TIMING CHAIN

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 the figure
with the following procedure to install balancer unit.
CAUTION:
If mounting bolts are re-used, check their outer diameter
before installation. Refer to EM-57, "
Balancer Unit Mounting
Bolt Outer Diameter" .
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).
CAUTION:
Check tightening angle with angle wrench (SST) or a pro-
tractor. Do not make judgment by visual check alone.
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).

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 balancer unit timing chain by aligning mating marks on
each sprocket and balancer unit timing chain.
4. Install balancer unit timing chain tensioner.
NOTE:
Chain guide and tensioner move freely with 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-63, "
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.

d. Tighten mounting bolts in numerical order as shown in the fig-
ure.
e. Install intake valve timing control solenoid valves to intake valve timing control cover if removed.
f. Connect ground cables, and install harness clip.
10. Insert crankshaft pulley by aligning with crankshaft key.

When inserting crankshaft pulley with plastic hammer, tap on its center portion (not circumference).
CAUTION:
Install protecting front oil seal lip section from any damage.
11. Tighten crankshaft pulley bolt with the following procedure.

Secure crankshaft pulley with pulley holder [SST: KV10109300], and tighten crankshaft pulley bolt.
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.
d. Turn another 60 degrees clockwise (angle tightening).

Check the tightening angle with movement of one angle mark.
12. Install all removed parts in the reverse order of removal.
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.

INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter

Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.

If reduction of outer diameter appears in a position other than
“d2”, use it as “d2” point.
NOTE:
When replacing any cylinder head bolts, it is possible to use them
with mixing flange bolt and bolt with washer.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-102, "
CYLIN-
DER BLOCK DISTORTION" .
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.

If it exceeds the limit, replace cylinder head.Bolt with washer

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-14, "
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.

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. : 50.0 N·m (5.1 kg-m, 37 ft-lb)
