Niva 21214 DIY repair and maintenance

In detail: niva 21214 do-it-yourself repair and operation from a real master for the site my.housecope.com.

VAZ-2121 "Niva" is a four-seater off-road passenger car. Produced by the Volzhsky Automobile Plant.

The VAZ-2121 "Niva" car is a design development of JSC "AVTOVAZ". Produced since 1977. This is a vehicle for off-road driving, traveling to hard-to-reach places, hunting and fishing trips. The folding rear seat allows you to place and carry a variety of goods. The tailgate floor-level connector provides convenient loading and unloading.

"Niva" is a cross-country vehicle with a permanent non-disconnectable drive of all wheels with a center differential lock and a transfer case with a lowering row. The car had a very progressive design, combining excellent off-road qualities with the comfort of a passenger car, and had practically no analogues at that time. It has been successfully exported to many countries. The car became one of the first representatives of the now so popular "parquet" SUVs.

Body - all-metal, load-bearing, three-door, equipped with seat belts. Front seats - with head restraints, adjustable in length and backrest tilt, recline forward. The rear seat folds down to increase the luggage compartment. On request, the car is equipped with an electrically heated rear window, a cleaner and a rear window washer.

Another feature of this unique machine was the use of passenger car assemblies. So, its engine was created on the basis of 2106, the gearbox and rear axle are also borrowed from this car. Despite this, the "Niva" has a cross-country ability, unique for such a machine.

The car was equipped with a 4-speed gearbox with synchronizers in forward gears, or a 5-speed gearbox. The transfer case is a two-stage one with a center differential with forced locking. The cardan drive consists of an intermediate cardan shaft and cardan shafts for driving the front and rear axles.

The front suspension is independent, on transverse swinging arms, with coil springs, hydraulic shock absorbers and an anti-roll bar. The rear suspension is dependent, with coil springs, hydraulic shock absorbers, four longitudinal and one transverse rods.

Since the start of production, modifications have been produced with an in-line four-cylinder carbureted gasoline engine with a volume of 1.6 liters. The modification 21211, which appeared later with a 1.3 liter engine, was not successful.

As a result of the modernization of 1993, a new model "Taiga" was born, which was assigned the index "VAZ-21213". This is a four-seater off-road passenger car with permanent non-disconnectable all-wheel drive. It's hard to believe that there are 16 years between these modifications. During these years, the plant made almost no changes to the design of the 2121. And the changes made in the 21213 model are more cosmetic than technical.

Externally, the new car is distinguished by a modified rear part of the body. 21213 has a "long" third door to the bumper and new taillights. It has become much easier to load anything into the luggage compartment. The lock disappeared from the back door, which was constantly clogged with dirt. It can only be opened from the salon. True, the location of the handle that opens the trunk under the elbow of the rear left passenger is difficult to call successful: you have to act “by touch”. The bumpers are now painted light gray, which is more practical than the old unpainted aluminum.

The cabin has a new panel, new seats, new facings. The instrument panel is the same as that of the VAZ-21083 model.Only now the glare from it illuminates the windshield at night. The new seats are also made in the image and likeness of the "eight". They are more comfortable and more modern than the previous ones. But the mechanism, which folds the backrest for the passage of the rear passenger and moves the seat forward, is not reliable - after fifty operations it fails, due to distortions that have appeared, the back does not want to get into place. The rear plastic panels creak and squeak from light pressure. But now there is a pocket in the sidewall next to the left rear passenger.

The engine has been updated too. The working volume is increased to 1700 cm. A contactless ignition system and a Solex carburetor are used. An invisible but very significant improvement is the new shape of the combustion chamber. Modification of the engine along with changes in the transmission allowed to significantly reduce fuel consumption.

The transmission of the new car has a five-speed gearbox and main gears with a gear ratio of 3.9. Reinforced crosspieces are used. Their size changed and grease fittings appeared. In the transfer case drive - CV joint. Its purpose is to reduce vibration and transmission noise.

The brake system uses a vacuum booster and a master cylinder from the "eight". The effort on the pedals has decreased, but the wheel now lies “upside down” and nothing can be put into it. In addition, the procedure for adjusting the steering gear has become incredibly complicated - now you can only crawl up to it with a crooked screwdriver. The exhaust system contains new mufflers. Their bodies are not welded, but rolled, like those of the machines of the “eighth” family.

For the external market, a modification of the VAZ-21214 with central fuel injection was produced. In the "standard" version - VAZ-21214-00. This car is a design development of JSC "AVTOVAZ" with a permanent non-disconnectable drive of all wheels with a center differential lock and a transfer case with a lowering row.

The model range of JSC AVTOVAZ also included the temporarily produced transitional modification 21219 - a combination of the old body 2121 and the engine with transmission 21213. On request, the cars can be equipped with a 1.9-liter Peugeot diesel engine (VAZ-21215).
