Chery A15. Manual - part 232

 
 
1. M10 bolts of the cylinder cover 
2. Cylinder gasket 
3. Cylinder cover 
4. M8 bolts of the cylinder cover 
 
 
 
 
 
 
 
 
 
 
2. Cleaning 
The sealing surface must be clean to 
ensure the sealing of the cylinder, which 
is especially important in the case of 
aluminum gasket when all foreign 
matters on the cylinder cover shall be 
removed and all engine oil paths shall be 
cleaned.  
3. Checking 
(1) The required evenness is 0.1mm 
(0.004in.) (Figure 33). 
 
1. Clearance gauge 
2. Ruler 
 
 
 
(2) Check if the camshaft bearing bush is 
free of scratches.  
(3) Clean the oil on the valve conduit.  
(4) Measure the valve conduit with a dial 
indicator (Figure 34) (see Engine – 
Troubleshooting Procedure).

4. Fix the cylinder cover 
Note: Check the cylinder cover bolts 
before fixing the cylinder cover. Replace 
if any trouble is discovered (Figure 35).  
1-Bolt is not elongated 
2-Screw thread is uneven..  
3-Screw thread is curved..  
4-Bolt is elongated 
 
 
(1) Clean the cylinder cover surface and 
cylinder sealing surface.  
(2) Place new gasket onto the 
positioning lock.  
(3) Place the cylinder cover onto the 
cylinder body and make sure that the 
cylinder cover is fully set into the 
positioning lock.  
(4) Apply engine oil onto the cylinder 
cover bolts before screwing them on.  
(5) Screw on the cylinder cover bolts in 
sequence (Figure 36) and the screwing 
torque is as follows:  
 
 
Step One 
Screw on the 10 pieces of M10 bolts 
with a torque of 20N.m (15ft.lbs.) 
Screw on the 2 pieces of M8 bolts with a 
torque of 15N.m (11ft.lbs.) 
Step Two 
Screw on the 10 pieces of M10 bolts 
with a torque of 41N.m (30ft.lbs.) 
Step Three 
Screw on the 10 pieces of M10 bolts 
again with a torque of 41N.m (30ft.lbs.) 
Step Four 
Turn the 10 pieces of M10 bolts by 90 
degrees (do not use torque spanners).  
Screw on the 2 pieces of M8 bolts with a 
torque of 30N.m (22ft.lbs.).

(6) Fix the timing chain guide board 
with a torque of 28N.m (250in.lbs) 
(Figure 31).  
(7) Resume the timing chain’s mark on 
the crank shaft.  
(8) Align the camshaft sprocket wheel 
with the triangle timing mark.  
Note: do not use pneumatic tools to 
screw fast the camshaft sprocket 
wheel.  
(9) Fix the camshaft sprocket wheel with 
special tools and screw on the camshaft 
sprocket wheel bolts with a torque of 
15N.m (85ft.lbs) (Figure 15).  
(10) Readjust the timing chain tensioner 
as follows:  

 

(A) Unfix the timing chain tensioner’s 
engine oil chamber (Figure 37).  
 
 
1-Check valve 
2-Plug with seal 
3-Engine oil chamber 
4-Timing chain tensioner 
 
 
 
 
(B) Place the timing chain onto a clean 
surface.  
(C) Press open the tensioner check valve 
and keep pressing down manually until it 
lowers to the bottom (Figure 38).  
(D) Fix the engine oil chamber into the 
timing chain tensioner.  
(11) Fix the timing chain tensioner onto 
the cylinder body.  
(12) Fix the timing chain tensioner with 
a torque of 62N.m (46ft.lbs). 
(13) Pry in the right timing chain guide 
board with a long screw driver until the 
tensioner is set into the sprocket wheel 
position (Figure 39).
