Gearbox 2110 2112

Gearbox 2110 2112 is of a mechanical type, having two shafts and five gears for forward movement and one in reverse. All forward gears at the gearbox have synchronizers. It has a joint design with a differential and main gear. The body is made of three parts. The material used is aluminum, which has such advantages as reduced weight, lack of corrosion and high strength.

Like any other gearbox 2110 2112 is designed for mechanical connection of the engine and wheels, which ensures the movement of the car. By changing gears, we move at one speed or another. First gear is used to start driving, and fifth gear for highway driving.

The VAZ 2110 2112 gearbox differs from the gearbox of eights and nines. This is a difference in the clutch housing and the design of the starter mounting. Gear ratios 1 – 3.636, 2 – 1.95, 3 – 1.357, 4 – 0.941, 5 – 0.784, reverse gear -3.53. The final drive has a ratio of 3.7 or 3.94.

The VAZ 2110 and VAZ 2112 gearbox is a reliable unit. Doesn't require very close attention. It is necessary to change the oil every 75,000 kilometers, which means this should be done infrequently. The replacement itself is quite simple. After driving a little, thereby warming up the oil, we unscrew the drain plug, having first placed the car over the pit or raised it on a lift. After the oil has drained, fill in new oil. Its level should be located between the two marks on the level indicator. That's all the wisdom.

WHEN INSTALLING:

The main pair is 4.1 - the engine is unloaded, it is easier for the motor to spin the wheels, the dynamics of the car increase, the gears are shortened, the maximum speed drops by ~20 km. per hour (at 160 km/h, tachometer revolutions are 5 thousand), fuel consumption + 1 liter. (due to changes in driving).

The main pair 4.3 is the same as 4.1 + 5 mph. in all gears.

Ch. pair 4.1 or 4.3 + sports series (06, 07 or 08): dynamics (fast acceleration due to the main pair) + long gears, mainly 1st and 2nd spin up to the maximum.

Ch. pairs 4.5 and 4.7: gears are even shorter than 4.1 and 4.3 (maximum speed at 5 thousand tachometer revolutions is 140 km/h), recommended use: when towing and transporting heavy trailers.

Ch. pairs 4.9, 5.1, 5.3 and 5.07: used only on steep slopes and climbs (maximum speed 110-120 mph)

Rows: 011, 012, 018 - installation with standard chapter. a pair of 3.9 for forced engines 1.7, 1.8 and 2.0l.

26th cam row (semi-automatic) - gear shifting is carried out without using the clutch, squeezing the clutch is only necessary when starting and stopping.

6th gear retains maximum speed when using ch. couples and sports. row.

Locker (locking differential):

Worm (screw) - increases the vehicle's off-road capability; when one wheel slips, the second wheel automatically turns on (it also turns on when turning).

Disc (friction) - ensures constant rotation of 2 wheels. (Recommended for use only off-road)

Unacceptable:

• Shift into gear with a crunch.
• Switch quickly from gear to gear.
• It is rude to engage the gears (if the gear does not engage, do not forcefully engage it, but release it again and press the clutch, and repeat its engagement).

If you violate the above instructions, the service life of the gears, and accordingly the gearbox, will sharply decrease!!!

Also, it is highly undesirable to start with slipping. Such systematic driving leads to the collapse of the differential, which breaks the gearbox (the large casing suffers), and the car remains unable to move. BE SURE to check that the clutch is in good condition! The clutch is checked like this:

• Correct adjustment of the clutch pedal (pedal at the level of the brake pedal)
• Squeeze, pause for 2 seconds, reverse gear should engage without crunching. If the reverse gear engages with a crunch or does not engage at all, then this indicates that the clutch is “driving” and needs to be changed immediately! With such a malfunction, there is a large load on the front gear synchronizers, which leads to their rapid wear and failure.

Transmission tuning. How to choose gear ratios for a gearbox?

Most of the technologies used in transmission tuning are proven in motorsports. The transmission of any, especially a sports car, is the most important mechanism for realizing the dynamic characteristics of the engine. Even with a relatively weak engine, the car can be fast due to correctly selected gear ratios.

In motorsport, synchronized (as on 'road' cars) and non-synchronized (cam) gearboxes are used. Based on the shifting principle, they are divided into conventional (H-pattern) and sequential (with sequential gear selection, like on motorcycles).

In cars of a fairly serious level of preparation, cam gearboxes are used. They have a number of advantages - they can withstand higher loads (due to the shape of the tooth and the gear-cam clutch engagement), allow experienced pilots to spend less time changing gears due to incomplete squeezing of the clutch or without squeezing the clutch at all, they do not destroy synchronizers (which are simply No).

For normal road traffic, cam gearboxes are practically unsuitable, since they are quite noisy (due to the operation of spur gear pairs), “hard” when engaging a gear, and have a relatively short resource. In addition, they are disproportionately more expensive than synchronized ones and require regular qualified maintenance.

Synchronized gearboxes differ from standard ones only in gear ratios. In some cases (VAZ-2108 and -2110) it is possible to add a 6th gear. The correct selection of gear ratios of the main gearbox pair, the input shaft and the driven gears of the secondary shaft is the key to coordinated operation of the transmission. Gear ratios are selected depending on the power and torque characteristics of the engine, wheel size and, most importantly, on the wishes of the car owner.

How to set preload

Preload adjustment is carried out by installing a package of special spring washers that push the gears inside the lock. A complete package of such special washers, when folded together, is 1 cm thick, but all the washers are different in thickness so that you can adjust the differential preload moment.

To adjust the preload you will need:

• pointer torque wrench (a wrench with clicks is not suitable, it will take a long time to set up);
• a homemade special part made from a simple internal grenade (cut off and a bolt welded to it) - see the video below;
• set of spring washers (rings);

Procedure for adjusting preload:

1. Disassemble the locking differential (remember the sequence). After removing the cover, pull out the axle shaft auger gear; behind it comes a narrow gear with a large internal hole, but which has a side; then come those same adjusting spring washers. You can pull out the screw satellites (the preloads themselves) to check how much wear they have.
2. Install new washers.
3. Collect.
4. Using a torque wrench and a special homemade part, we determine the tightening torque. When the key begins to turn, at this moment the arrow shows the tension torque.

This video discusses the option of adjusting the locking washers of a VAZ 2108 car.

A preload of up to 5 kg does not flatten the washer to a flat state; such a tension moment is considered a resource tension. Locking with a tension of up to 5 kg will help not significantly lose its characteristics for about 4 years. Any blocking with tension in the first couple of months loses about 1 kg of tension.

Experts recommend making a preload of no more than 5 kg for a self-locking front differential, and no more than 7 kg for a rear differential. At a maximum differential preload of, for example, 9 kg, all spring washers will already be pressed and the effect of the springs will be lost.

Do-it-yourself tuning of the VAZ 2109. Replacing the carburetor

The purpose of this work is one - to increase power. Here, as they say, one head is good, but two are better. One carburetor is not needed, two carburetors are needed. This technological modification gives the engine additional power. You can also treat the carburetor intake manifold. Chassis tuning is a separate topic and consists of two blocks: suspension tuning and brake tuning.

The suspension can be improved in three ways:

1. Replace the old with the new. Update the mechanism in full. Simply install a proprietary, branded gas-oil shock absorber;
2. Strengthen the rigidity of the machine by replacing parts;
3. Cut the spring substantially and lower the suspension steeply.

Due to this upgrade, the car will gain additional stability and can be extremely grouped on turns.

Like all members of the large VAZ family, the “nine” has rear drum brakes. It makes sense to change them to disk ones.

Installing an automatic transmission on a VAZ 2114

— As practice shows, the best option for a VAZ 2114 car is an automatic transmission from a Toyota Camry car. Previously, the automatic transmission from Toyota Camry undergoes a major overhaul with the replacement of worn parts.

— Installing an automatic transmission on a VAZ 2114 begins with preparing the car for such a replacement. The air intake system is removed from the engine compartment, the front wheels are removed, the suspension and steering gear are disassembled, and the axle shafts are removed.

“Then it’s the engine’s turn. The engine is completely removed downwards from the engine compartment using a dolly.

— Preparing the engine for installation of a new box begins with removing the brackets that have become unnecessary for attaching the transmission to the body.

New brackets will be installed instead.

— We are starting to prepare other components of the car for the installation of an automatic transmission. It is necessary to install an additional radiator for the box cooling system.

— At this time, another mechanic is dismantling the manual transmission of the VAZ 2114 and preparing a place for docking the engine with the automatic transmission.

— Now it’s the turn of the clutch and flywheel. These details are no longer needed.

— Next, it is necessary to carry out an important operation to refine the angular velocity joints. The diameter of the axle shafts is reduced on a special machine. Without this work, joining the VAZ axle shafts to the new gearbox will be impossible.

— Now it’s the turn of the new flywheel, with this operation the process of installing a new gearbox on the old engine begins. Install a new box on the engine.

— The key operation is to attach the new box to the flange of the VAZ 2114 engine. It must fit exactly where the old box is attached.

— It is necessary to adjust the seats to the engine housing and gearbox for a tighter fixation of the brackets.

— Now install the box together with the engine in the engine compartment of the car.

— All that remains is to connect the electrical wiring harnesses of the transmission control unit to the vehicle’s on-board network. And also carry out a complex of installation work in the cabin.

The following video talks about installing automatic transmissions on VAZ cars.

If you need to move quickly and comfortably, it is recommended to use the services of a taxi in St. Petersburg. Qualified driver, reasonable prices and quality service. A nice fact is that you can order a taxi to the airport online.

The 5-speed manual transmission VAZ 2109 was produced at a plant in Tolyatti from 1987 to 2005 and was installed on all numerous front-wheel drive AvtoVAZ models on the 2108-09 platform. This transmission is designed for torque of power units up to 1.6 liters and 120 Nm.

The ninth family also includes 5-speed manual transmissions: 2113, 2114 and 2115.

Differential

It is located directly in the gearbox itself (for front-wheel drive vehicles). Manufacturers install it in order to improve handling and slightly reduce tire wear. However, if the car is operated in conditions close to racing, then the differential worsens handling rather than improves it.

That is why sports cars have a self-locking differential, the main parameter of which is the locking coefficient. The maximum value cannot be greater than 1 - in this case the wheels rotate at the same angular speeds and the wheels do not have a load difference.

However, in practice this is only required for SUVs, and even then not always. A standard road car has a differential ratio of up to 0.7. The value may be changed depending on operating conditions. If the coefficient is too high, then there is a possibility of demolishing the front axle when cornering.

Independently removing and blocking the differential can lead to the need to repair the VAZ 2109 gearbox, and incorrectly performed blocking will lead to noise and hum from the axle, which will still require replacement.

Types of box configuration

The configuration of gears can be different, depending on what you want to get as a result:

Tuning the VAZ 21099 suspension is a necessary necessity

Every driver knows that the condition of the suspension has a significant impact on the driving performance of the car. For example, a low-quality shock absorber will double the braking distance. That is why modernizing the suspension of the “ninety-nine” is a topic that will be useful to everyone.

The service life of standard shock absorber struts is very low, and if we take into account the quality of our roads, the situation becomes even more deplorable. Basic tuning involves replacing the factory telescopic hydraulic shock absorbers with two- or one-pipe gas-filled analogues

This achieves improved stability and controllability of the vehicle.

The stiffness of the new shock absorbers will slightly reduce the smoothness of the ride, but you shouldn’t get hung up on this, as you get much more benefits. When choosing new shock absorbers, you should look at the table of interchangeability of shock-absorbing devices. This will allow you to select equipment that fully corresponds to the overall installation dimensions and requirements of your machine.

Standard springs, working in conjunction with shock absorbers, have a number of their own shortcomings, which can only be eliminated by replacing them with new ones. Therefore, we install springs with a progressive action characteristic on the rear axle. This will improve the smoothness of the car and, as a result, overall driving comfort.

The car jerks when starting, it is impossible to shift into gear

The cause of the malfunction is not always the VAZ-2109 gearbox itself. Repairing it may not save it if the clutch assembly is faulty. But it is this system that interacts with the gearbox and engine. It is through the clutch disc that torque is transmitted from the flywheel to the transmission shaft. Typically, this unit serves at least 120 thousand kilometers. But many “nines” have old-style odometers, which reset to zero at 100 thousand.

It is difficult for the driver to control when this or that part in the clutch has been replaced. If the car jerks at start-up and the transmission is difficult to turn on, most likely the disc has been worn out. The plates wear out on it and the damper springs fly out. The petals on the clutch basket are also bent. We have already said about bearings that they are noisy. All this together affects the behavior of the car on the road.

Advanced tuning

The advanced column includes many modifications at once, among which are tuning the VAZ 2109 engine, replacing shock absorbers, brake pads, discs themselves, and visual modifications, such as replacing bumpers and painting.

It is important to understand that all this makes sense to do only if the car was initially in fairly good condition, and we are now talking to me about individual parts, but about the base - the body and its components

If the car has often spent the winter outside, the process of body rot may eventually begin, which, without proper attention, is the beginning of the end of the car.

That is why, before making any expensive modifications, it is worth doing a thorough inspection of the entire car.

The process of replacing the gearbox rocker

Dismantling the old rod

First you need to loosen the clamp on the main rod and remove the hinge from it. To do this, use a 13mm wrench. Next, remove the boot and, using a 10mm wrench, unscrew the bolt on the desired cardan. Usually it is fixed almost tightly, so here you will need a hammer to loosen it a little with gentle blows. By the way, you can immediately check the condition of the oil seal and, in case of any defects, replace it with a new one.

New drawstring and cord from Kalina

Installation of a modified backstage

Having removed the old cardan, you can begin installing the new one. To do this, you must first put on the boot. Next, we place a new cardan on the gear selector rod and secure it with a fixing bolt. Be sure to make sure that the bolt fits into the special recess on the rod. Also, do not forget to apply thread locker to the bot so that it does not unscrew due to vibration.

The next step is to put the drive rod on the rod. For some models, the stem from Kalina will have to be shortened by about 1.5 cm.

Adjustment

Next, you must carefully adjust the position of the lever so that it is centered with a slight offset to the right. Here we will need an assistant who will have to monitor the placement of the lever in the cabin. After installation is complete, tighten the clamp, while an assistant must hold the lever from moving.

And, of course, you yourself should try how conveniently the lever is adjusted and, if something happens, reconfigure it.

By the way, some craftsmen cope with shortening the scenes without buying a new one. To do this, you need to disassemble the slide, as in the previous paragraph, and trim the necessary parts using a grinder. Next, weld a piece of pipe and sheet metal into the rod. If you yourself are not very knowledgeable about this, you can ask any welder. This process can be studied more clearly using a visual video.
