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.
