SPEEDOMETER
An E.E.C. decree of 25 June 1976, regulates the speed displayed by the speedmeter in relation to the actual speed travelled.
This decree stipulates:
- The speed indicated by a speedometer must never be lower than the actual vehicle speed.
- Between the speed displayed «SD»and the speed travelled «ST», there must always be the following relationship:
ST < SD < 1.10 ST + 4 Kph
Example:For an actual speed of 100 Kphthe speed displayed by the speedometer may be between 100and 114 Kph.
The speed indicated by the speedometer may be influenced by:
- The speedometer.
- The tyres fitted to the vehicle.
- The final drive ratio.
- The speedometer drive ratio.
Any of these components can be checked without removing them from the vehicle
(see information note N° 78-85 TT of 19 October 1978).
NOTE:Before replacing the speedometer, check the conformity of the following points:
- The tyres fitted to the vehicle.
- The gearbox final drive ratio.
- The speedometer drive ratio.

STEERING
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.
