Removal and generator installation

The car has the alternating current generator. The generator drive is carried out from a cranked shaft through клиновой a belt. Depending on car and equipment model generators of various capacity can be established. Capacity is resulted on the tablet strengthened on the generator.

If later on the car the additional equipment is established, it is necessary to check up, whether capacity of the established generator is sufficient. If necessary it is necessary to establish the generator of higher capacity.


As the storage battery can be charged only from the generator, the generator alternating voltage will be transformed by the rectifier in constant by means of a payment of diodes. The pressure regulator changes a current of gymnastics by means of inclusion and deenergizing of a current of excitation according to degree заряженности the storage battery. Simultaneously the regulator supports to constants working pressure nearby 14 In, irrespective of number of turns.

The generator is a replaceable part. The damaged generator at purchase of the new or repaired generator is set by the manufacturer off. It is necessary to hand over the old generator thus.


 REMOVAL

1 Disconnect a negative cable (-) the storage battery at the switched off ignition. The battery is in a luggage compartment behind a cover on the right side. At cars BMW 316i, 318i the battery settles down in an impellent compartment.

As a result of switching-off of the storage battery the data from memory of malfunctions of some monitors is erased. If necessary before battery switching-off it is necessary to consider the given memories of malfunctions. Address to Section Diagnostics of malfunctions. Work it is desirable to spend HUNDRED in conditions.

2 Close a negative pole of the battery to exclude possibility of casual contact.
3 Models 316i, 318i, 320i, 323i, 328i: remove a box of the air filter on всасывании, address to Section Removal and installation of the air filter of the engine.
4 Models 320i, 323i, 328i with the conditioner: Disconnect the fan with вязкостной муфтой from the pump of a cooling liquid, address to Section Removal and installation of the fan with вязкостной муфтой.
5 Models 320d: Remove radiator jalousie, address to Section Removal and radiator installation.
6 Models 320d: Before removal клинового a belt ослабьте three bolts of fastening on a pulley of the pump of the hydraulic booster of a wheel, without turning on them. After removal клинового a belt disconnect a pulley. The pump of the hydraulic booster of a wheel address to Section Removal and installation of the pump of the hydraulic booster.
7 Remove клиновой a belt, address to Section Removal, installation and a tension клинового a belt.

8 Disconnect and remove the top rejecting roller.

9 Disconnect behind the generator a ventilating hose if it is available.

10 Turn on from a generator underside a protective cap. If there are covers of nuts of joinings, remove them.

11 Uncover. Turn away a nut-1 and remove a thick cable of joining In + and thin D +. At the engine 320i, 323i, 328i расстыкуйте plug D socket + from a generator underside, having pressed thus a wire clamp.
12 Turn away a bolt-2 joinings of a negative cable.

13 Turn away fastening bolts (arrows on an illustration) and remove the generator.


 INSTALLATION

14 Models 316i, 318i: For simplification of installation of the generator press plugs-1 on an engine beam in position-2.

15 Fix the generator, having wrapped bolts of fastening by the moment 45 Н•м.

Instructions for 316i, 318i: 1 – a carving for a rejecting roller at hydraulic натяжителе клинового a belt. If it is established - the carving-1 is not used.

16 Fix the top rejecting roller.

At the engine 320i, 323i, 328i the stopper from проворачивания on the holder of a rejecting roller should enter into a groove (the marksman on an illustration) on the generator.

17 Fix a cable from an underside of the generator and join it, address to subsection "Removal". Nuts М6 are tightened by the moment 7 Н•м, nuts М8 the moment 13 Н•м.
18 Fix a cover from a generator underside.
19 Models 320d: Fix a pulley of the pump of the hydraulic booster of a wheel. After installation клинового a belt fix a pulley, address to Section Removal and installation of the pump of the hydraulic booster.
20 Establish клиновой a belt, address to Section Removal, installation and a tension клинового a belt.
21 Models 320d: Establish radiator jalousie, address to Section Removal and installation of the fan / of a casing of the fan.
22 Models 320i, 323i, 328i with the conditioner: fix the fan with вязкостной муфтой on the pump of a cooling liquid, address to Section Removal and installation of the fan with вязкостной муфтой.
23 Models 316i, 318i, 320i, 323i, 328i: Establish a box of the air filter всасывания, address to Section Removal and installation of the air filter of the engine.
