Checking the drive belt
Before starting, make a note of how the drive belt
is fitted. Refit the drive belt with the same direc-
tion of rotation as it had before removal.
1. Check the drive belt thoroughly, particularly
at the idler rollers.
2. Check the drive belt for cracks. Renew the
drive belt if deep cracks have formed.
Small and shallow cracks are normal and form
after only a few hours of operation. They do not
mean that the drive belt needs to be renewed. If
there are many deep cracks, or if parts of the
drive belt have started to come off, the drive belt
must then be renewed.
Example of a minor crack in the drive belt. The drive
belt can be refitted.
The drive belt has deep cracks and must be renewed.
Example of a drive belt:
1. Crankshaft
2. Idler roller
3. Alternator
4. Belt tensioner
5. Coolant pump
