Changing the air cleaner cartridge

1. Working as illustrated, measure the tension of the belt using tool N° 1.824.018.000 (C.2.0131).

• Check that the tensions measured using the tool are within the specified limits.

The belt may be retensioned after a brief running-in period, proceeding as follows:

• bring the engine to the normal operating temperature
• turn the engine off and allow it to cool down
• retension the belt to the specified limit.

• If the tension found is incorrect, proceed as follows:

1. Slacken the two alternator fastening bolts.

• Move the alternator to one side and tighten the fastening bolt from the slotted side and check the belt tension.
• If the tension is correct also tighten the remaining fastening bolt.
• Suitably adapt the above procedure to change the alternator - water pump drive belt.

CHANGING THE AIR CLEANER CARTRIDGE

1. Slacken the four screws fastening the air cleaner cover.

1. Raise the air cleaner cover just enough to remove the filtering element.

Any filter cleaning operation might damage it, thereby jeopardising the correct operation of the engine supply system.

• Carefully clean the air cleaner cartridge container.
• Install a new air cleaner cartridge.
• Refit the cover and fasten with the corresponding screws.

NOTE: If the cleaner shows traces of oil, check for possible leaks in the entire air circuit.
