Starter on the car VAZ 2108, to the great regret holders of "eights", breaks down quite often. Each time to go to the service station at his failure, of course, foolish, and therefore, it is necessary to learn how to repair the item. About this further in the article.

Starter 2108, and the device designation

Fastening screw of the protective hood (1), a protective cap (2), the locking half-ring (3), a fastening nut of the back cover (4), back cover (5), the brush spring (6), guiding the brushes (outer part) (7) brushes (8) and the stator (9), the anchor (10), a drive lever (11), the actuator (12), a limiting ring (13), retaining ring (14), the actuator arm axis (15), fixing screws traction relay ( 16), front cover (17) sealing ring of the cover (plastic) (18), tie rods (19), a rubber plug (20), the core of magnetic switch (21), a return spring (22), ring seals magnetic switch (23 ), magnetic switch (24), sealing washer (25), shims (26).

The starter is a device that is designed to convert electrical energy into mechanical energy with the purpose of starting the engine. In fact, the starter motor is an electric motor DC.

Starter VAZ 2108, signs of malfunction

There are a number of signs of a starter malfunction by car VAZ 2108:

1. The starter does not twist the motor. During the turn of the ignition key, the anchor does not rotate, and the retractor relay does not work. After starting the power unit, the starter is not turned off. These symptoms, as a rule, indicate the failure of the driving relay winding.
   
2. The starter motor turns slowly. While turning on the starter, the crankshaft slowly turns. Most often, it indicates a malfunction of the brushes of the starter, manifold, stator or anchor winding.
3. The starter works, however the crankshaft does not rotate. In this case, most likely, the problem with the Bendix starter.

Why frequently breaking the starter in 2108

Starter is a short-term motor. When it is in good condition, and the battery gives a high-quality current, the device starts lasting a few seconds. It is impossible to function for a long time, so drivers who like to "drive" the starter must be abandoned by such a habit and apply it only as manufacturers advise.

As practice is evidenced, repair and replacement of the starter on the VAZ 2108 is often required in cases where the auto owner strongly overloads it or runs with a weak battery. In addition, the output of the starter can be associated with those or other problems that are due to malfunctions of the vehicle power unit.

That negatively affects the starter performance

Typically, starter problems occur in the winter. At negative temperatures, he has to experience extremely high loads. If the device is old, it simply refuses to function, which is not surprising, because it perceives a large current load, which is 450 ampere. This current causes the individual common starter breakage, where the contacts are burning on the relay relay. In this case, we are talking about placing wires that are connected to the stator motor and the "plus" of the battery.

Why burn contacts, how to fix

It is impossible to avoid burning contacts during the operation of the car, since it constantly passes through the power chains a large current. Accordingly, only one output remains - repairing the relay according to the following scheme, to clean the contacts, thereby restoring the performance of the starter.

Tools, fixtures, consumables

1. Ommeter.
2. Figured screwdriver.
   
3. The key to "10".
4. Small sandpaper.
5. Set of wrenches.

How to ring the starter, which indicates the need to replace the starter

The implementation scheme of this event is very simple, it is necessary to put the starting windings upwards, i.e. on the end, after which we produce such actions: one end of the wire we join the mechanism bolts, the second to the positive terminal, then start the device.

If the mechanism after starting does not twist at all either turns badly, boldly take it for its repair. But if the device works normally, it means there is no need to disassemble it, most likely, the reason for a bad start consists in another component of the vehicle.

In addition, it will be worthwhile to check the mechanism relay. In this situation, the inspection scheme is elementary:

1. We apply "minus" to the relay case.
2. We supply 12-volt voltage to the output.
3. We connect the contact bolts.

If sparks appeared on the contact bolts, and the clutch moves into the hole, which means the relay is properly. The lack of specified phenomena and voltage jumps on the device will indicate that it is necessary to replace the relay, since the starter does not twist because of it.

Starter 2108, how to replace it, step by step instruction

1. First of all, disconnect the terminals from the starter.
   
2. Next, unscrew the nut with the relay and dismantle the wiring block.
   
3. Then dismantle the protection of the motor crankcase.
   
4. Now we unscrew the starter mounting nuts.
   
5. Next, unscrew the top mounter mounting nut.
   
6. Gently remove the starter outward.
   
7. New starter mount in reverse order.

How to disassemble the VAZ 2108 starter, how to replace brushes, sleeves, anchors

To disassemble the starter, do the following:

1. Using the key to "10", we unscrew the two nuts of the studs.
2. Together with anchor, we get the device you want.
3. From the tree anchor we remove the main gear.
   
4. Using a curly screwdriver, we unscrew two screws from the back cover.
5. Remove the lid.
6. Take out the brushes and take an anchor from the stator.
7. With anchor, remove the special adjustment washer and the owl of the shaft.

Now parse drive gear and the drive itself, and then separate the lever from the support for access to all the internal parts of the starter (armature winding, brushes and brush holder, bushings, etc.). On the elements of the mechanism should not be a trace of charring and workable collector and windings should always be clean, without various contaminants.

When needs change sleeve. In the presence of small cracks in the reservoir, process them fine "sandpaper". If the anchor burned or badly worn, change it to a new one. If the shaft journal bearings have a teaser or galling, process them "sandpaper" with fine grain. As for brushes, it wears you must replace them with the brush holder. It should be noted that the wear is visible at once. After all maintenance activities are carried out starter assembly.

Tips Prof.

As you can see, the repair and replacement of the starter - exercise time-consuming enough, but in this case, is not difficult. But if you doubt their abilities, it is advisable to contact the service station. Good luck!
