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

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

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.

IN

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

EX

(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.
