TIMING CHAIN
Revision: 2005 July 2005 FX
Install timing chain (primary) so the mating mark (punched) on
camshaft sprocket is aligned with the yellow link on timing
chain, while the mating mark (notched) on crankshaft
sprocket is aligned with the orange one on timing chain, as
shown in the figure.
When it is difficult to align mating marks of timing chain (pri-
mary) with each sprocket, gradually turn camshaft using
wrench on the hexagonal portion to align it with the mating
marks.
During alignment, be careful to prevent dislocation of mating
mark alignments of timing chains (secondary).
8. Install internal chain guide, slack guide and timing chain ten- sioner (primary).

CAUTION:
Do not overtighten slack guide mounting bolts. It is normal
for a gap to exist under the bolt seats when mounting bolts
are tightened to the specification.
When installing timing chain tensioner (primary), push in
plunger and keep it pressed in with a stopper pin.
Remove any dirt and foreign materials completely from the
back and the mounting surfaces of timing chain tensioner (pri-
mary).
After installation, pull out a stopper pin by pressing slack
guide.
9. Make sure again that the mating marks on sprockets and timing chain have not slipped out of alignment.
10. Install new O-rings on rear timing chain case.
11. Install new front oil seal on front timing chain case.
Apply new engine oil to both oil seal lip and dust seal lip.
Install it so that each seal lip is oriented as shown in the fig-
ure.

for locating bolts.
d. After all bolts are tightened, retighten them to the specified torque in numerical order shown in the figure.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking on surface mating with oil pan (upper).
e. After installing front timing chain case, check the surface height difference between the following parts on the oil pan (upper)
mounting surface.
If not within the standard, repeat the installation procedure.
14. Install right and left intake valve timing control covers as follows:
a. Install new seal rings in shaft grooves.
b. Apply a continuous bead of liquid gasket with the tube presser [SST: WS39930000 ( — )] to intake valve timing control cov-
ers as shown in the figure.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak.
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness.
Noise will stop after hydraulic pressure rises.
Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil
and engine coolant.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
