22.6 N·m (2.3 kgf-m, 16.6 ft-lb)

C: INSPECTION

1) Replace the belts, if cracks, fraying or wear is
found.
2) Check the drive belt tension and adjust it if nec-
essary by changing the generator installing position
and/or idler pulley installing position.

CRANKSHAFT PULLEY 
WRENCH

(1) Clean the crankshaft pulley thread using an
air gun.
(2) Apply engine oil to the crankshaft pulley bolt
seat and thread.
(3) Tighten the bolts temporarily with tightening
torque of 44 N·m (4.5 kgf-m, 33 ft-lb).
(4) Tighten the crankshaft pulley bolts.

Tightening torque:

127 N·m (13.0 kgf-m, 94.0 ft-lb)

3) Confirm that the tightening angle of crankshaft
pulley bolt is 45 degrees or more. If the tightening
angle of crankshaft pulley bolt is less than 45 de-
grees, conduct the following procedures.

(1) Replace the crankshaft pulley bolts and
clean them.

Crankshaft pulley bolt:

(2) Clean the crankshaft thread using an air
gun.
(3) Apply engine oil to the crankshaft pulley bolt
seal and thread.
(4) Tighten the bolts temporarily with tightening
torque of 44 N·m (4.5 kgf-m, 33 ft-lb).
(5) Tighten the crankshaft pulley bolts keeping
them in an angle between 45 degrees and 60
degrees.

NOTE:
Conduct the tightening procedures by confirming
the turning angle of crankshaft pulley bolt referring
to the gauge indicated on belt cover.
4) Install the A/C belt tensioner.

5) Install the A/C belt.
