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.

IMPERATIVE: Use only new brake brake fluid that is not emulsified, avoid any
ingress of impurities into the hydraulic circuit.
IMPERATIVE: Do not use automatic bleeding equipment
(risk of the brake fluid
emulsifying in the hydraulic circuit).
Couple a transparent tube (5)on the bleed screw, at «c».
Submerge the end of the tube (5)in the recipient containing the brake fluid, located
below the level of the clutch slave cylinder.
Use the transparent tube (5) to act as a siphon, at «b».
WARNING: the end of the tube (5) must be submerged in the brake fluid.
Open the bleed screw at «c».
