In detail: do-it-yourself starter repair Niva Chevrolet from a real master for the site my.housecope.com.
Before proceeding with Replacing the starter, I disconnected the battery. First, I removed all the underbody protection of the engine.
The starter is fastened with three bolts, after they are unscrewed, it can be pulled out from the bottom of the engine, only the rod will interfere with this. So I unscrewed it right away.
Now you can unscrew the starter. The bottom bolt is easily accessible from below. I unscrewed it with a small ratchet.
I unscrewed the other two bolts from above. This is what the starter looks like from above.
Here I have already used a spanner key. At the key, just the collar part is slightly bent, otherwise there would be no meanness to these bolts. The middle bolt is also more or less available.
The top bolt is the hardest of the three to reach. But in principle, the key was easily thrown on it, only the key stroke turned out to be very small and it took a long time to turn it.
When all three bolts were unscrewed, the starter easily moved out of its place.
But in order to get it out of there, the starter protection from heat interfered. These are such sheets of metal around it. From the side of the box, the starter rested against the protection with its protrusions, into which the bolts are screwed. At this point, I just folded back the protection with my hands. On the other hand, the protection at the bottom is fastened with a nut. I tried to unscrew it with a large ratchet. She didn't give in. Then I pressed a little harder and she kind of turned around. And when I looked, I saw that the nut did not even think to turn away, but I just rolled the eyelet to which it was attached. True, at the same time, the protection bent back and allowed the starter to be removed and the mount itself did not break off at all and seemed to hold on tightly and did not rattle. I then left it all like that.

(It turns out that I was wrong here. The nut should not have turned away, it is welded to the mount. And 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 fit the starter allow you to remove it without disconnecting them.
Only 2 wires fit to the starter. One small red one that's just plugged into the connector. We disconnect it calmly by pulling the connector. The second healthy one, screwed on with a nut, closed with a rubber nozzle, by unscrewing which I completely took out 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, on which three gears run. So it flew apart 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 off plastic fragments.
This photo report shows in detail how to make with your own hands starter replacement by car Chevrolete Niva. 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 breakdown 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 procedure for replacing a starter. He can do it himself. From tools you'll need:
- Ratchet wrench and heads for 10, 12;
- Phillips and flat screwdrivers;
- A penetrating lubricant like WD-40 may be needed;
Also we advise you to read with our video on starter malfunctions, the main possible causes.

The truth is somehow not very hard to believe that this happened only from the ingress of water into the starter. Most likely, the water aggravated the already begun process of cracking of the plastic from overheating, when even in winter I turned the starter a lot to start. I just do not understand why this part is plastic? After all, it should have a fairly large load.
As it turned out, they don't seem to sell spare parts for the starter. I had to buy a new one.
I installed it in the reverse order. First I connected the wires. Then he inserted it into place. I inserted the middle bolt first. At the same time, the bolt was inserted from above, with his left hand, and with his right hand he pushed the starter from the other side of the protection. Then he inserted the top bolt and tightened both of them. After that, I inserted and tightened the bottom bolt from below. After that, I screwed back the rod, which closed the starter outlet and the engine protection. And the starter protection was left in the bent position. I connected the battery and checked that everything works.
When everything was already collected, I was able to state that there is nothing super complicated in this operation.

It may happen that the Chevrolet Niva does not start, or it does, but with periodic interruptions. This may be due to a failure, for example, of the electrical or fuel system. The most common breakdown is when the starter fails. But in order to correctly and fully carry out the diagnosis, it is required to remove the starter, the Chevrolet Niva is no exception.
This device is a direct current electric motor, which comes into activity from a permanent magnet, which is combined with a planetary gearbox, plus a two-winding electromagnetic relay. Therefore, before dismantling, you should understand whether it is the reason that the engine does not want to start. This can be determined both visually and by replacing the battery.
It is necessary to do a number of actions:
- 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 a click of the retractor relay is heard, thereby there is not enough power to turn the crankshaft in the engine. This problem is eliminated by stripping the contacts of the starter, battery, various groups of contacts.
- 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.
To make a replacement you need:
- We disconnect the terminals from the battery, if this is not done, then a short circuit may occur, which will lead to a complete replacement of the wiring
- Using a ratchet wrench, remove the crankcase protection
- We tighten the three bolts that secure the starter
- We dismantle thermal protection
- Together with the wires, carefully pull out the unit, pulling it out, carefully pull the wires towards you and disconnect from the device.
- The power wires that are connected can be cleaned, perhaps the reason for the unstable start of the engine lies in poor contact.
After it has been removed, you can make diagnostics and subsequent repairs.
When the starter is removed, you can try to repair it yourself or take it to a specialized service. If you have experience and an idea of how everything works and you, for example, are sure that the cause of the breakdown, for example, lies in the failure of the retractor relay, then you can start repairing yourself. But in any case, to be sure that this is the problem in it, it should be checked on a special stand where there is a load, since at idle it can work as needed, but not under load.
Another reason for poor ignition can be a malfunction of the planetary gear, which has plastic parts. You can understand in what condition they are by unscrewing the unit and disassembling it in half, for this, simply unscrew a couple of nuts in its back.
As the masters say, the Chevrolet Niva starter, unsuitable for repair, since spare parts for it are not sold, but time does not stand still and you can do everything yourself. After the repairs are made, everything is assembled and installed in place in the reverse order.
Dismantling the starter on a Chevrolet Niva car is performed to replace the failed elements. To carry out repair work, prepare a standard set of tools and perform the following sequence of actions:
- After removing the starter, unscrew the nut and disconnect the wires of the positive brushes from the contact bolt.
- We unscrew the two screws and remove the traction relay from the starter. A gasket will be installed between the relay and the gear housing. Replace it if damaged.
- Raising the loop of the traction relay armature slightly upward so that it disengages from the lever, remove the anchor.
- Now we unscrew the two nuts of the tie rods holding the starter housing with the gearbox.
- We take out the bolts and remove the starter cover from the drive end assembly with the gearbox.
- Prying off with a flat screwdriver, remove the gearbox with a drive from the cover.
- Remove the rubber seal from the starter gear drive lever. If it is damaged, replace it with a new one.
- Next, we remove three planetary gears from the carrier axles. Wash them in kerosene and inspect them for mechanical damage or excessive wear, replace them with new ones if necessary.
- Remove and disassemble the starter drive.
- Now we need to remove the circlip from the internal gear.
- Then remove the washer and support from the shaft.
- Remove the internal gear from the shaft.
- Next, remove the central gear from the armature shaft. Rinse it and inspect for mechanical damage and temporary wear, if necessary, replace it with a new one.
- We take out two tie rods.
- Further along the perimeter, we pry the armature shaft support with a small flat screwdriver.
- We remove the armature shaft support and the washer, which will be installed right there on the armature shaft.
- We take out the armature complete with the brush holder from the starter housing.
- Bend back the brush spring holders using a small flat screwdriver.
This completes the repair work on disassembling the starter on the Chevrolet Niva car. Carry out the necessary repairs, then reassemble the starter in reverse order.
The resistance should be very large (strive to infinity). Otherwise, replace the brush holder with a new one.
In case of strong wear of the brushes, we change the brush holder assembly.
We assemble the starter in the reverse order. We mount the brush holder before installing the armature in the starter housing. Before installing the brush holder on the armature collector, slide the brushes into the guides and tie them with wire. After installing the brush holder on the armature collector.
We install the stop ring of the drive gear on the stop ring using sliding pliers.
We install the traction relay so that its control terminal is located on the right side.

Before that, I read books to imagine how to shoot it, read the forum. In general, nothing too complicated, only inconvenient access to it. When I already on the car looked where it is really located and how it all looks, I even doubted whether it was worth doing this. But then I decided to try it all the same.
In the end, I can say that it is not that difficult. Therefore, I decided to make a photo report, maybe someone will come in handy.
It is true that I did not photograph how I shot the old starter, I only filmed the process of installing the new one, but I will give these photos in reverse order to show how to remove the starter.
First, I removed all the underbody guards.
Now you can unscrew the starter. The bottom bolt is easily accessible from below. I unscrewed it with a small ratchet.
I unscrewed the other two bolts from above. This is what the starter looks like from above
Here I have already used a spanner wrench. At the key, just the collar part is slightly bent, otherwise there would be no meanness to these bolts. The middle bolt is also more or less available.
The top bolt is the hardest of the three to reach. But in principle, the key was easily thrown on it, only the key stroke turned out to be very small and it took a long time to turn it.
When all three bolts were unscrewed, the starter easily moved out of its place.
On the other hand, the protection at the bottom is fastened with a nut. I tried to unscrew it with a large ratchet. She didn't give in. Then I pressed a little harder and she kind of turned around. And when I looked, I saw that the nut did not even think to turn away, but I just rolled the eyelet to which it was attached. True, at the same time, the protection bent back and allowed you to remove the starter and the mount itself did not break off at all and seemed to hold on tightly and did not rattle. I then left it all like that.
(It turns out here I was wrong.The nut did not have to turn away, it is welded to the mount. And you need to unscrew the bolt that goes into this nut on the other side.)

Only 2 wires fit to the starter. One small red one, which is simply plugged into the connector. We calmly disconnect it by pulling the plug. The second healthy one, screwed on with a nut, closed with a rubber nozzle, by unscrewing which I completely took out the starter.

Like breast augmentation: here's the boob before. here in the process, but after!
One good punch in the ear replaces three hours of educational conversation.
food, rustling and swearing softly ..
Now it is clear why the starter needed an additional heat shield - in order to protect the entot plastic crown of teeth from heating and destruction.
Propeller, at the bottom attachment point of the screen, you need to unscrew not the nut, but the bolt. The nut is welded to the ear
