How to check the drive belt of the
alternator
Note: The guard shown in (A) is for the four cylinder
engine.
Warning! All engines have a guard (A3) tted to give
protection from the alternator fan and the drive belt.
Ensure that this guard is tted before the engine is
started.
Renew the drive belt (A1) if it is worn or damaged.
To ensure maximum belt life, it is recommended that
a belt tensioner gauge, part number 21825686, is
used to check the belt tension. Fit the gauge (B) at
the centre of the longest free length and check the
tension. If a belt tensioner gauge is used, the correct
tension is 355 N (80 lbf) 36 kgf. If the tension is 220
N (50 lbf) 22 kgf or below, adjust the tension to 355
N (80 lbf) 36 kgf as indicated below.
If a gauge is not available, press down the belt
with the thumb at the centre of the longest free
length and check the deection. With moderate
thumb pressure - 45 N (10 lbf) 4,5 kgf - the correct
deection of the belt is 10 mm (3/8 in).
How to adjust the belt tension
1. Release the setscrews (A2) which secure
the guard for the drive belt to the engine and
carefully remove the guard.
2. Loosen the pivot fasteners (B1) of the alternator
and the adjustment link fasteners (B2).
3. Change the position of the alternator to give the
correct tension. Tighten the pivot fasteners of the
alternator and the adjustment link fasteners.
4. Check the belt tension again to ensure that it is
still correct
Note: If a new belt is tted, the belt tension must be
checked again after the rst 20 hours of operation.
5. Fit the guard for the drive belt to the engine and
fasten the two setscrews..
