1. Give a nut from an anchor shaft. At an otpuskaniye it is possible a shaft it is necessary to hold from a provorachivaniye by means of an old driving belt. Alternatively the shaft can be blocked by means of the prutkovy key filled in an end face of a pin. The nut is thus released by a rozhkovy key.

2. After an otdavaniye of a fixing nut use a suitable stripper and pull together from a shaft pin a driving pulley.
3. Take from the groove in a shaft pin a segment shponka.
4. Turn out fixing bolts and remove a shchetkoderzhatel and a tension regulator.
5. Mark the provision of a plate of the holder of the bearing from the opposite side of assembly and turn out from the case both coupling a bolt. Separate a back cover from a lobby and in easy blows of a hammer bring down the last from assembly.

6. Establish a cover with rotor assembly (anchor) under a press and with the help 3-захватного a stripper remove an anchor. Bolts of a plate of the holder of the bearing are taken after a rotor vypressovka - track, that captures of a stripper were got under a plate of the holder of the bearing. If the bearing is subject to extraction from a guard, turn out internal bolts and evenly выпрессуйте the bearing.

7. Wring out the bearing from sliding rings. If the stripper is used, get its captures under an internal ring of the bearing.
8. Otpayayte the holder of diode assembly from a stator. Wires between a stator and a sting of a soldering iron should be kept in a soldering place flat-nose pliers for the purpose of providing a heat-conducting path, - diodes should not overheat.
9. Removal of diodes of the rectifier means existence at the performer of due qualification.

1. Estimate quality of contact of coal brushes with sliding rings.
2. Check freedom of a course of brushes in directing, in case of need smooth out fastenings.

3. If the length of a vystupaniye of brushes makes less than 0.5 mm, they are subject to replacement. Measurement is made by means of a ruler.

1. If sliding contact rings are polluted or greasy, they should be wiped the rags moistened in solvent. Scratches and other minor defects can be removed with a polishing way with application of melkodispersny polishing paste. Check of a condition of isolation of a winding is made by means of an ohmmeter. Press one of щупов a measuring instrument to the core of the rotor, the second - to a contact ring. If the ohmmeter shows infinity, it is necessary to replace a rotor.

2. For stock-taking of conductivity of a winding connect both щупа an ohmmeter to contact rings. The demanded range of measurements lies in limits from 3.4 Ohm to 3.7 Ohm. If the device registers infinite resistance, break therefore takes place. The zero indication speaks about short circuit. In both cases assembly is subject to replacement.

1. Short circuit of windings of a stator usually is caused by an overheat of assembly and comes to light already during visual check. In the absence of visible signs of damages press one щуп an ohmmeter to lamellar rings, and the second - serially to each of three wires of a stator.

2. For check of windings of a stator on conductivity existence serially probe an ohmmeter each of pairs of windings (1-2, 1-3 and 2-3). Absence of indications testifies to chain break. Normal value lies within a range of 0.10 ÷ 0.11 Ohm.

1. Turn out two fixing bolts and remove assembly of a regulator of tension.
2. Carefully clamp the generator in a vice with soft sponges and block a rotor shaft by means of a suitable prutkovy key (the key should be inserted into a nest in an end face of a pin of a shaft). Give a fixing nut. Remove a driving pulley, the remote plug, a shponka and a flange washer.
3. Turn out long through bolts from a forward part of the generator.

4. By means of a screw-driver wring out a forward cover from the stator case. The screw-driver should refuel not more deeply than on 2.0 mm in order to avoid damage of windings. Uncover the drive party together with the rotor placed in it.

5. For replacement of the bearing turn out four fixing bolts from the face party of a cover, then undertake a cover and a rotor, as is shown in an illustration, and knock with assembly about wooden whetstone. The bearing should separate.

6. It is not necessary to make further dismantling of the generator. Assembly is made upside-down. The length of a vystupaniye of brushes is measured, as well as on other generators, by means of a ruler. Soldering of new brushes demands special accuracy should be made in the conditions of a car-care center workshop.
