CHECK AND RESTORE ALTERNATOR BELT
(see also Engine Manual)
Only open the hood with the engine shut off
To optimize engine performance, check that belts are not worn or cracked.
Replace worn or damaged belts. For applications that require multiple
transmission belts, replace the entire assembly. The replacement of one single
belt of a group will make the new belt bear most of the load, due to the older one
is loose. This additional load on the new belt will break it.
If belts are too loose, the vibrations resulting cause unnecessary wear of the
belts and pulleys. A slack belt may slip enough to cause overheating.
To control the belt tension properly, use an appropriate indicator.
As an alternative, check that the belt between the alternator and the drive pulley
has an approximately tension of:
50+60 N (5+6 kg) pre-installed
70+80 N (7+8 kg) new
By using the informal method to check the tension (see figure on the right), the
belt shoudl not give more than 10 mm when pressed.
To adjust tension see
Engine Manual.
