CRANK PULLEY WRENCH

(1) Clean the crankshaft thread using com-
pressed air.
(2) Apply engine oil to the crank pulley bolt seat
and thread.
(3) Tighten the bolts temporarily with tightening
torque of 44 N·m (4.5 kgf-m, 32.5 ft-lb).
(4) Tighten the crank pulley bolts.

Tightening torque:

130 N·m (13.3 kgf-m, 95.9 ft-lb)

3) Check that the tightening angle of the crank pul-
ley bolt is 45° or more. Perform the following proce-
dure when less than 45°.

CAUTION:
If the tightening angle of crank pulley bolt is
less than 45°, the bolt is damaged. In this case,
the bolt must be replaced.

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