Can lead the following reasons to leakages of steering transfer and the pump of the amplifier of steering:

– the tank is overflowed with liquid;

– aeration and pouring out of liquid;

– unreliable connection of hoses.

       PREVENTION

• Precisely define the place of leak.

• The power shaft and adjusting consolidations are closely to each other, and can be not clear, leak in system where exactly.

• The point from which liquid follows optional is a point where in system there is a leak.

• Determine the term of carrying out maintenance.

After dismantling clear area of leak.

Establish new consolidations.

Check the condensing surfaces of elements for existence of damages.

Tighten bolts the required moments.

Also following reasons resulting in malfunctions in the amplifier of steering board are possible:

– a liquid effluence on a garage floor;

– existence of noticeable leak of liquid in steering transfer or pump of the amplifier of steering;

– the rolling noise, especially at the parking or during the operation of the cold engine;

– loss of power of the amplifier of steering at the parking;

– at turn of a steering wheel it is necessary to use the considerable efforts.

At elimination of such malfunctions check hydraulic system of the amplifier of steering for existence of external leaks.

The purpose of this operation is exact definition of the place of leak. It is the most difficult to isolate leaks like infiltration. To define the place of leakages like infiltration, use the following method.

At the switched-off engine dry wipe all hydraulic system of the amplifier of steering.

1. Check liquid level in a pump tank. If necessary add liquid.

2. Launch the engine and ask the assistant to turn several times a steering wheel from an emphasis against the stop.

       PREVENTION

You do not hold the steering wheel turned against the stop during any period. It can damage a shaft of the pump of the amplifier of steering.

Fig. 13.45. Diagnostics of leakages of steering transfer: And – if there is a leak between shaft and a short axis, replace the valve assembled, a dustproof sealing ring and a sealing ring; In – tighten a connecting nut the moment of 27 N • m. If leak of liquid is not eliminated, replace a sealing ring. If leak is caused by damage of a carving, restore a nut or replace a hose. If the casing carving is damaged, replace it; With – tighten a connecting nut the moment of 18 N • m. If leak of liquid is not eliminated, replace both sealing rings. If leak is caused by damage of a carving, restore a nut or replace the pipeline. If the casing carving is damaged, replace it; D – if leak is observed from a driver's seat, replace consolidations of a shaft of the leading gear wheel; Е – if leak is observed at an end face of the cylinder and liquid follows a stream when performing the left turn, replace consolidation of the directing piston draft and a sealing ring; F – if leak is observed at an end face from the forward passenger, it is necessary to remove a crossing point and to replace a sealing ring. If leak is still observed, tighten a connecting nut the moment of 18 N • m

Fig. 13.46. Diagnostics of leakages of the pump of the amplifier of steering of a series N: And – replace a sealing ring; In – tighten a connecting nut the moment of 18 N • m. If leak is still observed, replace a sealing ring; With – tighten a stopper the moment of 75 N • m. If leak is still observed, replace a sealing ring; D – if leak is observed in a point 1, grease connection of a pipe and a casing with Loktit solution and Loktit-290 lubricant. If leak is observed in a point 2, replace a pipe and if in a point 3 – replace a hose or a clip; Е – replace consolidation of a power shaft. Make sure that the power shaft pure and is not damaged by pointed corrosion

3. Find the exact place of leak and eliminate it. Places of possible leaks and methods of their elimination are given in drawings 13.45, 13.46.

The Manzhetny consolidations condensing the rotating shaft demand special maintenance. Consolidations of this type are used in steering transfer and on driving to a pump shaft.

When replacing consolidation perform the following operations:

– carefully check and clear the condensed surfaces;

– replace a shaft only in case of detection of strong wear;

– if wear of a contact surface of manzhetny consolidation is insignificant, smooth out a surface a fine-grained emery paper;

– replace a shaft only in case of impossibility of an exception of leak at the first cleaning with a fine-grained emery paper.

Fig. 13.47. The manometer for check of hydraulic system of the amplifier of steering

Check of hydraulic system of the amplifier of steering can be conducted independently with use of the manometer as it is described below (fig. 13.47).

They can be also carried out by means of the analyzer of power of steering transfer which measures both the stream speed, and pressure.

1. Establish a pressure head hose on the pump. By means of a small container collect liquid which can flow out.

2. Connect a free pressure head hose to the pump.

3. Connect the manometer between the line leading to steering transfer and the line conducting to the pump of the amplifier of steering.

4. Open the valve on the manometer.

5. Launch the engine. Allow system to reach working temperature, then check the level of liquid and, if necessary, add liquid.

6. Completely close the valve 3 times and write down pressure at each closing of the valve.

Pressure created by the pump, 552 - 862 kPa. If pressure exceeds 1380 kPa, check hoses for existence a perezhatiya. Check correctness of assembly of the dish-shaped valve on steering transfer.

       PREVENTION

Do not leave the valve closed more than on 5 with as damage of the pump is possible.

Pressure created by the pump (at the closed valve) not less than 6895 kPa. Pressure created by the pump (at the closed valve – pumps with standard technological properties): not less than 8619 kPa.

If values of pressure are rather high and the difference between them does not exceed 345 kPa, the pump functions normally. If values of pressure are rather high, but the difference between them exceeds 345 kPa, perform the following operations:

– on the control valve remove agnails by means of a fine-grained emery paper;

– wash out system;

– sort and clear the pump and steering transfer.

If values of pressure are lower than 6895 kPa or lower than 8619 kPa for pumps with standard technological properties, replace the control valve and carry out a repeated inspection. If values of pressure still low, replace a rotor and blades.

7. If values of pressure created by the pump correspond to demanded, leave the valve open and turn a steering wheel from an emphasis against the stop and write down the maximum values of pressure. If pressure on both extreme provisions not to the equally maximum value of pressure created by the pump (at the closed valve), which is written down in the previous step is available internal leakage of steering transfer.

8. Switch off the engine.

9. Remove the test manometer.

10. Repeatedly connect a pressure head hose.

11. Check liquid level.

1. Cut off a clip, the fixing returnable hose conducting from steering transfer to the returnable line from the pump and throw out a clip.

2. Disconnect a returnable hose from the returnable line.

3. Smoothly bring the end of a sleeve without trailer fittings and a returnable pipe assembled over the end of the returnable line out of the pump and fix by a clip.

6. Connect a pressure head hose of the required length and tighten a connecting nut the moment of 27 N • m.

7. Connect other end of a pressure head hose to steering transfer assembled and tighten a connecting nut the moment of 27 N • m.

8. Launch the engine, leave it to idle about 10 with, then switch off it.

9. Check the level of working liquid of the amplifier of steering and if necessary bring to norm.

10. Launch the engine, turn a shaft of steering transfer on a whole revolution in each direction and hold about 5 pages at each emphasis.

11. Check for possible existence of points where there are leaks, and if necessary, repair them.
