MAINTENANCE
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 tensionner 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.
FUSES
The engine electrical system is protected from electrical
overloads by fuses. On N4 engines, fuses and relays are
located in the electrical loom.
If the engine does not start or if the instruments panel
does not operate, a fault might be somewhere in the
electrical system and a fuse may have blown up.
Investigate the cause before replacing the faulty fuse
straight away. Keep an assortment of spare fuses on
hand. Replace a fuse with one of the same rating.
