Section04ENGINE
Subsection 08 (CYLINDER HEAD AND VALVES)
Loosely install screws.
Install chain tensioner.
NOTE: There can be 2 different positions to install
the timing gear on the camshaft. Basically both
positions are working well, since the camshaft and
crankshaft are locked in their proper position. Due
to some tolerances, there could be one position
which fits better than the other one. To check this,
perform the following test.
Check if screws are still loose. If screws are
squeezed by the timing gear, remove the chain
tensioner again and rotate timing gear by one
tooth clockwise. Then install the chain tensioner
again.
Tighten screws and torque to 10 N•m(88lbf•in).
Remove locking tools.
CAUTION: Crankshaft and camshaft must be
locked on TDC position to place camshaft tim-
ing gear and timing chain in the proper posi-
tion. To double check, take a look at the timing
gear lines. They must be parallel to the cylin-
der head surface.
