1 Even if the damages on the outer appearance can not be confirmed, the belt should be replaced 
under any of the following circumstances: 
（１）

、

If the water in the water pump is leaked, which makes it necessary to refill the water 

continuously; 
（２）

、

There are much oil stains on the belt, the belt should be replaced for the rubber will be 

damaged when it is expanded;

Installation 
1 Installation of crankshaft timing gear 
 

 

2 Installation of timing belt 
(1)On the upper thrust point of the first cylinder 
compression 
① 

Place the camshaft timing gear around the front 

end of the air exhaust camshaft so as to make the 
positioning groove on the gear be aligned with the 
positioning pin on the end surface of the camshaft. 
Then use screws to fix the clockwise gear, with the 
torque of 100 ± 5N.m. 
 

 

 (2) Make sure that the punched mark on the 
crankshaft clockwise pulley is aligned with the mark 
of the oil pump. 
 

 

 
（

3）Install timing pulley accordingly.

3 Install the tensioner 
（１）

Adjust the tension of the timing belt 

As shown in the figure, make the space between the 

①
edge of the stretching wheel and the water pump case 
arc to be about 8mm;   

Tig

②

hten the bolt of the stretching wheel with a 

torque of 25 ± 3N.m. Use a screwdriver to swing the 
stretcher toward the right.. 
 

 

 

③

 Turn the crankshaft for two circles towards the 

engine rotating  direction, so that the camshaft pulley 
and the crankshaft pulley matches the clockwise marks 
respectively. 

 

④

 Use hands to press down for about 5mm. The force 

for pressing the clockwise belt is about: ［Referrence］
20～30  N 
Notice: When the deflection of the timing belt fails to 
meet the specifications, the key is to adjust the 
above-mentioned stretcher fastening bolt by widening 
the spacing. 
Tighten the S/A fixing bolt of the stretcher with the 
specified torque of 25 ± 3N.m 
 

 

 
4 Install the baffle of the crankshafte timing pulley 
[Attention] Install the baffle towars the direction 
shown in the right figure.
