VAZ 2106 car starter - device, design features

Currently, VAZ 2106 cars are mainly equipped with a starter 35.3708 (Fig. 9.7) with an end manifold. Starters made in Germany or Belarus can be installed on some VAZ 2106 cars produced. These starters are interchangeable with starter 35.3708 in terms of their characteristics and installation dimensions. Technical characteristics of the VAZ 2106 starter Type of starter... ST-221 or 35.3708 Rated power, kW………………1.3 Current consumption at rated power, A…………………………260 (290*) Consumption current in a braked state, no more than, A... 500 (550*) Current consumption at idle (without relay)*, A, no more than.........35 (60*) ______________________ *For starter 35.3708.

In the 70-80s, the ST-221 starter with a cylindrical collector was used. This starter differed from the 35.3708 starter in the design of the rear part and the stator winding, which consisted of two shunt and two series coils (the 35.3708 starter has one shunt and three series coils in the stator winding). According to its characteristics and installation dimensions, starter 35.3708 is completely interchangeable with starter ST-221. The site discusses the repair of starter 35.3708 as the most common at present. Starter 35.3708 consists of a housing 17 with field windings (stator), an armature 19 with a drive, two covers 6 and 15 and a traction electromagnetic relay. The covers and the housing are pulled together into a single unit with two bolts (for the ST-221 starter - two studs) screwed into the cover 6. The stator has four poles 18 with winding coils. Three winding coils (serial) are connected to the armature winding in series, and one (shunt) is connected in parallel. The armature consists of a shaft, a core with winding and a collector. The armature shaft rotates in two cermet bushings, soaked in oil and pressed into the covers. At the front end of the shaft there is a starter drive, consisting of a roller overrunning clutch and gear 1. The purpose of the clutch is to transmit torque from the starter armature shaft to the flywheel ring when starting the engine, and after starting, working in overtaking mode, to prevent the transmission of torque from the flywheel to anchor. The starter electromagnetic relay is bolted to the front cover 6. The magnetic system of the relay is formed by the relay flanges, the yoke (surrounding the winding) and the core. Inside the magnetic system there is a coil of 8 relays. When the starter is turned on, armature 7 of the relay is retracted and lever 5 moves the drive with gear 1, bringing it into engagement with the flywheel ring. At the same time, plate 9 closes the contact bolts 11 of the relay, and the power to the starter windings is turned on. The starter connection diagram is shown in Fig. 9.8. When the starter is turned on, the voltage from the battery through the ignition switch is supplied to the windings of the starter traction relay (retractor P1 and retainer P2). After closing the contacts of the traction relay, the retractor winding is turned off. Useful tips To avoid many starter malfunctions, when operating it on a VAZ 2106 car, follow a number of simple rules. When starting the engine, turn on the starter for no more than 10-15 s and again after 20-30 s. Continuous long-term operation of the starter can lead to overheating of the armature and stator windings. If after three attempts the engine of a VAZ 2106 car does not start, then you should check and eliminate malfunctions in the engine power supply or ignition systems. After starting the engine, immediately turn off the starter, since prolonged rotation of the drive gear with the flywheel (especially when the choke is closed or the accelerator pedal is pressed) can lead to jamming of the starter overrunning clutch. It is not allowed to move a VAZ 2106 car using a starter. This causes significant overload and damage.

How to Remove Starter VAZ 2106 Without Pit

Removing and installing a VAZ 2106 starter The starter from a VAZ 2106 car is removed for repair or replacement, also during disassembly

The starter design requires the presence of many parts, and if one element of the starter fails, difficulties arise in starting the car engine. Repairing the VAZ 2106 starter on your own helps eliminate the problem. In most cases, a complete replacement of the starter is not required - it is enough to just repair or replace the failed part.

Gear starter StartVolt LSt 0101 for VAZ 2106.

The six is ​​equipped with a starter with a face-type collector, model 35. 3708. Sometimes German Bosch or KZATE starters with similar technical properties are installed on cars. Bosch starters have a higher cost and service life.

When the starter does not turn when you turn the ignition key, you need to exclude the possibility of a discharged battery.

Often the cause of the malfunction is a low battery charge and repair of the starter is not required.

Which starter to buy for the “six”: selection of components

The stock version of the VAZ 2106 is equipped with a gear-type electric motor, the minimum power of which is 1.4 kW/h. The design of the “six” involves the installation of higher power models up to 1.6 kW/h to make it easier to start the engine in cold weather, but in this case it will be necessary to replace the power wiring.

Note! Before installing the starter, it is recommended to check the part for compatibility - the ideal option would be to check the part number indicated on the product packaging with the vehicle VIN code. Remember, installing an electric motor with increased power can negatively affect the operational life of the power unit or cause a short circuit and output of the vehicle’s electrical systems.

Symptoms of a problem

If checking the Vaz 2106 electronics does not reveal any problems, you need to look for a breakdown in the starter. By the manifestation of the problem, you can understand which part has failed.

1. The starter spins but does not start the engine. In most cases, the starter brushes need to be replaced.
2. Clicking sound when turning the key. Repairing the starter solenoid relay should resolve the problem.
3. Frequent clicking sounds when trying to start the engine. The probable cause of the malfunction is in the starter bendix.
4. The starter continues to operate after the engine has started. There may be problems with the traction relay - the contacts have stuck together or the mechanism has jammed. It is necessary to prevent the starter from being skewed and the drive lever sticking. Check the return spring - it is located on the ignition switch.
5. Loud noise when the starter is running. Check the starter mounting. If the fastening is normal, the bushings need to be replaced.

These symptoms most often occur on Lada 2106.

Checking the solenoid relay

solenoid relay operates on the principle of an electromagnet. When voltage is applied to the windings, the pull-in relay attracts the part, which in turn extends the bendix to engage the flywheel. At the same time, the contacts close, which supply voltage to the windings. If any of the links in this chain is broken or fails, the car can only be started from the pusher.

You can check the relay either with the starter removed or directly on the car by closing it with a screwdriver or other metal object. When closed, the voltage is supplied directly to the windings, bypassing the relay. If the starter rotates, then the relay is indeed faulty.

If, when you turn the key, the solenoid relay clicks, but the starter itself does not turn, then the source of the breakdown must be looked for directly at the start.

Here are the reasons why breakdowns can occur:

1. Old age and destruction of materials
2. Winding burnout
3. Combustion of nickels inside the relay

Diagnostics

Using special instruments, you can check the serviceability of the traction relay. To check the starter without a service station, you will need a voltmeter or ammeter. One of the devices must be inserted into the starter winding power circuit. Separate the drive gear and limiter ring with a rubber gasket.

Turn on the starter and take instrument readings: with a working traction relay, the ammeter should show no more than 23A, the voltmeter should show no more than 9V. Exceeding the indicators indicates the presence of a short circuit in the wiring.

You can diagnose the wear of starter parts at home only after removing and disassembling the starter. Parts are checked for signs of wear and compliance with standards.

Starter traction relay repair

If, after all the checks, you come to the conclusion that the source of the problem really lies in the starter solenoid relay, then it needs to be repaired (although in many cases it is easier to buy a new one).

The fact is that many manufacturers, trying to make the relay as reliable as possible, make it non-separable, in which case, of course, you need to buy a new one. If the relay can be disassembled, then its operation can be restored with your own hands. Here are a few breakdowns you may encounter:

• Mechanical wire wear
• Burning nickels
• Closure

Any of the breakdowns can be seen by disassembling the relay . After repair or purchase of a new one, the part is installed in the reverse order of removal. Finally, we invite you to watch a video on the topic:

Problems when paying with bank cards

Sometimes difficulties may arise when paying with Visa/MasterCard bank cards. The most common of them:

In order to solve these problems, you need to call or write to the technical support of the bank where you are served. Bank specialists will help you resolve them and make payments.

That's basically it. The entire process of paying for a book in PDF format on car repair on our website takes 1-2 minutes.

Welcome! Starter - after all, but without it it would be difficult, because if this unit does not exist, then who will start the car? Of course, you can get out of the car, push it a little and turn on the speed and it will start, but why are such difficulties necessary? That's why a starter was invented, thanks to which the car can be started only by turning the ignition lock cylinder. But over time, this unit breaks down and therefore it has to be replaced with a new one, but not everyone knows how to replace it, and therefore we have especially prepared for you instructions in pictures on how to replace the starter on cars of the “Classic” family.

Note! To replace, you will need to stock up on: A basic set of “10” and “13” wrenches, and you will also need to take with you a screwdriver, a “10” socket and an extension for this head!

Summary:

When should you replace the starter? It needs to be changed if:

Connecting wires to the starter

Connecting a starter to a VAZ - instructions. Attach the relay in a convenient place (for example, a washer reservoir). Connect the wires to the starter. Then remove the red wire located on the flat terminal of the relay, and you need to make a connection with the connector of the male wire and the wire from the new relay.

Place the wire with a ring terminal for 8 mm on the positive side of the starter and tighten it with a nut. Place the wire of the new “female” type relay onto the contact that was released at the traction relay. This wire will transmit the positive to the coil. Using a clamp, tighten the new wire and the stock one together. Screw a small length of wire from the coil. Now you can turn on the new relay.

VAZ2107 fuse and relay diagram

The electrical wiring of the machine is protected by fuses, which are mainly installed in the central and additional units, located at the bottom of the instrument panel on the left side next to the steering column. The circuit from the battery to the terminals and connections is closed when the car ignition is turned on.

Owners of 2106 should be aware that the old design of fuses has long become obsolete, since each time they operate they overheat, which affects the density of the cells. Lack of tight contact between the fuse and the connectors leads to their burning. Therefore, replacement of the fuse blocks is necessary. To avoid unnecessary problems with the electrical wiring, you should inspect the safety devices every six months. If the contact part burns, it is necessary to replace the fuses and clean the sockets. Today, many VAZ 2106 owners are modernizing classic blocks, replacing them with modern blade fuses.
