MOVE GEAR BACK AND FORTH
1. Apply engine oil on the chain tensioner plunger
before installation.
2. Slightly turn the camshaft timing gear in order
to move the timing chain excess play to the ten-
sioner side.
3. Slightly screw in the plunger until the timing
chain does not allow back and forth movement
of the camshaft timing gear.
4. Screw the plunger in an additional 1/8 turn to
obtain the required specified torque.

(TIGHTENING TORQUE)
0.1 N•m (.9 lbf•in)
NOTICE
Improper adjustment of the timing
chain will lead to severe engine damage.
5. Insert the spring on one side into the slot of the
chain tensioner screw plug, and on the other
side, into the plunger.
NOTICE
Turn spring only clockwise in or-
der to fit the spring end into the notch of the
plunger to avoid loosening the plunger during
spring installation. Do not preload the spring.
NOTE: Do not forget to place the O-ring on chain
tensioner screw plug.
6. Then compress the spring and screw the plug
in.
NOTE: To avoid overstressing the timing chain,
the chain tensioner screw plug must engage in
the tensioner bore threads within the first full
turn.
7. Remove locking tool and install all other re-
moved parts.
