The nuances of pricing when replacing a gearbox

Each potential customer of repair services is concerned about the question how much does a gearbox for a Chevrolet Niva cost, price recovery will be on par with that when replacing the transmission unit or lower? We hasten to answer it: it all depends on the complexity of the damage to the unit. Sometimes it's more efficient to replace the gearbox and not mess with the bulkhead. Inexpensive cost used gearbox VAZ 21214, price unit in this case is determined by its margin of safety.

When replacing, the cost of the service consists of:

• diagnostics of the box in order to determine its actual condition and maintainability;
• selection of the unit for exchange;
• dismantling and assembly works.

High quality used box for Chevrolet Niva, price which in our service is affordable, can last for many years. We bring to the attention of car owners units of our own bulkhead, with a guaranteed margin of safety.

Chevrolet Niva gearbox repair: financial aspects

Pricing for the repair of transmission units also provides for taking into account many factors, criteria and indicators. First of all, this is the current state of the unit. In other words, the more elements of the box to be replaced, the more expensive the repair will cost.

The type and quantity of spare parts used also plays a role. In order to save money, used elements are often installed. Sin this, as a rule, master-private traders. Moreover, the status of the elements is not taken into account when forming the price of the service.

Professional repair of gearbox VAZ 21213 (5-mortar) provides for the use of new original parts, high-quality lubricants recommended by the manufacturer of the transmission unit. This is one of the reasons to contact a specialized service, and not a private garage.

The cost of repair services includes diagnostics of the unit, dismantling, reassembly, installation, testing in operating modes. As a result, the car owner receives a serviceable vehicle that provides comfort and safety of driving. High-quality repair of the checkpoint also ensures the preservation of the full functionality of the Niva as an SUV.

Savings or cost optimization?

When replacing, repairing the gearbox, you can save money. There are several ways. It is rational to cooperate with a specialized workshop. The services of specialists here can cost a little more than in a private garage. But the costs are more than paid off by the stable operation of the restored or replaced transmission unit. Contacting a car service can be considered not so much saving as cost optimization.

If the price of services is a priority for you, you can consider the proposals of private masters or try to fix the checkpoint malfunctions on your own. But be prepared for possible negative consequences. And keep in mind the fact that after a handicraft repair, a professional may be required. Instead of saving, respectively, you will get a doubling of costs.

Why does the gearbox break and what to do about it?

Niva is included in the list of the most reliable vehicles of the domestic auto industry. But the anti-vandal machine is still not. Breakdowns, given the purpose of the transport, the specifics of its operation, take place and do not happen so rarely. When it comes to transmission buy gearbox for Niva 21214 in Moscow wouldn't be too hard today. The same applies to other elements of the system. Auto-mechanical, auto-mechanic services were and remain available. How much does it cost to repair a checkpoint on the Niva? It all depends on the specifics of the service, the scope of work.

TOP 5 causes of transmission malfunctions

If yours failed Chevrolet Niva, gearbox replacement or its repair is a rational decision. But at the same time, it is important to understand the reason for the failure of the transmission unit in order to prevent this problem later.

We present to your attention 6 reasons for the occurrence of breakdowns in the gearbox of a modern Niva (regardless of modification):

• Development of a resource of details, natural wear of elements. This is a common reason due to the physical and mechanical properties of the materials from which the parts of the box are made. Natural wear and tear is inevitable during the operation of the car.
• Handicraft repair of the gearbox, the use of spare parts of inadequate quality. Here, it seems to us, comments are superfluous. Do you want to gearbox repair Niva 21213 was of high quality, most effective? Trust professionals, buy original spare parts.
• Neglect of maintenance. Niva, as mentioned above, the car is reliable. But the absence of visible signs of malfunctions is not a reason to refuse scheduled maintenance. Subsequently, repairs can be more expensive, more difficult.
• The use of low-quality lubricants. Saving on oil is extremely irrational. Lubricants other than those recommended by the gearbox manufacturer may contribute to premature wear of parts.
• Operation of the car, as they say, wear and tear. Niva is able to withstand extreme loads. But constant hard traffic significantly reduces the period of its maintenance-free use.
• Violation of operating conditions, driver errors when shifting gears, working with the clutch. The user factor is the most significant. Most often, it is he who causes the failure of transmission elements.

How do you know when it's time for a service?

Box faults report themselves in a variety of ways. Even a novice, inexperienced driver can suspect problems. If the transmission unit does not behave as usual, it does not hurt to look into the service. Has the unit been badly damaged (e.g. in an accident)? Consider replacing it.

If you need gearbox for Chevrolet Niva, price which is available, pre-order the unit by phone. This will save time.

Typical manifestations of breakdowns of the Niva checkpoint

The gearbox in the Niva car (all modifications) shows symptoms of malfunctions in a similar way. These manifestations can be divided into 3 groups:

• sound;
• mechanical;
• mixed.

Repair of the checkpoint Niva (5-mortar) in each case depends on the location, number, complexity of breakdowns.

It should be noted that the symptoms in different cases may be similar. Thus, it is impossible to pinpoint the root of the problem by sound effects alone. Accordingly, in the presence of any gearbox malfunctions, one cannot do without a comprehensive diagnosis of the transmission unit in a specialized workshop.

Gearbox repair, repair of transfer case Niva 21213 in Moscow on favorable terms offered by our workshop. If you need to quickly put the car on all 4 wheels, welcome!

Heed the box

Let us consider in more detail the first group of symptoms of gearbox breakdowns - the sound accompaniment of the operation of the transmission unit. The following effects are possible:

• Extraneous noise when shifting gears. These symptoms are quite varied. With sound, a specific gear or several speeds may be included. The sound can be single, periodic. Constant noise is also sometimes present.
• Uncharacteristic sound when the gearbox is in neutral.
• Noise during operation of the box, regardless of the active speed mode, related factors such as a depressed clutch, etc.

In the first case, one can suspect a blocker malfunction, loosening of the box fasteners (most often, a loosening of the threaded connection is observed). Also, noise when switching speeds is provoked by worn synchronizer clutches. A typical problem is the incomplete disengagement of the clutch. The problem can be user and technical.

Noise in neutral most likely indicates that the drive shaft bearing has worn out. Such symptoms also appear when the level of lubricating fluid in the transmission unit decreases.

If the box is noisy, regardless of the gear, speed, it is worth checking the main elements of the unit for wear. Chevrolet Niva checkpoint repair cost will have an appropriate scope of work and the number of replaced parts.

Pay attention to mechanics

Repair of gearbox VAZ 2123, 2121, price which may be different, is inevitable in cases where switching speeds is difficult or impossible. Also, a visit to the service cannot be avoided if the speed modes turn off spontaneously.

Bulkhead checkpoint VAZ Niva (5-spupka) will be required if one or more gears are knocked out. This symptom indicates the presence of a serious technical problem. The range of localization of faults is quite wide here. Gear knockouts can be caused by:

• worn intermediate shaft bearings;
• broken shift rod;
• defective synchronizer clutches;
• stuck drive cable.

The problem is easier to solve if the gears are knocked out due to a defect in the fastening of the box. It is enough to tighten the threaded connections, and the unit will start working normally.

How to read the complex of symptoms?

Often box malfunctions give mixed symptoms. For example, the transmission unit may work with an uncharacteristic soundtrack, while oil is still leaking from it and the gears sometimes jam. In such cases, complex diagnostics is indispensable.

Do you want to make a diagnosis quickly, at no extra cost? Come to our workshop. We perform all types of auto repair work, including repair of transfer case Niva Chevrolet, restoration of the checkpoint.

auto gear switch

The function of the transmission is to ensure the optimal operation of the motor in various driving modes. The purpose of the gearbox (gearbox) is to change the frequency and torque to a greater extent than the engine can provide. The Chevrolet Niva motor has 800-5400 operating revolutions per minute, the maximum torque value is reached at 3000 revolutions per minute.

The Chevrolet Niva has a five-speed gearshift mechanism with a three-shaft scheme. The Chevrolet Niva 21074-1700005-40 manual gearbox is based on the classic 2107 gearbox, but has certain differences:

• no retaining and centering rings at the end of the secondary shaft;
• the speedometer cable drive (gear inside the Chevrolet Niva gearbox) was replaced with a remote bushing;
• the flange of the output shaft bearing on the Chevrolet Niva holds only the bearing itself, the axis of the intermediate gear is attracted to the gearbox housing with a nut.

In cars of the Niva Chevrolet family, the gear shift mechanism quite often fails, because the reliability of this unit in Russian cars leaves much to be desired. Manual transmission has a complex device, its replacement is quite expensive. Therefore, if repairs are possible, Chevrolet Niva owners prefer to completely replace the gearbox.

The oil protects the gearshift mechanism from wear

In order not to resort to radical measures for as long as possible, it is recommended to monitor the oil level in the Chevrolet Niva gearbox. A change in the color of the lubricant indicates troubles threatening in the near future. Normal oil is clear and viscous. When measuring the lubricant level, rub a drop of the substance with your fingers. So you can feel and visually determine the state of the oxoli. The manufacturer recommends changing the oil in the gearbox of the car every 45 thousand kilometers.

Changing the lubricant in the gearbox

To change the lubricant in the Chevrolet Niva gearbox, you will need:

• key for 17;
• hex wrench 12;
• container for draining used oil.
• The procedures must be performed in a certain sequence.

Place the container under the drain hole of the Chevrolet Niva gearbox crankcase. For easy draining, unscrew the oil fill plug, then open the drain plug and wait until all the grease has drained into the container. Clean the drain plug from dirt and screw it into the drain. Oksol, which includes various contaminants, will look like a cloudy dark liquid. Before pouring fresh oil into the box, it will have to be washed.

Pour 0.9 liters of flushing lubricant into the corresponding hole in the crankcase, tighten the plug. Hang the rear wheels, start the engine in 1st gear. Shut off after a couple of minutes, drain the flush. Clean the drain plug from any dirt and screw it on.

Pour in 1.6 liters of fresh grease. It is convenient to add oil to the box with a syringe or a special device. Screw the oil filler plug into place. The grease from the Chevrolet Niva gearbox is easily drained hot after a trip.

When measuring the oil level after the car has traveled 45-50 thousand km, the owner may find that the lubricant disappears somewhere at a terrible speed after filling. At the same time, the gear shift mechanism makes a rattle when the Chevy Niva moves. This is due to wear of the output shaft seal. Through the gaps formed between it and the shaft, oil flows out of the box.

Reducing the level of lubrication is fraught with increased wear and adversely affects the gearshift mechanism.

The gearbox of this car

To avoid unnecessary expenses, you need to replace a worn oil seal in a Chevrolet Niva. This is a difficult but necessary operation. To carry it out you need:

• key for 30;
• screwdriver;
• hammer;
• mandrel.

Dismantle the transmission promshaft, remove the centering ring seal and unscrew the flexible coupling flange nut. Remove the ring, as well as the flange lock washer and the “helicopter” itself. An oil seal is now visible between the gearbox rear cover housing and the shaft. It must be removed with a screwdriver. Lubricate the new oil seal with sealant and press it into place by tapping the mandrel with a hammer. As a mandrel, you can use the old stuffing box. Assemble the mechanism by doing all the steps in reverse order. Add oil.

When is a repair required?

After about 50 thousand kilometers, the gearshift mechanism of Chevrolet Niva cars begins to “please” the owner with a hum and uncharacteristic noises. These are the first signs of worn gears and bearings. If you carefully monitor how the gearbox works, you can determine what exactly is faulty inside the Chevrolet Niva box:

• noise, rattle, knocking when driving or warming up the engine - wear of bearings, gears, synchronizers, breakage of the input shaft stopper, axial displacement of the shafts;
• impact when starting or shifting gears - wear on the connection of the output shaft and the "helicopter";
• refusal to turn off the gear - the gearbox rocker jumped into the fork of the stem of another gear, the synchronizer jammed;
• difficult gear shifting - the lever is deformed, jumped off the stage, shift forks are deformed, wear on gears, synchronizers, balls or rod sockets, breakage of the synchronizer spring;
• knocks out gears - wear of the forks, grooves of the coupling for the fork, gear.

All this indicates that the time has come to repair the Chevrolet Niva gearbox. To do everything yourself, you need to know how the gearshift mechanism works. Then you can sort out the Chevy checkpoint with your own hands.

The dismantling of the gearbox on a Chevrolet Niva car is performed in order to replace the failed elements. To carry out repair work, remove the box, thoroughly rinse it, cleaning it of dirt and, if possible, blowing it with compressed air, and place it on a convenient workbench for later disassembly. Prepare a standard set of tools and do the following sequence of actions:

• Drain the oil from the box crankcase into an empty container by unscrewing the drain plug at the bottom of the crankcase.

• Using an open-end wrench, unscrew the three nuts securing the gear selector mechanism and remove it.

• Remove the center ring seal.
• We fix the flange from turning and unscrew its fastening nut. Simultaneously with the unscrewing of the nut, the centering ring itself is pressed from the shaft.

• Remove the lock washer and flexible coupling flange from the shaft.

• Having unscrewed two nuts, we remove the bracket for fastening the exhaust pipe.

• We unscrew the nuts securing the bottom cover to the crankcase and prying with a small flat screwdriver, remove the cover and the sealing gasket located under it.

• Next, remove the inner bearing ring of the secondary shaft bearing, the spacer bushing and the oil slinger from the shaft.
• Remove the clutch release bearing from the shaft.

• We unscrew the two bolts securing the cover of the clamps, after which we remove the cover, the gasket installed under it and take out the springs of the clamps and turning the crankcase over, take out the balls.

• With a small drift, we press out the rear bearing of the intermediate shaft, applying light blows to the outer ring.
• Next, remove the spacer from the output shaft.

• Remove the outer ring of the bearing together with the rollers.
• Then remove the inner ring.
• Remove the intermediate shaft from the crankcase.

• Turn the gearbox over and remove the blocking cracker of the third and fourth gears.
• After that, we push this rod a little so that you can remove the cracker.

• Using a screwdriver, we take out the intermediate blocking cracker and completely remove the stem.

• Remove the 3rd and 4th gear fork.
• Next, with a socket head with an extension, unscrew the bolt securing the first and second gear forks.

• We take out the rod for engaging the first and second gears from the crankcase.
• We turn the gearbox over and take out the blocking cracker of the first and second gear engagement rod from its seat.

• We remove the fork of inclusion of the first and second gears and the input shaft assembly with the needle bearing.

• With an impact screwdriver, we loosen the tightening of the three screws securing the lock plate of the intermediate bearing of the secondary shaft and the axis of the intermediate reverse gear. We unscrew the screws and remove them.
• We unfold the lock plate in such a way as to remove it from the groove of the axis of the reverse intermediate gear.

• Remove the axle and lock plate.

• We unclench the retaining ring of the intermediate bearing of the secondary shaft and remove it.
• We take out the locking key from the groove of the secondary shaft.

• Using a flat screwdriver as a lever, remove the bearing from its seat.
• Then we feed the secondary shaft a little forward and take it out.

• By striking with a drift on the outer ring, we press out the rear bearing of the secondary shaft from the rear cover. We remove it and the distance ring installed between it and the stuffing box.
• And at the final stage, remove the rear bearing seal.

This completes the repair work.

Malfunctions in the operation of your favorite car are always unpleasant, costly and cause a lot of inconvenience. Especially when it comes to transmission problems. In this article, we will talk in detail about the problem of the Niva Chevrolet knocking when shifting gears and show you how to make repairs yourself.

Box problems

The Niva Chevrolet car, and in particular its gearbox element, as they say, is good, but with its own “features”. Somewhere after the first 50 thousand kilometers, the device begins to show teeth. There may be a hum or unusual noise. Similar features" make it clear that the bearings or gears have worn out. If you watch the checkpoint for some time, you can determine what exactly will have to be replaced. What other problems can occur in the operation of the gearbox?

1. Noise, grinding or knocking when the car is moving, and sometimes when warming up.
2. Bumps while shifting gears.
3. The gearbox may refuse to disengage a particular gear.
4. Deformation of the lever, which promises complications in the process of shifting gears.
5. Also, transmissions can simply knock out.

For each item listed above, there are reasons and ways to solve them. But today we will consider a specific problem - the knock of the Chevrolet Niva gearbox and carry out repairs with our own hands.

Knocking when the car is moving or at the time of warming up indicates that the bearings, gears, shaft (primary) or axial ones have worn out in the gearbox. Actually, it is sometimes very difficult to determine what exactly caused it. And if you do not have the opportunity to carry out a complete replacement of the gearbox, then the only option for you is to remove the device manually, disassemble and make minor repairs.

Scheme and checkpoint device

In order to proceed with the removal and disassembly of the box, you first need to familiarize yourself with the diagram of the Niva Chevrolet checkpoint device in order to better understand how the repair will take place.

DIY repair

Gearbox knocking is a fairly common disease and not very pleasant. Every time you switch to listen to a rattling sound, you won't get any nerves. But it is still possible to cure the checkpoint by carrying out appropriate repairs.

In order to remove the knock of the box, you must first remove it. To repair the box, you need to have with you the keys (10, 13, 19), the key (hex) for 12, a screwdriver and pliers. So let's get started:

1. Park your machine on a hill or in a hole.
2. Disconnect the battery terminal and pour out the oil.
3. Get inside the car. Remove the handles from the levers, as well as the handouts, the element casing and the cover.
4. Remove the cover, boot, blockage sensor connector. Remove the gear lever itself.
5. Adjust the gear that gives back, remove the locking sleeve.
6. Try to mark the cardan flanges and also the handouts, so that later you can assemble everything in the correct order.
7. Remove the cardan (which is the front one) and the washer (which is the oil deflector).
8. Did you see the flange (look at the output shaft)? Unscrew the nuts of the elastic coupling from it (this is done with a size 19 wrench).
9. Unscrew the nuts on the pillows to the very, very end of the studs and remove the transfer case.
10. Now you need to unscrew the bolts from the cylinder and the starter itself, after removing the cotter pin and the spring next to it. This action requires an extension cord.
11. Move the starter closer to the radiator.
12. Disconnect the sensor that is responsible for the lights (reverse), unscrew the muffler clamp, as well as the bolts from the crankcase and the traverse nuts.
13. Remove the bolts that hold the box closer to the engine. Carefully disconnect it, just try not to let it hang with all its weight on the input shaft.
14. Slightly rock it from side to side and gradually move it back until you reach the stop.
15. Lower the crankcase down, pull the rocker out of the hole.

Congratulations, you have removed the gearbox! In order to continue the repair, it must be disassembled. It should be disassembled slowly, immediately prepare yourself a workplace. Tip, lay out all the removed parts in exactly the same order as you remove them, this will greatly simplify the reverse process. As you disassemble the device, observe how the bearings, gears, axial ones behave, whether there are any scuffs, how the input shaft behaves. You may not have to completely disassemble the element, for example, it is very easy to identify bearing wear when you remove the bottom cover, move them a little, if any of the bearings are displaced, then it is worn out and needs to be replaced. So let's get on with the renovation. You need to do the following:

1. Loosen the shank nut first. Carefully remove the helicopter flange and the mechanism that selects the gear. Check the yoke for cracks.
2. Now remove the back cover. If suddenly it is impossible to remove it, then push down the bearing race. It is on the clips that the condition and nature of the bearings are inspected. If you decide to replace them, then you will need to pierce the bearing (already the output shaft) down, remove the clutch housing and check the spring washer.
3. Now take out the clip, the bushing (which is remote), and the washer. You will have to disassemble the locking mechanism. To do this, unscrew the gear bolts, as well as the bolt (look at the output shaft). Lastly, remove the fungus and the ring.
4. Completely remove fifth gear. Disassemble the gear. Remove the fixing ball, for this you need to push it inward. Unscrew the bolt of the third and fourth speed forks, extend the stem, remove it and the cracker. Dismantle the fixing ball and cracker. And by analogy, disassemble the first and second gear.
5. Unscrew the fifth speed fork. Remove the rear gear. Don't forget to check the clearance.
6. Take out the middle bearing, remove the front one, move the shaft back, and then pull it forward. The clip that is inside must be knocked down with a chisel.
7. Remove the 1st, 2nd, 3rd and 4th gear forks. Also remove the input shaft, the locking ring must be removed, use a hammer or puller for this. Take the pliers and pull out the ring. Carefully inspect the needle bearing.
8. Swinging from side to side, remove the bearing. The shaft must be removed. Remove the 1st and 2nd speed gears and the 1st, 2nd, 3rd and 4th hub clutch. If you find a malfunction, you need to open the stopper, remove the third and fourth hubs of the third speed. Replace seals.

Hooray, you're done, you've opened the box! In order to remove the knock, you need to identify the part that has been damaged or worn. After you find it, continue repairing the box, replace the damaged part, assemble the device in reverse order and put it in place.

Video "Removing the gearbox"

How to properly shoot our checkpoint you can see in this video.

Chevrolet Niva has a permanent all-wheel drive, is equipped with a five-speed manual gearbox and a two-speed transfer case with a low range and locking center differential.

How does all-wheel drive work on Shniva.

The mechanics of the VAZ 2123 was created according to the so-called three-shaft scheme, that is, with an intermediate shaft, and has 5 synchronized gears for moving forward and one back.

In general, the box is not very clear and rather tight. It only gets worse with mileage. By about 50-100 thousand kilometers, a serious repair is usually brewing with a complete disassembly due to the replacement of any bearings. They make themselves felt by noise inside the gearbox housing. Most often, the input shaft bearing breaks, it is easy to check it, if the noise disappears when the clutch is depressed, then it is for sure.

The weakening of the backstage clamp leads to a displacement of the handle: if it goes forward, then it stops turning on or the fifth gear is constantly knocked out, if back, then reverse. Some owners complain about strong vibrations of the manual transmission lever at certain engine speeds.

The entire clutch runs for about 80 thousand km, but some owners still have to replace the release bearing already at 40 thousand. The boot of the clutch slave cylinder can break even on a new car.

If we talk about transmission problems, then everyone immediately remembers the insane howl and strong vibrations at certain speeds. However, do not forget about the constant modernization of the model. For example, the crosses of the cardan shaft in 2010 gave way to CV joints, double-row output shaft bearings appeared. After that, the car became much more comfortable.

The transfer case control mechanism does not have synchronizers, so it turns on and off in a specific way. The driver needs to catch the moment of coincidence of the teeth and grooves of the clutch lock by moving the machine slightly back and forth.

Tension owners and constant leaks. Weak points are almost all oil seals, in the gearbox there is also a speedometer drive, and in the razdatka there is a lock-on sensor and a downshift engagement rod. In 2011, the supplier of oil seals changed and there were much fewer leaks.

According to the manufacturer's recommendation, the oil in the box, razdatka and bridges must be changed every 45 thousand kilometers. Typically a 75W-90 or 80W-90 transmission is used. Replacement requires: in a manual transmission - 1.6 liters, a transfer case - 0.8 liters, a front and rear axle differential of 1.2 liters each.
