We independently remove the starter from a Chevrolet Niva car

Sometimes it happens that a car enthusiast, having overcome some particularly deep puddle, discovers that the car has stopped starting. This can happen with any car, but it happens especially often with the Chevrolet Niva. We will tell the reader how to independently remove the starter from this machine in this article.

Preliminary diagnosis

Before dismantling the starter, you must make sure that this device is the cause of the malfunction. This can be done visually or by replacing the battery with a working one. It is also worth checking whether current passes from the battery to the starter: if current passes, then the cause of the malfunction is the starter, but if current does not pass, then the starter relay should be checked. If the latter malfunctions, it must be replaced. If everything works, then the next step is to remove the starter.

DIY repair

After removing the Chevrolet Niva starter, you can try to repair it yourself or at a specialized service. If you have experience working with a similar mechanism and are confident that the cause is, for example, a faulty retractor relay, then everything is quite simple. It is enough to remove the cover from the relay and clean the contact plates. But to be completely sure, especially since the unit has already been removed, it is advisable to check it on a stand under load, because it can work properly when idling, but not when under load.

Another malfunction may be damage to the planetary mechanism, which has plastic parts. Its damage can be seen by disassembling the starter into two halves. To do this, simply unscrew the two nuts from the back of the unit and split it in half.

According to reviews, the Chevrolet Niva starter cannot be repaired, since spare parts for it cannot be purchased. But time passes, everything changes, it is possible that this is no longer the case. However, after repair or replacement, it is installed in the reverse order.

It is imperative to clean and lubricate the wires suitable for the starter, having first checked them for conductivity. If necessary, the power wire will need to be replaced, as it may be one of the reasons for poor starter performance.

How to remove the Niva Chevrolet starter

To remove the starter, you need to do the following:

1. Disconnect the wires from the battery and starter (you can use a wrench of the required size).
2. We unscrew the starter, which is attached with three bolts to the box body. You can remove it through the top or bottom, however, motorists believe that it is more convenient to remove it through the bottom. It's difficult to do this without a pit. Air conditioning can be another obstacle. If it is present, you will also need to remove the warm air intake hose. The clamp that secures it to the engine can be loosened using a flathead screwdriver.

Now you need to determine the cause of the failure. There may be several of them:

1. Faulty brushes. If they are worn out and do not reach the anchor, they should be replaced.
2. Faulty retractor. In this case, replacement is necessary.
3. Knocked out guide bushings also require replacement.
4. The cause of the breakdown may be a burnt-out winding or a burnt-out armature. It is difficult to repair such a malfunction at home; it is better to contact a specialist.

The wires leading to the starter need to be cleaned and lubricated, and also checked to see if current is flowing through them. If necessary, it is better to replace the power cord, because it can cause poor operation of the device.

If the cause of the breakdown is identified and eliminated, then the next step is to install the starter. You need to do this in reverse order:

• Connect the wires first, then mount the starter and tighten the three bolts;
• screw back the rod that covered the starter outlet and the engine protection;
• connect the battery and check if everything works.

The starter does not start the crankshaft

If the starter rotates, but the engine does not run, experts recommend checking the condition of the teeth on the flywheel and Bendix gear. When a car is used intensively, these teeth can become critically worn. Check their condition through the special mounting hole. You can replace them by purchasing a recompilation kit for the Niva Chevrolet starter. Its cost is about 500 rubles.

At idle the same symptoms also appear. If the starter gear fits well into the engine flywheel but does not rotate, check the starter for wear and other mechanical damage. The unit may not be installed correctly.

When it comes to starter repair kits for Chevrolet Niva vehicles, they can vary greatly in their equipment and prices. But most often, manufacturers take into account all the parts that are subject to wear and need to be replaced.

Recommendations for using the starter

To make your starter last longer, you need to follow a few simple recommendations:

1. If you turn on the engine, then this should be done no longer than 15-20 seconds, and repeated no earlier than after 25-30 seconds. If after three times the engine does not start, you need to check the ignition and power system. If such faults are detected, they must be corrected.
2. Do not use the starter to move the vehicle. This puts a lot of stress on the trigger mechanism.
3. If you have successfully started the engine, turn off the starter, as the overrunning clutch may jam due to frequent rotation of the starter drive gear by the flywheel.

Anyone who has already removed and installed the starter at least once is unlikely to want to do it a second time. Although this work is not difficult, it requires a lot of effort and sometimes money. Follow these simple rules to avoid such breakdowns.

Why is starter protection needed on Niva Chevrolet?

Apparently the engineers thought that the thermal protection of the starter should remind of itself, so they made such a short-lived mount. Due to the fact that the protection flies off the eye, a nasty rattling sound appears.

The layout of the attachments under the Niva's hood was clearly adapted to the shape of the wheel arches, so some components remained out of reach. Starter, including. The exhaust manifold hangs above it, from below it is covered with a mudguard and front axle protection and sandwiched between the engine support cushion and the pump.

Ingenuity + spring = Russian know-how!

The shield is attached to two nuts and is a casing stamped to the shape of the starter. Its task is to protect the starter from overheating , since in injection engines with a catalyst the temperature of the exhaust manifold is an order of magnitude higher than in carburetor engines.

Danger of driving without starter protection

The danger of driving without a protective shield is that under high loads and in difficult operating conditions, the starter can critically overheat, which will lead to melting or cracking of plastic parts , insulation on the windings, as well as burnout of the insulation on the wires that power and control the starter.

As a result, this can lead not only to failure of the starter, but also to a short circuit in the wires, then you will have to become familiar with the principle of operation of the fire extinguisher. The main problem with the shield is that the mounting lugs are secured by two spot welding points . After a year or two of use, they inevitably fall off due to vibration and the casing begins to rattle and ring, which few people like. Hello engineers, now let’s remove the starter protection on the Chevrolet Niva.

Causes and symptoms of starter malfunctions

The causes of malfunction or poor performance of the starter may be:

• winding damage;
• faulty (erased) brushes, due to which they no longer reach the anchor;
• oxidation and burnout of contacts and battery terminals (removed by lubrication with Vaseline);
• retractor malfunction;
• hull destruction;
• malfunction or discharge of the battery (the problem is resolved by charging or replacing the battery);
• the presence of severe wear on the armature with the spring;
• knocked out guide bushings.

Reference! Since the starter is enclosed in a solid housing, if it breaks down, it is not advisable to repair it - it is necessary to replace this part of the car.

Signs of a starter malfunction or failure:

• the bendix (overrunning clutch) does not return when starting the Niva engine, as evidenced by the buzzing sounds under the hood;
• when turning the ignition key, the driver hears something clicking, but the car’s retractor does not rotate;
• An attempt to start the car results in a strange “unhealthy” squeal or squeak coming from under the hood, but it does not turn on.

How to remove the starter thermal cover on a Chevrolet Niva

Based on the experience of Chevrolet Niva owners, it turns out that there are two ways to dismantle the ill-fated casing - pick it out with a pry bar and dispose of it, but then the starter will be left without protection, or spend several hours dismantling it.

The starter is more expensive, so we proceed to dismantling using this technology:

1. It is imperative to de-energize the car by disconnecting the negative terminal of the battery or turning off the mains switch.
2. Remove the engine protection. To do this, you need to install the car on a viewing hole or a lift.

Remove the engine protection.

Now that we have the casing in our hands, we assess the degree of damage - if the eyes are simply broken off, we can either weld them well to the casing or put them on bolts, this is more reliable.

Some recommend laying a layer of asbestos between the starter and the shield , but if there is a gap in this place, you can count on some kind of cooling. Before putting the starter protection in place, you need to make sure that you have new exhaust pipe gaskets (on the manifold side and on the muffler side) and new bolts and nuts on hand. Only now you can put everything back together in reverse order.

Option without air conditioning

In some cases (if the car does not have air conditioning), you can do without dismantling the exhaust pipe. To do this, you need to unscrew the engine mount and jack it up, resting one end of a wooden block on the exhaust manifold closer to the cylinder block, and the other on the jack.

So you can try to bring the heat shield back, besides this there is another way - dismantling the exhaust manifold. Without a collector, the shield can be easily removed.

Good luck to everyone and enjoy your travels!

Replacement

If you are wondering how to remove the starter on a Chevrolet Niva, then you will find the answer to this question below:

1. First of all, to prevent a short circuit, disconnect the battery
2. The crankcase has a protection that needs to be removed
3. Unscrew several bolts that secure the starter.
4. Removing thermal protection

5. Pull the part to be replaced towards you and disconnect the wires from it

6. We clean the power wires since they could be the cause of unstable operation

When the part has been removed, you can diagnose it and try to repair it. If you decide to try to make repairs, first of all pay attention to the planetary mechanism; you can understand the condition of the parts of this unit by disassembling it; just unscrew a few bolts. Most craftsmen claim that this mechanism cannot be repaired and in case of breakdown it is better to immediately replace it with a new one.

When unscrewing, the 82-piece tool set helped a lot:

The contents of all of these are the same, the difference is in the layout of the suitcase. We used both ratchets and all their extensions and universal joints so that we could reach the bottom bolts and a “13-socket” for the top bolt.

I removed the “-” from the battery. I unscrewed the bolts and lowered them a little to make it easier to unscrew the wires:

I pulled this miracle down: it really squeezes between the suspension parts)) And now let’s compare...

Not a very good angle: the original starter is closer to the phone, because of this its size is slightly exaggerated. In reality, it is noticeably smaller - both shorter in length and smaller in diameter.

Here he is - dear (closer):

For reference, power characteristics: Pramo - 1.4 kW, KZATE - 1.55 kW.

We install a new miracle in the same sequence and... nothing happens. Because the new KZATE is bigger - it doesn’t interfere from any side. I had to lower (unscrew) my pants =)

As a result, the new starter is in place, it seems to turn more powerfully than the old one, but for a longer time. The squeal is gone)) Don't break! All blessings!

Replacing the starter on a Chevrolet Niva

Before I started replacing the starter, I disconnected the battery. First, I removed the entire lower engine protection.

The starter is secured with three bolts; after they are unscrewed, it can be pulled out from below the engine, but a rod will interfere with this. So I immediately unscrewed it.

First the nut from the bottom.

Then the bolt on top.

Now you can unscrew the starter. The bottom bolt is fairly easily accessible from below. I unscrewed it with a small ratchet.

I unscrewed the remaining two bolts from above. This is what the starter looks like from above.

Here I have already used a spanner wrench. The key part of the key is slightly bent, otherwise it would be impossible to get to these bolts. The middle bolt is also more or less accessible.

The top bolt is the most difficult to reach of the three. But in principle, the key was easy to throw onto it, only the key stroke was very small and it took a long time to turn.

When all three bolts were unscrewed, the starter easily came out of its place.

But in order to get it out of there, the protection of the starter from heat interfered. These are sheets of metal around it. On the side of the box, the starter rested against the protection with its protrusions into which bolts were screwed. At this point I simply bent the protection with my hands. On the other side, the protection at the bottom is secured with a nut. I tried to unscrew it with a large ratchet. She didn't give in. Then I pressed a little harder and it seemed to turn. And when I looked, I saw that the nut did not even think of turning away, but I simply twisted the eye to which it was attached. True, the protection bent back and allowed the starter to be removed, and the mount itself did not break off at all and seemed to be holding tightly and not rattling. I then left it all like that.

(It turns out I was wrong here. The nut shouldn’t have been unscrewed; it is welded to the mount. But you need to unscrew the bolt that goes into this nut on the other side.)

Now the starter easily pulled out of its place. The wires that go to the starter allow you to remove it without disconnecting them.

There are only 2 wires going to the starter. One small red one, which is simply plugged into the connector. We easily disconnect it by pulling the connector. The second one is healthy, screwed on with a nut covered with a rubber nozzle, and by unscrewing it I completely removed the starter.

Having unscrewed two nuts from the back of the starter, I disconnected its two halves and saw this picture.

It turned out that inside it there is a plastic part in the form of a glass with teeth, along which three gears run. So it broke into pieces and these gears therefore did not run in a circle and therefore did not rotate the gear that meshes with the flywheel.

And the gear that turns them also lost one tooth, but most likely this is due to flying plastic fragments.

This photo report shows in detail how to replace the starter on a Chevrolet Niva with your own hands. It is worth noting that replacing the starter is quite a rare need. In 80% of cases the starter can be repaired. In our case, there was a mechanical failure of one of the starter drive gears. This spare part is not sold separately, so I had to replace it with a new starter.

There is nothing complicated in the starter replacement procedure. He can handle it quite well on his own. Tools you will need :

• Ratchet wrench and sockets for 10, 12;
• Phillips and flathead screwdrivers;
• A penetrating lubricant like WD-40 may be needed;

also recommend that you familiarize yourself with our video about starter malfunctions and the main possible causes.

What tools are needed for removal?

To replace, you will need the following sets of tools and accessories::

• medium-sized flat-head screwdriver;
• open-end wrenches;
• socket heads equipped with a ratchet collar;
• special penetrating lubricant WD-40 (may not be useful);
• spanners.

When all the specified tools are prepared, you can begin the process of removing the old starter and replacing it with a new one according to the algorithm below.

How to replace the starter on a Niva Chevrolet

It may happen that the Chevrolet Niva does not start, or starts, but with periodic interruptions. This may be due to a failure, for example, of the electrical or fuel system. The most common failure is when the starter fails. But in order to correctly and fully carry out diagnostics, it is necessary to remove the starter; the Chevrolet Niva is no exception.

This device is an electric motor with direct current, which is activated by a permanent magnet, which is combined with a planetary gearbox, plus a two-winding electromagnetic relay. Therefore, before dismantling, you should understand whether this is the reason that the engine does not want to start. This can be determined both visually and by replacing the battery.

Node location

The starter is an electric motor powered by direct current. It is combined with a planetary gearbox and operates due to the action of magnets. The autostarter is also combined with an electromagnetic traction relay located in a double winding.

If the Chevy Niva does not start and the starter does not turn, you should first make sure that this particular unit is faulty . To do this, carry out preliminary diagnostics: just check the contacts of the ground and positive wires (located on the back of the device). In addition, it is worth trying to close the starter contacts using a screwdriver. If the device does not work even after this, it definitely needs to be replaced.

To find the starter in a Chevrolet Niva car, you need to open the hood . Pay attention to the engine: the autostarter will be located to the left of it. The top of this unit is covered with a special heat-protective casing, so you won’t be able to see the starter right away. You can try to see this unit from below the car, but the starter protection will prevent this from happening. For the reasons described above, in order to inspect and replace the device, you will first have to remove the specified parts.

Preliminary diagnostics

A number of actions need to be taken:

1. We check all the existing electrical connections that connect the starter and the battery, since it happens that poor contact between ground and positive leads to poor operation of the device, and the click of the retractor relay is heard, thereby not enough power to crank the crankshaft in the engine. This problem is eliminated by cleaning the contacts of the starter, battery, and various groups of contacts.
2. We check the battery itself; it is necessary to replace the load plug itself with a proven one that is working. If there is no result, then it is necessary to remove the unit and replace it.

Instructions for a complete diagnosis of the starter

The starter does not transmit torque to the crankshaft

Replacing and removing the starter on a Chevrolet Niva

To make a replacement you must:

1. We disconnect the terminals from the battery; if this is not done, a short circuit may occur, which will lead to a complete replacement of the electrical wiring

2. Using a ratchet wrench, remove the crankcase protection
3. Loosen the three bolts that secure the starter.
4. We dismantle thermal protection
5. Together with the wires, carefully pull out the unit; after pulling it out, carefully pull the wires toward you and disconnect them from the device.

6. The power wires that are connected can be cleaned; perhaps the reason that the engine starts unstably lies in poor contact.

After it has been removed, diagnostics and subsequent repairs can be made.

Retractor

To ensure that the starter does not experience additional loads, a special Niva Chevrolet starter relay is installed, it is also called a solenoid relay, consisting of:

• Two windings
• Magnet
• Anchors
• Springs

When power begins to flow, the armature, under the influence of an electromagnetic field, begins to compress the spring, which leads to the rotation of the bendix. When the engine starts, the power is turned off and the spring relaxes.

Malfunctions

• Burnout or oxidation of contacts
• The winding is damaged
• The armature with the spring wears out
• The hull is destroyed

It consists of a solid body, so if it breaks, it is impractical to repair it.

You can understand that replacement is required by the following signs:

• Bendix does not return when starting the engine, and a whirring sound can be heard under the hood
• When the starter is working, the power unit does not work
• When turning the ignition key, clicks are heard, but the element itself does not rotate.

Check and replacement

To check, just take a screwdriver and close its contacts, which are located on the back of the device. When the circuit is closed, the starter should work, but if it remains stationary and only a click is heard, then it should be replaced.

In order to replace the starter relay on a Chevrolet Niva, you need to do the following:

• Unscrew the three bolts that secure the part
• Removing the relay
• Installing a new part
• Checking the work

If everything is done correctly it should start

If you have an idea of ​​how everything works and you are sure that the cause of the malfunction is in the retractor, then you can safely proceed to replacement and repair. If there are any doubts, then you need to check it on a stand under load, since it happens that without load it works perfectly, but under load it stops working.

Connecting a starter with an ME17.9.71 EURO-5 controller

In this engine control system, power is supplied to the starter solenoid relay winding through the contacts of the additional relay (Fig. 1.10-01).

The controller turns on the starter relay when the ignition is turned on, if the “correct” password is received from the APS control unit, and turns it off after the engine starts (the engine speed has reached 500-1000 rpm depending on the coolant temperature) or after 7-20 seconds (depending on the coolant temperature) after the starter starts cranking.

The controller prohibits the activation of the additional starter relay when the engine is running.
