The deflection should be approx. 17 to 19 mm (0.67 to 0.75 in)
when a point midway between the fan pulley and tension pulley is
pressed with the thumb with a force of 98 N (10 kg).
ADJUSTING
1. Loosen nut (1).
2. Use adjustment bolt (2) to move pulley (3) so that the deflection
is approx. 17 to 19 mm (0.67 to 0.75 in) when a point midway
between the fan pulley and tension pulley is pressed with the
thumb with a force of 98 N (10 kg).
When the belt is replaced with a new belt, the standard
deflection is 13 to 15 mm (0.51 to 0.59 in).
3. Check for damage to the pulleys, and wear of the groove and
belt. Be particularly careful to check that the belt is not in
contact with the bottom of the groove.
If the belt is stretched and there is no allowance for adjustment,
or it is cut or cracked, replace it with a new belt.
