InspectionNJEM0088+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 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.

+If the belt deflection of the current belt is out of the ªLimit
for re-tighteningº, adjust to the ªAdjusted valueº.
+When checking belt deflection immediately after
installation, first adjust it to the specified value. Then,
after turning crankshaft two turns or more, re-adjust it to
the specified value to avoid variation in deflection
between pulleys.
+Make sure the belts are fully fitted into the pulley grooves
during installation.
+Handle with care to avoid smearing the belts with oil or
cooling water etc.
+Do not twist or bend the belts with strong force.

Secondary Timing ChainNJEM0093CAUTION:
+After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike piston heads.
+When installing camshafts, chain tensioners, oil seals, or
other sliding parts, lubricate contacting surfaces with new
engine oil.
+Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprockets, crankshaft pulley,
and camshaft brackets.
+When removing the oil pans, oil pump assembly and tim-
ing chain from engine, first remove the crankshaft posi-
tion sensor (TDC sensor).
Be careful not to damage sensor edges.
