Water Pump / Generator Drive Belt Tension Inspection and Adjustment

Precautions: Precautions for Handling Battery · Precautions for Replacing Battery · General safety (00)

1)Check water pump / generator drive belt for crack, cuts, deformation, wear and cleanliness. If it is necessary to replace water pump / generator drive belt, refer to Water Pump / Generator Drive Belt Removal and Installation:K14C.

2)Check water pump / generator drive belt for tension. Water pump / generator drive belt is in proper tension when it deflects as follows under thumb pressure (about 100 N (10.2 kgf, 22.5 lbf).).
If belt tension is not as specified, go to next steps.

Water pump / generator drive belt tension “a”

Existing belt: 4.9 – 5.6 mm (0.19 – 0.22 in.) as deflection / 100 N (10.2 kgf, 22.5 lbf)

New belt: 3.7 – 4.7 mm (0.15 – 0.19 in.) as deflection / 100 N (10.2 kgf, 22.5 lbf)

3)Loosen generator bolt (1), pivot bolt (2) and then adjust belt tension to specification described at Step 2) by loosening / tightening generator adjusting bolt (3).

4)Tighten generator bolt and pivot bolt to specified torque.

Tightening torque

Generator bolt (a): 25 N·m (2.5 kgf-m, 18.5 lbf-ft)
Generator pivot bolt (b): 48 N·m (4.9 kgf-m, 35.5 lbf-ft)

5)Check belt tension for specification after turning crankshaft two revolutions clockwise.
