Repair do-it-yourself hand-outs niva chevrolet

In detail: do-it-yourself repair of a Chevrolet Niva handout from a real master for the site my.housecope.com.

We unscrew the second nut, keeping the shafts from turning with a mounting blade inserted between the bolts.

Remove the nut and washer. Remove the drive shaft flange.

. press the front bearing.

Remove the rear bearing in the same way.

We put marks on the front and rear differential housings so as not to disturb the balance of the unit during assembly.

We remove the rear bearing of the intermediate shaft in the same way as the front bearing of the drive shaft.

To check the technical condition of the transfer case parts, we thoroughly clean and rinse them with kerosene or white spirit.

There should be no cracks on the crankcases and box covers, and wear or damage (chips, dents, etc.) should not be allowed on the surfaces of the bearing bores. Damage to the crankcase and cover mating surfaces can cause shaft misalignment and oil leakage. Minor damage

we fix it with a file; in case of significant damage and wear, we replace the parts with new ones.

Damage is not allowed on the working surfaces, threaded part and shaft splines. There should be no scoring or wear marks on the seating surfaces of the gears. Chipping or excessive wear of the gear teeth is not allowed. Ball and roller bearings should be free from damage on treadmills, cages, rollers or balls, as well as cracks or chips on rings. Radial bearing clearances should not exceed 0.05 mm. The rotation of the bearing rings must be smooth, without jamming. We replace damaged bearings with new ones.

Deformation of forks and sticking of rods in openings of crankcases are not allowed.

Video (click to play).

We check the absence of traces of jamming on the gearshift clutch hub, as well as on the splines of the differential housing. We clean burrs and scuffs with a file. In case of crushing or destruction of the ends of the clutch teeth, replace the clutch.

We check the condition of the surface of the pinion axle and the holes in the differential housing; in case of minor damage we grind the surface with fine-grained emery paper. We check the condition of the surfaces of the gear journals of the axle drives and their bore holes in the differential cases, as well as the condition of the surfaces of the gear washers and the end surfaces mating with them on the cases and gears of the axle drives.

Before assembling the transfer case, we clean the mating surfaces of the crankcases and covers from the remnants of old gaskets and sealant. We assemble the transfer case in reverse order.

When assembling the center differential, we combine the marks on its housings.

We install the spring washer on the axis of the satellites from the side of the blind hole at the end of the axis.

We press on with pipe sections or tool heads of a suitable size.

.and differential bearings.

In the same way we press on the bearing of the rear axle drive shaft, the rear bearing of the intermediate shaft, the front and rear bearings of the drive shaft. We install the drive and intermediate shafts in the transfer case at the same time.

Apply a thin layer of silicone sealant to all gaskets.

After tightening the nuts of the rear bearings of the drive and intermediate shafts to the prescribed torque (see Appendices, p. 346), we lock the nuts by pressing their collars into the grooves of the shanks of the shafts.

After assembly, fill in oil (see "Changing the oil in the transfer case" p. 32).

Greetings, dear friends! In today's article we will talk about repair, transfer case and gearbox on Niva Chevrolet. On the car, which we will carry out repairs, there were complaints from the owner about the presence of extraneous sounds in the car while driving.Increased vibration, hum, noise, and during the check it was revealed that the vibrations come from the transfer case of the car, the hum comes from the bearing of the input shaft in the gearbox. In general, now I will tell you how to fix these problems yourself.

We disassemble the transfer case for Chevrolet Niva change bearings and eliminate vibration - step by step instructions.

After we have replaced the bearing, we begin to assemble the transfer case. The assembly is carried out in the reverse order, but an important point: it is necessary to clean all adjacent surfaces from the old sealant and apply a new one to them .

Not complete disassembly of the gearbox on the Chevrolet Niva; we change the bearings and eliminate vibration - step by step instructions.

Now we proceed to incomplete disassembly of the gearbox on the Chevrolet Niva. In our case, only the bell needs to be removed. It rests on 5 nuts, so we unscrew them.

We immediately draw attention to the fact that the oil seal ran here, therefore, it is necessary to replace it.

Here is a photo of the input shaft bearing. Remove the stoppers from the outer and inner sides of the bearing race.

The bearing itself is difficult to remove here, so you cannot do without an assistant. Of course, you can get by with a puller here, but we did not have a suitable puller at hand. Therefore, we did it as follows:

One held it with montages on both sides, as if pulling it out
I knocked out the bearing by tapping through the copper lining on the input shaft.

In general, we collect everything and put it back in place in the reverse order. Well, that's how it is. There are still questions! Write them in the comments, if possible I will answer them.

Cars of the Niva family differ from VAZ cars by permanent all-wheel drive - they have two driving axles. In total, the transmission of the VAZ SUV has three differentials - one for each axle and another center differential.

The transfer case "Niva" is designed to distribute traction forces between the axles, and works on the principle of a 2-speed gearbox.

The distribution box is not present in all VAZ cars, but only on cars with two drive axles. In the transmission, the transfer case (RK) is installed at the rear of the gearbox; the rear propeller shaft is attached to its shank, which connects the transfer case to the rear axle. The front axle is also driven by the RK, it is connected to the transfer case by the front propeller shaft.

The reduction gear in the RK is designed to obtain high torque, it is used to overcome difficult road sections, helps to cope with off-road conditions. The VAZ Niva transfer case contains the following main parts:

the body itself;
front axle drive shaft;
intermediate shaft;
drive shaft;
gears;
bearings;
differential housing;
satellites;
differential lock clutch;
gear shift clutch;
flanges (for connection with cardan shafts);
oil seals;
control levers.

The VAZ-21213 model is an off-road passenger car with permanent all-wheel drive and differential lock. Brand 21213 is a restyled version of the first VAZ SUV VAZ-2121. RK Niva 21213 has three gears:

the first - with a gear ratio of 1.2;
the second, reduced - with a number of 2.135;
neutral.

21213 is equipped with 4-speed and 5-speed gearboxes, and when the first speed of the transfer case is on, the car works in standard mode, the gear ratios in the transmission are from 5-speed. The checkpoints are as follows:

When you turn on the second position of the transfer case lever (reverse position), the gear ratios change (decrease):

On normal roads, the first gear is constantly engaged on the transfer case, the transfer case control lever (reduction gear) is pushed forward. The neutral transmission of the RK disconnects the transmission, and in this position the car does not drive, there is also neutral in the checkpoint.

Often motorists ask the question - why do we need a neutral gear in the transfer case. Neutral is used when connecting additional units to the transmission, for example, a mechanical winch, in which case a power take-off must also be installed.

On Niva cars (with the exception of Chevrolet Niva), two main types of transfer cases are used:

21213 (modifications 21213-1800020-01 and 21213-1800020-02):
21214 (modifications 21214-1800020-01, 21214-1800020-02, 21214-1800020-10).

Between themselves, the transfer case has almost the same design - on the RK 21214 there is additionally a speed sensor drive.

The distributor of the VAZ 2123 car basically has the same device as the node 21213/21214, but the Chevy Niva has:

different control mechanism (with one lever);
an additional support is installed (on a simple Niva, the RK is mounted on two supports, on a VAZ 2123 car - on three supports).

The distribution box on the Niva is a fairly reliable unit, repair problems in the mechanism itself arise mainly due to the insufficient oil level in the RK - if for some reason the oil has leaked out, intensive wear of all parts occurs. Among the frequently occurring malfunctions are:

vibration on the body at different speeds when driving a car;
vibration at the moment of starting a car from a place;
noise in the transfer case when the car is slipping or entering a turn;
tight inclusion of a higher or lower gear, difficult engagement of the lock.

Vibration in the body is the main "disease" of the Niva, it often arises from the wrong centering of the transfer case. Most often, vibration occurs on VAZ 21213/21214 cars, since the RK is mounted only on two supports on the sides of the body, on the Chevrolet Niva the transfer case is already installed on three supports. But before you start adjusting the position of the transfer case, you should check the condition of other parts of the chassis - vibration may also occur for other reasons:

cardan shafts are poorly fixed;
wheels are not balanced;
there is a backlash in the driveshaft crosspieces (especially the backlash in the rear driveshaft crosspieces affects vibration);
vibration comes from the engine itself.

Vibration when starting off on the Niva can also occur for the following reasons:

the fastening of the installation supports of the distributor was unrolled;
the rubber on the RK supports themselves broke.

Correct installation of the transfer case can be done in several ways. Most often, in auto repair shops, repairmen use the following method:

hang the car on a lift;
weaken the fastening of the hand-out;
start the engine;
turn on the transmission and accelerate the car according to the speedometer to the speed at which vibration occurs (it often occurs at speeds from 40 to 80 km / h);
without applying the brakes, they extinguish the speed with the engine, then turn off the ignition.

The distributor itself is centered in places, it remains only to tighten the fasteners of the supports.

You can also adjust the position of the RK using a wire, we do it as follows:

we loosen all four fasteners of the razdatka supports;
we fix one end of the wire to the rubber coupling of the propeller shaft;
we also attach a piece of wire to the CV joint, bring the other ends of the wire to each other;
we rotate the shaft, if the distributor is not centered, the ends of the wire will diverge during rotation;
the task is to install the transfer case using the selection method so that the ends of the wire practically do not diverge from each other in any position when turning the shaft.

The installation of the third support of the RK on VAZ 21213/21214 cars allows to reduce the level of vibration of the transfer case, with this support it is easier to center the transfer case. The part can be purchased at auto dealerships or you can make it yourself. The finished product comes with three long studs (for model 2121); to install the third support on this machine, you will need to unscrew the short studs from the transfer case and install new studs from the kit.We make repairs as follows:

dismantle the front passenger seat in the cabin;
remove the lining of the floor tunnel;
in the cabin, move aside the carpet covering the body amplifier (in front of the handbrake lever);
we remove the transfer case (as an option, you can simply hang it out, but with the removal of the installation of the third support it is more convenient to do it);
we attach a new support bracket to the RK body;
install the transfer case in place, center it in the optimal position, attach the side supports;
we combine the third support with the body, we drill two holes in the bottom;
using washers, bolts and nuts (included in the kit), we attach the support to the bottom of the body.

Vibration is more effectively eliminated by installing a stretcher under the dispenser. You can also make such a device yourself or buy a finished product at a car shop.

In order to install the subframe, the transfer case must be removed. It is more convenient to carry out such work in a pit, we carry out repairs as follows:

we leave the car in neutral;
we disconnect the propeller shaft from the distributor, it is advisable to mark the flange of the propeller shaft and the PK so that during installation, install the propeller shaft according to the marks - this way, the appearance of unnecessary vibrations is excluded;
dismantle the muffler mounting bracket;
remove the traverse of the checkpoint;
jack up the distributor, remove the side mounts of the RK;
we process the landing sites of the stretcher to the body with Movil;
we put the stretcher on the gearbox studs;
mark the attachment points of the subframe on the side members, drill holes, bait the bolts on the body;
we tighten all fasteners, except for the razdatka supports themselves;
we make the alignment of the RK;
finally tighten the transfer case supports.

It should be noted that the installation of an additional support or subframe on the RK does not always lead to the desired effect, in some cases the vibration only increases.

To repair the transfer case on a VAZ 21213 (21214) car, the assembly must first be removed. Removal is performed in the following order:

in the cabin we dismantle the plastic trim for the gearbox and gearbox levers;
we turn off the knobs of the transfer case shift levers, remove the casing under them;
we disconnect the speedometer cable, for RK 21214 it will be necessary to disconnect an additional speed sensor;
we unfold the bolts with nuts securing the elastic coupling of the front and rear propeller shafts, in order to remove the bolts, the propeller shafts must be turned - they are removed one at a time in one specific shaft position;
we install a jack (or other stop) under the distributor, mark the places where the side supports of the RK were attached. This is done in order to minimize the centering of the transfer case during installation;
we unscrew 4 nuts securing the RK to the gearbox;
unscrew 4 fasteners of the RK supports to the car body;
now all that remains is to dismantle the transfer case.

In order to change the amount of torque and distribute it between the rear and front axles, the Chevrolet Niva has a transfer case, which has two gears. These two axles are connected to each other by an interaxle differential, which divides the torque equally, and in order to increase the cross-country ability, the differential is locked, while the drive shafts are rigidly connected to each other.

Therefore, it is very important to know what a Chevrolet Niva handout device is, which it is also desirable for the owner of this SUV to know.

This device is fixed on several brackets to the floor of the car body. The parts in the box are made of aluminum alloy, which are interconnected with nuts and studs.
The upper part of the crankcase is equipped with a special hatch, which is closed by a steel cover. There are cardboard spacers in the space between the crankcase and the lid.
All shafts in it are sealed with cuffs, which are made of rubber-metal material. Also, rubber rings sealed such elements as: Differential lock, shift fork rod, speed sensor, as well as drive shaft
A drive shaft is mounted on a pair of ball bearings, and the outer rings are located in the crankcase and in the slots of the front cover.

If you read the regulations, it is recommended to change the oil in the transfer case every forty-five thousand kilometers. The following tools are required for replacement:

Key for twelve
Syringe
Capacity where you can drain the mining

After the tool is ready, we proceed to the replacement:

We unscrew the oil drain plug and drain the working off
We twist the drain plug back, and unscrew the filler
Fill with a syringe with new oil to the desired level, at this point the process can be considered complete.

Sometimes it is necessary to replace the transfer case on a Chevrolet Niva car, and in order to do this, it must be dismantled, for this it is necessary to do the following:

We take two keys for thirteen and seventeen, and disconnect the driveshafts from it
Disconnect from the transfer case from the passenger compartment, cover with handle
We remove the cover of the lever, which is responsible for switching the drive
For the existing box suspension, loosen the fasteners
Disconnect all wires from the lamp responsible for the differential lock
We install a support under the box, unscrew all the nuts that secure the pillow, and remove the distributor

In order for it to fall into place, you should do all the steps in the reverse order.

The transfer case works very noisy, every owner of the Niva probably encounters this problem, this noise is transmitted to the salon through the levers it contains. There are two ways to get rid of this howling.

You can buy special silent levers for a Niva handout, from which they are suitable, and will cost around 3,000 rubles.
You can make it yourself, while spending much less.

In order to make them yourself, you can take:

Lever repair kit from GAZ 31105 from a five-speed gearbox
Two levers from VAZ
Standard lever

With the help of a grinder, you need to cut off all the elements to the desired level, and then use a welding machine to weld it all.In time, it takes about two hours. The essence of this device is that due to rubber and plastic bushings, which are located on the lever of the box, noise and vibration are damped. Let's consider the whole principle with an example:

Removing the lever
We cut to the size we need, as in the pictures
The lever that changes gears is cut one centimeter above the narrowing
Saw the lever from the GAS below the thickening by one and a half centimeters
We put the resulting elements we need together.
Then we weld the native lever and the lever from the GAS together
On the welded part that turned out, we put on the existing part from the KP
We weld the upper part of the existing native lever as needed
We get the design we need
We prime and paint the resulting elements
We cut the upper part of the sealing gum, low and high gear

If everything is done correctly, they are almost indistinguishable from gratifying. As a result of the actions taken, we get that the inclusion is softer than it was, vibration practically disappears, strong noise disappears, and most importantly, you can do this yourself while saving money.

Transfer case overhaul - general informationOverhaul of the transfer case is a difficult procedure to perform on your own. It involves the disassembly and correct reassembly of many small assemblies and components. It is necessary to accurately measure the many gaps and correct them correctly by choosing the appropriate size shims and circlip. Thus, if it becomes necessary to overhaul the transfer case, its removal and installation can be performed by an amateur mechanic, while the actual repair and restoration should be left to the car service specialists. There is a possibility of purchasing remanufactured boxes - consult the specialists of the dealer department. In any case, the time and money spent on repairing and restoring the old box will turn out to be quite commensurate with the cost of purchasing a restored unit.Nevertheless, it should be said that the overhaul of the transfer case by the forces of even an inexperienced amateur mechanic is quite possible, provided that there is an appropriate special tool and an accurate and careful approach to performing each of the procedures, when not one of even the smallest steps is skipped.Tools required to perform a transfer case overhaul include pliers for removing and installing both inner and outer circlips, bearing puller, sliding hammer, drift set, plunger-type dial indicator, and possibly a hydraulic press. In addition, a strong, comfortable-height workbench equipped with a vice, or a stand for dismantling transmissions, is absolutely essential.When disassembling the transfer case, pay close attention to how each of the smallest components are installed, their position in relation to other parts, and the type of fasteners (take notes as you disassemble). The accompanying illustrations provided here are intended to help you understand the layout of the box - however, drawing up explanatory notes during disassembly still much more reliably guarantees the correctness of subsequent assembly.
