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.

3 Use SST to dismount the camshaft clockwise gear 

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.

(3) Use tensioning apparatus to remove the bearing use 
elastic snap ring,remove wave washer and teethed ring. 

 
 
 
 
 
 
 
 
 
 

3-3 Camshaft 
1 Use the caliper to measure the height of the camshaft. 
If it is below the specified limits, make proper 
replacement.

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
