Servicing The Air Cleaner - Toro 30581 Groundsmaster 580-D Operator's Manual

4. Every 100 hours operation, inspect fan belt for
condition and proper tension. Replace belt if condition
warrants. Check and adjust tension as follows:
A. Unlatch and raise hood and prop it open. Unlatch
and remove right side panel.
B. Proper tension will allow 1/2 in. (13 mm) deflection
when a force of 10 lb. is applied on the belt midway
between the pulleys. If deflection is incorrect,
proceed to step C; if deflection is correct, install
panel and close hood.
C. Loosen the 3 bolts securing alternator to plate and
mounting bracket (Fig. 43). Rotate alternator away
from engine to increase tension and tighten bolts.
Check belt tension after adjustment and re-adjust, if
necessary.
