Dismantling and generator assembly, check of a condition of internal components

Performance of complete regenerative repair of assembly of the generator with a regulator of tension lies outside the limits of qualification of the average amateur mechanic. It will be most correct to replace the failed generator with the new or restored block. Replacement of brushes and other small repair of the generator should be made in the conditions of a workshop. Try to keep an external surface of the generator clean and not to allow hit on it of moisture, solvents and combustible materials.

Dismantling

Bearings of the generator jam greasing at manufacturer, are calculated on all service life of the device and additional service do not need. Brushes slide on smooth contact rings and are calculated on rather big service life. Check of a condition of brushes is made on the generator removed from the engine. Assembly diagram of the Valeo generator is presented on an illustration Assembly diagram of the generator of Valeo firm.

 PERFORMANCE ORDER

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.

Check of a condition of coal brushes and shchetkoderzhatel

 PERFORMANCE ORDER

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.

Check of a condition of a rotor

 PERFORMANCE ORDER

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.

Stator check

 PERFORMANCE ORDER

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.

Check of diodes of the rectifier

Exact check of diodes of vypryamitelny assembly on passing of a current and on a current of leak can be made only by means of the special diagnostic equipment and it is necessary to charge its performance to specialists of car repair shop.

Assembly

At assembly use assembly diagram of the Valeo generator (see an illustration Assembly diagram of the generator of Valeo firm).

Mitsubishi firm generator


Assembly diagram of the Mitsubishi generator

During the dismantling, check of components and assembly of the generator of production of Mitsubishi firm (Melco) it is necessary to be guided by the assembly diagram given on an illustration, and also the instructions containing in the text of the previous subsection (for the Valeo firm generator). Let's notice that the nominal length of brushes for this generator makes 10 mm. Usually brushes are equipped with a label in the form of the line on which the size of their vystupaniye from the directing is easily estimated.

Measurements on windings of a stator and rotor assembly are made according to instructions for Valeo generators (see above) with that only a difference that resistance of statorny windings should make 4 Ohm.

Paris-Rhone firm generator


Assembly diagram of the Paris-Rhone generator

The Paris-Rhone firm generator can enter into a standard complete set of some models (see an illustration Assembly diagram of the Paris-Rhone generator). Dismantling of this generator for the purpose of replacement of brushes should be made according to the instructions provided below.

 PERFORMANCE ORDER

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.
