4. Adjust the gap between the belt and the clutch as
follows:
•
Move the engine away from the eccentric pulley to
reduce the gap between the belt and the sliding
cone (Figure 39).
•
Move the engine toward from the eccentric pulley
to increase the gap between the belt and the
sliding cone (Figure 39).
5. When the gap measurement is within the 0.76 to 1.27
mm (0.03 to 0.05 inch) range (Figure 38), tighten the
bolts and nuts that secure the engine to the engine deck
to 18 Nm (13 lb-ft).
