Problems with the inclusion of the first gear and methods of solving the malfunction. The main malfunctions of the manual box and difficult gear shifting. When the engine is running, no gears are included

As on any car, there is also a gearshift mechanism on the VAZ 2110. The VAZ box is a five-speed one, it is turned on by a lever located in the passenger compartment.

In order to be able to fix the problems on your own, you need to understand a little about how exactly the switching mechanism works, which is why there are cases when some speed does not turn on or takes off. And also know how to fix it on your own.

Gearbox scheme

The gearbox device is as follows:

  • to ensure gear shifting in the gearbox there is a primary shaft, which consists of a block of gears. They constantly mesh with the drive gears from the first to the fifth speed (that is, those that are oriented towards driving forward);
  • the secondary shaft is equipped with a driving gear of the main transfer, it also has gear synchronizers, which provide forward movement of the driven gears. There are also bearings plus an oil sump;
  • a VAZ two-satellite differential, with a driven gear of the main drive attached to the flange of its box;
  • the gearbox drive consists of a gearshift knob, a ball bearing, a selection rod, a rod, gear selection mechanisms, as well as gearshift;
  • jet thrust is designed to protect the gearbox from the fact that the gear takes off. It is attached with its ends to the support and the power unit.

How speeds are chosen

A separate important gearbox unit is the gear selection mechanism. It has a special speed selection lever and two locking brackets. One arm of the select lever enables forward travel, the other one serves to enable the rear.

Adjustment

On the VAZ 2110, it is not so uncommon for the gears to turn on poorly, or they are knocked out. A mechanism for adjusting the speed selection drive is specially provided for this.

Adjustment may be needed if:

  • the box was recently removed for repair;
  • one of the gears crashes;
  • the speeds turn on badly or they are simply knocked out when the car is moving.

If you have one of these problems, try adjusting first. Its sequence:

  1. Under the bottom of the VAZ 2110, find and slightly loosen the nut on the bolt tightening the clamp that secures the rod designed to control the gearbox;
  2. Slightly push apart the grooves of the end of the rod with a screwdriver and the gap formed on the clamp itself. This is necessary to ensure easy movement of the rod in relation to the selector shaft. Put the stem in neutral position;
  3. Release the shift knob in the passenger compartment from the cover;
  4. Align the lever according to the special template. This is done as follows: install the template in the window of the rear speed lock bracket. After that, insert the stop of the lever axis into the groove of the template, pressing it without excessive force in the transverse direction;
  5. Then adjust in the rear direction the axial play of the rod, and its axial play by turning to the left;
  6. Install the clamp within a few millimeters of the end of the rod. Then tighten the clamp well with a bolt.

Repair

If the described adjustment did not help you, you need to remove and disassemble the VAZ 2110 gearbox. Special attention pay attention to the fact that it often knocks out the gears, with the help of which the first and second speeds are turned on. Be sure to check each retainer.

They are made in the form of springs, there are three of them. The first retainer is long, it is responsible for the first and second gears. Second - middle, for third - fourth gear. For the fifth, the shortest retainer is used.

Diseases of the checkpoint

There is often a complaint from the owners of the VAZ 2110 that the first speed is difficult to turn on or takes off.

Possible reasons:

  • the synchronizer is often the culprit;
  • perhaps the retainer spring has burst, the lever dangles, the speeds are switched on as they want;
  • stem and fork may need replacement.

Another complaint is that the second gear turns on poorly, it is often knocked out.

The main culprits can be suspected here:

  • the second one flies out most often because the gear teeth do not mesh well with the clutch, which turns on the speeds;
  • the tips of the gear teeth and clutch are already worn out, so the speed does not turn on well. If you do not intervene, it will soon take off;
  • as an option, when it knocks out on bumps, the clutch dies.

Sometimes (although rarely), from the fact that the second does not turn on well enough and flies out, replacing the retaining spring helps. If the speeds often fly out, some of them are difficult to turn on, then half measures will no longer help - a box overhaul is needed.

Whether you carry it out yourself, or go to the service, where they will repair you, as well as adjust the gearshift mechanism, decide for yourself, based on your own experience and skill.

Manual transmission is a mechanism that connects the engine and the driving wheels of the vehicle (transferring the engine torque to the wheels). The main feature is that gear changes are completely controlled by the driver.

For correct operation Manual transmission is very important to know not only. Although the mechanical box is easy to maintain and repair, problems can still arise during operation.

In this article we will talk about why the gears are not included clearly or tightly, the gears are not included at all, etc. We will also consider the main causes of manual transmission malfunctions.

The main causes of poor gear shifting

Among the main reasons, experts identify the following:

  • poorly adjusted manual transmission rocker;
  • clutch drive malfunction (does not completely turn off);
  • defect in the gear selection mechanism of the checkpoint (defects in gears, bearings, etc.);

The first reason why the gears are turned on poorly or the manual transmission lever does not react at all to the driver's manipulations may be an unregulated rocker. The rocker is a kind of rod that connects the gear lever to the gearbox (the lever can also be connected to the gearbox by means of cables).

This problem is solved by adjusting the rocker or replacing it, especially if the plastic bushings in it are worn out. The reason described above only applies to front-wheel drive vehicles, as in the case of rear-wheel drive vehicles, the gear lever is connected directly to the transmission.

A malfunction in the car's clutch mechanism can also cause poor gear shifting:

Another reason for not clearly engaging gears may be a malfunction of parts and mechanisms in the gearbox:

  • wear of synchronizers. Excessive wear of synchronizers occurs in those gears that are included more often, namely in the urban cycle these are the first, second and third gears.

    When driving on highways in high-speed mode, respectively, the synchronizers of the manual transmission upshifts wear out. Wear can be determined by the characteristic crunch when shifting gears. In this case, replace the synchronizers.

  • bearings of manual transmission shafts. Breakdown occurs mainly on vehicles with very high mileage or on vehicles that carry heavy loads due to the nature of their activities. In one and the other case, manual transmission bearings are subject to increased wear. At the initial stage, bearing wear is manifested by the appearance of a monotonous howling sound from the box. If you do not take any measures, then further development appears in the worn bearing, which leads to axial runout of the bearing, followed by its seizure. Parts of a crumbled bearing can get into the gears of the manual transmission and completely disable it.
  • destruction of the gear teeth of the gearbox with physical wear or factory marriage. When operating a car with mechanics, the teeth of one of the gears of the gearbox may fall out, with the subsequent possible destruction of the gearbox.

    As a result, the gear whose gear is damaged stops turning on, and the fragments of the collapsed gear can damage the rest of the manual transmission mechanisms.

What is the bottom line

It is important to understand that a manual transmission is a reliable unit, which normally should not cause discomfort to the driver when driving a vehicle. This means that in case of complete serviceability, the work must be clear and balanced.

If the driver notes extraneous vibrations, noises, etc., there is a fuzzy inclusion or knocking out of the gear while the car is moving, then it is necessary to immediately diagnose the manual transmission.

In this case, it is important to determine not only why the speed on the gearbox does not turn on or the manual transmission gears are tightly engaged, but also to eliminate the cause as soon as possible.

In other words, riding on a faulty gearbox can cause bearings to collapse, etc. As a result, further damage to the components and mechanisms of the manual transmission cannot be avoided, and the cost of repairing the transmission in this case increases significantly.

    What are the reasons for the interruptions?

    The gearbox is not only one of the most difficult, but also one of the most basic units in any vehicle... The causes of malfunctions due to which the first gear engages tightly can be associated with both improper use of the unit and driving on poor road surfaces. In any case, if you do not know why the speed turns on poorly, then this indicates a certain breakdown of the unit itself.

    It should be noted that a similar problem often occurs with older cars that are bought hand-held, and not in car dealerships. Therefore, if you have purchased a used car, then you should not even be surprised at such a problem, especially since such malfunctions will appear in any car sooner or later. In addition, if you try to turn on the speed and this happens, but very badly and with great difficulty, then the unit selector may eventually stop responding to any commands from the motorist altogether. Naturally, not every driver will be able to constantly start driving from second speed, so it is important to understand the reasons why the first gear is hardly engaged.

    Below is a list of breakdowns, as a result of which the gear lever will not shift gears well:

    1. The problem is - the mechanism turns on poorly, the shutdown is incomplete. Often such a problem occurs in domestically produced cars and in most cases it is due to the fact that the mechanical clutch cable flies from the attachment point. In fact, it is not particularly difficult to identify this - if the cable breaks, the pedal will be sunk into the floor and will not move. This, as you understand, is directly related to the operation of the clutch, and not the gearbox.
    2. There was a breakdown in the operation of the control rod of the gearshift mechanism. Then not only the first, but also the rear, as well as the rest of the speeds will turn on badly.
    3. Breakdown of the jet thrust of the unit.
    4. For unknown reasons, the fastening bolts located on the garnish or the selector of the gearbox mode selection rod have loosened. The problem is solved by tightening the bolts.
    5. The gear change drive was incorrectly adjusted.
    6. Plastic elements in the transmission control drive are out of order or have worked out their service life.
    7. The rocker was poorly adjusted. As you know, the purpose of the rocker is very important in the connection between the gearbox and the gear selector, so incorrect adjustment may well be the cause of the problem. In addition, plastic bushings could wear out or fail on this link.
    8. Failure of synchronizers can also be called one of the most common failures in gearboxes. Unit synchronizers are brass bushings required for easier switching between unit modes. Since brass itself is a soft material, it can wear out and wear during the operation of the vehicle. To correctly diagnose the state of the synchronizers, you should pay attention to the operation of the gearbox - if a grinding or unpleasant sound appears when shifting gears, then the problem is in them. Moreover, this sound will appear constantly when you try to turn on the first gear. In the event that only sound appears, but the gearbox selector turns on in one mode or another without problems, then a malfunction will arise soon.
    9. Failure of the gearbox bearings. Such a malfunction does not occur so often, one might even say that it is rare, but any motorist can still encounter it. If you own a car with a manual transmission, then the bearings could jam in it, as a result of which the shaft stops rotating along the trajectory. In such cases, it is difficult to engage the first gear, at other speeds the problem usually does not appear.
    10. The box shaft is out of order. The shaft of the unit is usually not subject to operational wear or very heavy loads, but the malfunction can be caused by a factory defect. In the event that even not very big mistakes were made in production, then the shaft may well break. If this is the case, then the problem of turning on the first speed may only be the beginning of a big breakdown that you have to face. As practice shows, often in such cases the unit itself breaks down completely.
    11. The problem of clutch breakage is relevant for owners of cars with an automatic transmission. There are times when, with incorrect functioning of the clutches, when the first speed is turned on, a jolt occurs, but then everything works fine. The malfunction is solved only by replacing the clutches.

    You, as a motorist, need to understand that a breakdown of the unit shaft or bearings cannot be diagnosed at home. Only experience and equipment will help to understand this reason. Accordingly, if problems arise with the inclusion of the first speed, it is advisable to immediately contact a professional.

    How to turn on the first gear without harm to the box?

    Often, inexperienced motorists, turning on the gearbox selector from second speed to first, may notice how some difficulties appear, in particular, how hard it is to engage the first gear. In such cases, the novice driver often tries to engage the speed using force, simply by driving the selector into the desired position. In no case should this be done, since such actions can be fraught.

    Actually, noticing such a flaw in the manual transmission, motorists have developed a rule - the first speed should be turned on only in order to get under way. In all other cases, the second, third and fourth gears are included. Especially often experienced motorists use this rule, but we want to say from ourselves that this is, in principle, wrong.


    Any auto instructor will tell you that the choice of speed should be based on the driving speed and engine speed. In principle, it is even possible to park normally only at first speed. If you try to park at second speed, you will have to maneuver very quickly, and in such cases a strong load will affect the grip. Actually, as well as on the gearbox unit itself. Accordingly, for yourself you must learn one simple rule - you can turn on the first gear while driving only if the speed is low, and the revolutions crankshaft low.

    Gearbox theory

    Every motorist who understands the structure of the gearbox knows that all modern cars with a manual transmission are equipped with synchronizers. This element is one of the important components of the unit. The purpose of the synchronizers is to equalize the revolutions of all gearbox shafts. In addition, these elements are responsible for painless for the box and shockless gear shifting.

    It should be noted that immediately when the driver pushes the gearbox selector when switching from second gear to first, you can feel an obstacle. This obstacle prevents the activation of the first speed and it is this obstacle that is called the synchronizer. In the event that the gearbox is relatively new or a synchronizer has recently been installed on it, then you will not feel problems with the transition from an increased speed to a reduced one. The inclusion of the first gear will be carried out without any obstacles.


    But if your vehicle has already passed more than a hundred thousand kilometers, then this will directly affect the functioning of some elements of the unit. In particular, in the first place, synchronizers will stop working normally - they simply will not be able to perform the tasks assigned to them initially. Then the motorist is forced to perform various "tricks" that the grandfathers told us about - these are all kinds of peregaski with and so on.

    When performing such tricks, the rebase will perform the function of an equalizer of the gears mated to each other. Thus, if the difference in angular speeds is high, and the synchronizers are worn out enough, the driver will have to accelerate even more. In the event that the angular speeds are the same, the motorist will immediately understand this - the gearbox selector will be able to switch from high speed to low speed without any problems. Thus, making efforts will no longer be advisable.


    Methods for engaging first gear

    So, if the modes are poorly turned on in your vehicle and you have already figured out the reasons and the theory, then let's move on to the most important thing - the methods of engaging the first gear. The simplest method in this case would be to activate the first gear while driving a car. You need to effortlessly push the implement selector forward and do this until the corresponding synchronizer comes into operation. However, it should be noted that this method is relevant for most cars and some trucks.

    It should be borne in mind that in most old trucks this will not work, since the device of the unit itself does not allow this, since they simply do not have synchronizers. In addition, you need to take into account that this method of activating the first speed is hardly relevant if the synchronizer on your vehicle has already worked out its service life. It will simply not be possible.


    Then the motorist will only have to wait a while until the car practically stops to turn on the required speed. Or, using force, turn on the gearshift lever. In principle, neither the first nor the second method can be called the optimal way out in such a problem. As practice shows, it will be best to use the same old-fashioned method with re-gasification.

    How to do this - you can find out below:

    1. So, driving at second speed, start depressing the clutch pedal.
    2. While pressing the pedal, move the gearbox selector to neutral. By doing this, you can deactivate the clutch pedal can be deactivated.
    3. Then, when the pedal is fully lowered, you need to slightly add gas with your right foot while pressing the pedal. In this case, pay attention to the tachometer, which shows the number of revolutions. You need to bring the revolutions up to two and a half thousand per minute, that is, the arrow should be on the number 2500. Here, pay attention to its one important nuance - the greater the difference in the angular speeds of the mating gears of the box, the higher you need to raise the number of revolutions. That is, an indicator of 2,500 is the minimum, add gas if necessary.
    4. Then depress the clutch pedal again.
    5. Further, the gearbox selector should be moved to the activation position of the initial mode, that is, the first speed. Here, also pay attention to the fact that if the selector does not enter correctly into the required position, then most likely you just gave a little gas. If so, then repeat the steps, only add more gas.
    6. Ultimately, you need to release the clutch pedal smoothly, not abruptly. If you did everything correctly, then the gearbox lever without any problems, jolts and extraneous sounds switches to the required position.

    If you did not succeed in doing this, then do not be discouraged - the first time rarely anyone succeeds in performing a double rebase. By repeating the procedure several times, you will be able to remember everything you need to do to correctly engage the first speed. Actually, the same methods allow you to activate the first gear when driving in third, for example, if in an emergency you need to brake with the motor. In this case, the higher the driving speed, the longer you will have to wait for the synchronizers to help you. Or you need to step more on the gas.

    But do not regard the double rebase as a way out of the situation. This method can be called a temporary solution, but the unit will still have to be repaired. Since replacing synchronizers is a rather complicated process, we recommend that you seek professional help. If you nevertheless decide to perform this procedure yourself, then the instructions provided below will come in handy.

    A car consists of many components and mechanisms. In order for the torque energy to go into action, and the car went, you need to use it.But sometimes a situation happens when the gears are hardly switched on when the engine is running. What could be the problem? Today we will try to answer this question.

    VAZ or foreign car - is there a difference?

    To begin with, we note that the principle of operation of the main units is the same for all cars. And such a malfunction can happen to anyone, be it a foreign car, or domestic car... The only difference is the type of drive. The lever is directly connected to the gearbox.

    On front-wheel drive cars, the engine is located transversely to the body. Therefore, a rocker or cable drive is used to drive the box. On the latest models of VAZs (including "Kalina" and "Vesta"), it is the last type of drive that is used. It is more reliable, but there are problems with it. If the gears do not turn on when the engine is running ("Niva" as well), do not panic and take the car to the service. Perhaps the reason lies in trivial malfunctions that you can fix yourself.

    Traction and link

    If you have a front-wheel drive domestic car (nine, "Priora" and so on), and the gears are tightly switched on when the engine is running, you should pay attention to these two details. Often, when starting from a standstill, the gearshift lever begins to rattle convulsively (this is especially true for the Lada Samara family of the first and second generation). The curtain flies out of the mountings. As a result, the gears are poorly turned on when the engine is running. The way out of the situation is to replace the elements with new ones. But this should only be done if you are really convinced of the faults of the backstage by looking under the bottom of the car.

    Wire rope

    If you have more modern car, then the problem may lie in the cable drive.

    On such machines, the gearbox lever does not have a backstage and does not fit into the transmission. If the cable breaks, the gears do not turn on both on the wound and on the muffled engine. This is the main symptom of a breakdown. Output - complete replacement checkpoint cable. Fortunately, it is inexpensive.

    Internal combustion engine mounting pillow

    Oddly enough, but this malfunction can significantly affect the quality of the gearbox. Moreover, due to bad airbags, gears are not included with the engine running, both with manual transmission and with automatic transmission. On some cars, separate supports for the box are installed. Check their integrity and replace if necessary. It is very simple to check - the motor should not jerk from side to side when increasing the speed and on Idling... If the pillows have "sagged", the motor will break the link or the input shaft will jam.

    Fork

    Now let's look at more complex malfunctions, due to which gears do not turn on when the engine is running. UAZ is also susceptible to this breakdown, so you should not ignore the plug. So, on most of the back and four-wheel drive vehicles gears are included by means of hydraulics. When the driver presses the clutch pedal, the release piston is activated and pushes the fluid under pressure. As a result, the fork is retracted to the side, and the disc is disconnected. Inspect the condition of the plug itself and check the system for leaks. If the level in the reservoir is constantly going down (by the way, "brakes" is used for clutching), the boot may have broken. Because of this, we get incomplete squeezing of the fork. The latter also sometimes breaks off, especially on GAZelles. This case looks like this:

    This suggests that the fork was not of the best quality and should be replaced. When buying such critical items, it is not the price that is important, but the quality. You shouldn't give preference to cheap analogs. Renovations can take a lot of your time and effort. On front-wheel drive vehicles, the gearbox must be removed to replace the fork.

    Clutch release

    In the design of the clutch system, a special one is provided.It is he who squeezes the petals of the basket under the influence of the hydraulic drive (when you press the pedal). This bearing decouples the disc from the basket and flywheel. As a result, the motor works separately from the box. If you release the pedal, the element will reconnect the two nodes. Torque will be transmitted as the dry disk makes contact with the flywheel. If the gears do not turn on when the engine is running, most likely release bearing fell into disrepair. What are the symptoms of a malfunction? It is possible to determine the performance of the bearing "by ear". To do this, smoothly press the pedal and then release it. There should be no noise, whether it is a disengaged or disengaged clutch. We also note that to replace the clutch release (even on rear-wheel drive cars), you will have to completely remove the box with the "bell". This element is installed as in the photo below.

    After replacement, the noises should disappear. But if even after that the gears do not turn on when the engine is running, it is necessary to inspect the

    Basket

    This element is installed on all vehicles with a manual transmission. As for the "automatic machines", then a torque converter is used here or, in common people, a "donut". So why don't the gears come on while the engine is running? Over time, wear occurs on the clutch basket petals. It bends or breaks. As a result, the gears are not included when the engine is running. Visually inspect the condition of the item. If the petals are damaged, then the element must be replaced.

    But this is not the last reason why gears do not turn on when the engine is running. If the speeds are tightly included, and the car shakes at the start, the fault is the worn out clutch disc. The element looks like this:

    This is what the new element looks like. After 100 thousand kilometers, it will take on a slightly different look.

    If the disc is worn out, burnt, or the springs have come out on it, it should be replaced. By the way, there is a development on the flywheel, but it is not so significant.

    How often does the clutch disc change?

    There is no specific regulation here. Clutch disc resource is a subjective concept. It all depends on the loads - whether you used a trailer, how much you overloaded the car and how often you started with wheel slip. Each blow from the flywheel falls precisely on the clutch disc, because its main task is to transmit torque, and to do it as smoothly as possible. The resource can range from 30 to 200 thousand kilometers or more. The service life directly depends on the driving style and the load conditions of the vehicle.

    Synchronizers

    In the event of a malfunction of these elements, the gears can be switched on, but with great effort and with a characteristic crunch (as in the 53rd GAZon). The synchronizers themselves are soft gears that smooth out the angular speeds of the shafts. The elements are usually made of copper and brass and are therefore subject to wear and tear. As the development progresses, the gears will become more and more difficult to engage, up to the use of a double squeeze with re-rotation.

    Transmission shafts

    This is one of the rarest reasons, but it should not be ruled out either.

    So, the gearbox shafts themselves fail. For example, the second or fifth gear refuses to turn on. Determine the degree of wear only after dismantling the transmission and completely opening the elements. The shafts are not machined, but replaced with new ones. That's all.

    Conclusion

    So, we found out why the gears do not turn on when the engine is running. As you can see, most problems can be identified and fixed by hand. The main thing is to identify the breakdown in time and fix it, otherwise you risk getting to an expensive repair.

    One of the malfunctions of a manual transmission is a fuzzy engagement of gears or the inability to engage them.

    In such a situation, there may be several reasons for the malfunction and it is necessary to immediately determine whether they relate to the gearbox itself or the problem is related to the clutch assembly. So, if all gears are turned on clearly on an uncranked engine, and problems appear when the engine is running, then most likely the reason lies in the clutch.

    In addition, the problem with the inclusion of speeds can be caused by a malfunction of the gearshift drive. In this case, the shift lever can be structurally located on the manual transmission itself (VAZ 2101-07), or through a system of rods or cables from the wings to the gearbox.

    The principle of operation of the transmission is the same for all brands of cars, regardless of whether it is a foreign car or a domestic car.

    In cases where questions arise with the inclusion of a transfer, it is not necessary to contact the professionals of car services, you can try to solve them yourself.

    Let's analyze in order what can affect the poor inclusion of speeds or the impossibility of their inclusion.

    Shift link and pull rod

    On front-wheel drive models, the rocker is connected to the manual transmission by means of rods, in the event of a malfunction of which there may be problems with shifting gears. The shift lever drive can also be used on rear-wheel drive models, for example, BMW 3, and others.

    On the wings, there may be problems such as loosening of its fastening, fracture of the shift knob. In the drive system, there may be such malfunctions as loss of the thrust fixing stopper, loosening of the fastening of the gearbox drive slider.

    To identify a malfunction, it is necessary to revise the backstage in the car and inspect the drive under the bottom of the car.

    On more modern models, the car drive is made by means of a cable. If the cable breaks, gear shifting becomes impossible.

    Clutch drive

    In the event of a drive malfunction, for example, a leakage of the hydraulic connection, an incomplete release occurs, which also leads to the fact that the gears are difficult to engage or not engage.

    Engine and gearbox mounts

    When worn out, when they have sagged from time to time or burst, then the drive of the wings will work with a bias and its breakage is possible. Also, sagging pillows can provoke a seizure of the input shaft of the gearbox.

    This is especially critical for rear-wheel drive cars, when the manual transmission mountings sag, causing a skew, which makes it difficult or impossible to turn on the speeds.

    Shift fork

    The fork is used to transfer force from the clutch pedal to the clutch block through the release bearing. In cases where the fork forms a crack, or it comes out of engagement with the release bearing, gear shifting becomes difficult, or even impossible.

    A plug revision or replacement is required.

    It is necessary to transfer the force from the fork to the petals of the basket, which in turn diverts the clutch disc from the engine flywheel, breaking the torque (the motor works separately from the transmission), making it possible to turn on the required speed.

    When the bearing is worn out, the speeds will be difficult to engage or shifting will be impossible altogether. The problem is solved by replacing the release bearing.

    Basket

    When the petals of the basket are worn out or a crack appears in the petal disc, full squeezing does not occur, as a result, the driven disc does not completely move away from the engine flywheel, making it impossible to engage the gear.

    Clutch disc

    When the disc damping springs are worn out or their fastening is loosened, the gears will be difficult to engage and shaking will be observed power unit... Also, when replacing the clutch disc, it is possible to install a product whose thickness is higher than the tolerance, which leads to the impossibility of completely disconnecting the disc from the flywheel, since there is not enough basket spring travel, which also leads to the impossibility of engaging gears.

    The problem is solved by replacing the disk.

    Synchronizers

    These elements are made of soft materials (copper, brass) and therefore are often subject to wear. Synchronizers especially suffer from a sharp release of the clutch pedal at sudden starts, which leads to shock loads and rapid wear of the surface of the synchronizer cone or its breakage.

    Gearbox synchronizer - yellow

    When they are worn out, switching will also be difficult or impossible.

    Also, the inability to engage gears can be affected by the wear of the gearbox shafts, when it will be impossible to engage the second or fifth gear. This malfunction requires complete disassembly Manual transmission and shaft replacement.

    Summary

    If any manifestations of difficult gear shifting appear, it is recommended to immediately identify the malfunction and take measures to eliminate it, since further operation of the manual transmission with a malfunction, as a result, will result in a complex and expensive transmission repair.
