2. While holding the inlet camshaft hexagonal area 

with a wrench or a similar tool, slightly turn the 
exhaust camshaft clockwise to tighten the timing 
chain at the timing chain tensioner side and

chain tensioner.

CAUTION

Do not turn the crankshaft after removing the tim-
ing chain tensioner.
4. Loosen the timing chain tensioner mounting bolts,

5. Slightly raise the exhaust camshaft with the 

camshaft sprocket and timing chain assembly 
from the cylinder head, remove the camshaft 
sprocket mounting bolt, and disconnect the 
camshaft sprocket and timing chain assembly 
from the exhaust camshaft. 

6. In the same way as Step 5, disconnect the V.V.T. 

sprocket assembly and timing chain assembly 
from the inlet camshaft.

CAUTION

After disconnecting the camshaft sprocket and 
the V.V.T. sprocket assembly (with the timing 
chain for each) from the camshaft, do not dislo-
cate the camshaft sprocket, the V.V.T. sprocket 
assembly, and the timing chain.
7. After removal, place the camshaft sprocket and 

timing chain assembly, and the V.V.T. sprocket 
assembly and timing chain assembly on the 
timing chain case assembly

CAUTION

After removing the oil control valve and the oil 
control valve filter, be careful that no dust or 
other objects enter the oil passage in the cylinder 
head.
