How to remove and install the flywheel. Its defective. Recommendations for the replacement of the flywheel How to put a new flywheel on the VAZ 2107

Engine flywheel internal combustion Used to accumulate energy. It helps the pistons to pass the bottom dead points (especially when starting the engine). The flywheel transmits the engine torque on the checkpoint. There are three types of flywheels:

• normal;
• lightweight;
• dampfer (in the damper inside the springs are installed).

The resource of the flywheel is usually 120-150 thousand km. It all depends on how intensively and in which modes the engine worked. Typically, the installation of the new flywheel is performed after the wear of the two sets of clutch friction linings, so the flywheel is validated with the clutch.

Repair of Makhovika

Frajects flywheel are obvious. This item is experiencing constant dynamic loads and friction, which leads to physical erasing of contact surfaces. As a result, vibrations or beats appear, the clutch can "slip". Simple flywheels are subject to replacement, damper is restored in special workshops.

One more typical malfunction It is damage or wear of the seashest. If the flywheel is still working, the crown change, if not, change the entire knot entirely.

With the repair of damper flywheels is more difficult. They are repaired and restored in specialized workshops. Defecting, accurate measurements, balancing machines, professional welder services will be required. The essence of the process is that the worn surfaces are grouped, the springs and the sliding bearing are changing. Flywheel balancing and experienced under load. After repairing the plane of the flywheel must "fall" into the admission of backlash and beats.

Replacing flywheel

For replacement, car shift, a transmission rack and standard instruments for fitter work will be required.

Replacing flywheel VAZ 2106

Engine classic Zhiguli. It has an ordinary single-mask flywheel. Consider how to remove the flywheel and the technological sequence of its replacement:

1. First you need to access the flywheel. If the engine is removed, there will be no problems if not - you need to dismiss the gearbox and the clutch basket;
2. Next you need to keep the flywheel from turning. For this, a special retainer is used, but a conventional screwdriver is suitable;
3. After removing the checkpoint, you need to unscrew six fasteners bolts, then we remove the flywheel;
4. Installation of new flywheel . Mounting the flywheel to perform in the sequence, reverse dismantling. Flywheel bolts are dragged to a cross on a cross with an effort 60.1-87.4 N.M.

Remove flywheel

The flywheel from the car VAZ 2106 is removed for replacement or repair during damage to the gear or with damage or strong wear of the friction surface.

The flywheel is installed at the rear end of the crankshaft and is fixed on it with six bolts: 1 - toothed crown; 2 - fastening bolt; A - Friction surface.
You will need: a screwdriver, a 1-on-17, dynamometer key.
1. Remove from the car VAZ 2106 gearbox (see section 5 "Transmission of the car VAZ 2106").

2. Remove the clutch cover from the flywheel with the pressure disc and the clutch disc (see section 5 "Car VAZ 2106 Transmission").
3. Screw the bolt into the left lower threaded hole of the clutch crankcase, lock the flywheel from turning, supervised the screwdriver into the gear and the openers of it on the installed bolt and the power steering, and unscrew the six flywheel fastening bolts.

4. Remove the support washer, holding the flywheel.
5. Remove the flywheel.
6. Check the condition of the gear crown; In case of damage to the teeth, replace the flywheel.
7. The surface of the flywheel, marked with the crankshaft and the slave disc clutch, should be without scratches, scales and completely flat. If on the working surface of the 3 flywheel under the slave clutch disc, there are scratches, crush this surface, removing the metal layer with a thickness of no more than 1 mm. Then crush the surface 2, withstanding the size (0.5 + 0.1) mm and providing parallelism of surfaces 2 and 3 relative to the surface 1. The tolerance of non-parallelism is 0.1 mm. After the groove, install the flywheel on the mandrel, centering it on the planting hole with a stop on the surface 1, check the beating of the planes 3 and 2. At least the indicator should not show the beats exceeding 0.1 mm.

8. Install the VAZ 2106 flywheel on the car and removed nodes and parts in order to remove. The flywheel can be set to the crankshaft in two opposite positions determined by the location of the mounting holes. However, at the factory, it is balanced assembly with the crankshaft, so it must be installed strictly in the original position. For proper installation on the flywheel made a label but In the form of a conical well, which must be oriented when installed in the same direction as the rod cervix fourth (first) cylinder. If, after removing the handwheel, the crankshaft was turned, install the fourth cylinder piston to the compression tact position (see "Installing the piston of the fourth cylinder to the NMT position of the compression tact"). and install the flywheel on the crankshaft by turning it with the label but vertically up. Fasteners fastening bolts Tighten a uniform cross-cross-time torque given in Appendix 1. "Tightening moments threaded connections VAZ 2106 "

Detailed procedure for removal by car VAZ 2110 flywheel, its defective (defect defects and their elimination if possible) and return installation.

Removal and defective flywheel:

1. Before starting work, remove the AKB (see article) from the car, drain the oil from the gearbox and remove.

2. Clean the gearbox and disassembly.

4. Holding the flywheel with one hand, - another remove the stopper plate of the bolts with the final bolt.

8. Also, a similar defect to spend on the back side of the slave disk, or rather, look at the adjacent often - the flange of the crankshaft.

If in 7 or 8 points there are similar distortion, then the flywheel must be replaced with new or repair - to stalind special equipment in the car repair shop.

• Defecting the adjacent surface of the clutch disk (3) should not be greater than 0.06 mm.
• Not a parallelness of the upper surface of the adjacent disk and the bottom (2) for the adhesion is not more than 0.1 mm.
• On the clutch disk planes (1 and 3), the beating should not be greater than 0.1 mm.
• When cleaning the surface of the flywheel (3) from abrasion and rice, you should know that the metal layer is not more than 1 mm.
• Simultaneously with the side (3), the surface should be stuck (2). To do this, expect a stage with a height of 0.5 ± 0.1 mm. With a fighting, observe the parallelism of the surrounding surfaces (1 and 3).

It is very important to correctly put the flywheel, otherwise it is not possible to avoid problems in the future. There is a specific scheme that should be done, but there is also its own nuances. Let's try to figure it out in more detail.

The general concept of flywheel

The part of the automotor, which is designed to regulate the supply of energy, is called a flywheel. It is due to this node that energy is ensured with a greater supply of rotational motion.

So, the flywheel in modern car Need to:

• wHOB;
• connect the engine with the checkpoint and transfer km from the motor to the checkpoint;
• adjust the rotation of the crankshaft.

Presenting a rather big metal disk with a mounted on the edge of a crown, the flywheel is easy to engage with the starter, after turning the ignition key. Thus, the engine is launched.

Flywheel Defect, Removal

The problems of the car begin, as a rule, after a significant run. In particular, the work of the clutch deteriorates. The flywheel itself can stretch to 200-300 thousandth mileage, but it happens that it flies much earlier. In this case, it is necessary to seek the causes of the ambulance associated, most likely with climate, clutch faults, etc.

It is clear that if the car's adhesion fails, it affects the flywheel.

The algorithm for holding a dismantling of the flywheel from the car is as follows:

• initially, the battery is removed, the oil is cleared of the PPC, the starter is dismantled;
• then the gearbox and coupling are removed;
• after that, bolts fixing the flywheel are unscrewed.

Council. When unscrewing the flywheel bolts, the latter can be turned. To stall it, you have to insert a screwdriver between the teeth of the flywheel or mont.

• the flywheel sticks with one hand, and the other - the last bolt-lock is removed together with the lock washer under the bolts;
• it's time to carefully remove the flywheel from the crankshaft.

Now that the flywheel is removed, you can explore it, or, as it is customary, to have a defect. The first thing is inspected by the teeth of the crown, which accepted over time, and when initially not proper installation - They come into disrepair at all, mixing the flywheel to engage with the starter.

You do not have to think in this case - if there are clear damage and flaws on the crown, the flywheel needs to be updated or renovated. It may be so that everything is in order with the teeth, but the frictional lining mirror has strong damage and other faults.

Attention. The repair of the flywheel will imply a replacement of the crown.

Reverse installation of the flywheel implies primarily degreasing bolts and threaded holes for them. Then the sealant is applied to the thread, the part is mounted back in the same order, as shown. But it is important to be able to combine the holes at the end of the crankshaft and flywheel (they must be asymmetrically).

Nuances of proper installation

The correct installation of the flywheel implies, above all, the coincidence of tags. If, when removing the flywheel, the position of the node relative to the crankshaft and the sensor was noted (it is just between), it leads to a problem.

Experts claim that the 20th tooth after breaking the flywheel, calculated up clockwise, should look at the crankshaft sensor, and the shaft itself is to stand in the VMT.

Attention. Check the position of the crankshaft can be on the reverse side of the engine. There is a special pointer.

In addition, knowledge of how to correctly install the flywheel will help fully implement the possibilities of the automotor. At the plant initially equip the system with a regular node. For example, on the VAZ - the knot is worth the old format, from the era of the Fiatovsky prototype.

Naturally, it served as a reason for modernization and alterations. And today, innovative techniques come to the help of Tuner.

Consider these opportunities.

Installation of a 2-mass flywheel makes it possible to move RSC (mesomery of oscillations) to the amplitude of rotation double smaller than idling DVS. In a 2-mass flywheel, the spring system is not in the clutch, but between cast-iron items.

Despite such a large number of positive properties, a 2-mass flywheel rarely becomes the choice of tuners, as it is expensive, it is not subject to garage repair from the high-performance manufacturer and for a number of other reasons.

Attention. Among other things, a 2-mass flywheel often fails. For launch of DVS. Or the motor stop is heard by the characteristic creak, noise and vibration, which indicates problems with the node.

More in an effective way Reduce the load on the checkpoint will be the installation of a lightweight model of the flywheel. In this case, the real weight of the product is reduced by the maximum possible value. The new node in the end weighs 4-5 kg \u200b\u200bless than the regular option.

Installing the lightweight model of the node implies a lot of nuances. First of all, it concerns the flywheel in both sides.

Summary: If for any reason the position of the shafts and flywheel causes doubt, it is recommended to do the following. Stop the label on the crankshaft in line with the risk on the bottom cover of the timing belt. At the same time, a label is exhibited on the flywheel, which should look at the crankshaft sensor. As for the camshaft mark, it must be at the level of the edge of the GBC.

When an extraneous noise occurs when the engine is often required to replace the flywheel. This procedure should be carried out in compliance with a number of recommendations.

Replacing the flywheel in the car may be required for a number of reasons, for example:

• in running;
• after a frequent change of clutch components;
• as wearing.

In this case, you can notice some signs of the malfunction of this part, for example, extraneous sounds when starting and stopped the engine. If such signs appeared, it is necessary to diagnose, repair or replace faulty elements, the device you want to know to correct faults.

In order to deal with the replacement procedure, you should study problem situationswhich may occur during the operation of the flywheel.

You can select multiple types of faults that occur when it is functioning this engine element.

First defect: wear and / or damage to the element gear

Causes of fault:

• wearing and / or breakdown of the starter, its individual elements or nodes;
• incorrect installation of the starter in the flywheel card;
• ingress of foreign particles in such a device like a flywheel carder;
• errors during construction assembly;
• the gear of the flywheel is worn during the long-term operation of the engine.

Progress:

• the flywheel gears must be replaced;
• the correct installation of the starter in the flywheel card;
• checking the starter work and its repair, if necessary.

Defect Two: Flywheat Battle

Causes of fault:

• clutch slip;
• natural wear of the component with long-term operation of the engine;
• build errors.

Progress:

• checking;
• with a small beyon - processing of surfaces by means of a lathe;
• with a large biogen - change parts;
• checking the functionality of the clutch, its repair and shift if necessary;
• checking the operation of the clutch shutdown and its repair, if needed;
• exercise proper delay Fastening bolts, and it is necessary to observe the right moment - approximately 100 N * m.

It is worth noting that the allowable value of the beyon must be installed by the manufacturer, it can be found in the appropriate directory. At the same time, you need to know what role the excess of this magnitude can play.

The beating can provoke damage to the working surfaces by which the slave clutch disc is functioning.

At the same time, the car owner may notice some signs of malfunction when the engine is running. When correcting malfunctions, it is necessary to observe the correct torque of tightening the fastening bolts.

Defect Third: Violation of the functionality of the working surface under the slave clutch disc

Causes of fault:

• wearing or breakdown;
• clutch slip;
• the device is worn at long-term operation of the engine;
• errors when assembling the part.

Progress:

• replacement of the element;
• check, repair and change of clutch if necessary;
• check and repair clutch shutdown as needed.

It is worth noting that the functioning of the element with a broken clutch can lead to the warming of the working surfaces of the flywheel, as well as to the formation of cracks.

These signs can be found during diagnostics.

Fourth defect: damage to the landing place under the flange of the crankshaft

Causes of malfunction

• the device is worn with long engine operation;
• detail assembly violation.

Progress:

• replacement details;
• checking, repair and replacement for the needs of the crankshaft;
• the correct setting of the crankshaft in the flywheel carter;
• proper assembly technology;
• implementing the proper tightening of the bolts of fastening the element to the crankshaft, and the correct moment must be observed.

When carrying out troubleshooting work, you must comply with the correct moment of tightening the fastening bolts.

Defect Fifth: Malfunction and Wearing Threads Holes Designed for Fastening Bolts

Causes of fault:

• violation of the assembly Details: incorrectly located or fixed the hook of the flywheel;
• the device is worn with long engine operation.

Progress:

• replacement of the element;
• drilling damaged threads, cutting new, if possible;
• checking how the flywheel casing is fixed, corrected with incorrect position;
• balancing details.

It is worth noting that with any actions that are associated with the replacement of the element, it is mandatory to carry out the balancing of the crankshaft assembly with the disk and flywheel, after which it can be used.

This plays an important role in the subsequent correct work of all the details. It is also necessary to check whether the flywheel cover is located correctly and is fixed.

Procedure when replacing the element

When replacing the item, you must first remove the part. At the same time, it is necessary to navigate the following actions algorithm:

1. Remove the gearbox in the car.
2. Remove the flywheel casing simultaneously with the slave and pressure disk.
3. The fixation of the element with a screwdriver, while it will not turn into the bolt turning.
4. Disposhable of six bolts for fixing the flywheel in an internal combustion engine. They should turn the cross-crosswise, which significantly facilitates the task.
5. Remove the element and support washer. At the same time, you need to remember the position of the flywheel relative to the observation mark.

Installation of the new design is also carried out in stages:

1. Installing a new part in the same position, in which the previous one was installed.
2. The installation of all the remaining elements is in order to remove, while you need to pay attention to the fact that the woven cover is correctly located, and the moment of tightening the fastening bolts was within the recommended values \u200b\u200b..

It must be borne in mind that the fastening bolts of the element should be tightened evenly, crosswise, after which it is necessary to check how the item itself is standing: after the tightening there should be no distillation and slopes, so that the wear is not rapidly. When tightening the bolts, the correct point should be observed - approximately 100 N * m.

After the removal of the details cannot be wrapped the crankshaft, because at the same time installing a new design may be difficult. But if all the same crankshafts have been turned, you need to install the cylinder piston number 4 to the upper dead point position, after which you should install a new part to your place according to the location of the tag. With the correct installation and operation of the element in the engine, the duration of its smooth operation will be longer, the symptoms will not appear, and the repair will not be required for quite a long time. It is important to properly carry out all stages of work - from the removal of the old part before tightening the fastening bolts. Also worth paying special attention At the time of tightening fixing bolts: it should be approximately 100 N * m.
