4. Install timing chains and related parts.
Align the mating mark on each sprocket and timing chain for installation.
NOTE:
Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for
that on each sprocket for alignment.
CAUTION:
For the above reason, after the mating marks are aligned, keep them aligned by holding them
with a hand.
Install slack guides and tension guides onto correct side by checking with identification mark on sur-
face.
Install chain tensioner with plunger fixed as described in its removal.
CAUTION:
Before and after the installation of chain tensioner, make sure that the mating mark on timing
chain is not out of alignment.
After installing chain tensioner, remove stopper pin to release tensioner. Make sure tensioner
is released.
To avoid chain-link skipping of timing chain, do not move crankshaft or camshafts until front
cover is installed.
5. Perform the same procedure as for right bank, install timing chain and related parts on left side.
6. Install oil pump. Refer to LU-30, "
OIL PUMP" .

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases 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 MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
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 timing chain tensioner drops after removal/installation, slack in guide may gen-
erate a pounding noise during and just after 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, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

3. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
CAUTION:
Do not loosen mounting bolts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike the piston head.
4. Remove intake and exhaust camshaft brackets.
Mark camshafts, camshaft brackets and bolts so placed in the same position and direction for installa-
tion.
Equally loosen camshaft brackets and bolts in several steps in
reverse order as shown in the figure.
Lightly tapping with plastic hammer, remove camshaft bracket
(No. 1) and camshaft bracket (No. 6).
NOTE:
The bottom surface of each bracket will be stuck to cylinder
head because of liquid gasket.
5. Remove camshaft.
6. Remove adjusting shim and valve lifter if necessary.
Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journal
of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the
camshaft runout on dial indicator (total indicator reading).
