3-5 Installation 
①

 Under the circumstance of using SST,use the special 

tools for fixing at the twoφ6 holes of the camshaft gear 
S/A. 
②

 Turn the slae gear to the right, match the mark hole 

on the slave gear with the mark on the master gear, or 
align the marks on the slave gear with the mark on the 
master gear; then fix the slave gear with bolt. (thread: 
M5; pitch: 0.8)

2、Installation of the camshaft 
[Attention] Size of the axial clearance of the camshaft 
(1)、Smear lubricating oil at the camshaft gear section 
and the cylinder cover axial diameter section. 
(2)、Fix the camshaft slave gear by roughly adjusting on 
the cyliner cover. 
(3)    It is necessary to measure the size of axial clearing 
of camshaft.

（

4）Install camshaft,the timing mark must be aligned 

shown as the    right figure. 

 

（

5）Smear lubricating oil on the camshaft assembly, the 

gears and the cyliner head axial diameter section. 
 

 

3 Tighten the camshaft bearing cap shown as right 
figure. 

 

 

4 Remove the bolt for fixing the slave gear of the 
camshaft assembly.

5 installation of camshaft head cap 
Smear the fluid sealant on the camshaft head cap section 
(with oil groove) shown as the right figure. 
 

 

 
Tighten the bolts according to the sequences shown as 
the right figure with the specified torques. 

 

6 After smearing oil in the plug cap hole and assembling 
surface of the plug,use SSTto press the plug lid 

Attention· Install the plug lid shown as the right 

illustration. 
Keep unbiased with cylinder head end surface after 
pressing.

7 Smear engine oil on the oil seal installation port of 
cylinder head,camshaft oil seal edge of blade and outside 
ring,use M10 bolt (length 50-60 mm) and SST press the 
cylinder,lower 1mm thatn the end surface of the 
cylinder4 head. 

Attention ·Under the condition of use the oil seal 

repeatedly,press here with engine oil adhesive agent 
- The oil seal should not be pressed inclining to one side.

8 Installation of the timing gear of camshaft 
After smearing the fluid sealant,use SST to prevent 
rotating,tighten the timing gear bolt of camshaft 
according to regulated torque of 100±5N.m. 

 
 
 
 
 
 
 
 

9 Installation of valve chamber cover cap 

The used base facing the cylinder cover of the timing 

⑴
belt cover must be cleaned thoroughly. 

Install the new base correctly into the groove of the 

⑵
valve cage cover cap 

Install valve cage cover cap to cylinder head 

⑶

from two 

sides to the centre symmetrically according to the 
regulated torque of 6±1N.m 

 

1 Use feeler gauge to check the throttle clearance. 

Attention·Make sure to measure the clearance between 

basic circle of cam and valve adjusting gasket. 

Standard of valve clearance : 

IN

0.18±0.05 

valve 

spacing 

EX

0.25±0.05 

1 When it is beyond the benchmark value, the 
adjustment washer has to be replaced and the clearance 
should be adjusted. 
[Attention] The valve number that goes beyond the 
benchmark value has to be recorded, and the result of 
measurements should be recorded as welll 

 

  (1) Use a caliper to measure and adjust the thickness of 
the separation cushion.

(2)Select proper separation cushion on the basis of the 
throttle thrusting rod benchmark values. 

 

①

 IN 

Selected cushion thickness = removed cushion 
thickness + (measured throttle spacing – 0.18mm) 

 EX

②

 

Selected cushion thickness = removed cushion 
thickness + (measured throttle spacing – 
0.25mm） 

[Reference] there are 32 kinds of shim is thickness , 
shown as the illustration

2.32 2.54 2.76 
2.38 2.6     

 

(7) Use the selected adjusting gasket to adjust the 
throttle clearance. 
[Attention] Install the the feeler with the identification 
mark facing downwards. 
 

 

Forword 
lower 

 

(1) Turn the camshaft,make the cam lobe upwards to 
make things convenient for replacing the gasket,make 
the valve thrusting rod gap towards the inside. 
 

 

  (2) Turn the crankshaft and the bulging top of the cam 
presses down the valve thrusting rod.
