DISTRIBUTION BELT TENSIONING
Cold engine (ambient temperature).
Mount the new belt, the distribution being at setting point (P.M.S.).
Place the tensioning cam and tighten t he distri bution belt by means of t he MOT 1135-01
device.
Block the tensionin g cam.
P lace the reading head of the MOT 1505 device in the measuring area ( at a distance of 5…
10 mm from the belt); Any of the two captors may be used on the understanding that not both of
them are simultaneou sly in front of the belt.
Make the distribution belt vibrating ( the measurement is validated by a ”bip” of the device).
Tighten the belt, by acting upon the tensioning cam, until obtaining a value within the range
210…275 Hz.
Block the tightener and tighten its nut at the required moment of 3 daNm.
Rotate 5 and a half turns the crankshaft.
Unscrew the cam nut.
Tighten again the belt until obtaining a value between 145 and 185 Hz.
Obligatory tighten the tensioning cam nut at 5 daNm.
NOTE
If the value is higher than 275 Hz, the distribution belt is to be replaced with a new one.

For the values checking of the front axle angles, consequently the rear axle angles, the vehicle
must:
- to be placed with the wheels on the rotating plates ( of the bench ) being in horizontal plane;
- to ensure its braking;
- to check its suspension for vehicle setting at its free height;
- to compress its front axle at half loading ( by means of the compressing device DIR 500);
- to check its suspension for vehicle setting at its free position;
- steering brought at middle point and the steering box blocked in this position;
These op erations are followed by the optical device attachment on the vehicle, observing the
instructions of the steering angles checking bench manufacturer.
