Disconnect the wire terminal from the negative terminal battery. Then you need to remove the power unit mudguard (otherwise called “engine protection”), if you have one installed.

On each side of the engine protection, use a Phillips screwdriver to unscrew 2 screws securing the mudguards of the engine compartment to the mudguard. Then use a 10mm head to unscrew the 2 bolts rear mount protection (one on each side). Now, holding the engine protection, unscrew the 5 front mounting nuts with a “10” head. Remove protection.

Remove the right mudguard from the engine compartment. To do this, use a Phillips screwdriver to unscrew the screw securing the shield to the fender liner. Using a Torx T-30 wrench, unscrew the 2 screws securing the shield to the body. Remove the mudguard.

Drain the oil from the gearbox. It is better to do this operation on a warm gearbox. Place a container with a capacity of at least 3.5 liters under drainer and using a spanner wrench or a 17mm socket, unscrew the drain plug. After draining the oil, screw the plug back on.

Proceed to removing the air filter. Remove the wires coming from the engine management system to the sensor mass flow air. Then loosen the fastening clamp and remove the air supply hose to the mass air flow sensor from the pipe throttle assembly. Then disconnect the air intake hose from the fitting at the bottom of the air filter housing. If you have new rubber air filter supports, take a knife and cut off the old supports holding the filter in place. If there are no new supports, then carefully remove the supports from the mounting points (3 pieces).

The next step is to remove the starter. Using a “13” socket, unscrew the nut securing the tip of the starter wire connected to the “positive” terminal of the battery and remove the tip of the wire from the contact bolt. Then disconnect the control wire by hand traction relay(or retractor relay) and with a 15" socket, unscrew the two nuts securing the starter. Remove the starter.

Step-by-step instruction

Drivers who do not want to tinker with their car use the services of a service station. The procedure for removing the gearbox can be done by yourself. True, you will need an assistant to carry it out.

What will you need?

To carry out work on the gearbox, the vehicle must be driven to inspection hole, lift using a lift or install on an overpass. Before you begin the process of removing the gearbox from a VAZ 2109, you need to drain the oil from it.

To remove the gearbox you will need:

a set of keys;
mount;
for draining oil, a container with a volume of about 5 liters.

Stages

The procedure for removing the gearbox on a VAZ 2109 includes the following steps:

Before carrying out work, the car must be de-energized - disconnect the negative terminal on the battery.
Next, the protection from the engine crankcase is removed. To do this, unscrew the screws with which it is attached to the body.
The ground wire must be removed from the stud by unscrewing the bolt holding it.
Next, release the clutch cable by loosening the nuts on the tip of the clutch cable. And then remove it from the clutch lever.
The next step is to disconnect the block supplying the power wires from the starter.
Next, unscrew the nut and remove the power cable going to the battery from the stud.
To disconnect the starter from the clutch basket, unscrew three mounting nuts.
By carefully pulling the starter towards you, you need to remove it from under the hood.
To perform further work, you need to move under the car. The gear shift drive rod is disconnected from the joint tip by loosening the clamp.
Then the reverse sensor is disconnected.
After unscrewing the fastening nut, disconnect the cable from the speedometer drive.
The next stage is working with stretch marks. There is no need to remove them, just loosen the nuts securing them to the suspension arms.
Then, the bolts securing the bracket to the car body or the nut that secures the braces to the bracket are unscrewed; the braces need to be moved apart so that they do not interfere.
Next, the cotter pin of the nut is removed, with the help of which the ball is attached to the swing arm and the fastening nut of the ball is unscrewed.
Now use a puller to press out the finger ball joint from the swing arm of the strut.
Then the steering tips are disconnected from the steering cams.
At the next stage, using a small pry bar as a lever, you need to rest one of its ends against the drive hinge and push the grenade out of the box.
After removing the drive, you need to install a technical plug in its place; you can use an old grenade. Now you can start removing the second one. If you do not install the plug and start removing the second drive, the differential gears located inside the box may shift, which will then be difficult to install due to the fact that the grenade shanks will not be able to get into place.
Next, the mounting bolts are unscrewed and the shield is removed.
After this, you should loosen the screws and nut that hold the clutch housing and cylinder block together.
The next step is to fix the engine in a suspended state. This must be done, since when removing the VAZ 2109 gearbox, the mounting bolts of the power unit supports are unscrewed. To do this, a reliable wooden beam is installed on the front fenders, on which the engine will hang. Protective material should be placed on the wings first. paint coating, and place wooden support bars under the beam in the area of the front pillar supports.
Next, the engine is suspended using a strong rope or wire.
We suspend the engine. We unscrew the fasteners of the left support.
After unscrewing the nut, remove the left engine mount bolt.
Then unscrew the nuts securing the motor to the gearbox and remove the support.
Next, you need to finally unscrew all the fasteners on the other side of the gearbox. Then you should remove the box from the car by pulling it towards you. In this case, you need to act carefully so as not to break the clutch basket.

The DIY removal procedure is complete. Then you can continue repair work.

VAZ-2101 cars are equipped manual transmission 4-speed gears, the main part of the gearbox is located under the bottom of the car.

Basic faults

The gearbox used on the Kopeyka is structurally a fairly reliable unit, capable of handling a significant resource without any special intervention. But still there are problems with the gearbox.

The main problems with this unit are:

Increased operating noise. This happens mainly due to wear of bearings and gears. To restore functionality, it is necessary to replace all worn elements;
Difficulty changing gears. The reasons for this may be problems with the clutch, deformation of the gearshift lever or shift forks. Troubleshooting is carried out by replacing damaged clutch and gearbox elements;
Spontaneous transmission shutdown. This malfunction occurs due to wear of the clamps of the sliders of the power forks. The malfunction is eliminated by replacing the springs and the clamps themselves, sliders;
Oil leaking from the box. Leaks occur due to damage and severe wear of the box seals. Everything can be eliminated by replacing rubber elements;

Of course, there are other types of malfunctions, for example, jamming of the gearbox while driving, the inability to engage or disengage any gear, destruction of gears or shafts, and breakdown of the gearbox housing. But such problems arise much less frequently and are mainly due to improper operation of the gearbox, as well as design defects constituent elements boxes.
Elimination of any of the malfunctions is carried out on the removed box. Therefore, in order to restore the functionality of the gearbox, you must first know how to remove the gearbox on a VAZ-2101. Moreover, it doesn’t matter whether the VAZ-2101 gearbox is being repaired or replaced, it will still have to be removed.

What you need

This operation is not particularly complicated, but it requires certain skills and knowledge of the sequence of work. The complexity of the operation lies in the fact that many elements have to be unscrewed and disconnected, and access to them is not always convenient.

To remove the box you will need the following tools and accessories:

A set of keys and sockets (including keys for 10, 14, 17, 19);
Screwdrivers (thin flathead, Phillips, impact);
WD-40;
Line segment input shaft boxes;
Long wooden beam;
Rags;
Marker;
Container for draining transmission oil;

All work is carried out in three places - the interior, the engine compartment, and under the car. Therefore >a viewing hole will definitely be required.

Sequence of work

Having prepared everything you need, you can begin work.

The removal sequence is as follows:

We put the car in a pit and immobilize it wheel chocks installed under the wheels. We put the box in neutral position, do not tighten the handbrake;
First we will do all the work in the salon. At this point it is necessary to remove the lever from the box rod. To do this, pull the lever boot up, which will provide access to the fixing sleeve. You need to carefully pry it up with a thin screwdriver so that it pops out, after which you can pull the lever off the rod;
Remove the upper plastic sleeve from the rod by opening the petals with a screwdriver, then rubber boot and the lower bushing. As a result, there should be nothing left on the rod;
Remove the plastic trim located under the floor covering. To do this, you need to remove the seats, their guides, etc. from the car. It is much easier to make a cut to the side rear seats, this will allow the interior not to be disassembled. Having provided access to the cover, unscrew the 4 screws securing it and remove it. We turn on 1st gear at the gearbox;
Let's go under the car. For ease of work, it should be completely dismantled exhaust system. To do this, unscrew the muffler from exhaust pipe. To make it easier to unscrew bolts and nuts, you should treat them with WD-40 in advance;
Having removed the muffler, go to engine compartment, and unscrew the nuts securing the exhaust pipe to exhaust manifold. Then we remove this pipe from the car;
All subsequent work is carried out under the car. Unscrew cardan shaft from the gearbox flange. Next, unscrew the two safety crossbars to lower the cardan down;
Place the prepared container and unscrew drain plug to remove oil from the gearbox;
Unscrew the fastening of the clutch slave cylinder. In this case, there is no need to disconnect the pipe from it; after unscrewing the fastening, it should simply be moved to the side;
Unscrew the 4 bolts securing the clutch housing cover;
We support it with a beam back boxes and unscrew the nuts securing the cross member. Carefully pull out the beam. In this case, the rear of the gearbox will go down a little, this will provide more convenient access to the remaining elements that need to be removed;
We disconnect the chip with the wiring suitable for the gearbox. Unscrew and remove the clutch cable;
We get to the bottom and unscrew the starter mounting bolts. Start with the top bolt. After unscrewing the fastening, move the starter away;
We place a support under the rear part of the engine, after lifting the box by hand;
We unscrew the bolts securing the gearbox to the power plant;
Supporting it with your hands, rock it up and down to remove it from the guides, and then remove the input shaft from the clutch and lower the box down;
We install the prepared section of the input shaft into the clutch to prevent displacement of the driven shaft.

Reinstalling the box is carried out in the reverse order. In this case, you should check the installation of all removed elements in place, as well as the reliability of tightening the fasteners.

In what cases should the gearbox be removed?

Before removing the gearbox, you should make sure that the faults are related to it and are not caused by, for example, insufficient level oil, loose gearbox mounts, defects in the clutch release drive.

The need to remove the gearbox occurs when the following malfunctions occur:

transmissions switch off spontaneously;
unclear gear shifting;
increased noise, appearance of extraneous sounds;
when overtaking, the clutch disappears;
gears are difficult to shift;
oil leaks.

In addition, the gearbox should be removed in the following cases:

when replacing the clutch;
when replacing old box transmission to a new one;
if necessary eliminate;
when replacing front oil seal checkpoint;
when replacing the release bearing;
when replacing the flywheel;
when replacing the bushing;
in cases where the box interferes with any repair work.

The weight of the box without oil is approximately 30 kg, so it is recommended to carry out the procedure for removing it with an assistant. It is advisable that he has experience in auto repair work.

Instructions for removing the gearbox

The procedure for removing the gearbox is labor-intensive and time-consuming. It’s easier to replace it with a VAZ 2110 by visiting a car service center, but you can do it yourself.

Tools

To carry out the procedure, you will need tools consisting of:

a set of wrenches, socket or open-end wrenches;
set of heads with extensions;
flat screwdriver;
mounts;
pliers;
jack;
clean rags.

In addition, you should prepare a container to drain the used oil. You can use a plastic 5 liter bottle.

Tools should be prepared in advance so that they are nearby while working.

Sequencing

To remove the gearbox, you need access to the underbody of the car, so it needs to be lifted. This can be done using a lift, or driving the car onto an overpass or inspection groove.

Since the removal work is quite complicated, you will need an assistant.

IN next video The replacement of the clutch is demonstrated, the first step of which is removing the gearbox.

Removing the gearbox from a VAZ 2110 car consists of a sequence of steps:

First, you should remove the engine mudguard (protection). To do this, use a socket wrench to unscrew the mudguard mounting bolts and remove the protection.
Next, we dismantle the engine compartment shield on the right.
The next step is to drain the oil from the gearbox. To ensure proper drainage of the oil, it is recommended to warm up the engine before draining, allowing it to run for several minutes. Next, place a prepared bottle or other container under the drain hole and unscrew the drain plug.
When the oil has completely drained, clean the plug and hole from dirt. Then screw the plug back.
After draining the oil, you need to turn off the power to the car by disconnecting the negative terminal from the battery.
Next you need to dismantle air filter: the hoses of the crankcase ventilation system, air supply and air flow sensor are disconnected. The air filter housing is removed along with throttle valve, sensor and hose.
Then you need to remove the starter from the car. First you need to unscrew the nut that secures the tip of the clutch wire connecting the starter to the positive terminal of the battery. Next, you need to remove the tip from the contact bolt. Now you need to disconnect the traction relay control wire, unscrew the fastening nuts and remove the starter.
At the next stage, we disconnect the clutch drive cable from the gearbox bracket and the gear shift fork. To do this, you need to pull the clutch cable out of the fork lever in the engine compartment. Then you should loosen the fastening nut of the cable sheath to the bracket on the gearbox. While holding the sheath, you can pull the cable end out of the bracket.
Now you need to disconnect the wire connector from the speed sensor, as well as from the reverse sensor.
Next we disconnect jet thrust. It is attached to the buffer using two nuts. After unscrewing the nuts, remove the bracket. Now the rod can be dismantled.
Now we disconnect the gear shift rod from the hinge.
Then we tighten the fastening bolts on the clutch housing cover and remove the cover.
Now we remove the wheel drives. A wooden plug should be installed on one drive to avoid any problems during installation.
Then we remove the right drive, but you can simply move it to the side and not remove it.
To simplify the removal procedure, you need to loosen the ball joint bolts.
After unscrewing the mounting bolts, you need to remove the lower crankcase cover.
Then you need to unscrew the lower bolt securing the gearbox to the engine.
Next we post power unit using the prepared stop. You can use a board as a support. After unscrewing the fastening nut, remove the left engine mount.
Having unscrewed the nuts that secure the rear engine support to the body, and the bolts securing it to the gearbox, holding the nuts from turning, we dismantle the rear support.
To move the box from the guide bushings, you need to insert a screwdriver between the cylinder block and the clutch housing. When moving the box, it should be held so that it does not rest on the diaphragm spring crankshaft. Due to significant load, the spring may become deformed, which will lead to malfunction of the unit.
While rocking the gearbox, we move it as far back as possible and dismantle it.
