Repair of the full engagement clutch Hyundai drive Santa FE, Tucson, IX35, Kia sportage, Sorento

Frequent movement over difficult-to-pass places while the car is running leads to overheating and failure friction clutch... In standard operation, the clutch lasts about 150 thousand km and the cooling time is about 10-15 minutes.
The main signs of a malfunction are jolts when driving, jamming and stopping. rear axle when turning.
If computer diagnostics did not show an error, the car must be inspected on a lift to identify mechanical failure... Qualified diagnostics will help to identify the cause and detect a malfunction of the engagement clutch all-wheel drive, which are electrical connectors, the winding of the electromagnet (an open circuit often occurs), and the bearing itself.
Repair of the rear axle coupling Kia Sportage, Sorento, Hyundai santa FE, Tucson, quite time-consuming work that needs to be done in a specialized center.

The cost of repairing a coupling with spare parts is approximately 10,000 - 12,000 rubles. depending on the required spare parts.

First of all, we shoot cardan shaft, then disconnect the chip and unscrew the four bolts from the rear axle. Remove the clutch. Disassembly begins with unscrewing the shank nut, with a three-blade puller we take out the flange and the coupling housing, checking immediately for leakage. Next, remove the retaining ring from the back cover, the cover itself and take out the shaft. Check the friction pack for damage. If there is a malfunction of the friction pack, we replace the clutch with a new one, since the original manufacturer does not supply this component separately. If there is no defect, then the part and the body itself are washed with a brush in a separate tank with a cleaner for 5-10 minutes. After these manipulations, we assemble the friction package in strict sequence. It consists of several plates, an overrunning clutch gear, six balls, an overrunning clutch upper plate, several clutch discs that fit one piece at a time. The oil seal also changes to a new one, to top cover couplings. The manufacturer produces all-wheel drive viscous coupling repair kits consisting of a bearing, an oil seal and the flange itself.
After the viscous coupling has been assembled, ATF SP3 oil is poured, the cover on which the oil seal was changed is closed and the retaining ring, the coupling housing, is installed without much effort. When scrolling the body and carefully examining it, we determine whether it is necessary to change the bearing with an oil seal near the coupling body.
After assembly, the clutch is installed in reverse order on the vehicle. If the threads are damaged, the bolts must be replaced with new ones. Install the driveshaft.

Good day, fellow motorists! The Zapkia car service team is pleased to continue the cycle of materials on self-repairing locksmiths modern cars... Do you want to learn how to repair your car without a service station? Change quickly and efficiently necessary spare parts and consumables? Our articles and videos will help you with this!

Today we have a story about the features of the repair. The medium-sized crossover is very popular among Moscow drivers due to its cross-country ability, high power ride and exceptional ease of maintenance.

Nevertheless, after a long run, the car often begins to emit very noticeable jolts. Many drivers neglect such "symptoms", and it is in vain - a broken one deprives you of the possibility of normal control of your car. Note that even under proper operating conditions, the clutch is capable of serving about 100-150 thousand kilometers.

Repairing an all-wheel drive clutch is a laborious process. Of course, the best solution in the event of characteristic shocks, the car will be returned to the service station - only high-quality diagnostics will give a 100% guarantee of the causes of the breakdown. But if you "know" your car quite well, and are ready to take on the repair yourself - this article is for you.

Causes of clutch malfunctions

So what will cause the premature failure? First of all, careless driving on bad roads... When you move this way, your car's suspension literally falls into holes, and the clutch is physically damaged. In addition, the "harbingers" will be disable ABS and ESP, as well as the error "Differential" when driving. No matter how much you want to avoid inconvenience, you will have to climb into the rear axle.

Our advice: if you have any problems with the clutch, contact a proven workshop. Yes, you will have to overpay a little - but you will receive the most qualified and prompt service. In addition, if you contact car service Zapkia- if necessary, we will install a new original clutch on your Santa Fe, Sportage or any other korean car, and our prices for plumbing repairs are the best in Russia!

Let's go back to the clutch. They are hydromechanical in Hyundai Santa Fe, as well as in KIA Sportage. This decision Korean manufacturers means the perfect cost benefit. However, the clutches are short-lived - the hydromechanical clutch easily overheats while driving, and the machine becomes mono-drive. Santa Fe and Sportage clutch failures are some of the most common chassis failures.

If breakdowns have already occurred, it makes sense to purchase new clutch... In the Zapkia auto parts store, the price of an all-wheel drive clutch for Santa Fe / Sportage is minimal! In addition, we offer exclusively original components - which means that even such a "fragile" mechanism as a clutch will serve you for many years!

Remove the all-wheel drive clutch. Frequent malfunctions

So, remove the faulty clutch. We lift the car on a lift, climb under the bottom, and first remove the propeller shaft - in both models Korean cars it can be removed without any problems. Next, we unscrew the bolts from the rear axle (there are only 4 of them), and carefully remove the clutch itself. It makes sense to carry out further disassembly on the table.

The muff is in front of us. We twist the shank nut, then carefully remove the flange. We immediately check the clutch for leaks - if there are any, it makes sense to buy a new clutch immediately.

We remove the retaining ring located on the back cover, then the cover itself, and remove the coupling shaft. There is a special friction pack, which must be checked very carefully - the fact is that this pack cannot be changed or repaired, since friction packs are not produced separately. Accordingly, we found a package malfunction - you need to change the entire clutch.

In any case, the package needs to be cleaned up. We wait 10-15 minutes and assemble the part. Note that Santa Fe / Sportage friction packages can only be disassembled independently if there is a mechanic friend nearby, so if you are not sure about the success of the disassembly, it is better to bring the whole clutch to the service.

We pay special attention to the bearing - if one of them is defective, the coupling cannot be used. Both Hyundai and KIA produce special clutch repair kits that contain a replaceable bearing, oil seal and flange. The price of such a kit is minimal!

Even if the friction pack is normal - with a high degree of probability, the clutch seals certainly need to be replaced. We change the oil seal located on the top cover. It is important to use high-quality consumables here, because even an oil seal can quickly render the all-wheel drive clutch unusable, causing significant leaks. special oil... Coupling oil seals are needed, or repair kit for Santa Fe or KIA Sportage clutches? Contact the Zapkia store - the price of original consumables will delight you!

Clutch service is virtually over. It remains only to fill in a quality one, because the operation of the clutch as a whole depends on its viscosity! Fill, assemble the clutch, install it on the rear axle. Clutch problems solved, congratulations!

Results. Service station or DIY repair?

We hope we managed to talk about self-repair couplings korean four-wheel drive cars without missing a single nuance. Nevertheless, we strongly advise you to carry out this repair at a service station - firstly, there may not be a repair kit at hand, ATF oils or other consumables. Secondly, it is sometimes not easy to remove the clutch by crawling under the bottom of the car. Well, and the main advantage is the professionalism of the mechanics!

Having trouble with the clutch, or suddenly "knocking"? Come to the service station Zapkia! Good luck friends!

With the onset of hot weather, many motorists are concerned about the health of the air conditioning system. If she is in all right, then there are no problems with the operation of the air conditioner. But what if cool air stops blowing from the deflectors?

The air conditioning system of a car includes many units and parts, each of which performs its own specific function. Violations in the operation of at least one element can significantly affect the performance, or even completely disable the unit. One such device is a compressor.

The compressor is perhaps the most important and expensive element climate system any car. However, its design contains another unit, the purpose of which is to make the compressor do its job. This is an electromagnetic clutch for turning on the air conditioner.

The coupling provides
mechanical connection of the compressor pulley and its drive shaft... When the system is disabled, the pulley rotates freely, and the internal mechanical part the compressor remains stationary. But as soon as you press the A / C button, the electromagnet pulls the clutch plate to the pulley, and the compressor mechanisms are activated.

In most cases, couplings are disposable and are not supplied as spare parts. Therefore, at first glance, repairing the air conditioner compressor clutch on a car turns out to be impossible, and auto repair shops are forced to resort to different ways recovery. However, some compressor models still provide for its replacement.

A malfunction of the electromagnetic clutch can be identified by the following symptoms:

• the switched on air conditioner does not supply cold air;
• when the power button (A / C) is pressed, the first fan speed does not turn on;
• the characteristic click of the electromagnetic clutch is not heard;
• the air conditioner suddenly stopped "cold".

If you have similar symptoms, then you should immediately contact a specialist who will conduct a detailed diagnosis, determine a non-working unit, and therefore what kind of work will require repairing the air conditioning compressor clutch.

Unit check
usually consists of the following operations:

• measuring the working pressure in the system (it must be at least 20 atm);
• checking sensors and thermostat;
• examination electrical circuits and connectors;
• checking the compressor and electromagnetic clutch.

The last procedure is performed when removed belt auxiliary units... Pressing the air conditioner power button should be accompanied by a click (not always), and when turning the compressor pulley with your hand, slight resistance should be felt. In a free state, the pulley usually turns very easily.

As mentioned above, the repair of the air conditioner compressor electrofusion, as a rule, comes down to its replacement, and only in some cases only experienced craftsmen are able to repair the part.

Most common a clutch failure is an open thermal fuse, which is designed to protect the clutch from overheating. The nominal response temperature is 190 C °, and it works only once. The malfunction is diagnosed with a multimeter for an open circuit. The coupling is replaced with a similar value. The fuse is usually filled with a compound that will need to be removed. New item soldered to the contacts with refractory tin solder and filled with a suitable epoxy compound (the composition must be designed for a temperature of at least 220 C °). In addition to the fuse, there is also a break in the solenoid coil. Such a malfunction is quite rare and happens if a "bug" was installed instead of a thermal fuse. In this case, the electromagnet cannot be repaired.

Another clutch malfunction is associated with bearing wear and is expressed in increased operating noise. This is checked by rotating the compressor pulley. The pulley should rotate easily without extraneous sounds, such as rumble and grinding, should not be. Worn out
the bearing becomes very hot during operation, and the rotation speed of the compressor pulley is approximately twice the rotation speed crankshaft... Overheating of the bearing often causes failure of the thermal fuse.

The new bearing is selected according to the designation, and the manufacturer plays a very significant role. You should not save on this, cheap copies have a very small resource and can fail after a very short time. The replacement procedure is often fraught with certain difficulties. Firstly, the landing is made with a high interference fit (there are also strained ones with preheating seat). Secondly, the bearing is additionally fixed by means of point beading of the edges, which excludes its displacement when the unit heats up during operation.

To carry out the replacement work, special equipment and extreme care are required, since there is a risk of deformation of the pulley and damage to the bearing seat. This, in turn, can provoke radial runout pulley, increased wear and cliff drive belt, as well as compressor breakdown.

If a stress fit is used, then the pulley is first heated to a temperature of 200-250 degrees, and then a new bearing is pressed in. It is important to control the temperature, because strong heating can lead to a violation of the structure of the material and even warping of the part.

Coupling (electric coupling) connection of the rear axle Hyundai, KIA

Scheme of four-wheel drive with electromagnetic clutch Hyundai, KIA

On many cars, all-wheel drive is plug-in. The four-wheel drive on Hyundai vehicles, KIA, drive on rear wheels here it is connected automatically, through an electromagnetic clutch.

All-wheel drive electromechanical clutch

The clutch is controlled by the Hyundai, KIA four-wheel drive control unit. The principle of operation of an electromechanical clutch is practically the same as that of a clutch. When voltage is applied to the clutch, the disks inside the clutch are pressed against each other and through them torque is transmitted to the rear wheels.

Four-wheel drive is connected by Hyundai, KIA only when the front wheels slip, and after about the second wheel turn. When the need for all-wheel drive is no longer necessary, it turns off. Also, the drive turns off when a certain speed threshold is exceeded, because the clutch is not designed for high speeds.

There is a four-wheel drive test lamp on the dashboard. When the ignition is turned on, the lamp lights up and a self-test of the system is performed. If everything is in order, then the lamp goes out. If there is a fault, the lamp will continue to burn.

Unfortunately, there are no signs that the drive has turned on in the car. But you will easily understand this when you get stuck and start to slip. When the rear wheel drive is connected, you will feel a slight jolt, and the car will slowly climb out of the blockage, there is no need to force the car to slip, because of this, the clutches in the clutch burn out.

Torque to rear wheels transmitted through the transfer case (2), front cardan shaft (4), electromagnetic clutch (5), rear cardan shaft (6), rear axle reducer (7) and rear wheel drives.

All-wheel drive transmission

Four-wheel drive transmission scheme

1 - gearbox, 2 - transfer case, 3 - front wheel drives, 4 - front cardan gear, 5 - electromagnetic clutch, 6 - rear cardan gear, 7 - rear axle reducer, 8 - rear wheel drives.

Transfer case

The transfer case is rigidly attached to the gearbox housing. The transfer case is driven by a differential box. The transfer case itself is two-stage. Center differential there is no transfer case, and the torque redistribution between the axles is performed by an electromagnetic clutch, depending on road conditions.

Shafts cardan transmission made of thin-walled steel. The electromagnetic clutch transmits torque to the rear wheels only when the clutch is partially or completely blocked from the signal from the four-wheel drive control unit.

The drive unit receives information from the engine control unit and, based on the received data, turns on or off the clutch, thus supplying or removing torque to the rear wheels.

The block receives the following information:

- longitudinal acceleration of the vehicle (from the acceleration sensor under the dashboard console)

- vehicle speed and wheel speed difference (from wheel sensors)

- braking mode (from the ABS unit)

The electromagnetic clutch is maintenance-free.

A new clutch costs from 45000r to 60000r, from us you can purchase a selected clutch with a guarantee for 25000r. We give a 3-month warranty for our coupling.
