Cylinder Head Bolts; Engine Valve Clearance; Adjusting Accelerator Pedal; Changing Transaxle / Hydraulic Fluid - Toro 07213 Operator's Manual

Using a bar, rotate alternator until proper belt tension is
attained, then tighten mounting bolts.
Fan belt
1. Check tension by depressing belt at mid span of fan and
drive shaft pulleys with 22 lbs. of force. A new belt
should deflect .48–.58 in. A used belt should deflect
.55–.65 in. If deflection is incorrect, proceed to next
step. If correct, continue operation.
2. To adjust belt tension:
Loosen idler pulley mounting nut, move pulley to
increase tension and tighten nut.
