Author: Ivan Baranov

In any vehicle, the gearbox is one of the main units that determine the quality of the car's ride. Accordingly, the occurrence of breakdowns in the operation of power units will, one way or another, affect the driving of the car, especially when it comes to the gearbox control lever. Today you will learn how the Niva Chevrolet rocker is changed and adjusted and how to choose a new component for your car.

Next, the guide rod is removed from the shaft. If there is a large play in the hinges of the detected link that cannot be adjusted or the hole for the axle is too worn, then the mechanism is removed and replaced with a new one.

To turn it on, you can start the engine and move the gearbox lever until the car starts moving. Afterwards, the engine is turned off, the first gear remains on, and shoes are placed under the wheels. Don't forget the handbrake. Replacement is made if there is play in the hinges or severe wear of the hole for the gearshift handle axis.

Also, if there is damage to the boot, it must be replaced with a new one. To do this, cut off the old boot and remove it, and install a new one in its place, having previously lubricated the internal parts with Litol.

Disassembly and assembly of the gear selection mechanism

In all other situations, the backstage can be repaired. To do this, you will need to purchase a special repair kit, which includes plastic seals. Before installing the seals, they will need to be lubricated with Litol. This completes the repair of the product; all that remains is to assemble all the parts in the reverse order of removal.

Once assembly is complete, don't forget about the new clamp that had to be cut when removing the cover.

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. Remove the lower guide plate washer.

Taking out one guide bar with two springs. Remove the guide plate from the lower end of the lever.

Remove the upper guide plate washer. Using a screwdriver or tweezers, remove the rubber sealing rings of the bolts from the grooves in the body. Removing the gearbox linkage Also: The linkage has a turnbuckle and a protective cover that must be removed. But be careful not to destroy the fasteners. The cover must be unscrewed in the opposite direction, and then the fastening clamp must be cut.

If the secondary so-called gearbox shaft has a broken 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.

All original headlight: 464. Original brake disc: 491. Original rear view mirror: 170. Brake pads Original: 179. The most revealing is the intermediate expression, which already has hydraulic steering, rear 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.

Next, remove the cover from the lever. The front of the floor tunnel lining is removed.

The latch is unfastened from the lever and the axle is removed. The shift lever is removed by holding it upward. The remaining rubber cuff must be returned inside the removed lever. The bolts securing the lever housing are removed and the rocker is removed.

You will need to remove the rubber bushing rod from the shaft. An old element of the transmission system that has exhausted its service life. If the speeds start to turn on very slowly or the speed that should turn on is not turned on, you can try to adjust the mechanism.

Of course, this is only relevant if the condition of the drive can be visually assessed as working. If the connecting elements of the mechanism's hinges operate with a large amount of play, then it would be more advisable to replace the component. How to choose a new backstage? What kind of rocker should I put on a Niva Chevrolet?

Before driving your vehicle, make sure that the transmission control lever moves from neutral to all six gears.

The shift lever is removed by holding it up.

If the screwdriver does not fit into the locking hole, the position of the rod is not adjusted correctly.

At the point in the engine compartment where the selector rod passes through the bulkhead, loosen the selector rod pinch bolt A near the rubber coupling B to allow free play between the two halves of the selector rod.

Move the gearbox control lever so that the tip of the screwdriver is inserted into the locking hole in the lever housing; Make sure that the lever is still in the fourth speed position. In the engine compartment, tighten the pinch bolt on the gear selector rod to the required torque.

Remove the screwdriver from the locking hole and install the plastic plug. Fifth speed disappears when it is turned on; 3. Reverse gear is engaged when the forward five gears are selected.

This indicates a malfunction of the drive rod, but you should not rush to remove the gearbox and repair it, as you can try to adjust the product. Although adjustment is a rather difficult task, it is easier and cheaper than replacing a box or a link. Location of the rocker clamp bolt Adjusting the rocker includes the following steps: First gear is engaged at the gearbox.

To turn it on, you can start the engine and move the gearbox lever until the car starts moving. Afterwards, the engine is turned off, the first gear remains on, and shoes are placed under the wheels.

Don't forget the handbrake. Lower into the overpass and loosen the bolt of the rocker clamp.

Inside the car we find a plastic traction lock and move it to the extreme left position until it stops. After this, you should go down into the pit again, but tighten the loosened clamp bolt. At this point, the gearbox thrust adjustment is completed, and you can check its performance. If you want to avoid unexpected unpleasant surprises while driving, then the condition of the scenes should be at the appropriate level. On most cars, this element is a fairly reliable mechanism that can easily last up to a thousand years.

In what case is replacement performed?

The gearbox is simpler than the engine, but sometimes it needs replacement. Often wear and damage force the car owner to buy expensive spare parts. Ultimately, the sum equals a used box in good condition. In this case it is better to change. Thus, a used box will be the best option.

In addition, replacement may be required after severe impacts and destruction of both the gearbox housing and internal mechanisms, which “dragged” along the parts of the fastenings to the housing. The price of a new Niva box is not high. Thus, repairs will cost the car owner less than many analogues.

Chevrolet Niva gear shift lever dangling

Backstage of the Niva Chevrolet jeep

Continuing our study of the Russian Niva Chevrolet jeep, which is a relative of the VAZ family of cars, we will pay attention to such a detail as the rocker. What is it anyway and where is it located? Surely, every driver today has often heard during training at a driving school about how the instructor “swears” at the obsolete stage when he changes gear. Yes, indeed, the rocker is a part of the box that performs an important function, but in the Chevrolet Niva there are two such devices: one rocker is used to change gears, and the other is used to switch transfer case modes. But this is actually what this material will say.

Purpose and design of the gearbox gate

The rocker is technically called a box drive rod and is an all-encompassing mechanism designed to connect the box shift lever with the box rod.

On Chevrolet Niva jeeps, the rocker is located in the cabin near the lever itself, as in almost all models of Russian cars. Finding it is not difficult if you know what a gearbox is. The slide is located near the transmission shift lever and has the appearance shown in the photo below.

Photo of the backstage located in the vehicle interior

On older models of vehicles from the Russian automobile industry, the location of the rocker was located under the bottom of the car, but this reduced, first of all, the service life of the product, which affected efficiency.

Rocker assembly for VAZ 2123 gearbox control mechanism

Dear customers, in order to avoid errors when sending the VAZ 2123 gearbox control mechanism, please indicate your car model and year of manufacture in the “Comment” line.

The gearbox is designed to change the torque developed by the engine in order to obtain different traction forces on the drive wheels when starting the car, accelerating, moving and overcoming road obstacles; changes in vehicle speed and direction; the possibility of driving the car at low speeds, which cannot be provided by the engine, and disconnecting the engine from the transmission for a long time when parked or when the car is moving by inertia (coasting).

The VAZ-2123 transmission is made on the principle of permanent (non-disconnectable) all-wheel drive with a lockable center differential.

The general layout of the VAZ 2123 transmission completely repeats the 21213 transmission layout: clutch, gearbox, intermediate shaft, transfer case, two cardan shafts to the front and rear axles, a split front axle and a continuous rear axle. The differences are hidden within each unit.

The gearbox (Gearbox) has undergone almost no changes inside, only the rear bearing of the input shaft and the intermediate bearing of the secondary shaft have been replaced with more durable closed-type bearings. The same five-speed three-shaft design, with constant mesh gears and synchronizers in all gears. Gear ratios are also preserved: 1st gear - 3.667; 2nd gear - 2.1; 3rd gear - 1.361; 4th gear - 1.0; 5th gear - 0.819; reverse gear - 3.526.

Attention: Only the gearbox control drive has been significantly changed. In the place where the Niva's gear shift lever is located, an extension with a horizontal rod 250 mm long is installed, on two linear bearings. The extension rod is connected to the gear shift lever through a spring-loaded ball joint. This made it possible to bring the lever closer to the driver and make gear shifting much more convenient.

1 – support plate fastening nut; 2 – gearbox control drive rod; 3 – hatch cover gasket; 4 – gear shift lever hatch cover; 5 – gear shift lever handle; 6 – gear shift lever; 7 – gear shift lever cover; 8 – sealing cover; 9 – screw for securing the hatch cover; 10 – rear support; 11 – gear shift lever housing; 12 – lower housing of the gear shift lever; 13 – nuts for fastening the rear support; 14 – rear support washer; 15 – nut; 16 – spacer ring; 17 – retaining ring; 18 – ball joint housing; 19 – gear shift lever spring; 20 – ball joint slider; 21 – nuts securing the ball joint housing; 22 – protective cover; 23 – rod end; 24 – support plate; 25 – gearbox.

The clutch uses a new pressure plate from the VAZ-2112. The driven disk has been preserved from the Niva, but somewhat modernized - it does not have a thrust flange, since the clutch design is backlash-free, like on front-wheel drive VAZ cars. In connection with this, the clutch engagement clutch has also changed. The introduction of a backlash-free clutch made it possible to reduce the force on the clutch pedal by several kilograms and eliminate another maintenance operation - adjusting the free play.

Transmission repair is necessary for the following symptoms: noise when shifting gears, difficult shifting on and off, spontaneous shifting of gears, transmission oil leakage.

In some cases, you can get by just adding oil. If the signs of malfunction have not disappeared, it is necessary to proceed to repairing the gearbox. The first option is to contact a service station. Repairing a VAZ gearbox is quite possible in your own garage.

Design and principle of operation

The Chevrolet Niva transmission includes the following components:

A five-speed manual gearbox allows you to change not only the amount of torque, but also the direction of rotation.
Split front axle with a gearbox mounted on the power elements of the body.
Dry single-plate clutch, which, when the pedal is pressed, briefly disconnects the transmission from the engine.
Solid rear axle, into which the gearbox and differential are integrated. This allows you to increase and distribute torque between the wheels of the same axle.
The intermediate shaft through which torque is transmitted from the gearbox to the transfer case.
Transfer case that distributes rotational energy between axles.
Two cardan shafts transmitting power to the axles (front and rear).
Constant velocity joints that drive the steering wheels.

It works like this: engine torque is transmitted to the manual transmission through the clutch, then through the intermediate shaft to the transfer case and a pair of drive axles.

We get rid of vibration and extraneous sounds of the Niva transfer case forever

The characteristic howl and hum of the transfer case on VAZ-21213 cars, alas, is familiar to many owners of such cars. Let’s figure out what is the reason for these problems, and most importantly, how to get rid of them without using “collective farm” methods, such as additional noise reduction.

Understanding the terminology

Let's start by diving into the materiel. Transfer case (TC) is a separate unit of an all-wheel drive vehicle, which provides multi-mode power distribution from the engine to the front and rear axles.

Chevrolet Niva gearbox design

Chevrolet Niva is the successful result of fruitful cooperation between Russian and American engineers. The car is ideal for use in Russian conditions. He is not afraid of bad roads or sudden changes in temperature. The Chevrolet Niva has a spacious, roomy interior and a powerful 1.7- or 1.8-liter engine with distributed fuel injection. The Chevrolet Niva all-wheel drive car can be used as a representative city or country car for trips into nature. High quality workmanship and low cost have made this comfortable car a sales leader in Russia.

A new passenger five-seater SUV, replacing the popular VAZ all-terrain vehicle. The conceptual solutions he inherited from the Niva - a monocoque body, permanent drive of all wheels - are combined with a number of innovations. Adjusting the Chevrolet Niva backstage Among them is a five-door body with glued glass; a trunk door that opens to the side; engine with distributed fuel injection; electric power steering, powerful heater.

The chassis and transmission of the old Niva have remained virtually unchanged structurally - modernized, life-tested units have been used. Here is a list of modifications to the Chevrolet Niva: the front axle gearbox is “decoupled” from the engine; The design of the gearbox drive has been changed; extended intermediate shaft; the transfer case has fine-meshing gears; front and rear driveshafts are unified.

Perhaps the only modification that still won its right to life. Although with significant changes and with the participation of a foreign company. Although initially everything looked quite tempting. And here's what happened at first...

The base model of the new Chevrolet Niva family is a car with a five-door station wagon and a 1.7-liter gasoline engine equipped with an electronically controlled distributed fuel injection system.

Main design features: the engine is located longitudinally in the front of the machine; permanent all-wheel drive with center differential lock; five-speed manual transmission; two-speed transfer case; electric power steering; fifteen-inch wheels shod with 205/75R15 tires. Adjusting the Chevrolet Niva rocker In addition to the base engine, there are three more. Two of them are gasoline engines of the VAZ-21231 and VAZ-21233 models. Well, the third is a real surprise from VAZ - the domestic turbocharged diesel VAZ-3431. Moreover, for truck versions of vehicles, the diesel engine was supposed to become the base one.

Make sure that nothing prevents you from grabbing the handbrake handle at any time, you never know. But boxes of juice, tape cassettes, the hem of your companion’s lovely dress can get in your way.

How to Remove the Rocker on a Chevrolet Niva

Niva Chevrolet Jeep Wings

Continuing our study of the Russian Chevrolet Niva, a relative of the VAZ family of cars, we will look at details such as the wings. What is it anyway and where is it located? Of course, every driver today heard, when he was studying at a driving school, how the instructor “swears” behind the scenes when he changes gears. Yes, this is behind the scenes part of the Gearbox, this is an important function, but the Chevrolet Niva has two such devices, one of which is used to change gears and the other to change gears. But this stuff will really tell you that.

Gearbox side designation and design

A technical linkage is technically called a box rod and is a complex mechanism designed to connect a stock transmission gear lever

On Chevrolet jeeps, the Niva bar is located in the cabin next to the lever, as on almost all models of Russian cars. Not hard to find if you know what a box is. The scenes are located near the gear lever and look like the photo below.

Photo of the backstage located in the salon

On older models of the Russian auto industry, the placement behind the scenes was at the bottom of the car, but at first this shortened the life of the product, which affected efficiency.

Adjustments behind the scenes

The fenders on Chevrolet Niva jeeps have a long service life of more than 100 thousand kilometers. But this resource depends, firstly, on the integrity of driving, since from time to time drivers may notice transmission failures, for example:

When you try to engage first gear, it shifts into last;
5th speed is lost when turned on;
Reverse speed decreases when selecting 5 forward gears.

This indicates a faulty drive rod, but do not rush to remove the transmission and repair it as you may be attempting to adjust the product. Although adjustment is difficult, it is easier and less expensive to change the drawer or slides.

Clamp Bolt Placement

The settings behind the scenes are as follows:

First gear is cut off at the checkpoint. To activate it, you can start the engine and move the gear lever until the car goes away. When the engine is turned off, first gear remains engaged and the shoes are placed under the wheels. Don't forget the handbrake.
To come down in the summer and loosen the clamp bolt.
In the cabin we find a plastic traction lock and move it to the last left position until it stops.
Then go back down into the hole, but tighten the loose clamp bolt.

Next, remove the cover from the lever. The front of the floor tunnel lining is removed.

Transmission linkage: removal

The rocker on a Niva Chevrolet SUV is removed in the following order:

Open the hood of the car and find the clutch tip of the lever, as well as the gearbox linkage. The rod has a turnbuckle with a protective cover that will need to be removed.
In the Shnivy interior, remove the trim of the gearbox lever using a screwdriver. You should be careful not to damage the latches.
Turn the cover the other way, and then cut the fastening clamp. Next you need to remove the cover from the lever.
Remove the front of the floor tunnel lining.
Unfasten the fasteners from the lever and remove the axle.
Remove the shift lever by moving it up, and the remaining rubber cuff must be returned inside the removed lever.
Remove the lever housing fixing bolts and remove the rocker.
Remove the rod (rubber sleeve) from the shaft.
Observe the rod for damage or defects. This way it will be possible to determine whether the backstage requires repair or replacement.

Transmission of Chevrolet Niva and Lada 4x4: what is the difference

The first thing that catches the eye of the average user is that the Lada’s transmission is controlled by two levers, while the Chevrolet Niva has only one, not counting the gearbox control lever. This is due to the fact that Chevrolet’s upshift and downshift ranges, as well as the center differential lock, are implemented using a single-lever design. In addition, the Niva's front axle gearbox is not attached directly to the engine cylinder block, and the transfer case has three mounting points, unlike the Lada, which has two.

Nevertheless, both cars are absolutely identical in transmission design, have one engine for two, but due to the transfer case set back, the Niva’s intermediate shaft is longer than that of the Lada 4x4 by exactly 250 mm. Moreover, both cardan shafts driving the front and rear axles are completely interchangeable.

How to remove engine and transmission protection?

The standard equipment of the Chevrolet Niva includes protection in the form of a curved steel plate. This part prevents damage to the engine crankcase and the most critical elements of the transmission. Below it is a mudguard that prevents road dirt from entering the engine compartment.

However, the protection prevents maintenance of the gearbox and front axle gearbox. Therefore, to change the oil or repair key transmission elements, the plate must be removed. To do this, you will need 8 and 10 socket wrenches.

Removing the protection and mudguard is not difficult:

Unscrew the four mounting bolts.
Remove engine and transmission protection.
Unscrew the five self-tapping mounting screws.
Remove the mudguard.

Installation of parts is carried out in the reverse order of removal.

How to adjust the rocker on a Chevrolet Niva

The gearbox linkage is a part of a multi-lever unit that acts as a connecting link between the gearbox lever and the rod. Note that in the Chevrolet Niva, such an element as the rocker is located at the bottom of the car body near the driveshaft. This component is susceptible to the appearance of moisture and contamination, and this, after some time, deteriorates the quality of lubrication of rotating parts. Consequently, the components wear out, causing various problems.

In relation to other components of the transmission, the rocker, also known as the gearbox control drive rod, is considered a relatively simple device in structure

However, for correct operation, the condition of the scenes should be given due attention

That is, it is important to do repairs or adjust traction on the Chevrolet Niva in due time. Any car owner wants no force majeure to occur during the movement, and therefore the condition of the scenes must be monitored

Any car owner wants no force majeure to occur during the movement, and therefore the condition of the scenes must be monitored.

On most vehicles, the rocker looks like a fairly durable device that is quite capable of being used for about a hundred kilometers without replacement. At the same time, drivers are not insured against damage to this unit. How can you identify the need to repair the rocker on your Chevrolet Niva? This can be determined for the following reasons:

The gearbox lever clearance has increased significantly;
there are problems with gear shifting (the lever may float);
Reverse gear does not engage;
adjusting the backstage became impossible.

If the gears work poorly or the wrong one works at all, it makes sense to adjust the mechanism. Naturally, such a fact is relevant only when the position of the drive is visually assessed as working. When the connecting parts of the device’s hinges operate with significant play, then it is advisable to replace the component on the Chevrolet Niva.

When studying a Chevrolet SUV, which we know as a relative of the VAZ, many do not understand what a rocker is and where to look for it. By the way, in Chevrolet there are 2 such devices. One rocker is designed to change gears, while the other switches transfer case modes.

Consequently, sometimes car owners notice malfunctions in the operation of the gearbox, manifested in the following:

when engaging 1st gear there is a spontaneous shift to reverse;
when switching on, 5th speed disappears;
activating reverse gear instead of selecting forward 5 gears.

The reasons mentioned indicate damage to the drive rod, but there is no need to remove the gearbox and repair it as soon as possible. First, you should try to adjust this element. And although setting up the unit is not an entirely simple task, it is cheaper and easier than changing the entire box or slide.

Backstage repair

How to properly adjust the driver's seat
The gearshift linkage is an element of a multi-lever assembly, which is designed to connect the gearbox lever and the rod that fits the power unit. In Niva Chevrolet cars, the rocker is located under the bottom of the vehicle, next to the cardan. This component is susceptible to contamination and the formation of moisture on it, which over time can deteriorate the quality of lubrication of rubbing parts. As a result, parts begin to wear out, which can subsequently lead to various problems.

Chevrolet Niva car - 2013 model

As stated above, the rocker is an integral part of the transmission system in Niva Chevrolet cars. Compared to other components of the transmission system, the rocker, which is also called the gearbox control rod, is a relatively simple mechanism in its structure

However, for correct operation, the condition of the scenes should also be given special attention.

In particular, we are talking about timely repair and adjustment of drive traction. If you want to avoid unexpected unpleasant surprises while driving, then the condition of the scenes should be at the appropriate level.

Installation of the backstage from "Kalina"

Replacing the VAZ 2110 gearbox

On a VAZ 2110 you can successfully install a slide from Kalina:

To do this, it needs to be modified a little.
The cardan from the new model is 20 mm longer than the original “tenth”.
Therefore, it needs to be cut, to do this, use a lathe.

Note: when cutting manually, you can ruin the part, since when the temperature of the metal increases, it loses its strength.

The replacement of the slide must be carried out in the garage from the inspection hole.
Remove the plastic tunnel from the car interior.
Also remove the boot.
Remove the old rocker, unscrew all the fasteners from under the bottom of the car.
Install a new link and adjust it.

Note: adjustment must be carried out in order to later avoid troubles that arise during operation of the vehicle.

Why is it recommended to install a cardan from the new Kalina? On VAZ-2110 models, universal joints made of less resistant material are installed, so they quickly fail. This causes premature play in the rocker, which usually affects the quality of gear shifting while the vehicle is moving. After purchasing a new link, a visual comparison should be made of the old cardan and the purchased one. The comparison will be entirely in favor of the new acquisition. The Kalina cardan is made of better quality material, it is much more wear-resistant.

Gearbox slides for VAZ 2110

Do-it-yourself gear shift assembly adjustment

To correctly adjust the gear selection mechanism you will need a 13 key

Sequencing:

We start the engine, engage 1st gear. As soon as the car starts to move, we stop and turn off the engine. In this case, we leave the first gearbox speed in the ON position. We put the car on the handbrake and anti-rollbacks.
We loosen the coupling bolt of the clamp securing the connecting rod of the gearbox under the body. For ease of work, you can use a lift, overpass, pit or jacks.
We move the plastic traction lock located in the passenger compartment all the way to the extreme left position.
Then we fix the loosened bolt of the mounting clamp back.

You can also try one more method to eliminate rattling and play in the gearbox handle: using a “13” wrench, you need to tighten the lever fastening nut until the axial play is eliminated.

Why is downshift needed?

It is difficult to imagine a transfer case without the main functional component - a reduction gearbox. Positioning the lever in the rear direction reduces the transfer case value to 1.2.

You can often encounter the following type of misconception: switching the rear handle can increase the power characteristics of the motor. But this is not true. It serves to change the gear ratio between the engine and the wheels. By increasing it, the traction forces on the wheels will increase. There is also a reduction gear in the dispensing mechanism.

DON'T SPEND MONEY ON REPAINTING! Now you can remove any scratch from the body of your car in just 5 seconds.

Its operation can be controlled using the rear handle. When we shift the lever back, we will have a gear ratio of 2.135 - this is a low gear. It is recommended to downshift such a gear only when the car is stationary and the clutch is depressed. Despite the fact that the manual does not contain such a restriction, novice and inexperienced Niva drivers are not recommended to switch while driving, since the Niva transfer mechanism is not equipped with a synchronizer.

Diagram of a 5-speed gear shift mechanism for VAZ-2123

At the factory, modern Niva cars are equipped with a five-speed gearbox, made according to the three-shaft type.

Gearbox design:

Heat removal from heated rubbing parts is realized by manufacturing a multi-fin structure on the surface of the crankcase and also to protect the speed selection unit from overheating and exceeding excess pressure, a breather is present in the design.

The tightness of body connections is ensured through the use of pressed shaped gaskets. In case of repair of the gear selector assembly, it is also possible to use a liquid gasket former. The lower part of the gearbox housing is covered with a stamped steel protection with a gasket.

In a modern design, the gearbox housing and synchronizer clutches are reliable and adapted to operating conditions on Russian roads.

The factory crankcase protection on the Chevrolet Niva copes with its function quite well. For safe travel on rural roads and off-road, you can consider installing additional combined protection for the gearbox and transfer case. There are many different options and designs offered on the Internet, where you can choose the option you like, both in price and in terms of configuration and quality of metal.

Over time, any mechanism wears out, sooner or later it will be necessary to carry out maintenance and adjust the gear mechanism. There are quite a lot of companies on the spare parts market that produce any components, parts and related materials for both old and new Chevrolet modifications.

Interesting! According to reviews from the owners of these cars, you can carry out maintenance and repair of the gear shift mechanism on a Chevrolet with your own hands at home.

Location of control and drainage holes:

a control hole is made for ease of oil change in the upper left part of the crankcase housing;
the technological hole for draining used oil remains unchanged at the bottom of the frame.

It is equipped with a screw-on magnetic plug to collect small metal shavings. Lubrication of rubbing surfaces is carried out by spraying. Domestic oil seals are installed in the housing at the output of the primary and secondary shafts. The axis of the gearbox speed gear is fixed on the rear cover of the gearbox housing.

The rotation of the input shaft is carried out through 2 ball bearings. For the industrial shaft, the design of the unit includes double-row ball roller bearings.

A breather is installed in the upper part of the housing (near the clutch). If the breather malfunctions (cap failure), transmission oil may be squeezed out through the seals and housing connections.

The arrangement of the shaft gears is implemented in the following sequence:

toothed gear of constant mesh with the input shaft;
III;
I.

Advice! The manual transmission of the VAZ 2123 is quite “gentle”; overloads should not be allowed; it is recommended to change the oil without waiting for a mileage of 45-50 thousand km.

Purpose and design of the gearbox gate

The rocker is technically called a box drive rod and is an all-encompassing mechanism designed to connect the box shift lever with the box rod.

On Chevrolet Niva jeeps, the rocker is located in the cabin near the lever itself, as in almost all models of Russian cars. It’s not difficult to find it if you know what a box is. The rocker is located near the gearbox shift lever and has the appearance shown in the photo below.

On older vehicle models of the Russian automobile industry, the location of the rocker was located under the bottom of the car, but this initially reduced the service life of the product, which affected efficiency.

Backstage adjustment

The slide on Chevrolet Niva jeeps has a long service life, equal to more than 100 thousand km. But this resource depends, first of all, on the integrity of driving, therefore from time to time drivers may notice malfunctions in the operation of the gearbox, such as:

When you try to engage first gear, it switches to reverse;
5th speed is lost when it is turned on;
Reverse gear is engaged when selecting front 5 gears.

This indicates a malfunction of the drive rod, but do not rush to remove the gearbox and repair it, because you can try to adjust the product. Although adjustment is a rather complicated task, it is easier and cheaper if you change the box or the link.

Placement of the rocker clamp bolt

Adjusting the backstage includes the following steps:

The gearbox is engaged in 1st gear. To turn it on, you can start the engine and move the gearbox lever until the car starts moving. Afterwards, the engine is turned off, gear 1 remains on, and boots are placed under the wheels. Don't forget the handbrake.
Lower into the overpass and loosen the bolt of the rocker clamp.
Inside the car we find a plastic traction lock and move it to the last left position until it stops.
After which you should go down into the pit again, but tighten the loosened clamp bolt.

Removing the gearbox from a Chevrolet Niva

Removal and installation of the box and minor repairs.

At this point, the gearbox thrust adjustment is completed, and you can check its performance. If the adjustment does not help, then it will be necessary to remove and repair the product.

Mechanism malfunctions

If, after the procedure for regulating the traction of the transmission of a Chevrolet Niva car, subsequent malfunctions are identified, which appear in the form of:

the free play of the gearbox lever increases;
difficulty changing gears;
speeds are turned on tightly;
Engaging in the wrong gear or inability to switch gears.

If such problems are identified, there is a need for more severe repair work or replacement of the scenes. But to be able to carry out such actions, the device must be removed.

Removing the gearbox linkage

You can remove the slide in the following order:

Having opened the hood of the Chevrolet Niva, you need to find the connection between the tip of the lever and the gear shift rod. The rod has a turnbuckle and a protective cover that must be removed.
In the interior of a Chevrolet Niva car, the gearshift lever trim is removed using a screwdriver. But be careful not to destroy the fasteners.
The cover must be unscrewed in the opposite direction, and then the fastening clamp must be cut. Next, remove the cover from the lever.
The front of the floor tunnel lining is removed.
The latch is unfastened from the lever and the axle is removed.
The shift lever is removed by holding it upward. The remaining rubber cuff must be returned inside the removed lever.
The bolts securing the lever housing are removed and the rocker is removed.
You will need to remove the rubber bushing (rod) from the shaft.
Next, you need to inspect the rod for flaws in order to find what will be needed: repair or replacement of the product.

Replacement is done if there is free play in the hinges or severe wear of the hole for the gear shift knob axis. Also, if there is damage to the boot, it needs to be replaced with a new one. To do this, cut off the old boot and remove it, and install a new one in its place, having previously lubricated the internal parts with Litol.

In all other situations, the backstage can be repaired. To do this, you will need to purchase a special repair kit, which contains plastic seals. Before installing the seals, you will need to lubricate them with Litol 24. This completes the repair of the product; all that remains is to assemble all the parts in the reverse order of removal. Once assembly is complete, don’t forget about the brand new clamp that had to be cut when removing the cover.

How to remove and replace?
