Precautions to be taken.
Work with care to avoid entry of polluting particles into the circuit.
NOTE:The correct operation of the system requires perfect cleanliness of the fluid and of the
hydraulic components.
Check:
- The level of the power steering fluid.
- The condition of the piping and unions.
Using the tools.
Prepare the checking assembly [1], [2], [3], [4], [5], [6]and [7].
Attach the tool [1].
Remove the front RH wheel, the splash-shield and the screen wash reservoir.

CHECKING THE POWER STEERING ASSISTANCE PRESSURE
Preliminary operation.
Move aside the high pressure pipe (1).
Do up:
- The union [6]on the power steering electropump.
- The union [7]on the high pressure pipe (1).
- Tighten all the unions.
Fill the power steering reservoir 10 mmabove the max. level.
IMPERATIVE: Use new power steering fluid for both filling and topping-up the circuit.
Open the tap [5].
Start the engine and allow it to run for 5 seconds.
Stop the engine.
Move the steering several timesin each direction.
Check the steering fluid level and make sure that there are no leaks.
Checking the electropump pressure.
Start the engine.
Close the tap [5]for 5 seconds.
Open the tap [5].
Stop the engine.
At accelerated idle
(1200 to 1500rpm), the pressure should be 105 ± 5 bars.
If the electropump pressure is correct, check the valve sealing.

CHECKING THE POWER STEERING ASSISTANCE PRESSURE
Checking the valve sealing.
Remove the under-engine shield.
Move aside the heat shield from the steering mechanism.
Slacken the unions (2)on the power steering ram.
Uncouple the two supply pipes (3)from the distributor valve and move them aside.
Fit on the distributor valve the two plugs [8], tighten to 0,8 m.daN.
Move the steering slowly from lock to lock, to drain the ram.
Top up the level of the power steering fluid.
Open the tap [5].
Stop the engine.
Maintain the engine speed at accelerated idle.
Hold the wheels on full lock, first on one side then on the other.
The pressure should adjust to 105 ± 5 bars.
The pressure is correct: replace the steering mechanism.
The pressure is lower than the values above: replace the distributor valve.
Couple the two supply pipes (3)on the distributor valve; tighten to 0,8 m.daN.
Retighten the unions (2)on the power steering ram; tighten to 0,8 m.daN.
Remove the union [7]on the high pressure pipe (1)and the union [6]on the power steering
electropump.
Refit:
- the high pressure pipe (1); tighten to 2 ± 0,2 m.daN.
- the screen wash reservoir, the front RH splash-shield and the front RH wheel.

CHECKING THE POWER STEERING ASSISTANCE PRESSURE
Fill the power steering reservoir to the max.mark «a»on the cap (4).
Engine stopped, move the steering slowly from lock to lock, in both directions approx. ten times.
Top up the fluid to the max. mark «a»on the cap (4).
Run the engine at idle for 3 minutes, without any action on the steering wheel.
Move the steering from lock to lock, until there is no longer any tight spot.
Top up the level if it again goes down.
Bleed the circuit by moving the steering several timesin each direction.
Top up the level if it again goes down.
IMPERATIVE: Use new power steering fluid for both filling and topping-up the circuit.
