１）

When there is no a flying wheel,

①

Use the gear belt of SST to wrap part of the

crankshaft pulley .

②

Lever of SST should be pulled to be immovable

(fixed),pay attention not to make the gear belt
moving,tighten the bolt according to the specified
torque of 98.0±10N.m{10±1kgm}

4）、When there is a flying wheel,

①

Use SST to prevent the toothed ring from turning

②

Then tighten bolt of torsional vibriation damper.

Attention· You must use SST to prevent the camshaft

from rotating.

3 Removal of camshaft cover cap and camshaft
bearing cover
(1) Align the marks on the camshaft gears as shown in
the right figure.

Set bolt

（

2）Use bolt to position the master and slave gears on

the air inlet camshaft, as shown in the right figure.

Attention In order to eliminte the radial force, keep the

camshaft in the leveled position before dismounting it
(to avoid possible damages caused by excessive radial
forces)

（

3）Remove the bolts in the sequence shown in the

right figure;

Remove the camshaft bearing cover

（

4）Remove the spark plug

（

5）Remove the camshaft slave gear. Use the special

tool as shown in the right figure.

Clip the camshaft tightly,use pin of SSTto insert the

two pin holes of the gear;turn the gear,to keep the bite
state of master and slave gear;remove the fixing bolts of
slave gear.
[Attention] Do not damage the surface of the camshaft.

2 Checks on camshaft axial clearance
（

1）、When the axial spacing is measured with a cliper

to be larger than the benchmark value, the camshaft is to
be replaced.
The air inlet camshat axial clearance is 0.1～0.170mm。
The air exhaust camshaft axial spacing is 0.1 ～
0.173mm。
Limits for operation：0.18mm

3-4 Cleaning
1、Clear off the spark plug carbon accumulation with a
metal brush.
