Checking Drive BeltsEBS00LPY
●Before inspecting the engine, make sure the engine has cooled down; wait approximately 30 minutes
after the engine has been stopped.
●Visually inspect all belts for wear, damage, or cracks on contacting surfaces and edge areas.
●When measuring deflection, apply 98 N (10 kg, 22 lb) at the ▼ marked point.
CAUTION:
When measuring belt tension immediately after belt is installed, first set the tension to the standard.
Then, rotate crankshaft for more than two turns in order to eliminate variance in belt deflection
between the pulleys. Re-measure and adjust the tension to the standard.

Parts Requiring Angular TighteningNJEM0047Use an angle wrench for the final tightening of the following
engine parts:
a) Cylinder head bolts
b) Main bearing cap bolts
c) Connecting rod cap nuts
d) Crankshaft pulley bolt
Do not use a torque value for final tightening.
The torque value for these parts are for a preliminary step.
Ensure thread and seat surfaces are clean and coated with
engine oil.
SEM164F
Liquid Gasket Application ProcedureNJEM00481.Use a scraper to remove all traces of old liquid gasket
from mating surfaces and grooves. Also, completely clean
any oil from these areas.
2.Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
Be sure liquid gasket diameter is as specified.
AEM080
3.Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
4.Assembly should be done within 5 minutes after coating.
5.Wait at least 30 minutes before refilling engine oil and
engine coolant.

InspectionNJEM0088Before inspecting the engine, make sure the engine has
cooled down; wait approximately 30 minutes after the engine
has been stopped.
Visually inspect all belts for wear, damage, or cracks on con-
tacting surfaces and edge areas.
When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point.
When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning the crankshaft two turns or more, re-adjust to
the specified value to avoid variation in deflection
between pulleys.
Tighten idler pulley lock nut by hand and measure deflec-
tion without looseness.
