05 COOLING SYSTEM
05.07.02 Adjust V-belts
Measuring device No. VR00515/0 for timing- and V-belt
For 6 cyl. engines only
With engine stopped, belts should be stretched to
such an extent that they yield for 10-13 mm when
pressing your finger on marked spots (07.01 ill.4/ A +
B). This corresponds to a belt tension of
350 Nm +/- 50.
If the belt is too loose, it may slip through which
results in higher wear and bad efficiency of alternator
or servo pump.
Belt tension is to be checked after first 10 operating
hours and than every 50 operating hours.
