Auto & Chevrolet Niva & Chevrolet Niva backstage adjustment

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.

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.

Malfunctions

The most common causes of malfunction:

the backlash and vibration of the gearshift lever has increased;
5th speed goes out or reverse gear is engaged;
It is difficult to engage reverse;
fuzzy long-term switching of speeds.

Reference! Vibration of the gearshift lever is the most common problem that occurs in many vehicles when the internal combustion engine is running in the range of 2500 - 3500 rpm.

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.

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.

Important! The permissible clearances of the drive unit must correspond to the following values in millimeters: D = 1.5±0.5; E = 1±0.5.

The lever nut must be tightened to a torque of 24.5 Nm (2.5 kgfm).

If, after the adjustment has been made, the same difficulties with gear shifting and vibration remain, this means that this unit is worn beyond the permissible norm and needs to be replaced.

Rear and front gear ratios of Chevy Niva

Gear values for Chevrolet Niva manual transmission from 2002 to present:

I – 3.67;
II – 2.10;
III – 1.36;
IV – 1.00;
V – 0.82;
ZX transmission – 3.53.

To engage the gearbox, you need to move the gearshift lever all the way to the right and push it down with a little force, pressing the gearshift knob in the direction of the rear seats of the car.

The VAZ-2123 gearbox does not have a separate synchronizer for the reverse gear. Accidental engagement of reverse gear is eliminated due to the use of a curved locking stop in the form of a bracket in the design.

Important! The reverse speed of the Niva Chevrolet gearbox, like any car, must be turned on when the car is completely stopped.

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.

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.

Chevrolet Niva gearbox lever play

It worked the first time. A month or two passes, and it’s already April. I can’t turn on the rear one. Come on, off into the wilderness, shouting “not Russian words,” I put chains on all the wheels.

We managed to switch on some gear, and, accordingly, it was liquefied.

We move the lock to the extreme position on the right. Then tighten the loose bots securing the scenes from the pit.

After such actions, the work of adjusting the scenes can be considered completed. Use a screwdriver to push the rubber-plastic guide sleeve inside the lever housing and slide it along the shaft.

Remove the four bolts securing the lever housing to the body base. Remove the housing and remove the shaft from it. Using a wrench, you unscrew several screws holding the gear shift lever housing to the car body.

Repair and replacement of the rocker on a Chevrolet NIVA

After dismantling the housing, the gearbox shaft is removed from it. 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. 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.

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.

Node device

On older models, this unit is located under the bottom of the car, thereby being exposed to increased contamination and moisture.

The design of the gear shift mechanism does not have complex connections, the work is carried out without much load, but owners often encounter wear and tear on this unit.

Backstage of the Niva Chevrolet SUV

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.

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.
