EM-197, "FRONT OIL SEAL : Removal and Installation"
7.
Install front cover with the following procedure:
CAUTION:
Do not reuse O-rings.
a.
Install O-rings to cylinder head and cylinder block.
b.
Apply a continuous bead of liquid gasket with the tube presser
(commercial service tool) to front cover as shown in the figure.
Use Genuine Liquid Gasket or equivalent.
NOTE:
Application instruction differs depending on the position.
c.
Check that mating marks of timing chain and each sprocket are still aligned. Then install front cover.
CAUTION:
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.

TIMING CHAIN
a.
Install valve timing control solenoid valves to valve timing control cover if removed.
b.
Install new oil rings to the camshaft sprocket (INT) insertion points on backside of valve timing control
cover.
c.
Install new O-ring to front cover.
d.
Apply a continuous bead of liquid gasket
with a tube presser
(commercial service tool) to valve timing control cover as shown
in the figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
• Attaching should be done within 5 minutes after liquid
gasket application.
• Do not reuse O-ring.
e.
Tighten mounting bolts in numerical order as shown in the fig-
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:
Install protecting front oil seal lip section from any damage.
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.
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.

INSPECTION AFTER REMOVAL
Timing Chain
• 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.
• If reduction appears in “A” range, regard it as “d2 ”.
• If it exceeds the limit (large difference in dimensions), replace it
with a new one.
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
MA-23, "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 leak-
age 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 check 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.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
