General
Check belt tension and condition regularly. If the belt
is too taut it can damage bearings and if it is too loose
it may slip. Check and adjust after operation when the
belt is warm.
IMPORTANT! Always change a belt that ap-
pears worn or is cracked (belts working in pairs
must be replaced together).
Poly-V belt
The alternator and circulation pump are driven by a
Poly-V belt for best function and service life.
A torque wrench must be used for adjustment.
1. Undo screws (A) before you tension the belt.
2. Change the belt as necessary.
3. Put the torque wrench stub into the square hole in
the jockey wheel bracket. Tension the belt with 60
±3 Nm (6 ±0.3 kpm /44 ± 2 lbf.ft).
4. Tighten screws (A).
Other belts
Also check the belts for the bilge and flushing pump,
extra alternator etc. These are usually driven by con-
ventional V- belts.
Adjust and change as necessary. It can generally be
said that these belts are correctly tensioned if they
can be pressed down 10 mm (3/8") by thumb pres-
sure.
Clean the belt grooves before fitting a new belt.
