3 - BELT TENSION

3 - 1 - TENSION AT THE ALTERNATOR

Slacken the bolts (3) .

Position the belt tension measuring equipment [1] .

Turn the bolt (4) to obtain the recommended value .

Tighten the bolts (3) to 3.7 daN.m .

Remove the tool [1] .

Turn the engine 3 revolutions .

Check the tension - Adjust the value (if necessary) .

Tension values :

- toothed trapezoid belt : 81 SEEM units (67 SEEM units when re-used)
- polyvee belt (6 Vs) : 120 SEEM units (90 SEEM units when re-used)

3 - 2 - TENSION USING THE RACK TENSIONER

Slacken the nut (5) .

On the run (A), position the belt tensioning equipment [1] .

Turn the bolt (6) to raise or lower the tensioner roller and obtain the recommended tension value .

Maintain the tensioner roller in this position .

Tighten the nut (5) to 4.5 da.Nm .

Remove the tool [1] .

Turn the engine 3 revolutions .

Check the tension - Adjust the value (if necessary) .

Tension values : 138 SEEM units (103 SEEM units when re-used) .

3 - 3 - TENSION USING THE DYNAMIC TENSIONER

Turn the square bolt (7) to compress the tension spring until the tool [2] allows immobilisation through the hole (8) .

Fit the belt observing the correct routing .

Compress the spring to release the setting rod .

Slowly release the tensioner .

WARNING : when positioning the belt, fit the tensioner roller last .

IMPERATIVE : tightening torque of bolt (9) : 5.7 da.Nm .
