9-26ENGINE <1.8L Engine> -Service Adjustment Procedures
TIMING BELT TENSION ADJUSTMENTNOSFGBCThere are two access holes provided in the timing belt front
lower cover. The two access holes can be used to readjust thetension of the timing belt, by following the procedures
described below, without the necessity of removing the timing
belt front lower cover. Note, however, that timing belt “B”,
which drives the right silent shaft, cannot be adjusted unless
the cover is removed.
(1) Turn the steering wheel all the way to the left.
(2) Remove the left side undercover panel.
NOTEThis work is done so that the crankshaft can be turned.
(3) Place a piece of wood against the engine oil pan and jack
(4)
:tmove the engine mounting bracket.
(5) Remove the timging belt front upper cover.
(6) Remove the four spark plugs.
(7) Turn the crankshaft clockwise and check the timing belt
condition.

(9) Remove the air conditioner drive belt and the alternator
drive belt.
(10)Remove the access cover (two places). There are easily
removed by inserting a screwdriver into the slots indicated
by the raised arrows in the timing belt cover and twisting.
(1l)lnser-t a socket wrench [a 14 mm (.55 in.) box wrench]
through the hole in the access cover and loosen the timing
belt tension bolt and nut.
Caution
The timing belt tension bolt and nut need only be
loosened
180”-200”. Any further loosening might re-
sult in their falling off inside the timing belt cover.

(12)Turn the crankshaft clockwise by two teeth of the camshaft
sprocket.
(13)First tighten the timing belt tensioner installation bolt (on
the lower side), and then tighten the tensioner spacer
(upper side).Caution
Be sure to tighten the bolt (lower side) first. If the
tensioner spacer of pivot side is tightened first, the
tensioner will rotate with it and belt tension may
become loose.
(14)lnstall the access cover. The access cover may be easily
installed by passing the hooks between the guides and
sliding it in.
(15)lnstall the air conditioner drive belt and alternator drive belt
and adjust the slack.
(16)lnstalI the timing belt front upper cover.
(17)lnstall the engine mounting bracket.
(18)lnstalI the spark plugs.
(19)lnstall the left side undercover panel.
LASH ADJUSTERS CHECKNO9FEABaO
If an abnormal noise is heard from the lash adjusters check asfollows.
(I) After warming up the engine, stop it.
(2) While installed to the cylinder head, press the part of rockerfeel very hard if the lash adjuster condition is normal.
(3) If, when pressed, it easily descends all the way downward,
(4) If there.is a spongy feeling when pressed, air is probably
cause is probably an insufficient amount of engine oil, or
damage to the oil screen and/or screen gasket.
(adding oil or repair), warm up the engine and drive at low
speed for a short time. Then, after stopping the engine andthis procedure a few times to bleed out the air from the oil.

OlA0550SERVICE POINTS OF REMOVAL
NO9KBBCa2. REMOVAL OF ENGINE MOUNT BRACKET
a(1) Jack up the vehicle after placing a wooden block
:.between the jack and the engine’s oil pan.
CautionJack up carefully so as not to apply an excessive
load to the various parts.
(2) Remove the engine mount bracket.
19. REMOVAL OF TIMING BELT
(1) Turn the crankshaft clockwise and align the timing
marks.Caution
The crankshaft must always be turned clockwise.
(2) Make a mark on the back of the timing belt indicating
the direction of rotation so it may be reassembled in thesame direction if it is to be reused.
(3) Loosen the bolt and tension spacer of the timing belt
tensioner.(4) Move the timing belt tensioner to the water pump side
and loosely tighten the bolt so that the tensioner
doesn’t return; then remove the timing belt.
NOTE
If the timing belt is to be re-used, use chalk to’mark (on
its flat side) an arrow indicating the clockwise direction.
Caution
1.As water or oil on the belt can seriously reduce
its usable life, ensure that the timing belt,
sprocket, and tensioner stay clean and dry whileremoved, and never wash them. Parts that haveic
*become too dirty should be replaced.
2. When any of the parts are oily, check to see
whether there are any oil leaks in any of the oil
seals or the camshaft oil seal on the front of the
engine.
