Auxiliary unit belts

Fit support tool N° 1.820.260.000 on tool N° 1.824.016.000 (C.2.0129) and position the weight without the milled part, at a distance of 205 mm on the millimeter rule, and lock it in position.

1. Apply the tool assembled in this way, onto the belt tensioner as shown in the illustration and, acting on the articulation, move the rule until it is horizontal.
2. Settle the toothed belt by rotating the crankshaft twice in the normal direction of rotation.
3. Tighten the belt tensioner retaining nut to the correct torque.

CAUTION: During this operation the rule may move from its horizontal position. In this case it is necessary to act once again on the belt tensioner, return the rule to its original position and repeat the operation.

19.5 ÷ 24.2 Nm
2.0 ÷ 2.5 kgm

• Remove the belt tensioner tools.
• Tension the auxiliary unit drive belts (see specific paragraphs).

AUXILIARY UNIT BELTS

1. Alternator - water pump drive belt
2. Air conditioning compressor drive belt
3. Power steering pump drive belt
4. Power steering pump
5. Air conditioning compressor
6. Auxiliary unit control pulley
7. Alternator

NOTE: When checking the tension of the belt also check the belt for damage especially:

• - cuts
• - cracks
• - superficial wearing of material (shows up as smooth and shiny)
• - dry or hardened parts (loss of traction).

If one of the above is discovered, replace the belt.

CAUTION: If the belt comes into contact with oil or solvents its elasticity may be affected leading to a loss of traction
