Camshaft T
iming Gear Inspection
Check camshaft timing gear for wear or deteriora-
tion.
If gear is worn or damaged, replace it as a set
(camshaft timing gear and timing chain).
For cranks
haft timing gear, refer to
CYLINDER
BLOCK
sub
section.
Camshaft Timing Gear Installation
For insta
llation, reverse the removal procedure.
Pay atten
tion to the following details.
NOTICE
Improper camshaft timing will dam-
age engine components. Make sure camshaft
and crankshaft are still locked. If not, lock them
before beginning this procedure.
Install the camshaft timing gear with the writing
visible, i.e. to be able to see the position lines
when looking from outside of engine.

Install timing chain. Refer to
CYLINDER BLOCK
subsection.
Ensure chain guides are in place.
Loosely install timing chain 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 po-
sition which fits better than the other one. To
check this, perform the following test.
Check if timing chain 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.
One at a time, remove timing chain screws and
apply
LOCTITE 243 (BLUE) (P/N 293 800 060) on
threads.
Tighten timing chain screws to 9 N•m (80 lbf•in).
NOTICE
Crankshaft and camshaft must be
locked on TDC position to place camshaft
timing gear and timing chain in the proper
position. To double check, take a look at the
timing gear lines. They must be parallel to the
cylinder head surface.
