Reverse gear does not engage on a Niva Chevrolet, what should I do? — AutoCall

And maybe someone will sit down at TO1 to check it - and everything will work as it should, the law of meanness. It can be countered, because there is a counter washer there. At the moment the speed is turned on, they are lubricated, carried out by splashing oil in the box.

The fifth speed may disappear when turned on. Apparently it works, but not for everyone.

Remove the gear selection mechanism drive. Unscrew the two nuts securing the bracket to the support plate. Remove the bushing plate from the holes. It is advisable to block the differential on a slippery surface, for which you need to stop the car and drive about 1 m in the opposite direction or allow partial wheel slip.

So, let's look at the location of all the gears in the box and how they are engaged.

Below is a diagram that will make it easier to understand. So, as you can see, the scheme is standard, the first four speeds are the main ones and are turned on in turn.

Fill with oil to the level of the oil filler hole of 1.6 liters. The transmission oil change is complete. Replacing the Niva Chevrolet secondary shaft oil seal A constant decrease in the oil level in the Chevy Niva gearbox housing can be caused by a loss of tightness of the transmission secondary shaft seal. To replace the secondary shaft oil seal, you will need a 30 mm wrench, a screwdriver, a mandrel and a hammer.

To replace the secondary shaft oil seal, remove the transmission intermediate shaft. Remove the centering ring seal and unscrew the nut securing the elastic coupling flange. Remove the centering ring Remove the lock washer and flange Using a screwdriver, remove the oil seal from the rear cover of the gearbox, apply sealant to the new oil seal. Press the oil seal into the rear cover of the Chevy Niva gearbox through a suitable mandrel. Install all removed parts and the intermediate shaft in the reverse order of removal.

Check the gearbox oil level and add if necessary. Removing and installing the Niva Chevrolet gearbox The main faults that require removing the gearbox from the car are: I drove to an open field.

When is repair required?

Without a flashlight, but to an advantage with a key of 13, tighten the clamp. About 20 times I managed to adjust it so that all gears were engaged like clockwork!

The main mistake was not the first one, which I did not take into account: Before loosening the clamp, you need to catch the neutral with the lever, and then loosen it - adjust and tighten it! Pour, pour, pour, pour S It’s better to tilt the car a little to the right so that more can fit in. I always do this. There, they say, 5th gear is high and at the standard level there is just enough oil to work. But, you can do it more often.

And again about changing oils. So, after changing the oil in these units, the likelihood of their breakdown increases sharply.

From practice it has been observed that there is practically no need to change the oil in the gearbox and differentials throughout the entire service life.

It is necessary to monitor the level and its condition, but change it only in case of strong leaks and, naturally, when the oil level becomes below normal. Under no circumstances should you add oil if you do not know exactly all the parameters of the oil, only change it, otherwise oils of different bases and additives may conflate.

If water gets into the oil, since flooding is not uncommon in our country, in this case it is necessary to replace it. Very often, unjustified oil changes in these units cause maximum trouble and inconvenience.

This is due to wear of the secondary shaft oil seal.

Through the gaps formed between it and the shaft, oil flows out of the box. A decrease in lubrication level is fraught with increased wear and negatively affects the gear shift mechanism. Gearbox of this car To avoid unnecessary expenses, you need to replace a worn oil seal in a Chevrolet Niva.

This is a difficult but necessary operation. To carry it out you need: Remove the transmission flush shaft, remove the centering ring seal and unscrew the elastic coupling flange nut. The oil seal is now visible between the gearbox rear cover housing and the shaft. Sitting behind the wheel of a Niva Chevrolet SUV, the driver sees not one lever under the dashboard, but two.

So, as you can see, the scheme is standard, the first four speeds are the main ones and are turned on in turn. To engage fifth speed, move the lever to the extreme right position and press forward.

To engage the rear, you must still press the lever down in the neutral position, then move it in the same way to the right position and press it back.

When to use a differential lock

The Chevrolet Niva has high cross-country ability in all types of off-road and mountainous terrain. Many of them can be easily overcome with a locked differential. This driving mode is recommended:

on roads with reduced cross-country ability;
on steep ascents and descents;
when moving on dry (loose) sandy surfaces;
when driving on ice, deep snow or crust.

As a conclusion, the story “How to turn on all-wheel drive on a Chevrolet Niva: diagram and video instructions” is offered. By the way, it is recommended to lock the car at least once a week, especially in winter.

How to use a transfer case in a field, box design

The relatively complex scheme for distributing torque from the internal combustion engine to the wheels is explained by the universal purpose of the Niva 2121 - if used correctly, it can be used comfortably in the city and along muddy country roads.

Such properties are ensured by the presence of a transfer case with a center differential lock, complementing a 4- or 5-speed manual transmission, depending on the year of manufacture.

The lever, located closer to the dashboard , is responsible for turning off/on the center differential, the second “small” lever controls the range multiplier and has 3 positions: high and low rows, as well as neutral.

Design and principle of operation of the Niva 2121 transfer case

The transfer case mechanism includes more than 60 independent parts, which is confirmed by the presented drawing. Therefore, it is quite prudent to name the main elements and their purpose.

A pair of gears are tightly seated on the drive shaft, one of them (large) is intended for high gear, the second (small) is responsible for low gear. They have serrations with straight and oblique profiles. The first ones are in contact with the coupling, the second ones - with the intermediate shaft. The inclusion of one or another row causes the coupling to move along the hub in the horizontal direction, after which it is connected to the gear on the transfer case drive shaft.

Transfer case location and functions

Location of the transfer case in the Niva 21213

The transfer case occupies an intermediate position in the vehicle transmission between the gearbox and the driveshaft. It has its own body in which its components are located.

The transfer case helps to implement such SUV capabilities as:

Center differential lock.
Disabling the drive axle.
Increased torque of the drive wheels.
Distribution of torque along the wheel axles.

Reverse gear on a Chevrolet Niva does not engage, what should I do? - Behind the wheel

As stated in the regulations, it should be changed every forty-five thousand kilometers, and before that, it is advisable to warm up the car or drive it so that it does not become completely cold and is sufficiently liquid. To make the change you need the following set of tools:

Why is the Jimny such a special car?

A good car, the price of which will clearly exceed $000 in the USA. His name is Suzuki Jimny. Its attack angle is 34º and its exit angle is 31º. It impresses with a much larger ventral angle of at least 46 degrees, which has no problem negotiating huge slopes or moving between rocks. You mentioned that your front and rear axles are rigid?

Aesthetically, it is a correct car with an almost exotic touch and a design that has not gone out of style. However, not everything is pink: as we mentioned earlier, this is a very small car, it has four seats and its 113 liters of luggage is a joke.

Despite everything, it is worth remembering its very competitive price. This is the ideal car that turns into a high-caliber SUV, or one that is specified for fleets.

The rest of the trim adds convenience, but you'll never be able to equip air conditioning, cruise control or satnav.

Any unnecessary container to drain waste

The main stages of replacing fluid on a Chevrolet Niva:

We substitute a prepared special container under the place where there is a special hole through which waste is drained from the gearbox housing itself.
To drain easily, remove the plug from the holes that are responsible for filling and draining the oil, and drain it.
After the oil has been drained, the drain plug must be cleaned of various contaminants and inserted into place.
If the oil that you drained contains a lot of contaminants or contains a lot of impurities, then the gearbox is washed, after which about nine liters of special flushing oil is poured into the crankcase itself, and the plug is screwed back into the oil filling hole.
We hang up all the rear wheels or one, engage first gear and start the engine, it should run for about three minutes.
After the engine has been running, drain the flushing oil, wipe the oil drain plug and install it in place.
Using a special device or a regular syringe, pour new oil into the crankcase. Fill in 1.6 liters. After the entire procedure is completed, we put the plug in place.

At this point, the process of replacing the fluid in the box can be considered complete.

Of course, there is no option for an automatic transmission or other motorization. Engineers modernized the old platform and added a number of standard features and a new brand identity: wide split railings. Despite the controversy, the styling continued its success, with the public captivated by the generous interior space, elevated driving position and 327-litre boot.

A high ground level works well in urban groves without compromising stability. But he wants to finish, high level of noise on the road and parts such as pedals, air leaks that let water into the cabin, trunk that can only be opened with the key and any injection and ignition locks.

How to replace the secondary shaft oil seal

If the secondary shaft of the gearbox has a leaky seal, this can lead to a decrease in the oil level. In order to carry out replacement repairs, you need:

Reverse gear is difficult to engage

Despite its specs, it's a great buy because it's hard to find a model this spacious, a little wrapped, and equipped at this price point.

In addition to convenient space for people and luggage, you can display the autopilot on the road, talk about the consumption indicated on the on-board computer, or even lean on the station to change a flashing light that has stopped working after the control panel has warned you. All this in a car that was born cheap.

Completely original headlight: 464. Original brake disc: 491. Original rear view mirror: 170. Original brake pads: 179.

The most revealing is the intermediate expression, which already has hydraulic steering, rear windshield wiper and hot air as standard equipment.

Engine mounts An easy problem to solve, usually confused by clutch wear: when the mounts rupture, they cause cramps in the cranks. A simple visual analysis will already identify the problem.

And so to replace we go through the following steps:

Removing the intermediate transmission shaft
Remove the seal from the centering ring, unscrew the nut that secures the flexible coupling flange, then remove the centering ring
Remove the flange and lock washer
seal and apply sealant
The final step is to press the oil seal into the gearbox using a suitable mandrel. We install all the parts that were removed in the reverse order. We check what level the oil is at; if we see that it is not enough, then we need to top it up.

Removing gearboxes on Niva Chevrolet

What are the main faults when it is necessary to remove the gearbox:

Exhaust tip Ensure that it is present and does not show signs of visible corrosion: there are cases where it falls off and causes a concentration of hot gases in the barrel floor, aggravated by the lack of thermal insulation in place. In extreme cases, it can even melt the liner.

Ignition Symptoms of a system malfunction include a flashing panel fault indicator and minor engine failure. The scanner almost always indicates a defect in the coil, which costs about 500 reais in an authorized one.

And the space is great even for tall people. I don't like the finish: it's very plasticky and noisy, especially in the trunk lid and glove box, which doesn't close properly. Consumption could be better.

It's difficult to change gears
Various noises appear
The gears switch on themselves or, on the contrary, switching off is difficult
Oil is leaking

Its removal is also required when replacing the clutch.

To remove the gearbox:

Place the car on a pit or a special lift
Disconnect the terminals from the battery, remove the protection
Drain the oil from the box
The front driveshaft and intermediate shaft should be removed
Disconnect the wires from the reversing lights
We remove the cover of the handle with which we change gears
Unscrew the handle and remove it with the cover together
We unscrew the nut that secures the support plate of the PP mechanism and remove the rear power support unit
We unscrew the nut and the clamp that tightens the mechanisms that change gears
Remove the MPP drive by unscrewing three bolts
Unscrew the bolts that secure the clutch housing shield
We remove it from the hose by unscrewing the two bolts of the clutch cylinder
Removing the lateral stability stabilizer
We remove the entire mechanism assembly, namely the clutch housing and gearbox

Thus, having completed all the points, you can change the oil or the entire gearbox on a Chevrolet Niva yourself, the process is not entirely automatic, so you will have to work hard.

Experts note that during the operation of a Chevrolet Niva, something happens that it stops engaging in reverse gear. This happens due to the fact that the car has a worn-out rocker, which plays an important role when changing gears.

It should be noted that in the Niva Chevrolet there are two such scenes: one is for changing gears, and the second is for switching the transfer case.

The design of the rocker and its purpose on the Niva Chevrolet

Backstage location.

In technical language, the word “link” means the gearbox drive rod. This is a complex mechanism and is designed to connect the gearshift lever in the cabin and the rod of the gearbox itself. In the interior of the Niva Chevrolet there is a backstage located near the gearshift lever, and therefore it is quite easy to find it.

Reverse gear is difficult to engage

On modern domestic SUVs, which is the Chevrolet Niva, the rocker life is quite large. It has to be changed on average after 100,000 kilometers. But the resource can be greater. It all depends on the accuracy of the driver and the operating conditions of the vehicle.

If the rocker fails, the driver will notice the following:

It is impossible to engage first or reverse gear.
The fifth speed may disappear when turned on.
Reverse gear is engaged if the driver wants to engage one of the front ones.

The presence of such moments indicates that the backstage is out of order. It is recommended not to rush to remove the gearbox itself and carry out repairs. This may simply require adjustment of the rocker itself. Despite the fact that such a task is quite troublesome, it is less expensive than repairing or replacing the entire gearbox.

Adjustment steps:

After such actions, the work of adjusting the scenes can be considered completed. All that remains is to test it in action. When such measures do not bring the required result, the product will need to be removed and repaired.

Reverse gear slips out

If, after adjusting the rocker, the driver observes other malfunctions, for example:

problem with engaging reverse gear,
lever stroke increased,
reverse gear goes out,
speeds turn on noisy and tight,

then the backstage will need to be replaced.

instructions: adjusting the rocker on a Chevrolet Niva

And a few words about the transfer case rocker The transfer case rocker performs similar functions to a boxed product, only the speed mode shift lever is not used as often as the transmission. From this it follows that the transfer case rod has a much longer service life.

Changing the oil in the transfer case

The 2121 transfer case, of course, requires regular maintenance. The main maintenance work for transfer case 2121 includes changing the oil according to the automaker's recommendations. It is recommended to change the oil every 45 thousand kilometers. To perform this procedure, you need to take a twelfth hexagon, a syringe for filling the oil, the oil itself and a container for processing. It is best to change the oil in an inspection pit or on a lift.

The order of work is as follows:

We unscrew the drain plug above the waste oil container and wait until it all drains;
Screw in the drain and unscrew the filler plug;
Fill with oil using a syringe until it reaches the bottom edge of the filler hole;
Screw the plug.

Do not forget that only transmission oil should be used, and it has different characteristics compared to conventional engine oil.

Reverse gear does not engage on a Niva Chevrolet, what should I do?

Difficulty engaging or “crash” of a engaged gear is one of the problems faced by Chevrolet Niva owners. This can make driving very difficult and even make it impossible to use the car.

Such difficulties do not always indicate a faulty gearbox. In some cases, it is possible to restore normal operation of the gearbox without expensive complex repairs to the unit.
