Check timing chain for cracks and any excessive wear at the roller
links of timing chain. Replace timing chain if necessary.
Balancer Unit Mounting Bolt Outer Diameter
Measure the outer diameters (“d1”, “d2”) at two positions as
shown in the figure.

INSTALLATION
NOTE:
The figure shows the relationship between the mating mark on each
timing chain and that on the corresponding sprocket, with the com-
ponents installed.
1. Make sure that crankshaft key points straight up.
2. Tighten mounting bolts in numerical order as shown in figure
with the following procedure, and install balancer unit.
CAUTION:
If mounting bolts are re-used, check their outer diameter
before installation. Refer to EM-50, "
INSPECTION AFTER
REMOVAL" .
a. Apply new engine oil to threads and seat surfaces of mounting
bolts.
b. Tighten all bolts.
c. Turn all bolts 90 degrees clockwise (angle tightening).
d. Completely loosen.
CAUTION:
In this step, loosen bolts in reverse order as shown in the
figure.
e. Tighten all bolts.
f. Turn them another 90 degrees clockwise (angle tightening).
CAUTION:
Check tightening angle with an angle wrench (special service tool) or a protractor. Do not make
judgment by visual check alone.

3. Install crankshaft sprocket and balancer unit timing chain.
Make sure that crankshaft sprocket is positioned with mating
marks on cylinder block and crankshaft sprocket meeting at
the top.
Install it by aligning mating marks on each sprocket and bal-
ancer unit timing chain.
4. Install balancer unit timing chain tensioner.
NOTE:
Chain guide and tensioner move freely with the staking pin as
the axle. Therefore, bolt hole position of the three points could
be changed during removal. If points change, temporarily fix the
two mounting bolts on chain guide, and move tensioner to mate
the bolt holes.
Be careful not to let mating marks of each sprocket and timing
chain slip.
After installation, make sure the mating marks have not
slipped, then remove stopper pin and release tensioner
sleeve.
5. Install timing chain and related parts.
Install by aligning mating marks on each sprocket and timing
chain.
Before and after installing chain tensioner, check again to
make sure that mating marks have not slipped.
After installing chain tensioner, remove stopper pin, and make
sure that tensioner moves freely.
CAUTION:
For the following note, after the mating marks are
aligned, keep them aligned by holding them with a
hand.
To avoid skipped teeth, do not rotate crankshaft and
camshaft until front cover is installed.
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.
6. Install front oil seal to front cover. Refer to EM-67, "
Removal and Installation of Front Oil Seal" .
7. Install front cover with the following procedure:
a. Install O-rings to cylinder head and cylinder block.

b. Apply a continuous bead of liquid gasket with a tube presser
(special service tool: WS39930000) to front cover as shown in
the figure.
Use Genuine Liquid Gasket or equivalent.
NOTE:
Application instruction differs depending on the position.
c. Make sure that mating marks of timing chain and each sprocket are still aligned. Then install front cover.
CAUTION:
Do not let A/C and power steering pipings interfere with upper part of front cover.
Be careful not to damage front oil seal by interference with front end of crankshaft.
d. Tighten mounting bolts in numerical order as shown in the fig-
ure.
e. After all bolts are tightened, retighten them to specified torque in
numerical order as shown in the figure.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking to
surface for fitting oil pan.
8. Install chain guide between camshaft sprockets.
9. Install intake valve timing control cover with the following procedure:
a. Install intake valve timing control solenoid valves to intake valve timing control cover if removed.
b. Install oil rings to the camshaft sprocket (INT) insertion points on backside of intake valve timing control
cover.
c. Install O-ring to front cover.Detail of A : Cross over the start of the applica-
tion and the end.
Detail of B : Apply liquid gasket outside of bolt
holes. (For all bolt holes other than
B, apply to the inside.)
Detail of C : Between here only, apply 4.5 - 5.5
mm (0.177 - 0.217 in) dia.

ure.
10. Insert crankshaft pulley by aligning with crankshaft key.
When inserting crankshaft pulley with a plastic hammer, tap on its center portion (not circumference).
CAUTION:

11. Tighten crankshaft pulley bolt.
Secure crankshaft pulley with a pulley holder (commercial service tool), and tighten crankshaft pulley
bolt.
Perform angle tightening with the following procedure:
a. Apply new engine oil to thread and seat surfaces of crankshaft pulley bolt.
b. Tighten crankshaft pulley bolt.
c. Put a paint mark on crankshaft pulley, mating with any one of six
easy to recognize angle marks on bolt flange.

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-17, "
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 the guide may
generate a pounding noise during and just after engine start. However, this is normal. 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.Item Before starting engine Engine running After engine stopped
