TOP AND BOTTOM TIMING GEAR
COVER ASSEMBLY

Removal

Loosen and unscrew two bolts of the top timing
gear cover assembly.

Remove the top timing gear cover and

gasket

assembly.

Remove the gasket from the top timing gear
cover.

Remove the crank pulley.

Loosen and unscrew the two bolts on the timing
gear cover.

Remove the timing gear cover and gasket
assembly.

Remove the gasket from the bottom timing gear
cover.

Installation

Clean the bottom timing gear cover and fix the
new gasket on the bottom timing gear cover with
glue. Install the bottom timing gear cover and
gasket assembly on the crank shaft, screw in two
bolts by hands and tighten them for a moment of
9.0~11N.m.

Clean the top timing gear cover and fix the new
gasket on the top timing gear cover with glue. Fix
the top timing gear cover and gasket assembly on
the cylinder head with two bolts for a tightening
moment of 9~11N.m.

TIMING BELT REMOVAL

Rotate the crank shaft to the compression TDC
on the first cylinder. Loosen the two bolts on the
tension pulley (as indicated by the arrows in the
figure) and push the tension pulley towards one
side by a large-size screwdriver to release the
belt tension.

ENGINE TIMING

B-4

Note: After the belt is taken out, do not rotate

the gear to a large extent, otherwise the
piston head and the valve will be damaged
due to collision. To continue using the
removed belt, carefully check whether
there is abnormal abrasion, stratified
cracks (especially those around the root)
or fouling on the belt. Replace it
immediately even if the slightest suspicion
exists.

TIMING BELT INSTALLATION AND
ALIGNMENT

Check whether the crank shaft is in the TDC
position for the first cylinder. If necessary,
slightly rotate the crank shaft for alignment and
lock it around the flywheel ring gear. Make the
tooth of the timing belt and the gullet of the
flywheel in gear and drag the belt to the right in
an upward vertical direction to enable it to
engage with the cam gear and slot.

When installing the old belt, be sure to keep the
original direction of movement and engage it with
the original engaging teeth. After the belt is in
place, check it and be sure that the positions of
two gears haven’t been changed.

Carefully coil the belt around the tension pulley
to enable it to engage with water pump gear.
Check it again to ensure that the positions of the
two teeth haven’t been changed.

Loosen the two fixing bolts of the tension pulley
to try to push it to the right (seeing from the
direction of pulley) as possible, tighten its two
fixing bolts and loosen the locking device of the
crankshaft.

Rotate the crankshaft clockwise (seeing from the
direction of pulley) for two circles to the
compression TDC position on the first cylinder.

B-5

Hold the middle of the right belt that is away
from both the crankshaft gear and camshaft gear
with the thumb and the first finger. If the tension
of the belt is up to standard, the belt shall be
able to twist at 90°at this point.

To adjust the tension of the belt, loosen the two
fixing bolts of the tension pulley, push the
tension pulley to the right with a screwdriver as
a ram, then fasten the fixing bolts again, rotate
the crank shaft and check the tension again.
Right tension may be obtained after 2~3
adjustments. Fasten the tension pulley with
fixing bolts for a moment of 16-20N. after such
adjustments are completed.

DRIVER BELT, TENSION PULLEY AND
GENERATOR

Removal

Pull the abutment on the tension pulley by tools
to the direction of the generator (or align the
gauge holes on the front and rear part of the
tensioning device and drive a pin to fix the
tensioning device).

Remove the driver belt and the two fixing bolts
on the generator to take the generator out.

For installation, reverse the above removal
steps.

Tension pulley and Generator Bracket

Removal

Remove the three fixing bolts on the belt tension
pulley to take it out.

Loosen the connecting nuts on the cylinder head
and binding bolts on the cylinder block on the
generator bracket.

For installation, reverse the above removal
steps.

DETERMINATION OF ENGINE TIMING
（TDC FOR CYLINDER 1）

Unscrew 2 M6 bolts to remove upper timing gear
cover. Put one wrench on the bolts of crank
pulley, rotate the crank shaft clockwise (seeing
from the direction of pulley) until the top dead
center (TDC) gap indicator on the pulley lines up
with the TDC indicator (O) on the bottom timing
gear cover.

Note: The spark plug can be taken away

before rotating the crank for labor
saving.
