Fan Belt - Branson 6640C Operator's Manual

10. FAN BELT

Carry out inspection or maintenance after
the engine if fully cooled down.
WARNING
[Otherwise]
There is a risk of getting burnt.
After removing right side of dashboard, loosen fixing nut
and adjust stopper bolt so that the gap between stopper
bolt head and brake pedal arm is 0 ~ 0.02in [0~0.5mm]
and tighten the fixing nut again.
Open the engine hood and press the middle of fan belt
with finger to see if the belt sags about 0.4 ~ 0.6in [10
~15mm]or if there is any damage to the belt. If the sag-
ging is not correct, loosen the alternator bolt and move
the alternator to adjust the tension of the fan belt. If the
fan belt still slips after the alternator is moved to the max-
imum, replace the belt with a new one. New belts must
be inspected after 50 hours of use.
