7.9.6 V-belt
Checking the condition of the V-belt
Check or tension V-belts only when the
engine is turned off.
Risk of injury!
•
Check the entire V-belt for damage (visual
inspection).
Replace damaged or worn V-belts
immediately.
Checking V-belt tension
We recommend the use of a belt
tensioner gauge in order to check the V-
belt tension. The tension check must be
carried out according to the
manufacturer’s manual.
Checking Tension Without Using a Belt
Tensioner Gauge
•
To check the tension, press the V-belt with
your thumb in the middle of the greatest free
length, and measure the sag.
•
Using medium thumb pressure of approx.
45 N, the V-belt sag (A) should equal approx.
10-15 mm.
Tensioning the V-belt
•
Slacken the fastening screws (47/1).
•
Swing the generator (47/2) until the tension is
correct.
•
Re-tighten the fastening screws.
•
Check the tension again.
7.9.7 Checking Valve Lash
The valve lash must be checked by your service
specialist.
Changing the V-belt
•
Slacken the fastening screws (47/1).
•
Swivel the generator against the direction of
tensioning.
•
Remove the used V-belt and fit new one.
•
Rotate the generator (47/2) in the direction of
the arrow until the V-belt tension is correct.
•
Re-tighten the fastening screws.
•
Check the tension again.
When new V-belts are mounted, their
tension has to be checked after the first
15 min. and adjusted if necessary.
