THE GENERAL DATA

THE REASON
WAY OF ELIMINATION
From outside the steering mechanism hissing is listened
The noise accompanying normal work of a steering drive are supposed. Hissing is the most typical sound which is well listened at parking. This sound is not a consequence of malfunction of the steering mechanism and can be published, when the wheel turns in extreme position or at slow rotation of a wheel at car parking
Weak hissing is supposed. If hissing moderated it is not necessary to change the valve. Valve replacement as a rule does not lead to elimination of a hissing sound. Examine places round rivets elastic муфты. The steering shaft and a gear wheel should be correctly combined, that elastic муфта rotated without deformations at wheel turn. At any contact of metal details through elastic муфту in salon the hissing sound will be transmitted.
From outside the steering mechanism deaf knocks (reminding clicks) are listened
Easing of fastening of steering transfer
To tighten connections.
Easing of steering draughts
To check up a condition of tips of draughts, if necessary to replace.
The hydrodrive tube touches surrounding details
To expose a tube, it is forbidden to turn in.
Shaft easing сошки at turn from average position (at turns the weak knocks connected with small increase люфта of a shaft concerning average position are supposed that is provided by a design)
It is forbidden to regulate the steering mechanism and to reduce backlashes against norm for the purpose of easing of such knocks. Люфт a shaft сошки, exceeding norm, it is eliminated by adjustment of the steering mechanism.
Easing сошки on a shaft
To tighten a nut сошки with the set moment.
Sharp sound at turn or at return of a wheel to a starting position
Damage of a sealing ring гасителя fluctuations
To replace a ring.
The wheel does not come back in a starting position
Pressure in tyres differs from norm
To restore pressure.
Absence of greasing in details of a forward suspension bracket
To grease draughts and tips of draughts.
Задевание a flange муфты for заглушку the adjusting screw of the steering mechanism
To weaken pulling together bolt and to rearrange муфту.
Wrong combination of the steering mechanism with a steering column
To eliminate.
Infringement of corners of installation of wheels
To check up and adjust corners of installation of wheels.
Jamming of steering draught
To replace hinges of tips of draughts.
Jamming of spherical hinges of levers of a suspension bracket
To replace spherical hinges.
Задевание a wheel for the case
To amend wheel situation.
Bearings of a steering shaft are drawn or taken
To replace bearings.
Залипание or a contamination of a cylindrical zolotnik
To clear or replace a zolotnik.
Wrong adjustment of the steering mechanism
To remove the steering mechanism and to adjust.
The return hose of the hydraulic booster is pressed
To replace a hose.
The car withdraws aside (to check up at two arrivals in opposite directions to exclude influence of a wind and a road covering)
Infringement of corners of installation of wheels
To check up and adjust corners of installation of wheels.
Disbalance of the valve of the steering mechanism (in this case the wheel turns easily in a direction of leaving of the car, and in an opposite direction rotates under the influence of normal or a little большего efforts)
To replace the valve.
At fast turn of a wheel in both parties instant resistance is felt
Low level of a liquid
To restore level.
Проскальзывание a belt
To adjust a tension or to replace a belt.
Strong internal leak
To check up pressure upon a pump exit.
Wheel twitching at turn on the working engine, especially during parking with working engine
Low level of a liquid
To restore level.
Belt easing
To adjust a tension.
Задевание steering draught for the oil pallet
To eliminate.
Insufficient pressure of the pump
To check up pressure, if necessary to replace редукционный the valve.
Залипание the control valve
To check up a valve condition, if necessary to replace.
Raised люфт on a steering wheel
Air hit in a hydrodrive
To add a liquid and to remove air wheel turn. To check up an inhaling of unions.
Easing of fastening of the steering mechanism
To tighten connections динамометрическим a key.
Deterioration of tips of steering draughts
To replace.
Deterioration тарельчатого the valve
To replace.
Insufficient preliminary tightness of the persistent bearing at adjustment
To remove the steering mechanism and to adjust.
Raised люфт in gearing of gear wheels of the steering mechanism
To remove the steering mechanism and to adjust.
The complicated rotation of a wheel, strengthening of a steering drive on wheels is not felt
Belt easing
To adjust a tension.
Low level of a liquid (at falling of level of a liquid noise from the pump increase)
To restore level.
Wrong combination of the steering mechanism with a steering column
To eliminate.
Задевание a flange муфты for заглушку the adjusting screw of the steering mechanism
To weaken pulling together bolt and to rearrange муфту.
Low pressure in tyres
To restore pressure.
Liquid foaming, level falling, low pressure of the pump
Air hit, loss of a liquid because of leak in the pump
To find leaks and to eliminate. To remove air. Air gets a hydrodrive under operating conditions at very low temperature, when level of a liquid below norm. If level normal, but a liquid foams, remove the pump and disconnect a tank. Check up a condition of the case and заглушки. At detection of cracks the pump replace.
Weak effort from the pump гидроусидителя
The control valve is faulty
To clear the valve or to replace.
Warp of a press plate concerning a cam
To eliminate.
Weak effort from the steering mechanism
Losses of pressure because of deterioration of a piston ring or deterioration of the cylinder
To disassemble and check up a ring and cylinder condition.
Leak of rings of the valve and valve epiploon
To remove, disassemble and replace consolidations.
Chirping noise from the pump
Belt easing
To adjust a tension.
The squealing sound proceeds from a belt (it is well listened at wheel turn against the stop or at long parking with the working engine)
Belt easing
To adjust a tension.
Deaf sound of low tone from the pump
The raised return pressure in hoses or the steering mechanism, caused пережатием hoses
To eliminate пережатие, if necessary to replace details.
Deaf sound of low tone (it is distinctly listened at long parking with the working engine)
Teases on a press plate, a persistent plate or a rotor
To replace details and to wash out system.
Deterioration of a cam
To replace the worn out details.
Scratches in the pump
Low level of a liquid
To restore level.
Air hit. Not tight connection of hoses
To tighten unions with the set moment. To remove air, rotating a wheel in both parties against the stop.
