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

Performance of full regenerative repair of assemblage of the generator with a pressure regulator lies out of limits of qualification of the average mechanic-fan. The failed generator will replace most correctly 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 support an external surface of the generator in cleanliness and not to suppose hit on it of a moisture, solvents and combustible materials.

Generator bearings jam greasing on manufacturer, are calculated on all service life of the device and additional service do not require. Brushes slide on smooth contact rings and are calculated on enough big service life. Check of a condition of brushes is made on the generator removed from the engine. Generator Valeo assembly diagramme is presented on an illustration the Assembly diagramme of the generator of firm Valeo.


1. Give a nut from an anchor shaft. At release it is possible a shaft it is necessary to keep from проворачивания by means of old drive a belt. Alternatively the shaft can be blocked with the help пруткового a key filled in an end face of a pin. The nut is thus released рожковым by a key.

2. After отдавания a fixing nut take advantage of a suitable stripper and pull together from a shaft pin приводной a pulley.
3. Take from the groove in a shaft pin segment шпонку.
4. Turn out fixing bolts and remove щеткодержатель and a pressure regulator.
5. Mark position of a plate of the holder of the bearing from an opposite side of assemblage and turn out from both cases of a coupling bolt. Separate a back cover from a lobby and easy blows of a hammer bring down last from assemblage.

6. Establish a cover with роторной assemblage (anchor) under a press and with the help 3-zahvatnogo a stripper remove an anchor. Bolts of a plate of the holder of the bearing are taken after выпрессовки a rotor - track, that stripper captures 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 in regular intervals выпрессуйте the bearing.

7. Wring out the bearing of from outside sliding rings. If the stripper is used, get its captures under an internal ring of the bearing.
8. Отпаяйте the holder диодной assemblages from статора. Wires in a soldering place between статором and a soldering iron sting should be held flat-nose pliers for the purpose of heat-conducting path maintenance, - diodes should not overheat.
9. Removal of diodes of the rectifier means presence at the executor of due qualification.

Check of a condition of coal brushes and щеткодержателей


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

3. If the length выступания 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


1. If sliding contact rings are polluted or made oily, they should be wiped the rags moistened in solvent. Scratches and other minor defects can be removed by polishing with application мелкодисперсной polishing paste. Check of a condition of isolation of a winding is made by means of an ohmmeter. Press one of probeов 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 probeа 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, breakage hence takes place. The zero indication speaks about short circuit. In both cases assemblage is subject to replacement.

Check статора


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

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

Check of diodes of the rectifier

Exact check of diodes выпрямительной assemblages on passage of a current and on a leak current can be made only by means of the special diagnostic equipment and it is necessary to charge its performance to experts of a car repair shop.


At assemblage take advantage of generator Valeo assembly diagramme (the Assembly diagramme of the generator of firm Valeo see an illustration).

Firm Mitsubishi generator

Generator Mitsubishi assembly diagramme

At dismantling, check of components and assemblage of the generator of manufacture of firm Mitsubishi (Melco) it is necessary to be guided by the assembly diagramme resulted on an illustration, and also the instructions containing in the text of the previous subsection (for firm Valeo generator). We will notice that the nominal length of brushes for the given generator makes 10 mm. Usually brushes are equipped by a label in the form of a line on which their size выступания from the directing is easily estimated.

Measurements on windings статора and роторной assemblages are made according to instructions for generators Valeo (see above) with that only a difference that resistance статорных windings should make 4 Ohm.

Firm Paris-Rhone generator

Generator Paris-Rhone assembly diagramme

Firm Paris-Rhone generator (generator Paris-Rhone Assembly diagramme see an illustration) can enter into a standard complete set of some models. Dismantling of the given generator for the purpose of replacement of brushes should be made according to the instructions resulted more low.


1. Turn out two fixing bolts and remove assemblage of a regulator of pressure.
2. Cautiously clamp the generator in a vice with soft sponges and block a shaft of a rotor by means of approaching пруткового a key (the key should be inserted into a nest in an end face of a pin of a shaft). Give a fixing nut. Remove приводной a pulley, the remote plug, шпонку and фланцевую a 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 case статора. The screw-driver should refuel not more deeply than on 2.0 mm in order to avoid damage of windings. Uncover from outside a drive together with the rotor placed in it.

5. For bearing replacement 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 assemblage about wooden брусок. The bearing should separate.

6. It is not necessary to make the further dismantling of the generator. Assemblage is made upside-down. The length выступания 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 centre workshop.
