Fig. 4-1-45 Installing the timing belt
shaped plug is installed on the cylinder head, and then
use a hexagon socket head spanner to turn the
pinhole-mounting position clockwise until it is slightly over
30°past the vertical direction and the tension pulley arm
indicator is 1°~2°past the lower verge of the installation
arm notch, and tighten the fastening bolts. After taking off
the hexagon socket head spanner, camshaft pulley dowel
pin and crankshaft locking tooling, turn the crankshaft 2
circles clockwise with the spanner to make sure the
damping pulley, camshaft timing pulley and fuel pump
pulley align with the timing mark and the belt fits properly.
If there is any pulley that is not aligned properly, loosen
the fasting bolt of timing pulley and install them again to
align the pulley properly. So that one cylinder is just at the
top dead center of the compression stroke, and the valve
timing is accurate. See Fig. 4-1-46.

Attention:
If any pulley mark is not aligned and it is
required to turn the vehicle to align or inspect it, never
turn the vehicle anticlockwise. See Fig. 4-1-46.

(7) Install the timing hood and timing hood component I.
Screw down 10 hexagon flange bolts (M6×16, M10×35
and M10×50) to the front end of cylinder head and
cylinder body by using the specified torque. See Fig.
4-1-47.

Reinstalling the engine accessories
①
(1) Reinstall the wedge idle wheel to the front end of the
cylinder body and tighten it to the required torque.
Visually checked, the pulleys should be on the same
plane.
