Niva transfer case. Ways to eliminate vibration. How to center the transfer case on a Niva? Method for shorty and Chevrolet

Combines are indispensable when harvesting crops. With their help, the grain harvesting campaign occurs incomparably faster and with better quality. But the colossal loads experienced by such equipment lead to the need to constantly monitor its condition. Repair and modernization of the Niva SK 5m1 combine harvester requires professionalism. Experienced machine operators can do most of the work with their own hands. Thanks to the production of all components by the manufacturer of the combine itself, there is no need to look for an alternative to spare parts. Buy spare parts for NIVA SK 5. In case of modernization of the machine, parts from other combines are used. Particular attention is paid to the header, the chopping shaft of the threshing drum.

Transfer case location and functions

Location of the transfer case in the Niva 21213

The transfer case occupies an intermediate position in the vehicle transmission between the gearbox and the driveshaft. It has its own body in which its components are located.

The transfer case helps to implement such SUV capabilities as:

Center differential lock.
Disabling the drive axle.
Increased torque of the drive wheels.
Distribution of torque along the wheel axles.

Transfer case Niva 21213

Model VAZ-21213 is an all-terrain 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, lowered – with the number 2.135;
neutral

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

1 – 4,4;
2 – 2,52;
3 – 1,63;
4 – 1,2;
5 – 0,98.

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

1 – 7,83;
2 –4,48;
3 – 2,90;
4 – 2,14;
5 – 1,75.

On ordinary roads, the transfer case is always in first gear, the transfer case control lever (reduction gear) is pushed forward. The neutral gear of the RK disconnects the transmission, and in this position the car does not drive; there is also a neutral in the gearbox.

Motorists often ask the question: why is neutral gear needed in a transfer case? The neutral is used when connecting additional units to the transmission, for example, a mechanical winch; in this case, a power take-off must also be installed.

The device of the VAZ Niva transfer case

The transfer case is not present in all VAZ passenger cars, but only on cars with two drive axles. In the transmission, the transfer case (TC) is installed at the rear of the gearbox; a rear driveshaft is attached to its shank, which connects the transfer case to the rear axle. The front axle is also driven by the steering wheel; it is connected to the transfer case by a front driveshaft.

The reduction gear in the Republic of Kazakhstan is designed to obtain high torque, it is used to overcome difficult sections of the road, and 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 to cardan shafts);
oil seals;
control levers.

Combine harvester NIVA SK 5 - modernization, repair and maintenance

The NIVA combine harvester has a history of more than 40 years. Developed back in the Soviet Union, it still does an excellent job of harvesting grain. This model is well distributed throughout the country and is actively used in cleaning companies. This is due to the fact that the model does not have complicated mechanisms in operation and harvesting, and the spare parts are so reliable that they can last for decades.

The NIVA self-propelled combine is distinguished by its high productivity. Its grain harvesting speed is 5 kilograms per second. At a similar speed, many modern prototype combines harvest grain.

Today, more than 10 thousand models of this combine are in operation throughout the country.

Centering method

To carry out this work you will need a lift, although with some skill you can get by with simple supports. First you need to prepare the car. If there is a lift, it is raised up. If supports are used, the corners of the machine are jacked up one by one and it is placed on them. Please note that all supports must be stable, otherwise the work will be unsafe. You should also prepare the tool in advance. If there are no plans to simultaneously replace other parts, then it is quite possible to get by with a ratchet and a “13” head. During operation, an assistant must be in the cabin.

Adjustments are made in the following order:

To begin with, you should evaluate the condition of the splines on the cardans. If they are very worn, then most likely you will not be able to perform the alignment correctly. In case of significant wear, parts should be replaced;
The transfer case mount is inspected. Often the displacement can be seen with the naked eye;
Next, loosen the transfer case mount. Just don’t unscrew it completely;
After this, start the engine and “accelerate” the car to a speed of 80-90 km/h. In this case, the transfer case will fall into place on its own;
The crucial point is to consolidate the result obtained. This can be achieved in 2 ways. Mechanics argue which one is better, but both are used in everyday life. Most often, the engine is turned off, and with its help the transfer case and cardan shafts are stopped.
All that remains is to quickly tighten the nuts. Disadvantage here 2. Stopping the box in this way can have a negative impact on its condition.
Also, you need to tighten the fastener as quickly as possible, otherwise it will be of no use. A more reliable, but technically complex method is to tighten with the engine running;
The car is lowered to the ground and testing is performed.

If the vibration persists, the procedure should be repeated.

Combine harvester modernization

Main directions of modernization:

When installing more modern spare parts on the header, the efficiency of the entire system improves. The model is unpretentious in maintenance. Repair work is required after a long period of work or before the start of the season. In some cases, they resort to a significant increase in technical characteristics.
Modernization of the chassis consists of replacing the chassis variator with a volumetric hydraulic drive of the drive wheels. This increases the operating speed of the machine.
Installation of any parts with improved characteristics. Spare parts from more modern machines can be used.

The machine model is very unpretentious in maintenance. Repair of the Niva combine and its modernization can be done by yourself. Only experienced machine operators can perform such procedures. If faults are identified early, repairs improve the performance and longevity of the entire system. Machine operators always perform some work independently. Others require special equipment, workbenches and stands.

Eliminating prerequisites

The misalignment of the transfer case occurs due to an undeveloped design. Therefore, many craftsmen strive to modify the fastening so as not to bother with alignment once a year. A special frame is used for this. In recent years, it can be purchased in stores, but you can also make it yourself. The advantages of this modification are the following:

The transfer case is mounted on the rigid base of the subframe. The attachment to the body is made through a subframe, this allows to reduce the level of vibration transmitted to the body;
It plays the role of a kind of protection for the crankcase;
Also worth mentioning is adding additional rigidity to the side members.
Among the disadvantages, we can mention a slight decrease in clearance. Although, in light of the advantages, this does not play a special role.

To assemble the subframe you will need a square pipe. Some people use a corner, but in this case the structure will be less durable. The support plates are made of sheet steel. Before assembly, you should cut off the old transfer case mounting bolts. Now it will be installed on the subframe. The pipe is cut to size and the frame is welded. After that, holes are drilled in the crossbars for fastening the transfer case. It is important not to make a mistake with the sizes. The next step will be assembling the mount to the body. Sheet steel support plates are welded to the subframe. Holes are drilled in it. After fitting, you need to drill holes in the floor of the car.

M12 bolts should be used for fastening

, as well as thick washers.
After installing the subframe, do not forget to treat it with an anti-corrosion compound. This will increase the service life of the part. This is how, through simple manipulations, you can get rid of one of Niva’s sores. Conclusion
. Even great cars have flaws. The domestic SUV Niva is no exception. During active use, vibrations emanating from the transmission may occur. That’s when the question arises of how to center the transfer case on the Niva. In fact, this work is not difficult, but there are some nuances that are better to know before starting work. Some people, knowing this feature of this car, install a subframe, this can significantly reduce the noise of the transmission.

Repair and service

The model is quite unpretentious to maintenance. However, it may happen that due to long work, many parts will suffer a lot of wear and tear. Before the harvesting company, in order not to interrupt the harvesting process in the future, it is necessary to repair the Niva combine.

For a vehicle such as the Niva combine, repairs and modernization will be quite easy and without much difficulty. All components are still produced by the manufacturer. Repairing a Niva combine harvester with your own hands will not take much time. The main thing for this is to select all the spare parts necessary for replacement.

The moving elements of the reaping mechanism wear out the most. It is they who bear the entire main load during work. The SK 5 model is unpretentious in modernization. More modern parts can be installed on it to improve the operation of the entire system.

All hydraulic systems constantly require high-quality oil. It is also worth paying attention to the quality of connections of all nodes. Sealed connections prevent air from entering the system. Timely maintenance and repair of the Niva SK 5M1 combine harvester allows you to avoid breakdowns during harvesting campaigns, and also extend the service life of the entire system.

Niva transfer case. Ways to eliminate vibration

The Niva family of cars differs from VAZ passenger cars in permanent all-wheel drive - they have two drive axles. In total, the VAZ SUV has three differentials in its transmission - one for each axle and another center differential.

Header repair

Do-it-yourself repair of a Niva combine includes restoring the efficiency of the reaping mechanism. He is the most loaded. The Niva combine uses the ZHRN-6 header for a separate harvesting method. The purpose of the element is to mow and lay grain stalks. DIY reaper repair methods:

The main component of the part is a bevel gearbox. Violation of the clearance in its gears disrupts the operation of the system. To adjust the connection, different sized washers are used.
Restoring the conveyor belt. In case of rupture, the end is secured with an overlap. The overlap of the rest of the belt is from 100 mm. The cuff is cut off and a new one is installed. To secure the cuff at the ends, welding is carried out.
Do-it-yourself repair of the Niva combine harvester auger is possible without complex equipment.
Ball bearings are replaced by disassembling the driven shaft. The elements are pressed in using a puller. At the same time, the limiting ring and stuffing box are removed. The end of the pipe is flared.
Repair of the pick-up is carried out at the stand. A workbench and shelving are required. In the case of curved slopes or rakes, they are straightened.
Pipe journals are fused to provide a gap in the connection of up to 0.225 mm.

Frequent header malfunctions include breakage of the crank roller axle. If the gap exceeds 0.6 mm, the end of the roller is removed and knocked out of the crank. New elements are being installed.

The permissible deflection of the pick-up shaft is 1 mm. The support disks are installed with axial play of the rake arms within 1-1.5 mm. All rake fingers must be located in the water plane. If the rake touches the left side, the shaft retracts to the right. The movement is 2-3 mm. After this, the retaining ring and the coupling hub are attached. A half-hour run-in of the repaired pick-up is carried out.

Repairing a Niva combine reel involves straightening a bent pipe. It may be necessary to drill out the rivet to remove worn journal journal. Cracks appear at the attachment points of the pipe and disk. To eliminate this, the welds are renewed. You may need to replace a worn chain or sprocket teeth.

Eliminate vibration with additional fasteners

Installing the third support of the transfer case on VAZ 21213/21214 vehicles allows you 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 stores or made 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 housing and install new studs from the kit. We carry out repairs as follows:

dismantle the front passenger seat in the cabin;
remove the floor tunnel lining;
in the cabin we move aside the carpet covering the body amplifier (in front of the handbrake lever);
remove the transfer case (alternatively, you can simply hang it up, but removing the third support makes it easier to install);
We attach the bracket of the new support to the body of the RC;
we install the transfer case in place, center it in the optimal position, and fasten the side supports;
we combine the third support with the body, drill two holes in the bottom;
Using washers, bolts and nuts (from the kit) we attach the support to the bottom of the body.

Vibration is eliminated more effectively by installing a subframe under the transfer case. You can also make such a device yourself or buy a finished product at a car store.

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:

leave the car in neutral gear;
disconnect the propeller shaft from the transfer case, it is advisable to mark the driveshaft flange and the drive shaft so that during installation, align the driveshaft according to the marks - this way, the occurrence of unnecessary vibrations is eliminated;
dismantle the muffler mounting bracket;
remove the gearbox traverse;
jack up the transfer case, remove the side fastenings of the transfer case;
We treat the places where the subframe fits to the body with Movil;
place the subframe on the gearbox studs;
we mark the attachment points of the subframe on the side members, drill holes, attach bolts to the body;
we tighten all fastenings, except for the transfer case supports themselves;
we perform alignment of the steering wheel;
Finally tighten the transfer case supports.

It should be noted that installing an additional support or subframe on the steering wheel does not always lead to the desired effect; in some cases, vibration only increases.

Combine harvester NIVA SK 5 - do-it-yourself repair and modernization

We study problems and repair methods.

Any car owner definitely doesn’t need to be told why howling and humming are bad. Vibration of the transfer case on a Niva at low speed is quite common. The driver, of course, gradually gets used to many extraneous sounds in the car, but the noise level is high enough to make it impossible to carry on a conversation with passengers while traveling. Due to excessive noise pollution, you will inevitably have to deal with the problem.
