Fan and alternator drive belt
Check the belt tension every
10 h
or every day.
NOTICE:
Operating the engine with loosened belt may cause over heat of the engine or insufficient charging of the
battery due to slipping belt in its housing.
Inspection of tension
1. Apply finger pressure of about
10 kg
(
22.0 lb
) at the
midpoint of the belt, between the alternator pulley and
the crankshaft pulley, while the engine is shut down and
the starter key is removed.
2. Belt deflection should be about
7 – 9 mm
(
0.3 – 0.4 in
).
NOTE:
check any indication of damage on the pulley or belt
due to wear. Check thoroughly to make sure that the belt
is correctly engaged to groove of the pulley. The belt must
be replaced if it is elongated, it has cracks or it is worn out.
