9. Belt Adjustment<br />

CAUTION:<br />

REMOVE THE IGNITION KEY BEFORE WORKING IN ENGINE COMPARTMENT.<br />

• Depress the longest run of the drive belt to be checked. If the travel exceeds 15 –20<br />

mm using hard finger pressure, the belt needs re-tensioning.<br />

• Loosen the upper adjuster bolts on the alternator, and the lower mounting pivot nut<br />

and bolt, either pull out using hand pressure or use the tensioning screw, depending<br />

on which alternator belt is to be tensioned.<br />

• Pull the alternator away from the engine to tighten the belt.<br />

• Hold the alternator in position and re-tighten all the bolts.<br />

• Note: if the belts are over tightened alternator bearing failure will occur.<br />

10. Belt Maintenance<br />

• Do not allow oil to contact the belt. Oil attacks the construction of the belt, reduces<br />

the drive efficiency, and will ultimately cause, it to fail prematurely.<br />

• Replace the belt, if it cracks; splits or as the adjustment nears the limit of its travel.<br />

• Note: Some boat builders may remove one or more alternators during installation, it is<br />

important that alternator alignment is perfect or premature belt failure will occur.<br />

11. Belt Replacement<br />

CAUTION:<br />

REMOVE THE IGNITION KEY BEFORE WORKING IN ENGINE COMPARTMENT.<br />

• Ensure that you have the correct new belts prior to starting this procedure. Some<br />

customers will order engines with non standard optional alternators that will have<br />

different belts to the standard ones listed; in this case make a note of the belt sizes<br />

when the engine is delivered<br />

• Loosen the top adjuster bolts, and the lower mounting pivot nut and bolt.<br />

• Push the alternator towards the engine to loosen the belt.<br />

• Remove the belt.<br />
