Installation：
——Clean cylinder head and valve cover
contacting surface.
——Push the wedge of valve cover seal gasket
into appropriate valve cover groove,
integrating valve cover with seal gasket.
——Install valve cover and seal gasket
assembly on cylinder head.
——Install 9 hexagon head bolts of long
column end with butterfly gasket，finger screw
them into cylinder head.
——Tighten bolts in two steps in order as
diagram showed.
Step 1：Tighten to 4.0—6.0Nm
Step 2：Tighten to 8.0—10.0Nm
【5】、Timing belt removal, installation and adjustment
Removal：
——Rotate crankshaft to no.1 cylinder compression TDC.
——Loosen 2 tension pulley mounting bolt (as arrow
indicated in diagram)，push tension pulley aside with a large
screwdriver.
——To release belt tension，tighten 2 tension pulley mounting
bolts with tension pulley in this position.
——To reuse belt，mark the direction of belt rotation and
make reference mark on crankshaft gear and camshaft gear
matching teeth，remove belt from camshaft gear, water pump
gear and crankshaft gear.

Note：With belt removed， don't turn gear excessively，or piston
head and valve may be damaged for contacting.
——If belt need to be reused ，check for improper
wear ,delaminate crack (particularly at the foot of teeth) or dirt. If
lightly suspected, replace it.
Installation and adjustment：
——Crankshaft should be positioned at no.1 cylinder TDC，if
necessary, crankshaft may only be turned slightly for adjustment
and blocked at flywheel ring gear.
——Engage timing belt tooth with crankshaft grooves，and pull
belt up straight to the right engaging belt with cam gear grooves.
During the installation of used belt, insure belt is in the right
direction and match belt with appropriate tooth.
With belt installed, 2 gears should not make any movement.
——Pull belt around tension pulley carefully，engage belt tooth
with gear teeth grooves.
Recheck both gears, there should be no movement.
——Loosen 2 tension pulley mounting bolts，push tension pulley
right to the extreme (viewed from the direction of pulley )，
tighten
2 tension pulley mounting bolts and loosen crankshaft locking
device.
——Rotate crankshaft clockwise (viewed from the pulley end) 2
turns until no.1 cylinder reaches its TDC of compression.
——Grab the midway of the right side belt between crankshaft
gear and camshaft gear with thumb and forefinger. If belt tension
is as specified, belt may be twisted 90°.
To adjust belt tension，loosen 2 tension pulley mounting bolts and
push tension pulley right side using screwdriver as push rod，then
tighten mounting bolts and rotate crankshaft. Recheck tension.
It may take 2- 3 times before tension is as specified. After
adjustment, tighten tension pulley mounting bolts to 16—20Nm.
——It is only a approximate method to adjust belt，and belt
tension should be checked as soon as possible by professionals
with special tools .
