SECTION V MAINTENANCE
Adjusting belt tension
Check the belt exact tension by applying thumb pressure to the middle of
the longest part: the deflection should be approximately 10/12 mm
(0,39/0,47 in).
To adjust it, loosen the two fastening bolts and move the alternator.
Excessive tension may cause an accelerated wear and tear of the belt
between the fan and the alternator pulley. On the other hand, a belt that is
too loose or covered with grease may slip enough to cause engine
overheating and/or insufficient battery recharging.
N.B. - The belt should be replaced as soon as it shows any sign of fraying
or excessive wear of the sides.

CAUTION: IF THE BELT IS BROKEN DO NOT RUN THE ENGINE AS
THE COOLING FAN IS INOPERATIVE.
CAUTION: INSPECT THE DRIVE BELTS OVER THEIR ENTIRE
LENGTH. IF DAMAGED OR CRACKED, RENEW IMMEDIATELY.
