of the rectifier and the output terminal of the stator coil. The ohmmeter should show conductivity in one direction only. If the conductivity is available in both directions, then broken and the rectifier diode must be replaced. |
 | 3. An ohmmeter check up conductivity between the outputs of each of the three diodes. The ohmmeter should show conductivity in one direction only. If the conductivity is available in both directions, then broken and the rectifier diode must be replaced. |
|
|
Replacement brush |  | 1 If brushes are worn to the maximum allowable length, replace them. The minimum allowable protrusion of the brush: 2 mm |
2. Unsolder braided wire and remove the spring and brush.
3. Install the spring and the new brush brush into the brush holder. Solder the braided wire to brush holder. |
|
Assembly |  | 1. The assembly is carried out in sequence, return dismantling taking into account the following. 2. Before connecting the rotor to the back cover, insert the wire through the small hole in the back cover to lock the brush in the retracted position. After installing the rotor, remove the wire. |
