What is the correct step to replace the steering machine of the car?

Disassembly of the car steering machine:

1. Clean the servo carefully.

and its related components, especially tubing.

2.Drain the steering system.

1) Set the front axle.

2) Open the fuel tank cap, unscrew the servo drain bolt or loosen the servo oil outlet, and let the engine idle for a short time (no more than 10 seconds).

Running, repeatedly put the steering wheel.

Hit to the limit draining the residual oil in the pump and tank.

3) Add 2 to 3 liters of clean hydraulic oil to the tank.

Flush the line and turn the steering wheel to the limit position at both ends at the same time to flush the buildup in the oil circuit and drain the oil from the oil circuit. Oil outlet (the engine can idle for a short period of time, no more than 10 seconds).

4) Tighten the servo oil drain bolt or connect the servo oil outlet.

5) Remove the filter from the tank, clean it and reinstall it.

Car Steering Machine Installation:

1. In order to avoid debris from entering the steering oil circuit and causing failure, do not remove the blockage of the oil inlet and outlet of the steering gear before connecting the oil pipe, and carefully clean the oil pipe joint.

2.Attach the vertical steering arm to the steering gear. The spline between the vertical arm and the output shaft of the steering gear.

No oil or foreign matter is allowed on it. The marking line on the vertical arm must be aligned with the marking line on the output axis of the servo.

3. Fix the boom and tighten the fixing nut according to the specified torque.

4. Tighten the lock nut according to the specified torque and hit the rivet (anti-loosening pit).

For the inner tie rod of this steering machine, you need to remove the dust cover and clip of the servo, and then move the dust cover outward, and then kill the direction while thinking about the direction, and then you can remove the servo. Tie rod screws. Simple.

Airbags on the steering wheel.

There is a hole in the back. There is a snap ring inside. It can be inserted with lowercase letters, and the circlip can be pried open.

Pull out the airbag and remove the steering wheel screws. Tighten the bolts on the bottom. In addition to changing the shrapnel, the servo is generally useless to disassemble. The linkage gear must be aligned, and the linkage pin is the easiest to stuck.

This step is to remove the steering machine that has been damaged before, and then replace it with a new steering machine, connect the circuit inside, and finally start the vehicle to see if it can be used normally.

The first thing is to turn off the car, then park the car in a relatively safe place, then open the hood, find the problem, and then replace it, you can go directly to the repair shop to replace it.

The car should be driven to the repair shop and then let a professional master repair it, because you don't know how to replace it, you can only find a professional master.

The steering machine uses an electric pump to complete the steering. Its working state is the most ideal state calculated by the electronic control unit, that is, the ECU according to the vehicle's driving speed, steering angle and other signals. The main structure of vehicle steering is composed of fuel storage tank, booster pump, electric pump, steering gear, power steering sensor, etc.

Many steering system failures in heavy-duty trucks are caused by a damaged steering gear, which needs to be replaced. When it comes to replacing a steering machine, many repair shops don't maintain it strictly according to the specifications. Some small repair shops only realize the replacement of exhaust, resulting in heavy steering, insufficient steering angle, inconsistent left and right turning times in the later stage and other problems, today we will talk about the correct maintenance and replacement method of the steering gear.

When installing the steering machine, in order to avoid debris entering the steering oil circuit and causing failure, do not remove the blockage at the inlet and outlet of the steering gear before connecting the oil pipe, and carefully clean the oil pipe joint.

Attach the steering arm to the steering machine. There shall be no oil or foreign matter on the steering arm spline and the output shaft of the steering machine. The scribing on the steering sag arm must be aligned with the scribing on the steering output shaft.

After the steering arm is connected to the steering machine, in principle, the vertical arm is not allowed to rotate. If it is necessary to rotate the steering sag arm during installation for ease of installation or for other reasons, it should be ensured that the swing angle of the steering sag arm relative to the initial position is less than 20 degrees. After installation, the steering sag arm must be turned to the initial position.

When the sheath is damaged, water, dust and sand can enter the steering gear through the damaged parts, damaging the grease film of the rack, causing corrosion and abnormal wear inside the steering gear. If the water and sand inside are not treated immediately, the steering gear will be scrapped in a short time. The condition of the dust jacket should be checked at least once a month.

If the sheath is damaged, it must be replaced immediately, and the steering gear should be fully inspected and serviced before replacement. The middle clearance of the steering machine will gradually increase during use. If the steering wheel idles more than 15 degrees from side to side, the steering machine must be checked.

If the rack is abnormally worn, the steering assembly must be replaced; If there is no abnormal wear, but the gap is too large, it can be adjusted.

When replacing the steering machine, it must go through very accurate debugging, and it is best to go to the 4S shop, which is not available in ordinary repair shops. After replacing the steering gear of the car, you should choose some relatively flat roads to walk, do not choose some potholes and uneven roads, and also look at the state of the protective covers on both sides of the steering machine, and also do a good job of regular protection measures.

What should be paid attention to should be to choose a better direction machine, and to choose the kind of direction machine with better quality and perfect in all aspects.

It should be noted that the circuit connection inside must be ensured when replacing, and try to choose the direction of the original factory when replacing it to be able to operate normally.

Generally, after the assembly is completed, it is necessary to undergo very precise debugging on a professional test bench. Such technical and experimental conditions are not available in general repair shops. If the oil seal of the steering control valve is damaged and leaking, it is recommended not to repair it and directly replace the new Danfan assembly.

If there are too large scratches, strains, etc., or the gap between the two is too large, even if the repair kit is replaced with a new one, there may be no oil leakage for the time being, but the use time will not be very long, in this case, it is recommended to replace the assembly. If the total mold is particularly expensive, the cylinder and piston rod can also be repaired and then assembled by electroplating, brush plating, etc., which can generally be used for a long time.

The failure of many steering systems of heavy trucks is caused by the damage of the steering machine, and the steering machine needs to be replaced, and many repair shops do not strictly follow the specifications for maintenance when replacing the steering machine, and some small repair shops only do "replace the exhaust", resulting in various problems such as heavy steering in the later stage, insufficient steering angle, and inconsistent left and right turns. So how to replace the car steering machine if it is broken? There are screws or holes at the bottom of the small side cover, which can be removed by directly removing the airbag; The steering gear, commonly known as the steering gear, is the most important component of the steering function of the car, and it is also an important guarantee for the safety of the car driver; Steering gear is widely used.

According to its different structural characteristics, it can be divided into rack and pinion steering gear, recirculating ball steering gear, worm gear steering gear and worm pin steering gear.

<> the repair of the oil leak of the steering gear is not difficult, but neither the garage nor the 4S shop can repair it. It is advisable to find a mechanical fitter to fix it. They are very knowledgeable about mechanical repairs and do not need to spend a lot of money to do it.

Oil spill maintenance for the steering gear is relatively simple. If the oil seal is damaged, it can be replaced; If the gasket is damaged, it can be replaced.

The most complicated case is the wear of the steering shaft, which can be cold repaired [cold welding of the metal and then machining on a grinder]. The situation you describe is almost the same as replacing the oil seal. This cannot be changed.

In your case, you can sue or ask for a replacement steering wheel when you hit it again. But one bit of trouble is that the insurance company will say that you have an old injury to your steering machine and there is no compensation or deduction!

If you can repair it at an old repair shop, it is best to go to the after-sales service. In general, there are very few steering gear parts in the repair shop; If the steering gear fails, it may be difficult to steer, the steering power failure (i.e., no power assist, excessive steering), and the steering gear is stuck and cannot be turned (the direction cannot be turned directly, and the balance wax is stuck), which indirectly leads to abnormal tire wear; If the steering machine is broken, it must be repaired. It's better to fix it.

If it cannot be repaired, the assembly is simply replaced. It is better to replace the original parts, which is ***. This situation has a direct impact on driving safety.

Familiar with mechanical repairs. It doesn't cost much to complete it. Oil spill maintenance for the steering gear is relatively simple.

If the oil seal is damaged, it can be replaced; If the gasket is damaged, it can be replaced. The most complicated case is the wear of the steering shaft, which can be cold repaired [cold welding of the metal and then machining on a grinder]. The situation you describe is almost the same as replacing the oil seal.

Carefully judge and then replace. Many of today's repairmen will not judge the fault, and will only blindly replace the parts. Why kill the direction? You must know that no matter what car kills the direction, the engine will automatically cut off the oil. "Yes

Pay attention to the run-in, don't kill the direction, everything else can be as usual.

First, the disassembly of the steering machine.

1.Carefully clean the steering gear and its related parts, especially the oil pipes.

2.Steering system drains.

1) Prop up the front axle.

2) Open the oil tank cover, unscrew the oil drain bolt of the steering machine or loosen the oil outlet of the steering machine, idle the ** motor for a short time (no more than 10 seconds), and repeatedly turn the steering wheel to the limit position at both ends to release the residual oil in the oil pump and oil tank.

3) Add another 2 3 liters of clean hydraulic oil to the oil tank to flush the line, and at the same time turn the steering wheel to the limit position at both ends, so that the attachments in the oil circuit are flushed clean, and the oil is discharged from the oil outlet (the engine can idle for a short time for no more than 10 seconds).

4) Tighten the oil drain bolt of the steering machine or connect the oil outlet of the steering machine.

5) Remove the filter element from the oil tank, clean it and put it back in.

Note: When draining oil, the residual oil of the steering machine, oil pump, oil tank, oil pipe and booster cylinder should be released, and it should be confirmed that the entire hydraulic system is thoroughly clean and free of any impurities.

3.Make sure the steering axle wheels are in a straight line.

4.Disassemble the steering tubing and close the tubing joint to prevent dirt from entering.

5.Loosen the lock nut.

6.Remove the drooping arm with a special tool.

7.For adjustable steering columns, turn the steering column to the highest. Hang the steering axle with a suitable rope strap through the steering shaft cross gap.

8.Loosen the connecting bolts of the steering shaft from the steering machine and separate it.

9.Remove the steering machine fixing bolts and remove the steering machine.

10.The old steering machine is cleaned, can not be bumped, packed in good condition, and put into storage.

Second, the installation of the steering machine.

1.In order to avoid debris entering the steering oil circuit and causing failure, do not remove the blockage of the steering machine inlet and outlet before connecting the oil pipe, and carefully clean the oil pipe joint.

2.Install the steering arm on the steering machine, no oil or foreign matter is allowed on the spline of the vertical arm and the output shaft of the steering machine, and the engraved lines on the vertical arm must be aligned with the engraved lines on the output shaft of the steering machine.

3.Make the hanging arm fixed, and lock the fixing nut with the specified torque.

4.Tighten the locknut and rivet (anti-loosening pit) according to the specified torque

Hello, the steering machine replacement process, according to the structure of our vehicle to repair, first of all, the door to see whether it is a sedan or a truck, because each kind of tomato disassembly process is different, I hope mine can help you.

Yes, if the steering machine is broken, it must be repaired, it is best to repair it, and it is best to replace the assembly parts directly if it cannot be repaired, and it is best to replace the original parts, which is guaranteed, which directly affects driving safety.

If the steering machine is broken, it may be difficult to steer, the steering power will fail (that is, there is no power assist, and the steering is too heavy when steering), the steering machine will be stuck and unable to turn (the direction cannot be turned directly, and it will be stuck), and the indirect will also lead to abnormal tire wear.

Yes, it is generally the cause of oil leakage in the steering machine, and more than 90% of it is caused by the aging of seals (oil seals)! Seals (oil seals) harden over time, that is, they lose their plasticizer over time. This process is exacerbated by the constant alternating operating temperatures of warm and cold.

As a result of this poor process, the seals first begin to shrink, then harden, and finally even break, and oil leaks are inevitable.

The current direction of the car is generally not able to be repaired, and under normal circumstances, there is a problem to directly replace this assembly.

Ask the question about the electronic power steering.

Answer: I know that it is electronic power steering, and now most models are electronic power steering, which is generally not maintained. It is difficult to buy this separate accessory for this repair after this disassembly, and then another one is after the repair, this will not last long, and there may be problems.

The steering machine of the car, the general minor fault can be repaired, if it is serious, it is recommended to replace it directly.

Hello! If the problem is small, it can generally be repaired, and if it is more serious, it can only be replaced with new parts.

The steering machine can be repaired, but you have to go to a professional repair of the steering machine to repair the shop, which can be repaired and the same as new, mine is repaired for 5 years and has been very good.
