5.1.6. Cars with the 8-cylinder petrol engine and a chain drive

Conditions for check
Poliklinovoj belt / the tension semi wedge a belt should be in norm.
Highway hoses / should not have crises and should not be pressed.

Check

Fig. 5.2. Clips for hoses


Clamp soaking up and drain lines clips for hoses till the diameter of 25 mm (fig. 5.2).
Remove a noise isolation.
For check of a pressure of the pump the pressure head hose from the pump does not act in film. Connection of the device is made for hydraulic booster check on connection in the left bottom part of a motor compartment.
Under a separation place substitute the pallet that in it hydraulic oil followed.

Fig. 5.5. Connection of a hose of hydrosystem


Separate connection (fig. 5.5).

Fig. 5.6. The scheme of installation of the device for hydraulic booster check: 1 – a pressure head hose; 2 – an adapter; 3 – a pressure head hose; 4 – a hose from the complete set of adapters; 5 – a manometre


Establish the device for hydraulic booster check, as is shown in drawing 5.6.
Wind a hose of the device for hydraulic booster check on a pressure head hose.
Clips for hoses till the diameter of 25 mm remove.

Fig. 5.7. Position of the lever of a manometre


Watch that the lever on a manometre was in position 2 (fig. 5.7).
Start the engine, without pressing a gas pedal.
10 times turn a steering wheel from an emphasis against the stop.
Stop the engine and if necessary add in a tank oil for hydraulic systems.

THE NOTE
In order to avoid damage of the pump of the hydraulic booster pay attention to the following: запорный the manometre valve at this check cannot be closed more, than on 10 with.

Start the engine, without pressing gas, and leave it to idle.
Pressure of the pump read out on single turns directly after engine start (if necessary to involve the second technician).
As during check pressure falls, consider the maximum shown pressure follows
After that check up pressure head pressure.

Fig. 5.8. Crane closing


Start the engine and at single turns of the engine close the valve of poses. 1, consider pressure (the lever should look aside from a pressure head hose) (fig. 5.8).
Duration of measurement no more than 10 with.
The set pressure: 123–130 bar
If the rating value is not reached, крыльчатый it is necessary to replace the pump.
Switch off the engine.
Remove the device for hydraulic booster check.
Collect screw connection of pressure head hoses, 40 Нм
Check up level of a working liquid in hydraulic system.
Establish a noise isolation.
