GENERAL TORQUE
This chart specifies tightening torques for stan-
dard fasteners with a standard ISO thread
pitch. Tightening torque specifications for spe-
cial components or assemblies are provided in
applicable sections of this manual. To avoid
warpage, tighten multi-fastener assemblies in
a crisscross fashion and progressive stages
until the specified tightening torque is reached.
Unless otherwise specified, tightening torque
specifications require clean, dry threads.
Components should be at room temperature.Nut A

5. Tighten:
Spark plug
NOTE:
Before installing the spark plug, clean the
gasket surface and spark plug surface. Also,
it is suggested to apply a thin film of anti-
seize compound to the spark plug threads to
prevent thread seizure.
If a torque wrench is not available, a good
estimate of the correct tightening torque for a
new spark plug is to finger tighten a
the
spark plug and then tighten it another 1/4 to
1/2 of a turnb
.

3. Install:
Timing chain tensioner
Installation steps:
While lightly pressing the timing chain
tensioner rod by hand, turn the tensioner
rod fully clockwise with a thin screwdriver
1
.
NOTE:
Make sure that the tensioner rod has been
fully set clockwise.
With the timing chain tensioner rod
turned all the way into the timing chain
tensioner housing (with the thin screw-
driver still installed), install the gasket and
the timing chain tensioner 2
onto the cyl-
inder block.
WARNING
Always use a new gasket.
Tighten the timing chain tensioner bolts
3
to the specified torque.
NOTE:
The “UP” mark on the timing chain ten-
sioner should face up.

4. Turn:
Drive coupling
(several turns counterclockwise)
5. Check:
Turn the drive coupling counterclock-
wise, and then check if cylinder #1 is at
TDC of the compression stroke with a
dial gauge.

Make sure that the camshaft punch
marks are aligned with the arrow marks

CAUTION:
Do not use a torque wrench to tighten
the bolt to the specified angle.
Tighten the bolt until it is at the speci-
fied angle.
NOTE:
When using a hexagonal bolt, note that the
angle from one corner to another is 60°.

EPOWRCONNECTING RODS AND PISTONS
9. Tighten:
Connecting rod nuts
WARNING
Replace the connecting rod bolts and
nuts with new ones.
Clean the connecting rod bolts and nuts.
NOTE:
The tightening procedure of the connecting rod
nuts is angle controlled, therefore tighten the
nuts using the following procedure.
Tightening steps:
Tighten the connecting rod nuts to the
specified torque.
T R..
Connecting rod nut:
1st:
20 N  m (2.0 kgf  m, 14 ft  lb)
Tighten the connecting rod nuts further to
reach the specified angle 120°.
T R..

Final:
Specified angle 120
± 5°
WARNING
When the nuts are tightened more than
the specified angle, do not loosen the
nut and then retighten it.
Replace the bolt and nut with a new one
and perform the procedure again.
CAUTION:
Do not use a torque wrench to tighten
the nut to the specified angle.
Tighten the nut until it is at the speci-
fied angle.
NOTE:
When using a hexagonal nut, note that the
angle from one corner to another is 60°.
