11. Belt Maintenance
WARNING:
SEVERE HAZARD!
KEEP HANDS AND OTHER BODY PARTS AWAY FROM
MOVING/ROTATING PARTS. WEAR TIGHT FITTING CLOTHING AND KEEP YOUR
HAIR SHORT OR TIE BACK. REMOVE ALL JEWELLERY BEFORE COMMENCING
WORK. CHECK BEFORE STARTING THE ENGINE THAT ANY TOOLS OR RAGS
USED DURING MAINTENANCE HAVE BEEN REMOVED FROM THE AREA.
Ensure the ignition key is removed before carrying out any maintenance.
Turn the battery master switch to the off position before carrying out any maintenance.
Do not allow oil to contact the belt. Oil attacks the construction of the belt. This reduces
the drive efficiency and ultimately cause it to fail prematurely.
Replace the belt if it cracks or splits and as the adjustment nears the limit of travel.
Some boat builders may remove one or more of the alternators during the
installation of the engine. It is essential that when the alternators are refitted that the
alignment is perfect or premature belt wear will occur.
