I want to ask. My rear-wheel drive also failed. I checked the resistance of the motor: the result is infinity, that is, an open circuit. Are these faults? How much should the resistance of a working motor be? Yes, and how much does a new one cost if ordered from you? Thanks in advance. P.S. Volvo XC90 3.2 car, 2007. Canadian version.

Resistance to infinity - this is clearly a lack of contact. in the motor itself, I think the brush assembly. The oil seal loses its tightness, the oil enters the electric motor, there are coals on the brush assembly. coal dust. butter. the picture is completely unpleasant. In my other video, it is shown on an example from Foltz. I didn't measure the resistance. this is worthless, the value of the current in the circuit is a much more important indicator. but in this case it doesn't matter already. there is no current at all. Email me WIN and I will answer the pump.

Please tell me how to find you or your phone number, I also have a problem with the rear axle, I want to contact the professionals, I'm looking forward to it.

First, write me an email, a description of the problem, which car, WIN. In the meantime, advice - if the fuse has blown. do not put more power. better not to touch it at all.

I answered in a personal. Clarification for everyone - flushing the entire coupling, replacing with a new pump, filter, sensor and oil is the default. As a result, a working clutch is guaranteed.

Valery, welcome! xc90 v8, haldex 3, 2008, no rear-wheel drive .. Is it possible to determine without vida if the matter is in the pump, or in the temp / pressure sensor, or just a clogged filter? angular is normal, fuse 23 intact, civilization is far away)) thanks!

Video (click to play).

If there is another way to erase errors from the computer's memory, then you can check the pump by turning on a 12 V and about 60 W lamp in its place. If the lamp shines, then the pump, if not, then you need to look further. The sensor is only replaced by a known serviceable one. The fact is that the computer forcibly disconnects the clutch if many sensors, ABS, steering angle sensor, etc. fail. If you do not replace them, just erase errors. the clutch will turn on for a while, and then turn off again.

noobs, the pipe is too lazy to remove and create everything with high quality.

This is not a video repair manual, it shows what is causing the problem. The pipe is removed when the coupling is removed. It's not me too lazy to do a complete disassembly, clean everything and then be calm about the result without re-disassembly. This is you, the owners of not the cheapest cars, sometimes it takes a long time to persuade you to do everything efficiently, and not patch holes. and then only those that are larger.

They stole a dem block, do not tell me about the car 2004 2.5T (wines model range 2005) which dem model to look for or can it be from any year?

Hello. And for prevention, you can do this? And in general, if smart masters, then get up to THAT, the question is where and for what? Thank you.

Repair of the electric motor of the Haldex coupling pump

Hello everyone!
Arrived in my stable: XC 90 2.5 transition end of 2006. mileage 94t.km.

The drive is dead, or rather email. Buchler motor due to wear of brushes and pantograph

This report will probably be useful to those who are independently engaged in the repair and maintenance of a / m and have learned to remove Vag connectors and more without breaking.
All questions (troubleshooting procedure: - the fuse / bushing / electric motor and its resistance / errors / oil / filter) are thoroughly chewed on this and other forums, for which special thanks to the Forum users. Therefore, I will try briefly.
The underdrive was found at the first snow - just took the hippo and was going to register it. I put it aside. Errors on inf. I did not see the display, the fuse 23 is intact, I did not go to the servicemen.
The culprit was found and recovered on his own.

The Internet has shown that Haldex pumps are the same on Audi, Foltz, Skoda, Volvo, Land Rover. Differences in the place of e-mail. Wires with a chip and a housing cover.I have a plastic one, there is an inductor and a capacitor on the brush pad.

Current collector donar motor: Mabuchi gear motor from power windows "Granat" VAZ 2109 and others - 940r. Eight slats, the right size.

The photo report contains comments on what you should pay attention to.

That's all. The drive is running. Old oil is much thicker than new oil. The old dirty one was only slightly in the area of the filter, then the glass was clean. In my case, I considered it unnecessary to replace the oil seal and bearings. Although all of this can be purchased. Time spent two days, money donor / oil / filter / bubble turner / gasoline / 3000 rubles. Work on your own.
I didn’t hear the pump when I was running, even under the car in the hole. Apparently the algorithm of work is not constant (perhaps I am mistaken).

P / S / Because at the moment is still explo. AUDI A6 AVANT quattro on automatic transmission, my opinion: Thorsen is more serious and more pleasant in a snowy mess, and without any problems already 335t.km. Perhaps the electronics in combination with Haldex gives a safety advantage at speeds - we'll see.

Volvo XC 90 R 012 ›Logbook› Haldex clutch pump or Drift on the XC 90. You need to be able to drift correctly on any car, but especially on the Volvo XC 90, given that all these systems that are on the car and are designed for.

Volvo XC 90 Burunduk ® ›Logbook› Haldex clutch oil change. Cleaning the pump. Since it is still planned to completely dismantle the cardan, we remove the front "strut" SIPS, as VOLVO calls it.

In modern all-wheel drive Volvo cars, the Haldex Gen V clutch is used. It works more quickly, clearly. Oil pump prevention involves the following steps: dismantling the Haldex clutch oil pump.

Glass washer fluids. I thought today to change the filter and oil in the Haldex, it's good that I started by unscrewing these bolts. The lower one unscrewed, but the upper one ... The places there are very close to each other ... Maybe I will adapt which one they have already built for these cases? And so in an earlier version of this Siemens product there was a pump and a solenoid, like mine. The front CV joint can be removed from the flange without any problems ... set aside. Well, we have what we have.

Please login or register. Haldex Coupling - A Bit of History The Haldex coupling was invented by Swedish rally racer and engineer Sigward Johansson. The company has finalized the design of the clutch, since it was originally intended for flexible and precise control of the differential lock. Haldex clutch - design and principle of operation Haldex clutch is located in front of the rear axle differential of the machine. Its input is connected to the cardan shaft, and its output is connected to the gear wheel of the reducer.

The structure consists of a mechanical part and an electronic control unit. The mechanical part contains an axial piston pump with a working piston connected to the input shaft of the clutch, a set of friction discs, as well as a drive shaft with a disk cam and a drive head.

Part of the friction discs are connected to the drive shaft, and part to the driven shaft. The interior of the Haldex coupling is filled with oil.

It also contains hydraulic elements: an electric make-up pump, a filter, pressure and inlet valves, a hydraulic accumulator, a safety valve and a pressure regulator. When the wheel of the front axle is slipping, the rotational speed of the driving and driven shafts of the clutch becomes different. As a result, the piston, under the influence of a cam washer, makes movements, building up pressure and compressing the friction discs. As a result, the input and output shaft of the clutch are connected.

This pressure is maintained by a hydraulic accumulator. In addition, the latter evens out pressure fluctuations. The regulating valve, located in the pressure regulator, distributes it to the discs.

The Haldex clutch electronic unit operates on the basis of ABS sensors. It receives data on the speed of rotation of the wheels, braking, acceleration. If there is an electronic stabilization system in the car, it has the priority right to activate over all-wheel drive.

Haldex clutch block control signals are directed to the oil pump and control valve motor. Unlike the first generations, which connected the rear axle only when slipping, the latter is able to activate four-wheel drive even before the car starts. Now the Haldex coupling is used by the world carmakers Volkswagen, BMW, SAAB, VOLVO.

Found on freelander, they are the same. Volodya, here is the honestly earned information on the Haldex coupling.

The plug-in rear-wheel drive on Volvo is a Haldex development, but the manufacturer of all modules, pumps, electronic units dubs DEM, without going into details of the design features of the entire system, we will give general concepts of the principle of operation of the rear-wheel drive.

On Volvo AWD XC90, XC70, XC60 - the front-wheel drive is leading (works constantly), and the rear one turns on when one of the front-wheel drive wheels slips. It looks like this: ABC sensors read the speed differences on the front wheels and send a signal to the electronic control units that control the rear-wheel drive engagement clutch.

The clutch assembly (design features and appearance changed, depending on the year of manufacture of the car) - the principle of operation remained unchanged.

DEM clutch - a device consisting of a set of friction discs controlled hydraulically
Electronic control module DEM
DEM clutch pump - creates pressure in the clutch, directly starts the pressure providing clutch clutches that drive the rear gearbox.
Sensor - reads clutch pressure.

In the clutch itself there is a certain amount of oil necessary for the operation of the system, since the conditions are heavy, the oil loses its properties and becomes contaminated with chips, production from the friction clutches.

The oil system has two filters, one main (filter element) and a mesh on the Haldex pump. When servicing the clutch, we offer our customers only original Volvo spare parts.

At the moment, the Volvo manufacturer does not prescribe clutch maintenance in the maintenance regulations (only upon failure). There is no oil drain plug on the coupling itself, only a technical hole for filling and checking the level.

It is safe to say that rear-wheel drive failure is a common malfunction that can be prevented or delayed. Most often, the DEM pump fails due to clogged filters and oil system channels. It is possible to identify a failed part in case of a rear axle malfunction only after carrying out computer diagnostics (malfunctions of electronic systems can be found in the self-diagnostics section). The DEM pump is far from the only cause encountered. In some cases, the clutch itself, the control module, sensors, SAS sensor, wiring, etc. break down.

There are several solutions for changing the oil and filters in the Haldex coupling:

- The so-called "partial" oil change means changing the filter, flushing the pump mesh, sucking out the remaining oil with a syringe and filling with a new one.

- "Complete" replacement - removal of the coupling itself, complete disassembly with flushing of all channels and replacement of the filter. This procedure is necessary when the oil thickens strongly (loses its properties) and it is not possible to remove all the used oil without complete disassembly (visually similar to black grease).

We consider the most optimal solution to service the Haldex coupling every 60 thousand km, maximum 90 thousand km.

In case of failure of the DEM pump or lack of maintenance for more than 100 thousand km, it is necessary to change the oil with a complete disassembly of the coupling.

HALDEX coupling pump - replacement (remove-put) - 1750 ₽

HALDEX coupling filter + partial oil change with removal of the dem pump (cardan shank) - 2400 ₽

HALDEX coupling filter + complete oil change (su couplings + disassembly and cleaning of all channels) - 3600 ₽

Salut valeriu! Am un passat b motion cu km si nu stiu daca i a fost schimbat vreodata uleiul iar la reprezentante mi s a spus ca uleiul de la haldex nu se schimba, este lifetime, desi in cartea masinii scrie clar ca se schimba la. Km iar service urile la care am fost nici nu stiau de acest cuplaj. Ce ma sfatuiesti la fac?

Good afternoon, how long does the Haldex motor oil seal go?

Salut valeriu. Am un golf. Tdi motion. Am martor esp in bord dupa km sau minute la relanti. Mi s a zis la service ca pompa haldex ar fi defecta ca nu creeaza presiune dar eu am ridicat masina pe rampa si se invart si rotile din spate, insa asta fara martorul esp in bord. Spune mi te rog daca stii pe cineva priceput la haldex in iasi? Nu gasesc in romania de unde sa comand o pompa haldex. As putea comanda de la tine. Cam cat m ar costa?

Salut, am un audi tt n quattro. Se aude un bazait ciudat la calculatorul haldex. Si totodata am si becurile esp si abs in bord aprinse. O sugestie in rezolvarea problemei sau ce anume ar trebui schimbat? Multumesc.

Va salut! Puteti va rog sa imi lasati o adresa de email va rog? Multumesc!

Salut. Ma poti ajuta si pe mine cu ceva. Am un volvo din. T awd. Si am defecta pompa de la haldex. Vreau sa o schimb si filtru la fel dar nu stiu cat ulei sa pun inapoi in haldex. Ma poti ajuta cu informatia asta? Multumesc

Buna, ati putea sa imi lasati un numar de telefon sa va contactez

Hemorrhoids generally bother with this. As in any other business

And there are a lot of peasants - what are they talking about, and I generally keep quiet about the OBS radio :)
Closer to the topic: they say that Haldex has oil for the entire service life of a car, and it is written in the manufacturer's recommendations, BUT. There's a filter in there. Therefore, those who have a HEAD on their shoulders change both the oil and the filter.

Yes: leaving at the expense of others is not good.
I think that everyone here understands that a remanufactured and tested pump for 140 with a 3-month warranty is much worse than in a h.z. what condition (according to the dismantler - 6 months of operation) for 180 and 3 months. guarantees.

Good afternoon “Vint0406”!
I would like to contact you, please write your phone number.

Added after 23 minutes 30 seconds:
Vint0406, I apologize in advance, maybe this is off topic, please tell me how much you can drive with an inoperative pump? Will there be any consequences? It's just that I'm in St. Petersburg now, there are no remanufactured ones here, and a new one with a replacement is offered for hellish sums, so I want to know if it will be okay for me to get to Minsk on a front wheel drive. (maybe it's bad for an automatic transmission or something else)
PS
Yesterday I spent half of the evening on the Russian forums and did not find the specifics.

The owner of a 2012 Volvo XC90 car with a 2.4 liter D5 diesel engine contacted the Volvo Station car service in St. Petersburg.

The reason for petition: malfunction of the gearbox and the HALDEX coupling.

The service specialists carried out a turnkey repair of the Haldex gearbox and coupling.

The first video shows the hum of the gearbox bearings, the second shows the old gearbox oil with metal shavings.

All work and purchased spare parts are covered by a guarantee.

Our specialized car service Volvo SV Group is open for mutually beneficial cooperation with legal entities and individuals - owners of corporate and private vehicles. The technical potential of the service center and the experience of competent specialists allows us to quickly process all applications and effectively resolve issues related to diagnostics, maintenance, including maintenance of the Haldex coupling, replacement of spare parts or overhaul of a car.

For the correct functioning of the vehicle, the serviceability and debugging of all key mechanisms and every smallest part of the block is important. First of all, this concerns such an important and technically difficult unit as the Haldex clutch, with which modern manufacturers equip transmissions of all-wheel drive vehicles of various models and brands.

The Swedish-made Haldex coupling is a patented device, which in practice is a complex design, consisting of the following components:

hydroaccumulator,
wet multi-plate clutch,
electric hydraulic pump.

The principle of operation of the clutch is due to the clear coherence of all components that are activated when the car moves (at any speed) forward or when reverse is engaged. The main functional task of the unit is to control the distribution of torque along the axes.The mechanism is controlled by a built-in electronic unit in full agreement with the rest of the vehicle's control systems.

Employees of the Volvo SV Group car service know from their own experience how important it is to determine the breakdown of a part in time, before the consequences of wear or mechanical damage to the element lead to critical consequences. Timely professional diagnostics and quality maintenance of the Haldex 3 clutch or the fourth generation clutch equipped with an electric pump and receiver guarantees the driver safety and confidence on the road.

According to the regulations established by the manufacturer, the standard maintenance of the Haldex 4 clutch - in particular, an oil change, is assumed every 60 thousand kilometers. Experienced motorists are skeptical about these indicators. Their opinion is supported by mechanics and domestic experts, who argue that the frequency of the event can be influenced by subjective factors, it is worth changing the oil at least once per 30-40 thousand run.

To restore and maintain excellent technical condition of the coupling, it is recommended to perform the following work:

timely oil change;
repair (bulkhead) of the pump;
flushing the coupling;
fuse replacement;
anti-corrosion treatment of the clutch control unit cover.

It is worth noting the level of skill of the employees of the technical center, who systematically undergo professional training at the production facilities of Volvo. Our specialists have a strong theoretical base and practical skills, they successfully service the Haldex 4 clutch, which, according to the developers, belongs to the category of maintenance-free vehicle units.

In the article, we will consider how the oil is changed in the Haldex Volvo XC90 clutch. The 4th generation clutch is provided as an overview.

The design feature is that the filter is located in the upper part, in contrast to the 3rd generation, in which it is located on the left. There is no filter in the 5th generation.

The considered oil change is not suitable for the 3rd generation, because the pump cannot be removed without removing the cardan.

The manufacturer recommends changing the oil every 60-80 t.km.

Oil in an amount of about 750 grams, catalog number 31325136

Rem. kit catalog number 31325173

Filler bolt gasket, p / n 11998

We install the car on a flat surface, for convenience on a viewing hole or lift.

Disconnect the terminals of the Haldex control module and unscrew it.

We unscrew the pump cover, which will help to pull it out without dismantling the cardan and unscrew the pump itself.

When removing, substitute a container to drain the oil.

When the remaining oil is drained, we proceed to cleaning and troubleshooting the clutch pump motor.

Having separated the motor and the body, we check the condition of the brushes and clean out the internal dirt with a cleaner. We also remove the pump mesh and clean the dirt.

After washing, we leave the parts to dry and proceed to replacing the filter.

When the oil change approaches in the Volvo Haldex clutch with the cardan shaft installed, it becomes difficult to unscrew the filter bolts on the way.

The bolts are located at the top and you will have to work hard to unscrew the bolts.

After the filter mounting bolts are unscrewed, remove the filter cover of the Haldex coupling. To do this, you can pry it off with a flat screwdriver.

A plug is installed under the cover, which must be replaced. The lid is located in a hard-to-reach place and you can use a sharp heated object to remove it to pierce the lid and pull it out or, for example, an awl bent at the end. A new plug is supplied in a repair kit.

The filter installed under the plug is removed and replaced with a new one. Before installation, it is recommended to lubricate the new clutch oil filter with clean oil and install until it clicks.

We also lubricate the seal of the new plug and screw it into place.

Next, we proceed with the installation of the Haldex coupling pump, before installing which we cleaned the seat. Also, before installation, we lubricate the seal on the pump with new oil.

In order for the pump to be freely installed in place, its back cover can be slightly sharpened. This will allow you to immediately screw the pump body and during installation it will not cling to the cardan flange.

Reinstall the clutch control module and connect the connectors.

We unscrew the filler bolt, which also serves as the oil level.

Fill with oil until it flows and tighten temporarily with the old washer.

We remove the car from the lift or drive down from the inspection pit and drive a distance, for example, around a house or a car service.

This procedure is necessary for the oil to fill the filter and pump completely.

We re-install the car on a flat surface, for this a viewing hole is suitable, and we unscrew the filler plug of the Haldex coupling.

Add oil until oil flows out.

Pump out 40 ml from the filled coupling with new oil, for example with a syringe, and this will be the correct level.

We tighten the plug-bolt using a new washer.

It's as simple as it turns out that you can change the oil in the Haldex Volvo XC90 clutch yourself.

To replace and repair an ABS sensor on a VOLVO S70, it is not at all necessary to go to a car service - this work can be easily done in your own garage. Having poddomrkuv the car, remove the wheel and find the ABS sensor behind it. We remove the sensor very carefully, the main thing is that the wire does not break. If you watch the video instructions, you can easily cope with this work yourself. The use of materials without the written consent of the authors of the site is prohibited!

And for prevention, you can do this? And in general, if smart masters, then get up to THAT, the question is where and for what?
Thank you.

Qarta Avenis: They stole a dem block, do not tell me about the car 2004 2.5T (wines model range 2005) which dem model to look for or can it be from any year?

Valeriu Prisacaru: This is not a video repair manual, it shows what is causing the problem. The pipe is removed when the coupling is removed. It's not me too lazy to do a complete disassembly, clean everything and then be calm about the result without re-disassembly. This is you, the owners of not the cheapest cars, sometimes it takes a long time to persuade you to do everything efficiently, and not patch holes. and then only those that are larger.

RelaxSky: noobs, the pipe is too lazy to remove and create everything with high quality.

Valeriu Prisacaru: If there is another way to erase errors from the computer's memory, then you can check the pump by turning on a 12 V and about 60 W lamp in its place. If the lamp shines, then the pump, if not, then you need to look further. The sensor is only replaced by a known serviceable one. The fact is that the computer forcibly disconnects the clutch if many sensors, ABS, steering angle sensor, etc. fail. If you do not replace them, just erase errors. the clutch will turn on for a while, and then turn off again.

Alex Pa: Valery, welcome! xc90 v8, haldex 3, 2008, no rear-wheel drive .. Is it possible to determine without vida if the matter is in the pump, or in the temp / pressure sensor, or just a clogged filter? angular is normal, fuse 23 intact, civilization is far away)) thanks!

Valeriu Prisacaru: I answered in a personal. Clarification for everyone - flushing the entire coupling, replacing with a new pump, filter, sensor and oil is the default. As a result, a working clutch is guaranteed.

Valeriu Prisacaru: First, write me an email, a description of the problem, which car, WIN. In the meantime, advice - if the fuse has blown. do not put more power. better not to touch it at all.

Video (click to play).

Valeriu Prisacaru: Resistance to infinity - this is clearly a lack of contact. in the motor itself, I think the brush assembly. The oil seal loses its tightness, the oil enters the electric motor, there are coals on the brush assembly. coal dust. butter. the picture is completely unpleasant. In my other video, it is shown on an example from Foltz. I didn't measure the resistance. this is worthless, the value of the current in the circuit is a much more important indicator. but in this case it doesn't matter already. there is no current at all. Email me WIN and I will answer the pump.
