NOTE: If there is no fluid in the reservoir, check the entire steering system for leaks. In case of leaks in the area of pipeline connections, first of all check the pipelines and their connections for tightness, if necessary, tighten and wipe dry. The pumps supplied by the manufacturer are not filled with oil. Therefore, before installation, be sure to fill the pump with hydraulic oil 6 002 000 and turn it by hand, otherwise running noises or damage to the pump may occur.
Vane pump pressure test
Remove the engine noise shield.
Clamp suction hose 1 with hose clamp 3094 (pic. 5.17).
Unscrew the pressure line from the pump 2.
Install the adapters as shown in figure 5.18.
Remove the hose clamp 3094 from the suction line Make sure that the lever on the pressure gauge is in position 2 (pic. 5.19).
Start the engine and, if necessary, add hydraulic oil to the reservoir.
Turn the steering wheel from lock to lock about 10 times.
Then check the pump head. To carry out the test, the system must be leak-tight. Hoses and pipes must not be kinked or pinched.
With the engine idling, close the shut-off valve for no more than 5 s (position 1) and count the pressure (pic. 5.20).
Nominal pressure: 110-120 bar.
If the value is less than the nominal value, replace the vane pump.
Remove pressure gauge and adapters.
Bleed the steering system.
Check the hydraulic oil level and top up if necessary.
Check the steering system for leaks.
