Chery A15. Manual - part 12

 

Pries the rear oil seal out of the rear oil seal 
support with a chisel or a screwdriver. Note: do 
not damage the rear oil seal support. 

 

 

 

 

 

 

Installation 

Put the support on the vice clamp whose jaw 
has a piece of wood.   

Make the side with the part numbers of the rear 
oil seal outward and align the rear oil seal with 
the rear oil seal support bore. Press the rear oil 
seal into its support with a vice clamp, with the 
clearance between the rear oil seal and oil seal 
support bore to be 0.26—0.50mm. 

 

 

 

 

Install the new rear oil seal support gasket. 

Install the rear oil seal assembly. Before 
assembling, wrap a piece of plastic plate on the 
crank shaft to avoid colliding the oil seal. And 
apply some motor oil on the oil seal edge and 
oil seal journal.   

Measure the out-of-flat of the bottom plane of 
the rear oil seal bracket and the sump flange 
surface of the cylinder block, which shall be 
within the range of  ±0.26mm. 

 

 

 

Tighten the 4 M6 bolts to a moment of 
8.0-11.0Nm. 

Take away the plastic tape.

CAMSHAFT 

CAMSHAFT GEAR 

Removal 

Rotate the crankshaft to the compression TDC 
position of the first cylinder. 

Remove the belt. 

Put one pole into one hole of the cam shaft gear to 
lock it. Loosen the gear bolts and remove them and 
the gasket.   

Note:  

New bolts shall be used for reinstallation. The 
camshafts of different engines are not 
interchangeable. In case the cam shaft shall be 
replaced, replace it with a new one according to 
the indicators on the original gear. 

 

Installation 

Check whether there are abrasion, pit corrosion or 
scrapes on the gear.   

Install the whitney key of the cam shaft, with a 
protrusion height of 1.64-2.11mm. 

Install the camshaft gear onto the camshaft and put 
new bolts into the gasket. The new bolts that 
haven’t been applied with a coat of glue in 
advance shall be applied with a coat of glue first 
and be tightened for a moment of 52-60N.m. 

Check whether the crank shaft is in the 
compression TDC position. 

 

CAMSHAFT AND CAMSHAFT THRUST 
SPACER 

 

Removal 

Measure the axial clearance of the cam shaft, 
which shall be between 0.049~0.129mm. 

Loosen the bolts of the thrust spacer to take them 
out.  

Take the thrust spacer out (as illustrated in the 
figure). 

 

 

 

   

 

 

B-25

Draw the cam shaft assembly out from the rear end
of the cylinder head and be careful not to damage
the cam shaft hole of the cylinder head during this
process. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Inspection 

Check whether there is any abrasion on the cam 
and the journal of the cam shaft. Change the one 
with serious abrasion.   

Change the thrust space if the axial clearance of 
the cam shaft is above the specification.   

Measure the bore diameter of the cam shaft of the
cylinder head or check the relative displacement of
the journal and bore with the cam shaft. Change the
cam shaft if the bore is excessively wore.

SIZE OF CAMSHAFT JOURNAL AND 
HOLE OF THE CYLINDER HEAD 

Installation 

To replace the cam shaft, observe the shape of the 
rear end of the cam shaft for right selection. 

Before installation, apply the cam of the cam shaft 
with hyperbolic gear oil or motor oil. The cam 
shaft shall be assembled from the cylinder head in 
a back-to-front order. 

Apply some motor oil to the thrust spacer of the 
cam shaft and put the thrust spacer into the groove 
of the cylinder head. 

Screw two bolts into the threaded holes of the 
thrust spacer and tighten them for a moment of 
9—13Nm. 

Check the axial clearance of the cam shaft, which 
shall be within the specified range. 

If adopting oversized hydraulic tappet (0.25), a 
carefully selected cam shaft shall be used, 
otherwise it will block the hydraulic tappet.
