Replacing the transfer case boot of a Chevy Niva

Adjusting the backstage of the Niva Chevrolet

Continuing our study of the Russian SUV Chevrolet Niva, which is a relative of the VAZ family of cars, we will pay attention to such a detail as the rocker. What is it and where is it located? Probably, every current driver often heard while studying at a driving school about how the instructor “swears” at the obsolete stage when he changes gear. Yes, indeed, the rocker is a gearbox part that performs an important function, but the Chevrolet Niva has two such devices - one rocker is used to change gears, and the other is used to switch transfer case modes. But this is what this material will actually tell you about.

Purpose and design of the gearbox gate

The rocker is technically referred to as a gearbox drive rod and is a complex mechanism designed to connect the transmission shift lever with the gearbox rod.

On Chevrolet Niva SUVs, the rocker is located in the cabin near the lever itself, as in many 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.

Backstage adjustment

The link on Chevrolet Niva SUVs has a long service life, equal to over 100 thousand kilometers. But this resource depends, first of all, on the integrity of driving, so sometimes drivers may notice failures in the operation of the gearbox, such as:

When you try to engage first gear, it switches to reverse;
Fifth speed disappears when it is turned on;
Reverse gear is engaged when 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 backstage includes the following steps:

The gearbox engages first 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, 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 the adjustment does not help, then the product will need to be removed and repaired.

Mechanism malfunctions

If, after the procedure for regulating the traction of the gearbox of a Niva Chevrolet, further malfunctions are identified, which manifest themselves in the form of:

the free play of the transmission lever increases;
problems with gear shifting;
speeds turn on slowly;
Engaging in the wrong gear or being unable to switch gears.

If such problems are identified, the need for more serious work arises - repair or replacement of the backstage. 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 sequence:

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 need to be removed.
In the interior of a Chevrolet Niva car, the gearshift lever trim is removed using a screwdriver. But be careful not to damage the fasteners.
The cover must be turned 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 up. 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 defects to determine what is required: repair or replacement of the product.

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.

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 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 new clamp that had to be cut when removing the cover.

And a few words about the transfer case rocker

The transfer case performs similar functions to a boxed product, only the gear 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. If similar problems are noticed as in the gearbox, then it is worth replacing the transfer case, since its mechanism does not allow repair or replacement.

Based on all that has been said, the gearbox and transfer case are important elements of the Chevrolet Niva, without which it is impossible to engage gears.

How to choose a new backstage?

What kind of rocker should I put on a Niva Chevrolet? This question came to the mind of every Niva car owner who had to deal with a malfunction of this element. In fact, there is nothing difficult in choosing a component.

In practice, many car owners of the above car models install mechanisms from classic Fiat cars on their vehicles. According to reviews on the Internet, these devices are completely suitable for installation in a Chevrolet Niva. However, there is also a negative side. In practice, Niva cars equipped with a mechanism from Fiat cars require more careful adjustment of the element. In addition, despite Italian quality, these components of the transmission system are more susceptible to wear and tear.

Therefore, when choosing a mechanism, you should not “be fooled” by the stories of handicraft “garage” craftsmen and come up with a new headache for yourself. For installation in a Chevrolet Niva, it is better to purchase a standard rocker, which is equipped with basic models of Niva cars.

Replacing an element

As a rule, the need to repair this component arises after installing or repairing the gear shift drive. If you have replaced the drive, but when driving you feel how the vibration of the gearbox lever remains, then, most likely, there is increased play in the lever hinge mechanism. This means that the hinges should be repaired, and accordingly, it may be necessary to replace the rocker.

If you decide to replace a component at home yourself, then prepare in advance everything that you may need during the work process. In particular, we are talking about:

wrenches on "12";
wrench set to “14”;
socket wrench at “10”;
clamp for securing the gearshift lever cover;
stationery knife;
Phillips screwdriver.

Of course, you will also need a new mechanism if you decide to replace it.

First of all, open the hood of your Chevrolet Niva and find the connection between the tip of the gearshift lever and the gear shift rod. Once you see this connection, take the appropriate wrench and loosen the nut of the mounting screw.
After this, remove the turnbuckle and its protective cover.
Now get into the car and remove the front part of the floor covering. Next, remove the gearshift lever boot frame. Be careful, you will need to remove it carefully to avoid damaging the clips.
Next, you will need to turn the shift lever boot inside out. Having done this, you will see the cover fastening clamp. Take pliers or a regular stationery knife and cut through this clamp. After this, the cover can be removed from the lever. Please note: the gearshift lever mounting clamp is disposable. That is, if you bite it with pliers or cut it with a knife, you will not be able to reinstall the part in its original place. Therefore, when assembling the parts, you will need to install a new clamp.
Next, you will need to remove the front portion of the floor tunnel lining. Depending on the year of manufacture of your Chevrolet Niva, the instructions for dismantling the floor tunnel lining may differ. Therefore, we recommend that you use the instruction manual specific to your car.
Now look at the gearshift lever. You will see that the axle lock is attached to it: this element must be disconnected from the lever. Having done this, the lever axis can be dismantled, simultaneously removing this axis from the holes of the gear shift lever and the rocker.
When the axle is removed, you need to remove the gearshift lever. To do this, you will need to pull the lever itself up. Then take a screwdriver and push the plastic bushing inside the gear lever housing. You need to move this element along the shaft.
Now, using a wrench, you need to unscrew several screws securing the gearshift lever housing to the car body. By unscrewing and dismantling the bolts, you can remove the housing and remove the gearbox shaft from it.
Next, remove the guide rod from the shaft.
Now you will see your backstage. If you see a large play in the hinges of the element that cannot be adjusted, or the hole for the lever axis is too worn, then you need to remove the mechanism and replace it with a new one. Since the process of replacing this element is not so easy, we recommend that you visually inspect all dismantled parts. If you have any doubts about their performance or reliability, it is better to replace them immediately.
After replacing the backstage, all parts must be assembled in the reverse order. Don't forget to install a new shift lever mounting clamp.

After installing the rocker, you will need to adjust the gearbox shift drive.

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.

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.

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.
