REPAIR



On cars UAZ-3160,-31601 and-31605 generators of two types can be installed: 665.3701 or 16.3771 variable currents with the built-in integrated regulator of tension.
On the car UAZ-31604 the generator of alternating current of BOSCH with the built-in integrated regulator of tension is used.

Fig. 269. Generator 665.3701: 1 – pulley; 2 – plug; 3 – forward ball-bearing; 4 – fan;
5 – a cover from the drive; 6 – the washer is persistent; 7 – rotor winding; 8 – stator; 9 – stator winding; 10 – polar tip of a rotor; 11 – rotor shaft; 12 – a cover from contact rings;
13 – contact ring; 14 – back ball-bearing; 15 – conclusion "+" generator; 16 – condenser;
17 – conclusion "Д" of the generator; 18 – conclusion "Ф" of the generator; 19 – tension regulator; 20 – casing


The device of the generator 665.3701 is shown in fig. 269.
The generator fastens to the engine block on an arm from the right party and is given to rotation by means of a wedge-shaped belt from a pulley of a bent shaft.
In use check operation of the generator according to the indication of the voltmeter and by means of a control lamp of a discharge of the rechargeable battery.
