05 COOLING SYSTEM<br />

SERVICE MANUAL MARINE ENGINES<br />

05.07.02 Adjust V-belts<br />

Measuring device No. VR00515/0 for timing- and V-belt<br />

For 6 cyl. engines only<br />

With engine stopped, belts should be stretched to<br />

such an extent that they yield for 10-13 mm when<br />

pressing your finger on marked spots (07.01 ill.4/ A +<br />

B). This corresponds to a belt tension of<br />

350 Nm +/- 50.<br />

If the belt is too loose, it may slip through which<br />

results in higher wear and bad efficiency of alternator<br />

or servo pump.<br />

Belt tension is to be checked after first 10 operating<br />

hours and than every 50 operating hours.<br />
