If the power steering fails, it is possible to drive the car, but the steering wheel will be difficult to turn and will become heavy. To partially replace the power steering oil, you will need a syringe with a tube and the oil itself, enough so that at the end of the work it will no longer be dark.

[em]Continuation of the report (+) - Alexander - What is the frequency of changing the power steering oil? I thought about just disconnecting the hose...

At this moment, you must not allow the power steering oil to completely drain from the reservoir into the system and allow air to be sucked in! You can drain everything old so that it doesn’t mix with the new when topping up.

To partially replace the power steering oil, you will need a syringe with a tube and the oil itself, enough so that at the end of the work it will no longer be dark. The fitting is located to the right of the gearbox axis in the top cover and is secured with 4 bolts in the center - adjusting the gearbox backlash; internal hexagon; replacing power steering hoses on a Chevrolet Niva; lock nut. Drive onto an overpass, or jack up the car so as to hang the front wheels of the Chevrolet Niva, in order to be able to easily rotate them with the engine not running.

The oil itself is not aggressive to your hands or paintwork, like brake fluid, for example? The screw is located on the gearbox cover, which is secured with four bolts. Am I now studying the picture in the manual?

You can drain everything old so that it doesn’t mix with the new when topping up.

Next, assemble the line, pour new water into the reservoir, one swings the steering wheel between the extreme positions without starting the engine, the other unscrews the fitting with a key of 8, as on the brake fittings, the cone-to-cone fit is the same and bleeds the air. In the process, add oil to the reservoir. When liquid flows through the fitting, close it.

Start the engine, one rotates the steering wheel as stated above, the other, in extreme positions, bleeds air through the fitting, CAUTION, as there is a possibility of getting a jet in the face, there is pressure on a running engine. As soon as one fluid flows, consider the process complete, tighten the fitting well. This sequence of actions was carried out personally on the advice of a person from the Elex warranty station; I did not find an accessible manual anywhere.

After replacing the steering wheel became even lighter, 1 click the flight was normal. After replacing, wash your face and hands; no traces or irritation were noticed. The fitting is located to the right of the gearbox axis in the top cover and is secured with 4 bolts; in the center there is an internal hexagon and a lock nut for adjusting the gearbox play.

During operation, Chevrolet Niva power steering fluid can leak in various places, most often through hoses. As a result, the power steering oil level will drop.

Driving without fluid in the Chevrolet Niva's power steering puts you at risk of breaking the power steering pump, which costs a lot of money, since it will run dry. As a result, it will suffer serious damage and fail.

DIY power steering hose repair

High pressure hoses are used in pneumatic and hydraulic structures.
In the automotive industry, they are widely used in steering systems. Thanks to the built-in hydraulic booster, the driver does not have to apply significant load on the steering wheel when turning. However, under certain operating conditions, various deformations of tubes or hoses are possible. Subsequently, this leads to unstable operation of the unit, which can be corrected by repairing the power steering high-pressure hoses with your own hands or with the help of service station specialists.

Operating principle of EUR and power steering

Before installing the amplifier in the VAZ 2121 with your own hands, let's look at the operating principle of the systems, starting with the power steering. When the steering wheel is in the central position, it is fixed using centering springs. In this position, the liquid circulates through all elements of the system, provided that the distributor is positioned correctly.

When the steering wheel is turned, the spool moves, as a result of which the element blocks the drain lines and liquid begins to flow into one of the cylinders. In this case, the piston, as well as the rod, are exposed to oil under pressure, which leads to the rotation of the wheel, as well as the housing, in a certain direction. The spool overtakes the device body when it stops moving, which indicates that the driver has completed the turning maneuver. In this case, the spool returns to its original position, and then the hose opens to drain the liquid.

As for the principle of operation of the electric power steering, the amplifier itself is mounted on the steering shaft of the vehicle. Its component parts are connected to each other using a torsion shaft, with an installed engine speed reading controller. When the driver turns the steering wheel, the torsion shaft twists, which is detected by the torque sensor.

Hydraulic operation

Hoses, which are often called high-pressure hoses, are flexible pipelines whose main task is pumping working fluids. The transported material is specially prepared motor oils or working fluids based on mineral oils, aqueous solutions of emulsols, glycol, and greases.

Without high-quality flexible hoses that can withstand the required pressure and an extensive pipeline system, it is difficult to imagine the operation of a hydraulic booster. In addition to the direct duty related to pumping working fluid, such hoses act as dampers (compensators), increasing the operational period of connecting elements, fittings, fittings and the system as a whole.

Vibration absorption by flexible elements contributes to obtaining such results. The negative side of the phenomenon is that periodic replacement or repair of power steering hoses in worn areas is required. After all, all abrasions or kinks soon lead to the tube leaking .

Structural features of power steering hoses

In addition to working under high pressure, the power steering hose must have reduced susceptibility to the working fluids used. Thanks to this, its inner surface is made on the basis of oil- and gasoline-resistant synthetic rubber.

The outer surface is protected by layers of wear-resistant rubber. Under certain circumstances, this layer plays the role of thermal protection. It may have the following surfaces:

The outer and inner layers are separated by a metal braid. This gives the entire structure the required operational strength and acceptable rigidity. Wire layers alternate with rubberized elements.

It is customary to distinguish the following types of hoses:

  • Winding . During the manufacture of this product, turns of wire are braided evenly around the entire perimeter.
  • Braided . Each turn covers the sleeve at a certain angle to the common axis in such a way that it intersects with the turns of the previous layers. This technology increases the strength of the structure and can operate at higher pressures than the previous type.

The frame for the sleeve in some models is textile. The geometric and physico-chemical parameters of wire and rubber are standardized for various applications.

Suspected damage

During operation, motorists may encounter different types of hydraulic damage, after which repair of the power steering hoses is necessary. The following points can be noted:

  1. Manufacturer defect . This feature is typical for insufficiently known hydraulic equipment manufacturing companies. Failure is characterized by poor-quality crimping of the joint of a sleeve or fitting. This happens when the equipment is undebugged or incorrectly configured.
  2. Operational output . Damage occurs due to wear and tear during operation of the mechanism. The main problems are cord breaks, cuts and frayed areas. This often occurs due to hose sagging due to incorrectly selected length.
  3. Structural inconsistencies . Failure occurs due to the installation of equipment that does not meet the specifications specified by the automaker. In such situations, a wire rupture or fittings may break due to a discrepancy between the pressure in the system and the permissible value for the hose.
  4. Disagreement in temperature or chemical characteristics . Damage to the structure can occur during operation at an ambient temperature for which such rubber was not designed, as well as during the use of aggressive chemicals in the structure of the working fluid.

Damage to power steering hoses

The manufacturer indicates all characteristics and permissible operating parameters for each hose in the instructions for use.

Hydraulic malfunctions with which further operation of the vehicle is not recommended:

  • fittings are significantly damaged by corrosion processes;
  • significant fracture of the sleeve;
  • significant abrasion of the outer part of the hose;
  • the presence of complete or partial blockage inside the sleeves;
  • lack of sealing of connections;
  • failure of the fitting from the landing diameter;
  • liquid leakage at joints;
  • deformation or damage to the inner surface from high pressure or excess temperature.

In all cases, replacement or repair of the hose is required.

Carrying out repairs

Based on the nature of possible damage, it can be assumed that the most common repair of power steering hoses involves putting the fittings in order or replacing individual parts of the hose. To carry out the replacement, crimping with couplings will be necessary.

Tools for DIY repairs

The work algorithm may be as follows:

  1. The damaged hose must be disconnected from the system.
  2. The new hose will need to be the same length so as not to create unnecessary sagging. The measurement is carried out from nipple to nipple. At the same time, we select a hose that satisfies all geometric data and pressure parameters. The markings indicated on the outside by the manufacturer will help with this. The internal diameter will also be indicated there.
  3. When repairing a high-pressure hose, the ends are stripped both outside and inside to the metal braid. The procedure is carried out faster using debarking machines.
  4. Fittings are selected according to geometric parameters and technological thread data. Measurements are easy to take using a caliper and thread gauge. Domestic and foreign fittings may differ from each other according to several criteria, so it is better to take measurements yourself.
  5. We crimp the fittings using crimping equipment, using suitable removable jaws in each case.
  6. Using a control probe, we determine the quality of the work performed. At specialized factories, this operation is carried out using special industrial stands.

For non-standard connections, repair kits with recommended fittings must be used. You can disconnect the head of the old fitting, if it is not damaged, and solder it to the part to be crimped. This option is used in extreme cases, since the effect of this repair is short-lived.

Troubleshooting power steering hoses

Damage to the hose in most cases occurs due to frequent turning of the steering wheel with great force. Wear occurs at the hose connected to the limit valve.

When installing and repairing power steering hoses, it is necessary to take into account that the permissible pressure in the system can vary depending on car models in the range of 80...130 kgf/cm 2.

Such significant performance indicators do not allow the use of any types of clamps during repairs. You need to choose the most appropriate option:

  1. Complete replacement of the sleeve.
  2. Partial replacement of a deformed or worn area with installation of fittings on a new hose.

Humor in the topic: The worker came to the sanatorium on a voucher. In the morning, from a wild hangover, he surveys the beach... Shielding himself from the bright sun with his palm, he examines the half-naked audience: - Rest, heal... Here you can work and work!

Tools:

  • Key for 10
  • Container for draining liquid
  • Phillips screwdriver

Parts and consumables:

  • Fluid - power steering oil
  • Rags

Notes: Replace the fluid in the power steering system if it is excessively dirty. The manufacturer does not give clear recommendations on the frequency of replacing fluid in the hydraulic system, so we recommend replacing it after six years, regardless of its condition.

For use in the hydraulic system of the amplifier, the manufacturer recommends a fluid - Pentosin Hidraulik Fluid CHF11S oil. However, for technological reasons, cars starting with VIN No. X9L21230040005880 use Shell Donax TA D-21631 (Dexron II) hydraulic fluid in the hydraulic system, and with VIN No. X9L21230040006248 - Ravenol Dexron II D. Cars filled with Shell Donax oil have a mark on the tank - “*”, and cars filled with Ravenol Dexron II D are marked “R”, but on cars of the latest production these marks may not be present.

Dexron II fluids (red) cannot be mixed with Pentosin Hidraulik Fluid CHF11S (green). It is possible to completely replace the fluid after flushing the power steering hydraulic system.

When using Dexron II fluids, reduce the period of use by half the recommended time.

1. Remove the pinch bolt of the power steering reservoir reservoir bracket.

2. Unscrew the tank cap.

3. Remove the reservoir from the bracket and drain the liquid from the reservoir into a suitable container.

4. Loosen the clamp securing the outlet hose and remove the hose.

5. To prevent fluid from leaking out, plug the hole in the tank fitting and lower the end of the outlet hose into a container for drained fluid. Start the engine and, turning the steering wheel from lock to lock in both directions three or four times, drain the old fluid while adding new fluid. Repeat the operation until fresh fluid appears from the outlet hose.

Warning: Carefully monitor the fluid level in the reservoir and do not allow air to enter the power steering pump. This may damage the pump.

6. Install the tank in the reverse order of removal.

7. Add fluid to the level of the upper mark on the dipstick of the reservoir plug.

8. Bleed the power steering system as described here.

During operation, Chevrolet Niva power steering fluid can leak in various places, most often through hoses. As a result, the power steering oil level will drop.

Driving without fluid in the Chevrolet Niva's power steering puts you at risk of breaking the power steering pump, which costs a lot of money, since it will run dry. As a result, it will suffer serious damage and fail.

Bleeding the power steering system

To bleed the power steering system on a Niva, you need to set the steering wheel to the middle position and start the engine for a few seconds without turning the steering wheel. After this, you need to turn off the car and turn the steering wheel all the way in any direction.

Then the protective cap is removed from the special valve and, using a wrench, it is turned to bleed any remaining air from the system.

Then you need to turn the steering wheel in the other direction, leaving the air bleed valve open. An air plug and some liquid will come out of it, after which the valve must be closed. If necessary, the mixture is added to the power steering to the maximum mark. Then you need to start the engine and turn the wheel from side to side until it stops. This must be done until air bubbles stop escaping into the tank. If necessary, the mixture is topped up again to the required level.

Intensive use of the Chevrolet Niva makes the color of the power steering oil darker over time, often with a burning smell. This is a reason to think about replacing it.

Overheating of the oil often occurs when the steering wheel is held in the extreme position for a long time, until it boils; the pressure in this case is maximum.

You should also not leave your car parked for a long time with the steering wheel turned all the way.

Disconnect the hose through which the oil enters the return tank.

Changing the power steering fluid in a Niva Chevrolet

At the moment, almost all modern car models are equipped with power steering. It allows you to simplify wheelbase control and make it easier. This is especially true for a car like the Chevrolet Niva, which belongs to the SUV class. The Niva's mass is one and a half tons, and in off-road conditions it is required that the wheels react sharply to turning the steering wheel.

Also, the need to add fluid to the steering wheel on a Chevrolet Niva can be determined by its external condition. It is believed that the power steering is refilled once by the manufacturer and does not require replacement during further operation. But if there is damage to the steering rack, oil and dirt may enter the system.

As a result, traces of contamination can be seen in the expansion tank. Also, power steering fluid, like all fractional mixtures, can form a sediment of components over time, which affects its quality and requires replacement. In practice, it is necessary to change it every six years, regardless of its condition, since the temperature difference between winter and summer negatively affects its condition.

Structural elements of power steering

by wpadm August 11, 2016

From the above it is clear that the hydraulic booster is an important part of a modern car. The entire power steering complex consists of the main elements:

  1. Oil injection pump;
  2. Spool type distributor;
  3. Power cylinder;
  4. Reservoir with lid and oil filter;
  5. Power steering radiator;
  6. Connecting hoses;
  7. Tube systems with adapters.

The pump itself, which is rotated by the engine motor through the power steering belt, provides the entire system with oil, which constantly circulates through the pipes with the required pressure.

Driving oil through the system circuit is the main ability of the power steering pump. The main installation location is on the side of the engine, where there is a special power steering bracket.

The power steering drive may be the main reason for poor power steering performance. If the drive belt breaks, the entire system stops working. detect the moment when the power steering drive belt : kickback (reverse push) of the steering wheel.

It is especially noticeable when the car is moving from a standstill with the steering wheel turned. The power steering roller helps maintain constant tension on the drive belt . If the drive belt breaks, the power steering allows you to maintain control over the control of the machine using the spool.

Distributor - location, both on the shaft and with mounting on other elements of the steering mechanism. Its main task is to distribute the flow of working fluid between the power steering and the return flow to the power steering reservoir.

It is classified into two types - rotary and axial, according to the types of spool movement. Axial – makes translational movements. The rotary one rotates. This element is very sensitive to contamination of the working fluid in the system - dirty and poor-quality fluid will create problems in the operation of the distributor.

The power steering reservoir is a plastic container that contains the working fluid. Inside it there is a power steering filter, which pre-cleanses the poured oil from foreign particles.

The power steering cover is equipped with a built-in dipstick with marked marks, which can be used to determine the fluid level in the reservoir. If the level drops significantly, you should pay attention to the tightness of the connections of tubes, hoses, etc.

Power steering connecting there are several of them in the power steering system. They provide the connection of individual elements into one common system through which the working fluid is supplied.

They are divided into two types of hoses - high and low pressure. High pressure hoses provide oil flow to the pump, distributor and main cylinder. The waste fluid flows back into the tank through low pressure hoses.

double-acting power steering cylinder The power steering rack is integrated with the power cylinder and responds to the rotation of the steering column. helps improve durability and smooth operation .

Power steering gearbox - its joint work with the distributor ensures the flow of oil into the desired cavity of the cylinder or return excess back to the reservoir. The working fluid in the power steering system is special grade oil.

In addition to the operation of the entire system, it provides additional lubrication of all rubbing parts of the system.

Power steering radiator - cools the system oil during power steering operation. In addition to the listed components, various distributor designs may also contain additional parts:

To repair the power steering cylinder, you may need a power steering repair kit. It is unique for each car model and is selected individually. Periodic replacement (once every two years) of the working fluid will help increase the service life of individual power steering elements.

Main elements of the system

The design of the VAZ-2123 provides refueling tanks that ensure smooth functioning of the mechanisms.

The main elements of the system include the following filling containers:

  • fuel tank;
  • transmission housing;
  • power steering;
  • cooling system;
  • engine lubrication system;
  • axle and transfer case housings;
  • container for hydraulic drive of the brake system;
  • tanks for washer fluid;
  • containers for refilling the air conditioner.

The following is a table of fuel volumes for the Chevrolet Niva:

To improve the performance characteristics of an SUV, working fluids must be poured in quantities recommended by the developers of the Chevrolet Niva.

Fuel tank

All-wheel drive and increased cross-country ability of the Chevrolet Niva increase fuel consumption. Therefore, this AvtoVAZ model has a 58-liter fuel tank. It is located in the rear of the car. The fuel tank is made of high-strength steel and has a complex design.

Because gasoline tends to evaporate, excess pressure can build up inside the gas tank, increasing the risk of explosion. To reduce pressure, the designers of the VAZ-2123 provided an adsorber valve, with the help of which excess gasoline vapors are released.

The fuel tank housing has a stamping for the driveshaft channel, which divides the gas tank into two communicating reservoirs. Therefore, about 7 liters of fuel remains in the tank, which does not enter the fuel line. However, the design of the gas tank allows fuel to be filled under the neck, which allows you to fill up to 64 liters of fuel. This feature compensates for the unconsumable remaining gasoline.

Cooling system

When the car engine is running, the temperature of the exhaust gases reaches 2000 degrees. Due to the elevated temperature, the lubricant burns out. This leads to engine malfunctions and wear of parts. To avoid engine overheating, VAZ-2123 vehicles are equipped with a closed-type liquid cooling system, which consists of the following components:

  • radiator;
  • expansion tank;
  • fan;
  • water pump.

For cooling, antifreeze is used with the addition of additives that have anti-corrosion properties. The operating principle of the cooling system is based on the forced circulation of antifreeze through the cooling jacket around the engine cylinders.

The pump ensures uniform circulation of the coolant. After starting the engine, the pump begins to pump antifreeze through the small circuit of the cooling system. When the engine heats up, the thermostat activates, after which a large circuit opens. The expansion tank is needed to relieve excess pressure that occurs when the antifreeze heats up. Passing through the radiator, the liquid is cooled by a fan.

Engine lubrication system

Friction and high temperatures reduce the service life of the engine and the service life of the vehicle. To avoid premature wear of engine parts, it is necessary to monitor the oil level. In the Chevrolet Niva, the designers have developed a combined engine lubrication system. The crankshaft and camshaft bearings, pushrod tips and rocker arm bushings are pressure lubricated. The remaining parts are lubricated using the spray method.

Using an oil pump, oil from the crankcase through the oil receiver enters the filter housing. After cleaning, the lubricant is supplied to the oil line, from where it is supplied to the parts under pressure through inclined channels. The pressure at medium speeds in a working VAZ-2123 lubrication system is from 200 to 400 kPa. A decrease or increase in pressure indicates a system malfunction.

New structural elements

Car manufacturers, in order to reduce the pressure in the power steering system when the vehicle moves in a straight line, install an electronic control unit for the entire system.

At high speeds, such a system regulates oil pressure in such a way that driving the car becomes more informative and the driver always has time to react in time to the slightest change in the trajectory.

But the improvements do not end with the introduction of electrical oil pressure control. The mechanical power steering was replaced by an electric oil pump. The mechanical drive replaced the electric motor, which is capable of changing the rotation speed when the vehicle speed changes.

And the concept cars are already equipped with electric power steering instead of hydraulics.

Story

I have already said many times that I do not do tuning or modifications for the sake of the process. Only if there are problems. In this case, it all started with the “collective farmers” of AvtoVAZ. For a very long time, the plant installed German ZF power steering pumps on the assembly line, and then suddenly the Russian version came into use. As usual, the plant was not going to give any explanations, so I had to turn to another source, the manufacturer ZF. A technical seminar organized by this company was held in St. Petersburg, and I asked the German a question about this situation. Directly at the lecture (that is, the official position), the German specialist said that this is a trade secret. And during the lunch break, when I addressed him in German, he straightened up and said the following. Quote. Along with the supply of pumps, we gave a recommendation to AvtoVAZ on what SHOULD be poured into the system. At first, the plant filled it with an approximate analogue of the liquid that we recommended, and then suddenly it started pouring green Pentosin. The result was not long in coming - leaks and a humming sound when turning. But the funny thing is that all these “supposedly” warranty cases were transferred to the shoulders of ZF. The German said that we “butted heads” with the plant a little, did not get clear answers from the managers and management and simply stopped supplying this spare part. End of quote. Now we come to a simple conclusion: in order to get a working unit, as intended by the designers, we need to flush the system and fill it with what is recommended. The fluid is simple, good synthetic dextron, but along with it I recommend replacing the low pressure hoses.

rdoctor: Power steering, unlike electric power steering, dampens the transmission of impacts from the wheels to the steering wheel - when hitting a pothole at speed, the steering wheel will not be torn out of your hands. Actually, this is the main (and perhaps the only) plus of the power steering. The power steering uses a standard steering gearbox. With a booster, you will be spinning the wheels more often on a stationary car, which will shorten the life of the standard RR. The power steering comes with its own gearbox.

As for the rest, the EUR has only advantages. Price, ease of installation. And the fact that if the power steering malfunctions, you will simply get a standard steering wheel, and not a steering wheel that can barely be turned (although we have never heard of malfunctions in our power steering).

My Fora has power steering as standard. Satisfied.

But the question is... Does our Nivsky power steering change the force on the steering wheel depending on the speed, or not? I want the steering wheel to stiffen as the speed increases, and not remain weak. As far as I understand, the power steering monitors the speed (does it really load the steering wheel as it increases?) And the power steering? Is he just unloading? Or does it still track? (how does it track, by the way, if it does track?)

People, let me know who installed the Nivo EUR, how is it in terms of quality? I want to buy it, it’s cheaper than the Priorovsky one and the lock, the steering wheel and steering columns don’t need to be changed, everything is original. The only difference is that the Priorovsky one has height adjustment.

How does power steering work? Its main element is a pump, which, using a belt from the crankshaft, sucks in oil and pumps it into the distributor. The latter, in turn, monitors the force applied to the steering wheel and, using a torsion bar (follower device), helps turn the drive wheels. When moving in a straight line, the torsion bar does not twist, so the distributor channels are blocked and the oil drains back into the reservoir.

Power steering is most often useful when parking and turning, making the work of your hands three times easier. We can also say that the mechanism weakens the transmission of microshocks from the road surface to the steering. The mechanism is also useful in case of a sharp drop in tire pressure. The disadvantages of power steering include the fact that it interferes with “feeling the car”, so designers need to achieve a compromise between informativeness and tightness of the steering wheel.

Foreign manufacturers conduct a lot of research in order to make the hydraulic booster light at low speeds and elastic at high speeds. To do this, German hydraulic boosters from ZF are equipped with pressure modulators, which limit the oil pressure in the operating circuit as speed increases. In addition, circuits with power steering driven by an electric motor are acceptable, which makes it possible to change the pump performance in accordance with the rotation of the electric drive. Sometimes the gear ratio is also changed.
