CAMSHAFTS
Make sure each camshaft cap is installed in its
original place. Refer to the identification marks
as follows:
“IN”: Intake
“EX”: Exhaust
3. Install:
• Camshaft cap bolts
ECA13730
The camshaft cap bolts must be tightened
evenly or damage to the cylinder head, cam-
shaft caps, and camshafts will result.
• Lubricate the camshaft cap bolt seats with the
engine oil.
• When tightening the camshaft cap, tighten the
four bolts on the both ends of the cap tempo-
rarily to lower the entire cap, while paying at-
tention not to twist the dowel pins and camshaft
journal. After the camshaft cap touches the cyl-
inder head, tighten the two bolts in the middle
to the specified torque and then the remaining
four bolts to the specified torque.
• To prevent the camshaft cap from cracking,
tighten the camshaft cap carefully by tapping
the camshaft using a soft-face hammer (both
for temporary and final tightening).
4. Install:
• Timing chain tensioner gasket
• Timing chain tensioner
a. Using the valve spring compressor “1”,
push and insert timing chain tensioner rod
“2” into the timing chain tensioner housing.
Push the timing chain tensioner rod in direction
“a”, and turn the timing chain tensioner body “3”
in direction “b” until the circlip fits into the groove.
b. Lock the timing chain tensioner rod by set-
ting the circlip “4” into groove “5” while
pushing the timing chain tensioner rod.
c. Install the timing chain tensioner to the cyl-
inder block.
Always use a new gasket.
d. Turn the crankshaft counterclockwise sev-
eral times to release the timing chain ten-
sioner rod.
