12. Install crankshaft pulley as follows:
a.
Fix crankshaft using a suitable tool.
b.
Install crankshaft pulley, taking care not to damage front oil
seal.
I
When press-fitting crankshaft pulley with a plastic hammer, tap
on its center portion (not circumference).
c.
Tighten bolt to 39.2 to 49.0 N·m (4.0 to 5.0 kg-m, 29 to 36 ft-
lb).
SEM751G
d.
Put a paint mark on crankshaft pulley aligning with angle mark
on crankshaft pulley bolt. Then, further retighten bolt by 60 to
66 degrees [Target: 60 degrees (equivalent to one gradua-
tion)].
13. Rotate crankshaft pulley in normal direction (clockwise when
viewed from front) to confirm it turns smoothly.
14. For the following operations, perform steps in the reverse order
of removal.
I
If hydraulic pressure inside chain tensioner drops after
removal/installation, slack in the guide may generate a pound-
ing noise during and just after engine start. However, this does
not indicate an unusualness. Noise will stop after hydraulic
pressure rises.
