Removing the gearbox from a VAZ 2113, VAZ 2114, VAZ 2115

How to remove the gearbox from a VAZ 2113, VAZ 2114, VAZ 2115?
This question may arise in a number of cases, whether it is replacing a clutch disc , clutch basket , release bearing , or replacing a flywheel crown. And there are many other reasons for the need to remove the gearbox. In this regard, this procedure is included in a separate article. Removing the gearbox is a thorough process and you need to prepare for it properly. You will need: a lift or pit, a set of socket wrenches (sizes: 30, 19, 17, 13, 10), a flat-head screwdriver, a mount…………..
After preparing all of the above, you can proceed directly to removing the gearbox. First of all, remove the terminal from the battery. The air filter will interfere with us, so use a 10mm wrench to unscrew the air filter mount. We disconnect the mass air flow sensor and move the filter to the side, along with the pipe.

It would be enough. Using keys 13 and 17, disconnect the power supply to the starter and unscrew one bolt (indicated by the upper right arrow (the rest will be more convenient to turn from below) securing the starter itself.

Unscrew the two nuts securing the gearbox to the engine. Use a 17 key to disconnect the clutch cable.

Next, we hang up the car and take off the front wheels. Use a 30mm wrench to unscrew the hub nut, having previously loosened it.

At the same time, it is necessary to keep the brake pedal depressed. And not weakly, because as a rule the hub nuts are tightly tightened. Further actions will take place under the car. The next step is to remove all the protection available under the engine compartment.

If you need to remove the drive, in order to protect against possible leaks, you need to drain the oil, for which you unscrew the bolt-plug with a 17mm wrench. Here we will consider the option without removing the drives from the gearbox. After the engine protection is removed, you need to use a 17mm wrench to unscrew the three bolts securing the crabs.

Using the key again at 17, unscrew the stabilizer mounts.

Using the same key, unscrew the two bolts securing the ball joints.

After carrying out these procedures, you can pull out the drive. To do this, it is necessary to remove the drive from the hubs on each side by simply moving the hub to the side.

Disconnect the reverse switch. Disconnect the speedometer terminal.

Now we remove the starter by unscrewing the remaining two bolts (let me remind you that one bolt on top has already been unscrewed) securing it.

From the rear, on the interior side, a rod approaches the gearbox (the rod comes from the gear shift lever). This rod will be connected to the gearbox rod through a clamp tightened with a bolt and nut size 13. We loosen this clamp and pull the rod off the splines of the rod.

So, using a 10mm wrench, unscrew the three bolts securing the flywheel protection, the so-called crescent.

Unscrew the side airbag fastening. And the rear cushion is attached to two studs. And finally, we unscrew the remaining two bolts (the first bolts, let me remind you, we unscrewed them from the top) securing the gearbox to the engine. After the work has been done, the gearbox can be removed, first by hooking it with a pry bar.

The box must be removed carefully, especially without damaging the petals on the clutch basket with the input shaft. The box has been removed. Its installation is carried out in the reverse order of removal. When the process as a whole is clear, the sequence of some steps can be changed, depending on what is convenient for you. In addition, it should be noted that after installing the box in place, it will be necessary to adjust the travel of the clutch pedal by moving the clutch cable to a certain position using the corresponding nuts.

How to remove the gearbox?

The VAZ 2114 and other models of the LADA SAMARA family range are equipped with a five-speed gearbox combined with a differential and final drive. In principle, the box from the VAZ 2114 is no different from the VAZ 2108. The only thing is that the VAZ 2108 does not have a dipstick, and acceleration on it will be faster.

You will need to remove the box to replace the clutch, clutch bearings, and repair the box.

How to remove the gearbox?

To remove the gearbox we will need:

First of all, remove the terminals from the battery and take it out. We drain the oil from the gearbox (How to drain the oil from a gearbox?) and remove the starter (How to remove the starter on a VAZ 2114?). As you work, if you can’t unscrew any fastening or bolt, then don’t forget to use wd-40.

1. Place the car on the overpass (pit) and remove the crankcase protection by unscrewing 3 fasteners.

2. Next we need to remove the clutch cable from the clutch release fork. Then we pull it out of the bracket on the box.

For the purpose of complete understanding for the reader, the slides refer to points 3-19 in order except point 14, where you need to hang the engine.

VoFFsK › Blog › Replacing the clutch of a VAZ 2115 without a pit and a lift.

Good day to all! I’ll tell you about how I changed the clutch on my 15x. I’ve been driving with a dead clutch for about half a year. I’m pretty fed up with the fact that at 3rd speed, if you go to overtake, the car doesn’t listen. starts to accelerate. However, if you accelerate smoothly, 130 goes easily. Closer to the point: Repaired in the village, 2000 rubles. The toad made me give it to the guys at the service center. I changed everything at once, it’s calmer! )) I have an article about the release lever, and KraftTech bought the clutch for 3000 wooden ones. The release lever was included in the kit, but it didn’t inspire confidence. That’s why someone else installed it. I parked the car on level ground, with the handbrake on. I secured it with bricks under the rear wheels. INSTRUCTIONS: Ask your friends about the alignment or input shaft of the gearbox, you can even center the clutch disc from the “classics”. It’s better to do the work in 2m, especially after you throw off the box. I’ve already seen someone like this. Unscrew the hub nut (head 30, knob and pipe). There's a puck there, don't lose it! Let's jack it up. We unscrew the left wheel and remove it. We unscrew the ball joint (part 13). On the right side we unscrew only the hub nut, but not completely. We remove the engine protection, if there is also the left side of the engine boot (k-ch8). We remove the air filter, the battery. We jack up the car higher, put hemp, bricks or SCC blocks under the side members or sills, whichever is given what. I had these blocks. By 2 On each side. This height is enough to completely move under the car. Place a beam or piece of wood on a block or brick so as not to crush the box. We take a jack and a beam, jack up the engine. (This is how it should be!) Lay out an old blanket, climb under the car. Unscrew the rocker clamp (key 13), the gearbox cushion (17). There is also a stretcher from the engine, we also unscrew it. The key is 19. It took us a ton of effort, because it was apparently tightened with great force and without the right drive, but it will interfere. There is also a box boot, from the end of the pallet. There are 3 bolts per 10. Found it? Removed it? Let's continue. We disconnect the speed sensor on the top of the box and another one on the left. We unscrew the clutch cable with a key of 17. We remove it from the fork. We move it to the side. We unscrew the bracket for the front box cushion, on the left. There are 3 nuts. Remove the starter, wire + and red (3 nuts k-ch13). The left drive pulls out of the hub. We unscrew (k-ch13) the fastening of the ignition coil from the box. I removed the coil, for convenience. And one by one we twist the remaining bolts of the box itself, there are only 4, with a 19 head. Next, with an assistant, one from the side of the arch towards you, one from above using a mounting tool or a powerful Use a flat screwdriver to disconnect the box from the engine. It should hang on the drives. You can completely remove the gearbox because The clutch disc will still need to be centered. If you are working on asphalt, place boards and a rag so as not to damage the gearbox. When the box was detached, it hung on the drives and the left tripwire from the crab. To access the basket, pull the box and secure it with an assistant) or something. We see the basket (there are different bolts). Mine was 8. I twisted it with a cap and licked off the heads of 3. I unscrewed it with a hammer, a mat and a chisel. Then I replaced it with an M8 13x15 bolt. We take out the clutch. There should be no sagging petals on the basket, and there should be no severe abrasion in the center from the release bearing. The pressure part should not have chips, scratches, grooves and signs of overheating in the form of a purple-dark blue color. If there is one of these signs, the basket better for replacement. We look at the disk itself. It is very worn if the rivets have already begun to shine on the surface, as was the case with me, or there are no springs. Next, we check the release bearing. It is installed on the input shaft and is held by a spring. You need to bend the whiskers towards yourself and remove it. Check for torsion and play. Let’s not allow too much play in the bearing on the housing. Play in the bearing race is unacceptable! If it is not possible to replace it with a new one, put lithol-type lubricant in it, but do not overdo it. It is better to remove the excess. We put the release lever back. Check the clutch fork boot! Next, we install the disk with the basket, lean everything against the flywheel, place it on the guides and insert the centering device. We attach the basket. It is advisable to tighten it crosswise, but not critically. We screw it to the flywheel with force. Next, with an assistant, we lift the box and guide it, be careful, the gearbox is quite weighty. If the shaft does not immediately fit into the splines, turn the box a little. When the shaft is in, insert the box all the way and tighten the top bolt.

Determining the malfunction and how to fix it

There can be many reasons for the malfunction, but the main ones can be identified independently. You can find out what happened to the box by the following factors:

The reason for the constant noise while driving may be wear of the gears or failure of the bearings. The problem is solved by replacing them. But before the box is removed for further repairs, make sure there is oil. There are times when it just needs to be topped up or replaced.

Inadvertently shifting gears while driving can cause wear on the synchronizer teeth or severe vibration due to damaged rear bearings. Damaged support seals and synchronizers can always be replaced with new ones.

The reason for the gear not engaging may be the following:

A cracking noise when turned on can be caused by an unpressed clutch and a broken synchronizer ring of the VAZ 2115. If a leak is detected, it must be repaired immediately. Typically, oil begins to leak from the drain plug or from a crankcase mount weakened by constant vibration.

You will need the following tools and accessories:

1. Clutch kit. disc, output bearing, basket, bolts. Be sure to change the driven disk. The leader (basket) changes less frequently and has a much larger resource.
2. Set of wrenches, winding keys, sockets.

5. Two nests are better. When removing a drawer, place a second drawer under the tray to keep it level and prevent it from falling.
6. Car mounts and wheel covers.
7. The presence of an overpass, pit or lift is welcome.

How is the box constructed?

All VAZ 2115 cars are equipped with a five-speed manual gearbox, which is paired with a differential. The input shaft consists of a set of 1st-4th gear drive gears and one removable 5th gear gear. All of them are connected to drive gears, which are located on the secondary shaft. They are intended for forward gears only.

Gearbox for VAZ 21115

The control device includes: a shift lever, a ball joint, a set of rods, a mechanism for selecting the gear to be switched for a VAZ 2115 car. This is a separate mechanism located on the clutch housing. Two axles for switching are built into the housing and are connected to a three-arm lever.

Removal and Installation Guide

To conveniently dismantle the box from the car, you need to use a lift or inspection pit. It is extremely inconvenient to carry out work on a flat surface.

Having fixed the VAZ 2115 on the lift, you need to open the hood, remove the terminal from the battery and starter, disconnect the ground and the clutch cable. Next, having unscrewed the clutch and starter mounting bolts, we fix the exhaust manifold of the VAZ 2115 engine with a lifting mechanism bracket.

After installing the engine support safety crossbar, we move on to the bottom of the car. We remove the protection, then dismantle the clutch housing after draining all the oil. We disconnect the reverse sensor, loosen the clamps and remove the rod from the rod joint intended for changing gears. We unscrew the stud mounting the VAZ 2115 engine with the gearbox.

Then we disconnect the steering knuckles from the ball knuckles and carefully remove the axle gear to avoid it getting into the crankcase. Having completed this operation, we knock out the second hinge, while moving the wheels in different directions. If it is not possible to disconnect the wheel drive from the axle shafts, the box is removed as an assembly. Using special equipment, press the hinge out of the axle gear.

When you have everything in a suspended state, unscrew the remaining mounting bolts, having first positioned the hydraulic lift. Lower the engine slightly on the safety cross member and the gearbox will easily come down.

Removing the primary and secondary shafts

It is better to leave it to a specialist to disassemble the box itself and replace worn gears. If you have never done this before, it is better to refrain from experimenting. It is not difficult to disassemble it, but not everyone can assemble it without certain skills. Even experts sometimes make mistakes because of which they have to disassemble everything again.

When the box is repaired, do not forget to fill in special gear oil before installing it on the car. It is much more convenient to pour it on the ground. Oil must be filled strictly according to the level. High-quality oil will ensure uninterrupted operation of the box, while extending its service life for many years.

Installation occurs in complete reverse order. The main thing is not to forget to replace all the old retaining rings and before starting installation, lubricate the outer surface of the clutch sleeve of the bearing that disengages the clutch. After the installation is completed, all that remains is to adjust the clutch pedal travel and the drive that controls the gear shift mechanism.

Always change gears smoothly, fill in high-quality oil and your gearbox will serve trouble-free for many years.

Do-it-yourself repair of VAZ 2108-099, 2110-2112, 2113-2115 gearboxes for the first time (brief instructions)

Problems with the gearbox began last summer, the 2nd speed was difficult to engage, in the spring the gear selector rod seal leaked, then the 3rd speed finally began to crunch when turned on. But the real juice was when you urgently need to go somewhere, and the reverse speed is not ALE!, and when you can go slowly, then with the reverse - everything is fine! Since I do the repairs myself, I decided to do everything myself this time (in the sense of not contacting service stations and other garage technicians), it’s not all that difficult))) We remove and disassemble the box (there are plenty of video instructions on the Internet)

If you take it apart, you need to change all the consumables at once, so you don’t have to go through it again later.

We press out all the bearings and seals from the gearbox housings, remove the satellites, disassemble the secondary shaft, in short, throw everything into the trash. We carry out troubleshooting and find the reasons why our gearbox did not want to work properly. We take old spare parts with us as an example, because VAZs also had parts of different sizes. Don’t forget to take a friend with you and let’s go with him for new parts. We buy everything we need and don’t need, spend all the money we had in our pocket, borrow money from a friend and spend it too. Satisfied, we go to the garage.

Before disassembling the gearbox, I watched several videos. Everything is easy and simple, I took it apart, changed it, installed it and went. BUT, there was a small problem during assembly! It turned out that everything was not entirely simple.

So, if the bearings are good, then it’s better not to touch them, since I started looking all over Kharkov for these rings, not every store has them, and if they do, then, as always, they don’t have the required thickness!

A small manual from the encyclopedia for assembling the gearbox:

1. When assembling the gear selector lever and the joint with the gear selector rod, first degrease the threaded holes in the joint body and the lever hub, as well as the mounting mounting bolts. 2. Apply thread sealant to the bolt threads. 3. We press the oil seals of the input shaft, drives and gear selection rod using mandrels or suitable pipe sections. 4. Lubricate the working surface of the oil seals with a thin layer of Litol-24 lubricant. 5. We install an oil seal with a right notch in the clutch housing (for right-hand drive), and an oil seal with a left notch in the gearbox housing (for left-hand drive). The arrows on the oil seal housings must coincide with the direction of rotation of the drives when the vehicle moves forward. 6. When assembling the secondary shaft, we replace the retaining rings of the synchronizer hubs with new ones. We press the outer and inner rings of roller bearings, ball bearings, gears and synchronizer hubs with mandrels or suitable pipe sections. 7. When assembling the hub with the synchronizer sliding clutch, before installing the retainer, apply a little grease to it and put it in the cracker. 8. Using a screwdriver, press the installed synchronizer spring towards the hub and put the block with the lock in place. In this case, the deepest socket should be located opposite the latch in the sliding coupling. 9. When assembling the differential, lubricate the satellites and drive gears with oil. 10. We mount the differential bearings with a preload of 0.25 mm. The tension is ensured by selecting the thickness of the adjusting ring installed in the gearbox housing socket under the outer ring of the differential bearing. 11. Selecting the thickness of the adjusting ring is necessary if replacing one of the following parts: differential box, differential bearing, clutch housing and/or gearbox housing. 12. After installing the differential into the clutch housing, it is necessary to secure one of the drive gears with a mandrel (plug) so that they do not move from their seats during further assembly. 13. Before assembling the gearbox housing with the clutch housing and the rear cover, apply a layer of sealant around the perimeter of the mating surfaces.

Is it true that the box from the VAZ 2115 fits in the VAZ 2109?

Even the best cars sometimes break down, and our beloved “nines” are not immune from this.

A breakdown of the gearbox especially hurts the pocket of a car enthusiast, because a good option for replacing it costs far from a penny. But sometimes it happens that there is money, but there is no good replacement.

There is an opinion that a gearbox from Samara could be a good option for replacing a broken part from a 9, but is this true?

Difference in characteristics

Sometimes it happens that the required part is not on sale, or the quality of those presented does not satisfy the driver’s needs. In the case of replacing a gearbox, you can often hear that VAZ gearboxes are completely interchangeable, you just need to change a few parts, and that’s it – you can install it.

But will the box from 2115 to 2109 actually fit? Before answering this question, you need to compare the characteristics of these boxes. The first thing that catches your eye when considering this option is the difference in torque, namely 120 versus 125, and the amount of lubricant - 3.5 versus 3.4.

Both indicators are higher in Samara, but it seems not critical. Another important aspect is the gear ratios, here you can also see a small difference, especially noticeable when considering the final drive: 3.937 on the nine and 3.7 on the Samara.

In general, the difference when driving is unlikely to be noticeable, even at low speeds.

Disassembling the VAZ 2115 gearbox

Wash the gearbox, preventing water from entering the crankcase, and place it on a disassembly stand. Remove the power unit suspension bracket and the clutch release cable mounting bracket.

Remove the primary and secondary shafts at the same time (

Unscrew the gear selector mounting bolts (

If it is necessary to disassemble the secondary shaft, clamp it in a vice with soft pads and use a universal puller to press the ball bearing from the shaft. The bearing is pressed off the input shaft in the same way. Then remove the driven gears of IV, III, II and I gears and synchronizers assemblies from the secondary shaft in the order indicated on

– if it is necessary to replace the driven gear, unscrew the bolts securing it and compress gear 7 (

If necessary, disassemble the gear selection mechanism by unscrewing the nut securing axle 6 (Fig. 3.16) of the gear selection lever and remove the retaining rings from the reverse fork axle and from the axle 7 of the locking brackets, remove the reverse fork 8, gear selection lever 4 assembly with a locking bracket 5, a lever axis 6 and a spring 11 with a thrust washer 10.

If necessary, remove the speedometer drive by unscrewing the nut securing it and, supporting the driven gear shaft, remove the speedometer drive.
