10.6.2. Poly-V-belt of the alternator
The alternator and the air condition pump are driven by the poly-V-belt of the alternator.
Replacing the poly-V-belt of the alternator
1. Remove the poly-V-belt (see § 10.6.1. Poly-V-belt );
2. Loosen the automatic belt tensioner:
- It is possible to block the belt tensioner temporarily with a 4 - 5 mm pin or drill
( Picture 10-28 , B );
3. Relax the poly-V-belt of the alternator, so it can be removed from the pulleys;
4. If the tensioner is not temporarily blocked, then let the automatic belt tensioner slowly cushion
to the stop;
5. Remove the poly-V-belt of the alternator;
6. Check the pulleys for damages, rust and grease deposits;
7. Put the poly-V-belt of the alternator over as much pulleys as possible;
8. Tension the automatic belt tensioner (if not temporarily blocked) and put the poly-V-belt of the
alternator over the last pulleys;
9. Let the automatic belt tensioner slowly cushion to the new poly-V-belt of the alternator;
10. Remove the blocking pin, if applicable:
- By moving the tensioner against the spring force, the blocking pin can be removed;
11. Check if the poly-V-belt of the alternator is placed in all grooves of all pulleys;
12. Mount the fan with visco-coupling and tighten it firmly:
- Use a thread sealing or thread locking (Loctite).
CONDITIONS
The main switch of the truck must be turned off.
CAUTION!
Always mount a new poly-V-belt of the same type
(see § 14.1. Maintenance
specifications).
