ALTERNATOR BELT
The engine alternator is driven by a belt through pulleys.
These components must be in good order at all times in
view for the alternator to provide electricity, among others,
to the engine, to the battery, to the engine control panel.
DANGER !
Stop the engine and remove the key before checking or
servicing the alternator belt.
NOTE !
Always keep a spare replacement belt on-board.
IMPORTANT !
A loosen or damaged belt can result in overheats or lack
of alternator charge. A too tighten belt can damage the
bearings of the water pump and of the alternator.
Visual check of the belt:
If belt internal wires become visible and frayed, replace
the belt. Check that belt fits properly in the pulley. Belt is
constantly tensioned by an automatic belt tensioner.
Check the belt tension:
Depress the belt at point (A)
and check for a deflection
between 7 and 9 mm.
If not within specification, loosen the alternator (in grey on
picture) and relocate it properly to adjust.
To replace the belt:
1. Stop the engine and remove the key from the panel.
2. Move the tensioner mechanism using a wrench and
slip out the belt from the alternator pulley. Remove it
completely.
3. Install the new belt. Check that the belt seats nicely
between the flanges of all the pulleys.
4. Check the tension after few hours of operation.
